A high biodiversity tally may indicate that some of its organisms may be able to survive drastic environmental changes. If there weren't at least a few organisms that contribute to biodiversity, most of the biotic Earth would be gone by now.
For example, woolly mammoths were unable to adapt to the up-and-coming warmth of the poles. Because they lacked biodiversity among their species, all of them died out and weren't able to adapt to the heat.
I hope I helped!
The major contribution made by Avery, MacLeod, and McCarty was 'transformation of nonvirulent cells with a DNA extract was blocked only if DNase was added'. This observation supported the idea that the transforming agent in Griffith's experiment was DNA.
The Avery–MacLeod–McCarty experiment showed that DNA was the transforming agent observed in Griffith's experiment.
Griffith's experiment (1928) suggested that bacteria were capable of transferring genetic information (DNA) by a process of horizontal gene transfer called transformation.
While the bacteria were killed by heat, Frederick Griffith observed that the DNA had was taken up by II-R strain bacteria via transformation.
Avery–MacLeod–McCarty experiment observed that protease enzymes did not destroy the transforming agent (but DNAse destroyed this transforming principle), thereby suggesting that the transforming agent in Griffith's experiment was bacterial DNA.

This is an example of negative feedback.
After a big meal, glucose levels in the bloodstream increases. The body recognises this change and goes through homeostasis, or the regulation of bodily state or internal environment.
The pancreas secretes insulin, which then binds to insulin receptors. This will result in the uptake of excess glucose from the bloodstream into cells and converted into glycogen to be stored in cells as energy storage molecules.
Since there is the counter effect of body (i.e. when blood-glucose concentration increases, the body sends a signal to decrease the blood-glucose concentration, this is called a negative feedback (instead of a positive feedback, which occurs if for e.g. the body signals cells to increase blood-glucose concentration even after blood-glucose concentration increased after a heavy meal).
Hope this helps! :)
The structure is calcium ions.
Answer:
Enzyme catalase is affected by high temperatures
Explanation:
Enzymes are organic catalysts which are protein in nature therefore they are sensitive to changes in temperature. Most enzymes have an optimum range of temperature between 35-40°c.
As temperature is increased, the optimum temperature is reached where the rate of reaction is maximum. When beef liver is boiled, hydrogen peroxide is not broken down because higher temperatures denature enzymes making them non effective.
