in humans, the allele for hemophilia, h, is recessive. which is true of a woman with the genotype xhxh? a. the woman and all of her children are hemophiliacs. b. all of her sons will inherit the allele for hemophilia. c. she is a carrier of hemophilia but does not have the condition.

Answers

Answer 1

Answer: The answer is b. all of her sons will inherit the allele for hemophilia.

Hemophilia is X-linked recessive disorder. It is known that there are two X chromosomes (one from a mother and one from a father) in females and one X chromosome (from the mother) and one Y chromosomes (from the father) in males. In females, X-linked recessive disorder has the same pattern of inheritance as an autosomal recessive disorder.
So, if xh is recessive and xH is dominant allele, a mother which has xhxh genotype has the condition (so, c is not the right answer). Further, if a father has no condition, thus his genotype is xHy, their daughters will be carriers but without the condition (so, the choice a could be right only if we know that the father has hemophilia too (xhy). Therefore, since the mother (xhxh) will give her x chromosome to her sons, they will all inherit the allele for hemophilia, and choice b. is the right answer.

Scientist from different fields work together to continually modify the chemical composition of antibiotic medicines this is to keep up with adaptive abilities of the pathogen antibiotics are intended to treat. antibiotics inhibit the formation of membranes in certain prokaryotes which of the following would most likely be treated with antibiotics ?A. body cells

B. foreign pathogens

C. inherited factors

D. cells that carry mutations

Explain your answer

Answers

Among the following, the most likely to be treated with antibiotics are
B. foreign pathogens
Foreign pathogens are prokaryotes which are susceptible to antibiotics. Body cells, mutated cells, and inherited factors are immune from antibiotics.

Answer:

The correct answer would be a B. foreign pathogen.

Antibiotics refer to the group of drugs which inhibit the growth of pathogens such as bacteria.

They are mainly designed to treat bacterial infections. For other pathogens such as a virus, fungi et cetera different classes of drugs are used such as anti-viral (for viruses), anti-fungal (for fungal infection) et cetera.

The mechanism of action of antibiotics may include:

Inhibition of synthesis of cell wall
Inhibition of synthesis of proteins
Inhibition of synthesis of nucleic acid
Cell membrane alterations
Inhibition of metabolite activity

Common example may include penicillin and derivatives.

Charles Darwin did poorly in school as a young boy. How did his poor performance belie his genius?

Answers

Charles Darwin always had a taste for natural history as a kid, as far back as eight, in spite of how he performed in school. When he was a young adult, he got an apprentice ship as a doctor from his father who was also a doctor. This gave him experience with the anatomy of the human body. When being a doctor started to bore him, he learned taxidermy, exposing him to the anatomy of wild animals. Later he joined the Plinian Society which was a student natural history group that often debated and questioned the current topics and views of the subject in that time. Not too mention the many natural historians and evolutionists who also inspired him, one of which was his own grandfather,that gave him the support he needed. I guess that even though his normal school curriculum did not interest him, his self determination was enough to keep him grounded to his interests, proving that sometimes a great education doesn't always make you a genius. (idk :) Charles Darwin was smart in his own ways.
