It should be every answer except: some traits are passed together from generation to generation
Answer:
explanation below
Explanation:
Leprosy, known as Hansen’s disease, is a chronic infection that is caused by Mycobacterium leprae. This disease damages peripheral nerves and effect areas like skin, yes, muscles and noses. Antibiotics are used to treat the infection between 6 – 12 months. When infected people refuse to follow the treatment schedules given to them by the medical experts, there is usually the development of more antibiotic-resistant M. leprae.
M. leprae, just like tuberculosis, cell walls contain fatty molecules known as mycolic acids, which make the bacteria less susceptible to antibiotics.
Researchers have made remarkable progress in developing drugs such as ethionamide, isoxyl, thiolactomycin, and triclosan that are known to inhibit mycolic acid biosynthesis.
The development of these drugs are part of the tuberculosis drug discovery efforts (in the last one decade) which has been successfully applied to therapeutic targets in the unique mycobacterial wall.
Since morphology and cell wall of M. leprae does not differ remarkably from that of M. tuberculosis, antibiotic developed to inhibit the biosynthesis of mycolic acids would help to treat leprosy
Which of the following species reproduces by internal fertilization?
a) cats
(b) Toads
(c) The fish
(d) alternative b and c
Answer:
(a) Los gatos
Explanation:
Only cats are capable of internal fertilization from the given choices above.
Internal fertilization is the fusion of gametes within an organism. This process occurs during sexual reproduction within the female.
- Toads and fishes exhibit external fertilization.
- External fertilization occurs where the male sperm externally fertilizes the eggs of the female.
- This usually takes place in a moist or wet place especially water bodies. The liquid medium will transport the sperm to the egg.
In cats, the female specie takes in reproductive cells from the male during coitus and it fertilizes the her eggs to produce a zygote.
I think it’s So lipid-soluble molecules do not enter or exit the plasma membrane unassisted
