Answer:
The cell body of a motor neuron is approximately 100 microns in diameter and as you now know. the axon is about 1 meter (1,000) millimeter in length.
Explanation:
So the axon of a motor neuron is 10,000 times as long as the cell body is wide.
How can transmission,reflection, and absorption affect a wave
Answer:
When a light wave with a single frequency strikes an object, a number of things could happen. The light wave could be absorbed by the object, in which case its energy is converted to heat. The light wave could be reflected by the object. And the light wave could be transmitted by the object.
how is hair grown? give me a really really really detailed answer
Hair grows out of little pockets in your skin, called follicles. Here's how it happens:
Your hair begins growing from a root in the bottom of the follicle. The root is made up of cells of protein.
Blood from the blood vessels in your scalp feeds the root, which creates more cells and makes the hair grow.
The hair gets pushed up through the skin as it grows, passing an oil gland along the way. The oil gland adds oil to the hair and keeps it shiny and soft. It can make it greasy, too. That's why you need to wash your hair.
The hair dies by the time it is long enough to poke out through the skin. Yes, hair is dead. That's why it doesn't hurt to get a haircut.
Hair on the rest of your body goes through this same process, but the whole cycle only lasts for a month or so. That's why body hair does not grow very long in length like the hair on your head does.
Here are some facts about follicles and your hair:
You are born with all of the follicles you will ever have — about 5 million.
You have about 100,000 follicles on your scalp, which is the skin on your head.
Hair grows very fast and male hair grows faster than female hair. The only part of your body that grows faster is bone marrow, the soft stuff inside your bones. The hair on your head grows about 6 inches a year. So, even though it's one of the fastest-growing things on your body, it takes a while to grow it really long.
Some follicles stop growing hair as you get older. This happens more in some people than in others. That's why some people get thinner hair when they get older, or go bald.

how can temperature and precipitation affect tree growth
Answer:
When there is present low precipitation or low moisture supply, together with high temperature, the limited growth is due to the close relationship which exists between turgidity and growth.
Explanation:
It is known, of course, that precipitation and temperature are not the only factors that have an effect on the growth of trees.
Answer:
Temperature can affect how heat and other gases correspond with the tree and can change the flow inside the tree. Precipitation can tell us how much water the tree is getting to absorb and grow with.

Humans process some foods by adding chemicals to reduce harmful bacterial growth. This allows foods to be edible for longer periods of time. Which best describes the advantages of food processing? control of density-independent limiting factors such as disease spread control of density-dependent limiting factors such as disease spread control of density-dependent limiting factors such as predation control of density-independent limiting factors such as predation
The statement that best described the advantage of food processing is that it controls density-dependent limiting factors such as the spread of diseases.
Processing foods through the addition of chemicals have the ability to kill off pathogens in foods, thus making the foods safer for consumption. The consumption of pathogen-free foods means that pathogenic diseases will be reduced to a minimum in a population.
The spread of diseases is a density-dependent limiting factor of a population. Density-dependent limiting factors have either positive or negative correlations with population growth. Other density-dependent limiting factors include competition and predation.

What would happen if a macromolecule was missing?
Answer:
If you were to not have any proteins in your being, you would eventually die. This is because all your cells need proteins to function. Without proteins, they cannot function.
Explanation:
If a macromolecule is missing, it will eventually affect your cell's functions and leads to the death of an individual.
What is a Macromolecule?A macromolecule may be defined as a type of very large molecule that is extremely important for the accomplishment of biophysical processes like metabolic functions, cellular needs, etc. Some examples of macromolecules are carbohydrates, proteins, nucleic acids, fats (lipids), etc.
According to the question, if macromolecules like carbohydrates are missing, the cells of an organism do not need energy for metabolic and cellular functions, and due to lack of energy, it will eventually die after some time. The same principle is followed by the other macromolecules as well.
Therefore, if a macromolecule is missing, it will eventually affect your cell's functions and leads to the death of an individual.

Once M’Kenna’s small intestine healed, she started eating foods with dairy again and these foods no longer made her sick. Lactase is an enzyme that helps break down foods with dairy. In a healthy system, lactase is released from the tips of the villi in the small intestine. Using this information, make a prediction for why the damage caused by celiac disease causes problems when a person eats dairy.
Answer:
Damage to the villi means less lactase released, so the body can't break down dairy.
Explanation:
If the small intestine is damaged, then that can mean that the villi are damaged. The villi usually release lactase, so this process will be compromised.
Less lactase released means that the body will have less of the enzyme required to break down lactose, the sugar present in dairy. Thus, individuals with celiac disease will struggle to digest dairy products

Explanation:
Cameron reads in his textbook that animal cells are composed of 90 percent water and 10 percent protein, carbohydrate, nucleic acid, lipid, and other molecules. He learns that homeostasis is the process by which this composition is maintained. How does an organelle in an animal cell control the content of water and other material in the cell?
a.the cell wall splits apart to allow water and materials to enter the cell and waste products to leave the cell
b.the cell membrane is selectively permeable,whic controls the movement of materials in and out of the cell by passive and active transport
c. vacoules in the cell open and draw in the only materials needed from outside the cell
d .lysosomes move out the cell to capture and bring back needed materials
Answer:
The correct answer is - option B. the cell membrane is selectively permeable, which controls the movement of materials in and out of the cell by passive and active transport.
Explanation:
The cell membrane is the most essential cell organelle that is mainly responsible for the regulation of homeostasis of the cell. It acts as a barrier between the outer environment and cell components are enclosed in the cell organelles and cytoplasm by regulating the movement of the material in and out of the cell.
This movement can be active or passive transport depending on the nature of the material as it is a selectively permeable membrane.
The correct answer is - option B.
