1. Identify What characteristic is used to
determine whether an organism is a first or
second-level consumer
Answer:
first-level consumers are mostly herbivorous animals, second-level consumers are carnivores that prey on first-level consumers.
Explanation:
Primary consumers cannot eat anything but plants and secondary consumers evolved to be able to hunt primary consumers because they are usually larger and need more energy than plants could provide.
First-level consumers are always herbivores organisms that depend only on the producer or autotrophic plants whereas Second-level consumers get their energy from herbivores and producers in their ecosystems.
Trophic levelsProducers are the first trophic level. Herbivores are the second trophic level. First-level consumers do not eat other consumers, only plants or other producers.
First-level consumers are always herbivores organisms that depend only on the producer or autotrophic plants. Second-level consumers get their energy from herbivores and producers in their ecosystems.

Explanation:
A Chlorella cell viewed through a microscope is 0.00005 m wide when the magnification is 2000.
What is the actual size of the cell?
Answer:
0.0025micrometer.
Explanation:
To calculate the actual size of the image, the formula to be used is
Actual size=Image size÷magnification.
The image size is 0.00005 wide
Magnification is 2000
First, convert the image size to micrometer.
=0.00005 × 1000000
50micrometers.
Actual size= 50÷2000
Actual size = 0.0025
The actual size of the cell will be
"0.0025".
MagnificationAccording to the question,
Image size = 0.00005 or,
= 0.00005 × 1000000
= 50 micrometers
Magnification = 2000
We know the relation,
→ Actual size = [tex]\frac{Image \ size}{Magnification}[/tex]
By substituting the above values,
= [tex]\frac{50}{2000}[/tex]
= 0.0025
Thus the above answer is appropriate.

Answer:
D
Explanation:
I chose it before .
Answer:
It is D because communicable diseases, also known as infectious diseases or transmissible diseases, are illnesses that result from the infection, presence and growth of pathogenic (capable of causing disease) biologic agents in an individual human or other animal host.
SO with the procces of elemination you can see that you can't contract cancer because that is something that can be inherited. Chronic Respiratory diesase can be inherited or developed throughout the years same as diabetes. Hence the answer being D

Describe the information displayed by ecological pyramids Use all three pyramids (number, biomass, and energy in your answer.
Explanation:
Edit
An ecological pyramid (also trophic pyramid, Eltonian pyramid, energy pyramid, or sometimes food pyramid) is a graphical representation designed to show the biomass or bioproductivity at each trophic level in a given ecosystem.
A pyramid of energy represents how much energy, initially from the sun, is retained or stored in the form of new biomass at each trophic level in an ecosystem. Typically, about 10% of the energy is transferred from one trophic level to the next, thus preventing a large number of trophic levels. Energy pyramids are necessarily upright in healthy ecosystems, that is, there must always be more energy available at a given level of the pyramid to support the energy and biomass requirement of the next trophic level.
A pyramid of energy shows how much energy is retained in the form of new biomass at each trophic level, while a pyramid of biomass shows how much biomass (the amount of living or organic matter present in an organism) is present in the organisms. There is also a pyramid of numbers representing the number of individual organisms at each trophic level. Pyramids of energy are normally upright, but other pyramids can be inverted or take other shapes.
Ecological pyramids begin with producers on the bottom (such as plants) and proceed through the various trophic levels (such as herbivores that eat plants, then carnivores that eat flesh, then omnivores that eat both plants and flesh, and so on). The highest level is the top of the food chain.

Use each of the terms below just once to complete the passage:

cell membrane
homeostasis

balance
selective permeability
Living cells maintain a homeostasis by controlling what materials enter and leave. Without this ability, the cell cannot maintain balance and will die. The cell must regulate internal concentrations of water, Glucose , and other nutrients and must eliminate waste products. Homeostasis in a cell is maintained by the Cell membrane, which allows only certain particles to pass through and keeps other particles out. This property of a membrane is known as Selective permeability. It allows different cells to carry on different activities within the same Organism.
Egg Osmosis Lab
Students in Biology class conducted a lab experiment to demonstrate osmosis using chicken eggs. The raw eggs were first soaked in vinegar for 24-48 hours to dissolve the shell. What was left was a very simple cell with a cell membrane. The eggs were massed, observed. and the data was recorded in the table below. On the first day of the lab the students placed their eggs into sugar syrup and left them overnight. The next day in the lab the eggs were removed from the syrup, carefully dried, observed, and massed again. Next the eggs were placed in distilled water and left overnight. The following day the eggs were removed from the water, carefully dried, observed, and massed.
Mass of egg (grams)
Appearance of egg
Day 1 (initial)
80.8
Transparent, squishy, feels sort of like a water balloon.
Day 2 (after syrup)
63.2
Egg feels softer and empty or deflated. It has shrunk and appears much more yellow.
Day 3 (after distilled water)
105.3
Egg is very large and feels like it might burst.
Describe what happened to the egg when it was placed into the sugar syrup in terms of osmosis.
Was the sugar syrup a hypertonic, hypotonic, or isotonic solution?
Describe what happened to the egg when it was placed into the distilled water in terms of osmosis.
Was the distilled water a hypertonic, hypotonic, or isotonic solution?
Answer:
Woah, woah, woah. Dude you put way too much. Nobody's gonna do a whole packet/assignment for you even for 50 points lol. And that's against the rule of the website (you can be punished if you're caught). But here's some osmosis basics.
Explanation:
If the cell has more water than its environment, it is hypertonic (think hyper like when you have a lot of sugar) The cell will want to release water. This may cause the cell to shrivel or shrink.
If the cell has less water than its environment, it is hypotonic (think hippos. they like to eat. hippo=hypo) The cell will absorb water, which may cause the cell to expand, swell, or even pop.
If the cell has the same amount of water/ proportion of water to other materials then nothing will really happen, and it will be isotonic. (Think isolated, where it doesn't have any interactions with other things.)
Solute= Thing being dissolved. (salt, sugar, etc.)
Solvent= Thing that dissolves the solute. (water, etc.)
Solution= The mixture of solute and solvent. (water + salt, etc.)
For some of the hypotheticals on this just think of what would happen if you did some of these experiments. What do you think would happen? Do research, and next time, don't post your whole packet lol. It's a waste of your points. And when you ask questions, take your time to formulate and describe the question as clearly as you can, so that we can help. Don't just copy and paste your lab assignment.
Thanks for asking your question,

The density of solid aluminum is 2.70 g/cm3. If a 1g piece of aluminum is dropped in a cup of water, what will happen to the aluminum? (The density of water is 1.00 g/cm3.) It will sink to the bottom. It will float to the top. It will hover in the middle. It will move up and down.
Answer:
The correct answer is: It will sink to the bottom
Explanation:
Density is the mass of substance per volume. If we compare the density value of water (1.00 g/cm³) and aluminum (2.70 g/cm³), we can see that:
density aluminum > density water
(2.70 g/cm³) > (1.00 g/cm³)
Thus, when we put solid aluminum in a cup of water, the aluminum will have more weight than surrounding water, so it will drop to the bottom of the cup.
If a 1g piece of aluminum is dropped in a cup of water It will sink to the bottom. Therefore option A is correct.
When comparing the densities of two substances, the denser substance tends to sink while the less dense substance tends to float.
In this case, the density of aluminum (2.70 g/cm3) is greater than the density of water (1.00 g/cm3). Therefore, when the 1g piece of aluminum is dropped into the cup of water, it will be denser than the water and sink to the bottom of the cup.
Option B, C, and D are incorrect because they describe scenarios where the aluminum would need to be less dense than water in order to float or hover in the middle.
Therefore option (A) It will sink to the bottom is correct.

Nerve cells, also known as neurons, are the basic building blocks of the nervous system. They are responsible for transmitting electrical and chemical signals throughout the body. Neurons have a cell body, which contains the nucleus and other organelles, and specialized extensions called dendrites and axons.
Dendrites receive signals from other neurons, while axons transmit signals to other cells, such as other neurons or muscles. The signals are transmitted across a small gap called a synapse, which can be chemical or electrical. Neurons are specialized for the rapid transmission of information, and are capable of generating electrical impulses called action potentials that travel along their axons.
