1.Because if this system was not functional the toxins would build up in the body.

2.Fiber is made out of cellulose. Our body doesn't synthesize an enzyme that digests cellulose(cellulase) that's why we can't metabolize it. fiber is good because it reaches the colon undigested and helps the intestinal fauna and can even prevent colon cancer

3.If the organism will stop reproducing they will eventually die and there would be no offspring left so life will die out.

4.You would consume a lot of calcium. For example milk and lactates.

5.The stem will grow towards the sun(phototropism) and the root will go towards gravity(geotropism) and minerals(chemotropism)

Glycolysis
dolphi86 [110]

Answer:

E) can usually make enough ATP for skeletal muscle function

Explanation:

Glycolysis is the main process by which cells obtain energy. During glycolysis, glucose is fully oxidized to obtain ATP, this is the 'fuel' for cellular function. Glycolysis is oxygen dependant, meaning that in order to successfully complete the process, enough oxygen must be available.

There are a few exceptions in which glycolysis is unable to provide enough ATP, an example is strenuous exercise. In this case the speed of oxygen consumption is very high, therefore at some point the oxygen intake is not enough. There are several mechanisms that regulate the production of ATP. In case of strenuous exercise, different process are activated to supply the cell with the necessary energy to keep on functioning.

Among the latter mentioned processes, there is anaerobic production of the oxidation of lactate, that does not require oxygen. Other example is the usage of creatine phosphate to obtain energy. Therefore, muscular cells have many ways of obtaining energy, but this secondary mechanisms are only activated in specific situations.

Ivan

Answer:

1- A species can migrate over long distances because they have metabolisms suitable for that, adaptation mechanisms to withstand different adversities. They usually do it to be able to reproduce in ideal climaxes or feed on certain living things or plant species.

2-The existence of oil fields, or oil towers for the manufacture of fuel.

3-Implement electric cars or batteries that do not depend on fuels such as diesel, naphtha.

Explanation:

In this exercise it is good to highlight that during the migration of animals of different species their numbers decreased both to reach the territory to which they migrate and by human intervention in nature in a harmful way.
