Part A
Begin by selecting a freshwater or marine aquatic ecosystem as a model for your food web. Be specific. Choose a specific lake. Or, if you choose an ocean ecosystem, identify its geographical area and depth. Keep in mind that deep-sea organisms live in a completely different environment than surface aquatic organisms.

Next, conduct research on the following conditions in the ecosystem you chose. They influence the types of organisms that can live there.

geographical features
temperature
depth/light availability
salinity
pH
unique features that contribute to the ecosystem, such as other bodies of water that connect to it, unusual chemistry, and climate
Using the information you gathered, write a paragraph that describes conditions in the ecosystem.


Part B
Now conduct research on the types of organisms that live in the ecosystem you chose. Note that quaternary consumers and even tertiary consumers can include land animals that rely on the animals in the aquatic ecosystem for food. Collect information based on these guidelines:

Producers: Identify 2-3 species.
Primary (or first-level) consumers: Identify 2-3 species.
Secondary (or second-level) consumers: Identify 2-3 species.
Tertiary (or third-level) consumers: Identify 2-3 species.
Quaternary (or fourth-level) consumers: Identify 1-2 species.
Write down the species you’ve identified for each consumer level in the ecosystem.

Part C
Using the organisms you identified in part B, create a food web for the ecosystem you chose. Use this sample food web for reference, although your food web will contain fewer organisms. Note that your food web does not have to include images, but you may include them if you choose. However, be sure to include arrows to indicate the direction of energy flow in your food web. Design your food web using any method listed below:

Use drawing or flowchart-building tools in a word-processing program.
Hand draw your food web, and then take a picture of it.
Use a graphic-design program.
Using the Insert Image button, insert an image of your food web in the answer space.

Part D
Changes in ecosystems can be attributed to natural causes, such as natural disasters, seasonal variations in climate, currents, and tidal activity. Many of these changes can affect the amount of food resources available in an ecosystem. Research one natural change that currently affects or could affect the aquatic ecosystem you chose. Use your food web model to explain how this change can affect the competition of food resources in your aquatic ecosystem.

Part E
In addition to natural factors, human activity can also alter ecosystems. Conduct research on a human activity that currently affects or can theoretically affect your chosen ecosystem. Use your food web model to explain how this change can affect the competition for food resources.

Answers

Answer 1

The break down of the  freshwater aquatic ecosystem  is given below.

Part A

For the purpose of this exercise, I will choose the Great Salt Lake in Utah, USA as my model for a freshwater aquatic ecosystem. The Great Salt Lake is the largest saltwater lake in the Western Hemisphere, and is known for its high salinity levels and unique chemistry.

The lake is fed by several rivers, including the Jordan and Bear rivers, and has no outlet, which contributes to its high salinity levels.

The lake also experiences seasonal changes in temperature and light availability, with warmer temperatures and more sunlight in the summer and cooler temperatures and less sunlight in the winter.

What is the freshwater aquatic ecosystem about?

Part B

The Great Salt Lake ecosystem is home to a variety of organisms at different consumer levels. Some examples include:

Producers:

Phytoplankton: Microscopic algae that are the base of the food web and are primary producersSodium chloride-tolerant plants like alkali bulrush and saltgrass

Primary Consumers:

Brine flies: these insects feed on the phytoplanktonbrine shrimp: these tiny crustaceans feed on the phytoplankton

Secondary Consumers:

Black brant and other waterfowl: these birds feed on the brine flies and shrimpWhite pelican: These birds feed on the brine shrimp

Tertiary Consumers:

Coyotes and foxes: These mammals feed on the waterfowl and other small animalsAmerican avocet: These birds feed on the brine flies and shrimp

Quaternary Consumers:

Humans: they may fish or hunt the aquatic species and use the lake's resources

Part C

This is a possible food web for the Great Salt Lake ecosystem:

Phytoplankton -> Brine Flies -> Black Brant -> CoyotesPhytoplankton -> Brine Shrimp -> Pelican -> FoxesSodium chloride-tolerant plants -> American avocet -> Humans

Part D

One natural change that currently affects the Great Salt Lake ecosystem is the seasonal variation in water levels. The lake's water level can fluctuate greatly depending on the amount of precipitation and evaporation.

During drought periods, the lake's water level can drop dramatically, which affects the competition for food resources in the ecosystem.

Part E

One human activity that currently affects the Great Salt Lake ecosystem is water diversion for irrigation and human consumption. The lake's water level is also affected by the diversion of water from the Jordan and Bear rivers, which feed into the lake. This water diversion decreases the amount of fresh water that enters the lake, which affects the amount of phytoplankton and other producers in the ecosystem.

Epithelial tissue lines the inside of hollow organs.  Therefore, option A is correct.

The body contains a variety of epithelial tissues. They are the primary tissue in glands and make up the covering on all of the body's surfaces, the lining of body cavities, and hollow organs. Protection, secretion, absorption, excretion, filtration, diffusion, and sensory reception are just a few of the many tasks they carry out.

In epithelial tissue, the intercellular matrix is sparse, and the cells are closely packed together. The cells have one surface that is free and not in contact with other cells since the tissues create covers and linings. Contrary to the free surface, a non-cellular basement membrane holds the cells to the underlying connective tissue. The epithelium and connective tissue cells produce a mixture of carbohydrates and proteins to form this membrane.

Answers

1. To calculate the slope of the ground surface on either side of Jim's Gas Station, an elevation survey would have to be taken to determine the change in elevation in relation to the distance traveled. This can be done with a topographic map or an altimeter.

What is topographic map?

A topographic map is a type of map that uses contour lines to show the shape of the land and its features.

2. The slope of the water table at Jim's Gas Station can be estimated by measuring the depth of the water table in relation to the topography of the land in the area. This can be done by measuring the depth of the water table at various points around the gas station and then plotting them to see how the depth of the water table changes with respect to the topography.

3. The direction of the pollution plume can be inferred by looking at the slope of the ground surface and water table. If the ground surface slopes downward away from the gas station, the pollution plume is likely to move in the same direction.

4. The houses and bodies of water that are threatened by this pollution plume are those that are located downhill from the gas station. The further downhill the houses and bodies of water are, the more likely they are to be affected by the pollution plume.

5. The path of the pollution plume at Jim's Gas Station can be predicted by looking at the slope of the ground surface and water table. This is because the pollution plume will move in the direction of the downward slope of the ground surface and water table. The path of the plume can be further refined by taking into account other factors such as wind direction and speed, temperature, and humidity. By taking all of these factors into consideration, a precise prediction of the path of the plume can be made.

After fluid passes through the entire proximal tubule, the fluid will enter the loop of Henle, option a is the right choice.

Filtrate movements from Bowman's pill to the proximal tubule and into the loop of Henle, which dives into the renal medulla earlier than returning to the renal cortex. From the loop of Henle, filtrate is transferred to the distal tubule and into the accumulating duct, in which it travels into the renal medulla for collection. The filtrate flows from the proximal tubule and into the Loop of Henle. The loop of Henle concentrates the filtrate, through casting off greater water from it, and passes it to the distal tubule. From the distal tubule it travels to the accumulating duct - now known as urine.

Does increasing muscle mass increase metabolism?

Answers

Yes, increasing muscle mass has been scientifically proven to positively affect metabolism. Muscle mass makes up the largest portion of an organism's metabolic rate, meaning that more muscle tissue will result in a higher metabolism.

Muscles require energy, including calories and nutrients, to function optimally and to be able to perform tasks such as lifting weights or climbing stairs. As such, adding more muscle mass increases the body's ability to burn calories even at rest due to increased caloric expenditure by the muscles.

Furthermore, an increase in muscle mass leads to improved insulin sensitivity and body composition, which can further contribute to an enhanced efficiency in caloric expenditure. In conclusion, it is clear that increasing muscle mass can lead to an increase in one's metabolic rate.

Definition Of nucleosome

Nucleosome is the structural building block of DNA packaging inside the chromosome. The packing problem of how to fit a very, very long stretch of DNA, that is, about a yard of DNA, inside a very small cell, which is about one hundredth of a millimeter in diameter, has fascinated scientists for a long time.

And it turns out how does the cell do this -- now -- remember that every single cell in the body has this problem -- is it coiled and super coiled around DNA in a lot of complicated ways.

The basic building blocks of the coil are the nucleosomes, which are basically the little blocks of histone proteins around which the DNA is wrapped, and they really look like beads on a string, except the beads have DNA wrapped around them rather than have DNA running through them, as in the case of the beads on a string.

In order to fit DNA into the nucleus, it must be packaged into a very compact structure known as chromatin. In the first step of this process, the DNA is compacted into 11 nm fibers representing a 6-fold compaction level. This is achieved through nucleosome assembly.

Each nucleosome consists of a core of octagonal octamers, which are assembled from histones H2A, H2B, H3 and H4 (or other histone variants in some cases) and a DNA segment that wraps around histone core. Adjacent nucleosomes are linked via “linking DNA”.

Genes are the material that carries the properties of the parent and are passed on to their filial or offspring. Genes are attached to chromosomes and chromosomes are contained in the nucleus or cell nucleus.

Chromosomes in the body are usually in pairs. In humans, there are 46 or 23 pairs of chromosomes. 22 pairs are autosomal chromosomes, namely the chromosomes that make up the body, such as the eyes, nose, legs, hands and other organs.

One more pair is called the genosome chromosomes, namely the sex chromosomes, the chromosomes that determine the sex of the individual. When the chromosomes pair X and X (XX), the sex is female. And if the chromosome pair is X and Y (XY), then the sex is male.

Chromosomes contain genes and the inherited genes are dominant and recessive. Dominant trait means, a trait that dominates and overpowers other traits. For example, both parents have olive and black skin tones. And it was obtained that all of his offspring had olive skin color.

This means that the olive skin color gene is dominant over the black skin color gene. The black gene is called a recessive gene, that is, a gene that is hidden and defeated.

The correct answer is Mosquito Bites. Bloodborne pathogens are infectious microorganisms that can be transmitted through contact with blood or other body fluids. Examples of bloodborne pathogens include HIV, hepatitis B, and hepatitis C, but mosquito bites are not considered a bloodborne pathogen.

Mosquito-borne diseases are those that are transmitted through the bite of an infected mosquito. These diseases can include dengue fever, West Nile fever, malaria, Japanese encephalitis, St. Louis encephalitis, yellow fever, St. Louis encephalitis and California encephalitis. Symptoms of these diseases can include fever, headache, nausea, vomiting, rash, muscle pain and in some cases, severe neurological disease.

Place the following events in the order they occur by listing their assigned letters in that order.

When formatting your answer, there should be no spaces or characters in between e.g. ABCDEF

A. Cas9 cuts both strands to generate a double strand break.
B. Cas9 unwinds dsDNA.
C. Cas9 complex scans dsDNA for PAM sequence.
D. Cas9 complex binds to dsDNA.
E. The programmable part of the guideRNA binds to its complementary sequence.
F. Cas9 REC domains binds to the guideRNA.

Answers

(ABCDEF) The Cas9 DNA recognition and cleavage processes are labeled A, B, D, C, E, and F in the following order. Following its recognition and binding of the sgRNA, Cas9 then attaches to the double stranded DNA. The dsDNA is then unwound and scanned for the protospacer adjacent motif sequence (PAM). When the PAM is found, the sgRNA attaches to its complementary sequence and causes two places on the DNA to be cleaved. The double stranded break is produced in this manner.

what are cleavage processes?

Following fertilization, the formation of a multicellular creature occurs by a process known as cleavage, in which the huge volume of egg cytoplasm is divided into several smaller, nucleated cells during a series of mitotic divisions.

what would be the fate of a lytic bacteriophage if the host cell died prior to the assembly stage?
The virus would infect new hosts.
The virus would not be able to infect new hosts.
The cell could still be revived by the virus.

Answers

The virus would not be able to infect new hosts, if the host cell died prior to the assembly stage.

In the lytic cycle, a phage acts like a normal virus: it hijacks its host mobile and makes use of the mobile's sources to make masses of latest phages, inflicting the mobile to lyse (burst) and die withinside the process. The lytic cycle results in the loss of life of the host, while the lysogenic cycle results in integration of phage into the host genome. Bacteriophages inject DNA into the host mobile, while animal viruses input with the aid of using endocytosis or membrane fusion. In the lytic cycle, the virus attaches to the host mobile and injects its DNA. Using the host's mobile metabolism, the viral DNA starts to duplicate and shape proteins. Then absolutely shaped viruses assemble. These viruses break, or lyse, the mobile and unfold to different cells to hold the cycle.

In 1907, Dr. Duncan MacDougall performed a series of experiments in which he attempted to measure the weight of the soul as it left a dying person. In his experiments, MacDougall placed a dying person on a scale and measured their weight immediately prior to and following death. MacDougall determined the change in weight to be approximately 21 grams. From these experiments, he concluded that the soul existe and has mass. What is the fundamental scientific flaw in his conclusions?

A. They are based on the concept of the soul, which is beyond the bounds of science.

B. They are based on the idea that the soul is made of matter, not energy.

C. They are based on the assumption that the soul remains in the body after death.

D. They are based on the concept that the soul can be measured using data.

Answers

In order to prove that souls have a tangible weight, Dr. MacDougall performed experiments on six terminal patients. Out of the six individuals, only one shed roughly 21 grams of weight.

Due to the limited sample size, the procedures utilized to verify the hypothesis, and the fact that just one of the six subjects met the hypothesis, this experiment was widely considered as defective and unprofessional.

What are theories and an example?

A assertion that reflects the link between precisely two variables is referred to as a straightforward hypothesis. a dependant and a single independent. Take the statement "Smoking is a significant cause of lung cancer" as an example. Smoking is an independent variable that influences the dependent variable, lung cancer.
