Answer:
(B) It is better for the cell if most molecules are prevented from entering.
I hope this helped at all.
<h2>Inbreeding </h2>
Explanation:
Inbreeding is defined as the formation of offspring which results from the mating of two closely related organisms
Inbreeding affects allele frequencies and genotype frequencies in a population in following ways:
- Inbreeding increases homozygosity
which in turn decreases the biological fitness of a population because there are chances that offsprings will be affected by deleterious traits in this case
- Inbreeding itself does not cause evolution, because allele frequencies do not change in the population as a whole
Answer:
The question lacks options, the options are;
A) 4 KJ
B) 122 KJ
C) 30.5 KJ
D) 1600 KJ
The answer is B, 122KJ
Explanation:
Adenosine triphosphate (ATP) is the energy currency of all living cells. It is the usable form of energy by cells for their life functions. Energy in ATP is harnessed via the hydrolysis of one of its phosphate molecules to form Adenosine diphosphate (ADP). The energy (measured in Kilojoules) needed by cells is released in this process.
In this case, a cell uses energy to pump hormones into the bloodstream. According to the question, 4 ATP's were used i.e. 4 ATP were converted to ADP. The hydrolysis of one ATP molecule releases 30.5 KJ/mol of energy needed for cellular work.
Hence, if 4 ATP were utilized by this particular cell, 4 × 30.5 KJ = 122 KJ of energy will be used by the cell to pump hormones.
