The part of the cell membrane that acts as a barrier are the Hydrophobic tails!
Answer:
D
Explanation:
Because water vapour is a gas and evaporation is the process of turning a liquid into a gas so the water which is the liquid turns into water vapour the gas
No muscle contraction will be observed.
<h3>What is the effect of calcium concentration on muscle contraction?</h3>
The concentration of calcium ions in the muscle cells help in contraction and relaxation of muscles fibers.
Release of calcium ions initiate muscle contraction.
Therefore, there will be no contraction of muscle if calcium ions are not transported out from the sarcoplasm.

Answer:
d
Explanation:
<em>The correct answer would be increasing heart rate to compensate for low cardiac output.</em>
The negative feedback loop is the mechanism that is utilized in the maintenance of homeostasis. They work by opposing the processes that bring about a deviation away from setpoints, that is, the normal range of operation of physiological processes in the body.
<u>For example, when the heart rate goes below the setpoint, the negative feedback loop swings into action through the sensor, the control center, and the effector to return the heart rate to the normal operating range.</u>
Correct option: d
The mutation will occur often in offspring and leads to development of genetic variability in the gene pool.
Answer: C
Explanation:
Mutation refers to the process which causes disturbances in the normal DNA pattern.
When such phenomenon occurs over many generations, it will become a common process in offspring and increase the chance of difference in variability in the genetic makeup as well as the gene pool.
It is because, the first stage of mutation appears tedious to the organism.
As it gets transferred from one generation to another generation, the species due to its capability identifies certain ways and exhibit genetic variability due to the mutation.
By this way the mutation will become more common in offspring as their parent have mated in the presence of mutation.
