Answer:
A) Apoptosis, or the automatic death of a cell.
Explanation:
This is because the question asks what mechanism ensures/confirms the purpose of the mechanism where a cell prevents damaged cells from continuing to divide if it suffers DNA damage. In other words, how do we know the intent of the cell preventing damaged cells from continuing to divide is to prevent DNA damage? Well, it's apoptosis, which can be triggered if there is too much DNA damage.
Answer:
homologous traits
Explanation:
Cladistics is defined as a method of analyzing the evolutionary relationships between groups of living beings, aiming to elucidate their genealogy.
Although its use among researchers exceeds 50 years, it is only in the last 20 years that its use has become popular, almost worldwide. Researchers often use homologous traits to use cladistics to search for research completion. The cladistics is based on the fundamental principle that the classification of organisms must be made according to their evolutionary relationships and that the way to elucidate these relationships is by analyzing what is referred to as ancestral characters, or "primitive", and derived, or "evolved" characters.
These lifestyle modifications can also help prevent obesity if you are overweight or otherwise at risk. Achieving and maintaining a healthy weight through diet and exercise can also help manage or reverse some of the serious conditions associated with obesity, such as hypertension and type 2 diabetes.
Answer:
(C) Enzyme does not need to contact with substrate to assume its active form.
Explanation:
a) The activity of an enzyme can be increased upto certain temperature known as optimum temperature after that tepmerature will damage the enzyme.
b) The number of substrate molecule converted by one molecule of enzyme in one second is called its turn over rate, which may varry from 0.5-600000.
C) Enzymes does not need to contact with substrate to assume its active form. They just accelerate the reaction by lowering the activation energy. Enzyme binds to substrate through active stite and both changes structures slightly to best fit.(Induce fit model)
- Enzyme + Sbstrate → enzyme substrate complex→ Enzyme + Product
D) Some enzymes are inactive known as apoenzyme and they need a non-protein part such as coenzyme or cofactor to become active which is known as holoenzyme.
