The cells have different shapes and perform different functions in the body  is the primary difference between a liver cell and a skin cell.

What is liver cell?

Hepatocytes have an eosinophilic cytoplasm, which reflects their abundance of mitochondria, and basophilic stippling, which results from their abundance of free ribosomes and smooth endoplasmic reticulum.

With advancing age, brown lipofuscin granules are also seen alongside sporadic, unstained cytoplasmic regions; these correspond to cytoplasmic glycogen and lipid storage lost during histological preparation.

Hepatocytes can regenerate and have an average lifespan of 5 months.

Distinguish between an antibiotic and a pathogen.​

Answers

An antibiotic is designed to kill bad cells to help aid illnesses. However, a pathogen is like a virus or a bacteria that can give a disease. Doctors observe pathogens on a atomic and cellular level to alienate the pathogens weaknesses and what does or doesn't kill it. An antibiotic is commonly used to kill these pathogens and prevent infections.

Basically, the big difference between an antibiotic and a pathogen, is that an antibiotic is used as a source of protection and a pathogen is a seperate living virus (disease). Both are key components of finding cures for harmful viruses and illnesses.

how much energy moves up from one trophic level to the next in the energy pyramid​

Answers

Answer: Only about 10% of energy is transferred from one trophic level to the next. Most of the rest of the energy is lost through heat (energy expended, metabolic process, respiration) as it transfers along each level. The reason for this energy loss is found in the second law of thermodynamics which states: that as energy is transferred energy is lost.

happened

Answers

Answer:

This is an example of natural selection. There were two types of moth colors, white and black and white. Before the industrial revolution, the environment had white trees, meaning that the white moths can blend in. The black moths are more likely to be eaten because they stick out. Now that the trees are black, the white moths stick out more causing there to be more black moths.

Velocity is The amount of time it takes an object to move from point A to point B. Therefore, option B is correct.

What is velocity?

When an item is moving, its velocity is the rate at which it is changing position as seen from a particular point of view and as measured by a certain unit of time. The meter per second (m/s) is the accepted unit of velocity magnitude (also known as speed). The various forms of velocities include uniform, variable, average, and instantaneous velocities.

There are countless practical uses for velocity, but one of the more frequent ones is figuring out how quickly you (or anything in motion) will get somewhere from somewhere.
