Answer:These are normal physiological processes that take place inorder to control and facilitate the development and maturation of the male sexual organs and characteristics.
Explanation: Male sexual development occurs between the ages of 10 and 14.
The anterior lobe of the pituitary gland secretes luteinising hormone which further stimulates the interstitial cells of the testes to increase the production of the hormone testosterone.
Under the influence of this hormone testosterone, sexual development and other characteristic changes take place.
The posterior lobe of the pituitary gland secretes growth hormone which helps in the growth of muscles and bones and a marked increase in height and weight.
The anterior lobe of the pituitary gland secretes testosterone which enlarges the larynx and deepens the voice.
Androgen and testosterone also produced by the anterior lobe of the pituitary gland causes growth of hair on the face ,axillae, chest, abdomen and pubis region.
From the anterior lobe of the pituitary gland, Dihydrotestosterone which has a high Androgenic action triggers the enlargement of the penis, scrotum and prostate gland.
The follicle stimulating hormone secreted by the adenohypophysis of the anterior lobe of the pituitary gland stimulates the maturation of the seminiferous tubules and production of spermatozoa.
Answer:
Mutated DNA affects proteins during translation which can cause different proteins to be created
Explanation:
The process of protein-synthesis is when mRNA is translated into different proteins, which takes place in the ribosome. Mutated DNA can cause something known as a "frameshift mutation" where the codons are either inserted, duplicated, and or deleted. The mutation in the mRNA will cause the codons to be misarrageded effectively causing a different protein to be created! We know this through our codon chart, which can be searched for online.
I recommend looking more into Protein Synthesis if you have further questions, I hope this answer helped!
Gender is a cultural construct and perceptions of men and women differ from culture to culture or even during different periods even in a single culture or society.
Answer:
Melatonin is released by the pineal gland, that is hormones or neurotransmitter which is related to the sleep. It is influence the sleep wake cycle. Where as melanin is pigment that naturally colors skin or the hair. More the melanin more the darker the skin or hair.
Melatonin regulates changing in pigmentation by association of melanin into the melanocytes within the skin, leads to the skin to color change. This relation is is also accountable for the yellowish skin color in elderly people and people with insomnia.
Answer:
The best answer choice from the list, to respond to the question: Antibiotic treatment of E. coli is discouraged unless necessary due to concern over:___, would be, E: all of the above.
Explanation:
E. Coli, is the general name used for a group of bacteria that are usually harmless and make a really important part of the human GI tract. In fact, without their presence, that of E.Coli, and other bacteria that make part of the normal flora of the intenstines, digestion of certain foods, and the production of certain vitamins and minerals, would not be possible. Also, they are meant to help contain other bacteria, that are known as pathogenic and cause disease. However, when E. Coli is taken out of its environment in the feces, and especially certain groups, can become serious pathogens that cause diarrhea, and other things. However, it has become almost a trend to treat E. Coli infections with antibiotics and the problem that has ensued, has been manyfold. The first issue has been with resistance. Now we are facing superbugs, especially of the E. Coli variety, that do not respond to common treatments, because antibiotics were used all the time. Second, some strains of E. Coli, will not respond to the same antibiotics, and some, could be treated with simply measures such as diet, rest and hydration. There is also knowledge that since antibiotics are not specific, they will also kill other bacteria that are part of the normal flora of the GI tract, and finally, there is evidence that constant exposure to antibiotics will start having effects on the normal lining of the GI tract. This is why the answer is E.
