The answer is to decrease the secretion of substances from the pituitary gland that cause growth. 

Gigantism is condition characterized by excessive growth. It is the consequence of over-production of growth hormone (somatotropin) in the pituitary gland. So, the effect of the drug used on patients diagnosed with gigantism must be to decrease the secretion of growth hormone in the pituitary gland. That way, there will be less of growth hormone, and the excessive growth can be stopped.

Inga [223]

Complete question:

In the 1890s, Northern elephant seals were hunted almost to extinction. An unknown population of less than one hundred animals managed to survive on the tiny island of Guadalupe off of Mexico. The current population of over 100,000 is thought to be derived from that tiny remnant population. Compared to the Southern elephant seals (which did not experience such a bottleneck), the Northern elephant seals likely have -------- (Lower - Higher) genetic diversity and -------- (Lower - Higher) levels of genetic diseases.

Answer:

In the 1890s, Northern elephant seals were hunted almost to extinction. An unknown population of less than one hundred animals managed to survive on the tiny island of Guadalupe off of Mexico. The current population of over 100,000 is thought to be derived from that tiny remnant population. Compared to the Southern elephant seals (which did not experience such a bottleneck), the Northern elephant seals likely have Lower genetic diversity and Higher levels of genetic diseases.

Explanation:

Genetic drift is the random change that occurs in the allelic frequency of a population through generations. The magnitude of this change is inversely related to the size of the original population. These changes produced by genetic drift accumulate in time. Eventually, some alleles get lost, while some others might set. Genetic drift affects a population and reduces its size dramatically due to a disaster or pressure-bottleneck effect- or because of a population split -founder effect-.

In the exposed example, extensive hunting acted as a pressure that reduced the number of Northern elephant seals to fewer than 100. This population experienced one or many generations of small size since these animals were affected by hunting. As the survivors did not have the whole genetic pool of the original population,  the population size might have recovered to a current population size of 1000,000 individuals, but <u>the genetic pool might have not</u>. When the small population increases in size, it will have a genetically different composition from the original one. In these situations, there is a<u> reduced genetic variability</u>, with a possibility of developing a peculiar allelic component. If the survivors in the population carried or developed a mutation, probably this mutation passed from generation to generation. It will involve more individuals each time and<u> increase the probability of developing a genetic disease</u>.

What embyonic germ layer gives rise to muscle?
navik [9.2K]

The mesoderm is one of the embryonic layers together with the ectoderm and endoderm. The germ layer that gives rise to muscle is the <u>mesoderm</u>.

<h3>What is the mesoderm?</h3>

Three embryonic layers are present in the blastoderm after segmentation. One of them is the <u>mesoderm</u>, which is located between the ectoderm and the endoderm.

Different tissues and cells are formed from the mesoderm, such as muscular, skeletal, circulatory, and connective tissues.

The correct anwer is mesoderm. The embyonic germ layer that gives rise to muscle is the mesoderm.

The distance from point A to point B is known as the A) amplitude. B) frequency. C) pitch. D) wavelength.
wlad13 [49]

The answer is A) Amplitude

Explanation: Point A to B represents the amplitude. As amplitude, or wave height, of a sound wave changes, the volume of the sound changes.
