Answer:

The correct answer is E-processing of exons in mRNA that results in a single gene coding for multiple proteins.

Explanation

Splicing is the process where introns are cut out of the mRNA so only the coding parts for proteins. In this way, genes can code for many proteins, depending on how the amino-acids are arranged.

The concentration of nitrates is often higher in
Phoenix [80]

Answer:

(2) diffusion

Explanation:

Diffusion is a process in which molecules moves from a region of higher concentration to the region of lower concentration. In this condition, plant roots contain high concentration of nitrates than soil so nitrates moves from roots through semi-permeable to the soil by the action of diffusion until the concentration is uniform or equilibrium.

Moderate amounts of alcohol _____. improve the body’s utilization of insulin and blood glucose
xxMikexx [17]

Moderate amounts of alcohol improve the body’s utilization of insulin and blood glucose. is true

  • Frequent heavy drinkers can deplete their energy reserves in a matter of hours.
  • Overindulging in alcohol over time can lessen insulin's overall efficiency.
  • As a result, blood sugar levels are elevated. However, many persons with alcoholic liver disease also have diabetes or glucose intolerance.
  • A lower risk of type 2 diabetes is associated with moderate alcohol usage, as opposed to abstinence and heavy drinking.
  • Despite the fact that both males and women's risks are decreased with moderate alcohol use, the associations between the two may be different.
  • Alcohol intake and type 2 diabetes may be linked, and this connection may be explained by adiponectin's actions, enhanced insulin sensitivity, or anti-inflammatory properties.

Mendel did experiments in which he kept track of the inheritance of seed texture (wrinkled or smooth). First he created true-bre
sveticcg [70]

Answer:

smooth was dominant over that for wrinkled

Explanation:

In complete dominance, a gene may have two different variants or 'alleles', dominant and recessive. A dominant allele is a gene variant that is able to produce a certain phenotype, even in the presence of other alleles, while a recessive allele is a gene variant that is masked by the dominant allele in heterozygous individuals (i.e., individuals that inherited different alleles from each parent). By crossing smooth and wrinkled pea plants, Mendel observed the offspring (F1) were smooth rather than mixed, indicating one type of seed texture was dominant over the other. Subsequently, Mendel observed that alleles for different traits (e.g., seed texture and seed color) assorted independently during meiosis.
