Answer:
mRNAs enable the cell to express only the genes it wants, not the entire DNA genome. These mRNAs exit the nucleus so they can be then translated in the cytosol. ... Varying mRNA creation (transcription), lifespan etc. also allows the cells to fine tune better how much of and when they want to produce a protein.
Explanation:
Calcium is one substance that is secreted elsewhere but not in the proximal convoluted tubule.
<h3>Renal reabsorption and secretion</h3>
Renal reabsorption is defined as the movement of water and specific solutes from the renal tubule back into the plasma.
Renal secretion is defined as the process by which waste ions and hydrogen ions pass from the renal capillaries into the renal tubule to be excreted into the urine.
At the proximal convoluted tubule, calcium is reabsorbed but not secreted. Therefore, Calcium is one substance that is secreted elsewhere but not in the proximal convoluted tubule.

Answer:
C. K- Strategy
Explanation:
this type of strategy involves greater investment from parents into their offspring.
Non-random mating is assortative mating. It is a pattern and form of sexual selection in which individuals with similar phenotypes mate with one another more frequently than would be expected under a random mating pattern. non-random mating can act as an ancillary process for natural selection to cause evolution to occur. It’s also bad for evolution because any departure from random mating upsets the equilibrium distribution of genotypes in a population. Recombination is a process by which pieces of DNA are broken and recombined to produce new combinations of alleles. recombination is important to somatic cells in eukaryotes because it can be used to help repair broken DNA. recombination by itself does not cause evolution to occur. Rather, it is a contributing mechanism that works with natural selection by creating combinations of genes that nature selects for or against. Non-random mating affects the evolution more than recombination
Explanation:
Vestigiality is the retention during the process of evolution of genetically determined structures or attributes that have lost some or all of the ancestral function in a given species. Assessment of the vestigiality must generally rely on comparison with homologous features in related species.
