Human growth hormone (GH) is a substance that controls your body's growth. GH is made by the pituitary gland, located at the base of the brain. GH helps children grow taller (also called linear growth), increases muscle mass, and decreases body fat.
Answer:
The climate change may turn diseases spread in different areas of the Globe.
Explanation:
Climate change is producing the environment to evolve constantly. We may see rising temperatures across the Globe and with it some changes on rainfall as well. Those features will dramatically change the whole environment and could possibly turn habitats, that were in the past not associated with disease vector insects, into places like the northeastern from United States and thus, mosquistoes like the the vector of malaria can be a possible disease to hit developed countries.
Hi!
The ancestral finch founded a new population on one of the Hawaiian Islands. Due to the founder effect , allele frequencies of the first small population on one of the islands could have differed from their continental goldfinch-like ancestors. The process of natural selection resulted in adaptation and evolution of the island population into a new species over time. Some of the birds crossed to some of the other islands where they were geographically isolated and evolved into more species occupying different niches.
In terms of population genetics, founder effect is when there is a loss of genetic diversity as a result of the establishment of a new population by a relatively few individuals. Following such an establishment, natural selection is the process which results in the genes of the fittest individuals of the population being selected over generations. This process ultimately results in evolution, and over time may give rise to new species. Geographical isolation is the physical separation of a population from another owing to geographical changes in the terrain or area. If two populations of the same species are geographically isolated, there is a great chance over time they may evolve into two different species.
Hope this helps!

Answer:
luteinizing hormone (LH) is mainly used to induce ovulation.
Explanation:
Ovulation refers to the release of an egg.During menstruation ovarian follicle discharges an egg.The egg is also known as an ovum, oocyte, or female gamete. It is only released on reaching maturity.
Ovulation induction uses hormonal therapy to stimulate egg development and release egg or ovulate.
By increasing the production of follicle stimulating hormone (FSH) by the pituitary gland, follicles are stimulated and hence egg growth is seen.
A surge in the Luteinizing hormone (LH) causes the egg to release or ovulate. Luteinizing hormone (LH) is produced and released in the anterior pituitary gland. This hormone is a gonadotrophic hormone and plays an important role in controlling the function of ovaries in females and testes in males.
In women, the hormone stimulates the ovaries to produce oestradiol. Two weeks into a woman's cycle, a surge in luteinizing hormone causes the ovaries to release an egg during ovulation. If fertilization occurs, luteinizing hormone will stimulate the corpus luteum, which produces progesterone to sustain the pregnancy.
