Answer. D
Explanation:
After the messenger RNA (mRNA) is formed, it has to go trough different steps before being translated into proteins, also known as maturation of the mRNA. One of the most important steps is splicing, a process that removes the introns (regions of the sequence that do not codify for any particular amino acid sequence or protein). In other words, the splicing process removes sequences that do not generate any protein, leaving only the exons to be translated into protein. However, the genes (within our DNA) will contain exons and introns; Therefore, the gene sequence will have more kilobases compared to mature mRNA as the introns in this macromolecule have been spliced out.

Answer:
Food insecurity
Explanation:
Food insecurity is a situation that occurs when people do not have adequate reliable access to enough healthy and nourishing food which they require for their growth and development and an active and healthy life. Food insecurity causes famine and hunger. Certain factors such as lack of food, instability, inappropriate utilization and insufficient access over a particular period of time may result in food insecurity.
Answer:
The correct answer is both pumps use proteins to transport substances across the cell membrane.
Explanation:
Sodium potassium pump helps in the active transport or uphill transport of both sodium and potassium across the cell membrane against their concentration gradient.
Whereas Ca2+ATPase or calcium pump itself is a trans membrane or membrane spanning protein which helps in the transport of Ca2+ outside the cell to maintain electrochemical potential of Ca2+ ions.
Answer;
Decreased birthrate
If immigration and emigration numbers remain equal , decreased birthrate could cause a slowed growth rate.
Explanation;
All populations change in size with time . Change in population is dependent of various factors, namely; birthrates, death rates, immigration and emigration.
Therefore; change in population size would be given by the difference of the sum of birth rates and immigration and the sum of death rates and emigration. That is; Change in Population Size = (Births + Immigration) - (Deaths + Emigration). A decreased birth rate with emigration and immigration remaining constant would cause a slowed growth rate.
