is adding sodium to water endothermic or exothermic
Answer:
exothermic
Explanation:
Answer:
It takes just slightly more energy to separate the ions from one another than is released from the water molecules surrounding the ions. This means just slightly more energy must be put into the solution than is released back into the solution; therefore dissolving table salt in water is endothermic.

examples of: *
O Biotic Factors
Abiotic Factors
Populations
Answer:
Water, sunlight and soil composition are examples of abiotic factors.
Explanation:
Abiotic factors are those found in the environment and are devoid of life, being chemical and physical factors that are part of an ecosystem.
Examples of abiotic factors are water, wind, soil and its components, the degree of humidity or temperature, and are capable of influencing environmental conditions and living beings or biotic factors.
Regarding the other options:
Abiotic factors and populations correspond to living beings —plants and animals, for example— different from abiotic factors.

Why are there differences between cell types?
Answer:
There are many different types of cells. For example, in you there are blood cells and skin cells and bone cells and even bacteria. Here we have drawings of bacteria and animal cells. Can you tell which depicts various types of bacteria? However, all cells - whether from bacteria, human, or any other organism - will be one of two general types: prokaryotic or eukaryotic. In fact, all cells other than bacteria will be one type, and bacterial cells will be the other. And it all depends on how the cell stores its DNA.

Parrotfish are herbivores that are found in coral reefs. To escape predation, a parrotfish will graze with a rabbitfish, which has venomous spines at the end of its pelvic fins. The rabbitfish does not benefit from this relationship. Which type of relationship do the parrotfish and the rabbitfish have in the coral-reef environment? (5 Points) [Control]Commensal [Control]Mutualistic [Control]Predator-prey [Control]Parasit
Answer:
Commensal
Explanation:
Hope this helps
The type of interaction between the parrotfish and rabbitfish in coral reefs is Commensal.
What is Species interaction?The population of one species interacts with the population of other species that live in the same locality is called species interactions.
Here, in this scenario parrotfish are grazing with rabbitfish in order to escape from predation. As rabbitfish have venomous spines at the end of their pelvic pins and protect the organisms of parrotfish from predators. In this interaction, parrotfish get the benefit to escape from predators and survive freely, while rabbit fish doesn't benefit from this interaction, this interaction is called Commensalism.
Therefore, the type of interaction between the parrotfish and rabbitfish in coral reefs is Commensal.

Where does the organic material in soil originate?
a. physical weathering
b. chemical weathering
C. decomposing plant and animal matter
d. the atmosphere
Answer:
C. decomposing plant and animal matter
Explanation: Trust me
Most of the organic materials come to the soil from decomposing plants and animal matter, so option C is correct regarding the statement. Microbes decompose dead organisms so that their nutrients go into the soil and are further used by others.
What is the role of decomposers in the ecosystem?Plants require water, carbon dioxide, minerals from the soil, and other resources to produce food in an ecosystem, and heterotrophs such as humans and animals such as goats take these resources from the plants. After these plant and animals die, microbes decay them and release nutrients into the soil, where they can be taken up by plants and other organisms, allowing nutrients to be recycled back into the ecosystem.
Different organic substances and molecules, such as carbon, nitrogen, etc., remain within the soil and further enter the atmosphere in different ways. The organic matter that present in the animal fecal matter enter to the soil too.
Hence Most of the organic materials in the soil come from decomposing plants and animal matter, so option C is correct.

What type of genetic material do viruses contain ?
If a plant of a maple tree has more chloroplasts than the leaf of a tomato plant, then
Answer:
This question appears incomplete
Explanation:
This question appears incomplete. However, generally speaking, the higher the chloroplasts present in a plant, the higher the rate of photosynthesis that occurs in that plant. This is because chloroplasts are cellular organelles that serve as sites in which photosynthesis occur. They are found in green plants and green algae.
Photosynthesis is the process in which green plants produce there own food by absorbing sunlight from the atmosphere in the presence of carbon dioxide and water. Hence, it can also be said that an increase in the number of chloroplasts will lead to an increase in the amount of food produced by a plant (for itself).
From the description above, it can be said that the plant of a maple tree has a higher rate of photosynthesis and hence produced more food (for itself) than the leaf of a tomato plant.
Chloroplast also contain a green pigment called chlorophyll which is responsible for the green colour in green plants. Hence, an increase in the number of chloroplasts in a plant could indirectly imply greener plant. Hence, the plant of a maple tree could have greener leaf than the leaf of the tomato plant.

What does the liver do? Please describe almost everything since I'd love to understand the liver completely!
Answer:
the liver processes the blood and breaks down balances and creates the nutrients and also metabolizes drugs into forms that are easier to use for the rest of the body or that are nontoxic more than 500 vital functions have been identified with the liver
Answer:
1. Bili production
2. Protein and cholesterol production
3. Regulates aminoácids in the blood
4. Iron processing in hemoglobin
5. Toxin processing
UreaPoisonsMedicine residue6. Vitamin and protein storage
Explanation:
Think of the liver as a form of "customs" for the body. The liver processes and regulates what enters the blood stream, as well as getting rid of harmful toxins that could damage the body. An example of this would be processing dead blood cells. These cells contain a substance called bilirubin, which breaks down the "heme" in the blood cells once they die/are damaged. Should there be a problem with the liver, the bilirubin can build up and cause a condition called jaundice. This is harmful as if damages elastin-rich tissue.
However, if the liver functions properly, it produces bile through which bilirubin can be disposed of. The liver produces a bile that is stored in the gallbladder, which then can be ejected into the duodenum (intestine) to liquified food. This is essential to help with the digestion and absorption of nutrients.
The liver plays a huge role in metabolism. It synthesizes proteins as well as amino acids. Some of the proteins sythnesized are used for blood clotting factors. It also does lipid metabolism, where it produces cholesterol.
Any build up of toxins in the body goes through the liver in order to be excreted. This excretion is done through bile of through urine. The name "urea" is produced in the blood-stream, and can be fatal if not treated. Fortunately, the liver does the job as it extracts it from the bloodstream and ejects it.
Finally, the liver builds up "fat" as it processes lipids and glucose. Should there not be enough glucose, the liver breaks down its glycogen storage to act as an "emergency reserve", thus providing energy to the body.
Check out John Hopkins Medicine website if you want to learn about the liver more in-depth. It's a very complex organ, and there are whole careers based off of studying it alone.
