Answer:
Convergent evolution
Explanation:
Convergent evolution is a type of evolution of similar features and/or structures between organisms that are not phylogenetically related. This type of evolution is known to create analogous structures/organs that exhibit similar or the same functions but were not present in the last common ancestor of these taxa. An example of analogous structures (and therefore also of convergent evolution) are the wings of bats and of insects (e.g., butterflies). Conversely, divergent evolution is a type of evolution where species phylogenetically related, i.e., species that share a common ancestor, evolve and accumulate differences over time.

Explanation:
Trepanation is used to treat health problems associated with intracranial diseases, epileptic seizures, migraines and mental disorders by relieving pressure.
Trisomy 21, as illustrated by the karyotype, is caused by nondisjunction. This occurs when chromosomes do not separate properly during meiosis.
Answer is D) nondisjunction
<span>The propositions are:
a. forms glucose from </span><span>noncarbohydrates
b. does all of these
c. destroys damaged red blood cells
d. stores vitamin D
e. forms urea
The right answer is: B. </span>does all of these
*The liver plays a role in the metabolism of carbohydrates:- gluconeogenesis (manufacture of a new glucose molecule from a non-carbohydrate molecule);- glycogenolysis (release of glucose from glycogen) under the effect of glucagon;- gluconeogenesis (storage of glucose in the form of glycogen) under the effect of insulin
*It stores fat-soluble vitamins (A, D, K and E) and glycogen.*It converts ammonia to urea (detoxification)<span>*It recycles substances from the senescent red blood cells.</span>
