The correct answer is A. the change in pH affects the shape and function of the enzyme. It can only function properly in its optimal pH range.
Enzymes are protein molecules and they have a specific shape, which is altered by temperatures and pH that are not within the enzyme's range of operation. This is because the temperature and pH alter the enzyme's structure, which means the shape of its active site is changed and its substrate is not able to fit inside the active site of the enzyme molecule.
Cells that are thick in the middle and tapered towards the end are called fusiform cells
<h3>What are fusiform cells?</h3>
Fusiform cells are those cells that has a spindle-like structure which means that it is thinner at the extremes and larger at the center.
A typical example of fusiform cell are the cells of the dorsal cochlear nucleus (DCN).
Therefore, cells that are thick in the middle and tapered towards the end are called fusiform cells

Answer: Faster-evolving gene sequences provide better data for comparisons among close relatives, whereas very slowly evolving sequences work best for distantly related tax.
The answer is: It spins a sample to separate based on density.
Answer:
A, D & E
Explanation: All ATPs are not spent at the same time, and futhermore, they are constantly replaced by the continuous process of cellular respiration that captures the chemical energy in the glucose molecules and stores them in ATP. During the release of this energy to power the biochemical reactions, much of it is lost as heat energy and this is why living organisms are always warm.
