Chewing of food is not a chemical process in the digestive system, but a mechanical process. Therefore, the correct option is D.
What is Digestive system?A collection of organs called the digestive system help break down food into smaller molecules that the body can absorb and use for energy, growth, and repair. It consists of anatomical organs such as the anus, esophagus, stomach, small and large intestine, liver, and pancreas. Food is broken down physically and chemically by the digestive system, which also absorbs nutrients and gets rid of waste.
Chemical process of digestive system involves Bile interacting with digested food in the small intestine, acids reacting with food particles in the stomach and saliva breaking down food particles while the mechanical process involves chewing of food.
Therefore, the correct option is D.

What needs to happen in order for two populations to be isolated?
Answer:
Isolation means that organisms of the same species are separated, and happens when there is something between the organisms that they can't cross.
Explanation:
Organisms become isolated as a result of environmental change. The cause of isolation can be gradual, like when mountains or deserts form, or continents split apart.
Kudzu, a plant native to eastern Asia was introduced into America in 1876. In 1935, Kudzu was planted along southern roadways to control soil erosion. Adding a foot of vine a day in the spring and summer
kudzu quidity grew out of control. Why can introducing a new species to an existing ecosystem often be a disaster?
A The new species can create excess nutrients in the soil that can damage native species
The series can harminative anime and damage the ecosystem
Answer:
Due to lack of biological gent.
Explanation:
Introducing a new species to a new ecosystem often leads to a disaster because of the absence of bioagent for that species. Bioagent are those organisms which has the ability to control other organisms by feeding on them. A new species does not make problem in its old or original ecosystem due to the presence of controlling agents but in the new ecosystem there is no bioagent that can stop its growth so that's why sometimes the introduction of new species leads to a disaster.

The reindeer migrate from north to south in the summer months to reach
more fertile feeding grounds. They migrate to the north in winter months.
The reindeer populations migrate to an intermediate location in Norway to
mate and then diverge to the northernmost and southernmost regions to
avoid competition for food.
There are two species of reindeer in Norway. The northernmost species
reproduces in the winter, causing an increase in population size. The

Why is it important for nitrogen to be more abundant in our atmosphere than oxygen?
A. Oxygen is only breathable if diluted with nitrogen.
B. Nitrogen and oxygen combine to produce weather that is essential for life.
C. Oxygen must be diluted because it is a highly combustible gas.
D. Nitrogen is a heavy molecule that pulls oxygen, a light molecule, to the surface for oxygen-dependent life to use.
(also report this idiot called americanlove if spot him, for the last 2 hours he has been going to almost every post just to steal points for no reason)
Answer:
Choice C
Oxygen must be diluted because it is a highly combustible gas.
Oxygen must be diluted because it is a highly combustible gas is important for nitrogen to be more abundant in our atmosphere than oxygen.
Why nitrogen is important?Nitrogen is extremely important to living material. Plants, animals and humans could not live without it.
The major source of nitrogen is the atmosphere. It exists as a colorless, odorless, nontoxic gas and makes up about 78 percent of the atmosphere. Nitrogen is also found in the Earth's crust as part of organic matter and humus.
Our atmosphere's nitrogen gas is a molecule made up of two nitrogen atoms. This kind of nitrogen can't be utilized by plants directly. Before it can be utilized by plants, nitrogen needs to be transformed into other forms.
Therefore, Oxygen must be diluted because it is a highly combustible gas is important for nitrogen to be more abundant in our atmosphere than oxygen.

Sickle cell anemia is an inherited form of anemia - a condition in which there aren't enough healthy red blood cells to carry adequate oxygen throughout your body.
Normally, your red blood cells are flexible and round, moving easily through your blood vessels. In sickle cell anemia, the red blood cells become rigid and sticky and are shaped like
sickles or crescent moons. These irregularly shaped cells can get stuck in small blood vessels. How does sickle cell anemia affect the blood flow in a human?
Answer:
RBCs are round red blood cells that easily move through blood vessels and carry oxygen with them to provide cells oxygen. In sickle cell anemia, the shape of the red blood cells is like sickles or crescent moons.
These cells occur due to mutation on the gene that produces this protein which results in rigid, sticky cells that can get stuck in small blood vessels and blocks the flow of blood, oxygen to parts of the body.

Explanation:
Compare and contrast gradualism and punctuated equilibrium. Provide at least one comparison and one difference in your answer. You may use examples for each if that helps you with answering the question.
Answer:
Gradualism and punctuated equilibrium both are the process of evolution of species over time. However, the gradualism process involves the evolution that occurred slowly, occurring in small periodic changes in the gene pool over a long period of time. Whereas Punctuated equilibrium takes place there are longer periods of apparent stasis interrupted by the sudden change.
They both help in finding the relative change in evolution rate and assist in the study of the anatomical changes occurred during the evolution in different kind of animals or organisms.
