Why is the homeostasis of glucose important to the entire body and its cells?
Ugo [173]

Answer:

All cells get energy from glucose

Explanation:

The main source of energy for all the metabolic process and function of body organ individually and as one entity is glucose. Thus, there is essential requirement to transport glucose to all the cells within the body. Insulin and glucagon hormone regulates, control and facilitates the transmission and production of glucose. Both these hormones works opposite to each other, hence a proper balance is to be maintained for producing adequate amount of glucose

1. Increased efforts to conserve areas such as rain forests are necessary in order to
Nataliya [291]

Answer:

1. Protect biodiversity

2. An indicator species

3. Biomagnification

4. Cutting down all the trees for lumber

5. Bioaccumulation

Explanation:

1. Conserving areas such as rain forests protect biodiversity because rain forests hold one of the highest biodiversity. They carry different types of resources that support different forms of life and at the same time, the organisms that live there support each other as well.

2. An indicator species is an organism that scientists can observe to see if there are changes in the environment it lives in. They judge the change or the implications based on the absence of the species in the environment (in which they used to be present), the presence of the species, and markers of adaptation due to the change in the ecosystem.

3. Biomagnification is a term used when contaminants that were consumed by the organisms in the lower trophic level are passed on to the next trophic level in higher concentrations. This is why those in the highest trophic levels are affected the most because they get the higher concentration of contaminants. DDT was banned when this phenomena was observed.

4. The greatest decrease in rain forest stability would be due to the cutting of trees. We can disrupt stability by gathering resources like nuts from some trees or when you remove one species of plant for medicine. However, the trees are an essential part of the rain forest because each part or area of the tree support different organisms. By cutting the whole trees off and several of them, you doom the organisms that rely on them as well.

5. As mentioned above, bioaccumulation is often interchanged with biomagnification but they differ in the usage of the terms. Like biomagnification, it talks about the accumulation of contaminants in organisms that ingest or absorb them. But bioaccumulation is a term used in a smaller scale, where it talks about the accumulation of the contimants in the tissues of the organism and not how they are passed on.

How would homeostasis be affected if the cardiac muscle stopped contracting?
vodka [1.7K]

The heart is a muscle, therefore, if the cardiac muscles stopped contracting, the result would be the ceasing of heart function. That would lead to death, as blood wouldn't be pumped throughout the body. Homeostasis would therefore be interrupted.
