Hope this helps!
Answer 2
Answer: Through The Respiratory System, The Oxygen Enters The Body Then Is Transported As Oxyhaemoglobin To the Cells with the help of cardiovascular system. 

The Cardiovascular system relates with the digestive system for an optimum heart rate. The Digestive system produces Nutrients, with the help of the Cardiovascular system transports these nutrients where it is needed.

There For, That being said, The Human Body Is reached in healthy equilibrium if all these systems work together in harmony

How are tapeworm zygotes passed out of the body?

Answers

“Once inside the body, the tapeworm head attaches to the inner wall of the intestines and feeds off the food being digested. Pieces of the tapeworm break off and come out of the body in feces (poop), along with the eggs they contain. If this infected poop gets into soil or water, it can infect other people or animals.”

The body needs what in only small amounts, but these organic molecules are an important part in helping perform cellular reactions?

Answers

Answer:

Vitamins

Explanation:

Vitamins are the organic compounds that are needed by body in small amounts. Most of the vitamins are not synthesized in human body and should be supplemented with food. Vitamins serve as coenzymes or part of coenzyme which are required for the activity of respective enzymes. Hence, vitamins an important part in helping perform cellular reactions.

Vitamins. They are needed in small amounts for chemical reactions in the body, and they are also organic.

The fur color of the adult northern seal, created by a dark brown pigment, is due to a specific enzyme. Suggest reasons why baby seals are born with a pure white coat.

Answers

Answer and Explanation:

Even though Northern seals display a dark brown skin color, their pups are born with a fluffy white coat. This allows them to camouflage with the environment as they are unable to swim like the adults, keeping them away or hidden from predators.

Once they are around three weeks old, they start to lose this layer and begin to look like the "normal" seals.

Moreover, due the predominant climate in which they live, the color of the fur depends on genes and, therefore, enzymes. These enzymes are present during cold temperatures and, due to the warm conditions of the womb, these enzymes are denatured. After the seal pup is born, its cells produce a higher amount of enzymes to adjust to the temperature of their habitat and stays with the brown color to maintain homeostasis.

List four different types of evidence that support evolution. Name and explain them.

Answers

Answer:

the explanation is in the answer...

Explanation:

Anatomy. Species may share similar physical features because the feature was present in a common ancestor (homologous structures).

Molecular biology. DNA and the genetic code reflect the shared ancestry of life. DNA comparisons can show how related species are.

Biogeography. The global distribution of organisms and the unique features of island species reflect evolution and geological change.

Fossils. Fossils document the existence of now-extinct past species that are related to present-day species.

Direct observation. We can directly observe small-scale evolution in organisms with short lifecycles (e.g., pesticide-resistant insects).
