Answer:
In the result of meiosis, testes produce 4 small mature sperm while ovaries produce 1 large egg cell.
Explanation:
Meiosis produces gametes (sex cells). Sex cells are eggs in females and sperm in males.
In the female, ovaries produce four haploids (3 polar bodies and 1 immature egg) under meiotic division. Polar bodies die because of the unequal division of cytoplasm. The immature egg matures into a large ovum/egg every 28 days during the menstrual cycle that is able to fertilize.
In the male, meiosis occurs in testes that produce 4 spermatids that mature into 4 small sperms. Testes produce several hundred million sperms every day under meiosis. These sperms are able to fertilize.
Nevertheless, if we want to compare their numbers based on meiotic division, we would say that they will be in the same ratio (1:1) at the end of each meiosis cycle for males and females.
Answer:
*furiously writes F until there was a true statement*
8. F (isotonic is where water diffuses in and out of the cell in equal rates to which it could move back and forth)
D.F (hypertonic solution is where the water will diffuse out from the cell as hypertonic solution's concentration is higher than the concentration of solute within the cell)
c.F (" but the water should be diffuse into the cell)
d.F (osmosis only related to water)
e.T (carrier proteins has the ability—it changes its shape to allow the molecules to pass through to the other side of the plasma membrane)
f. F (cuz facilitated diffusion issa passive transport and a passive transport must be going down the gradient aka from high to lower concentration)
Answer:
B) Viruses are killing some of his B cells and becoming incorporated into the genomes of others.
Explanation:
Epstein-Barr virus causes infectious mononucleosis by following mechanism.
1) Epstein-Barr virus attaches to and infects epithelium of the throat where it replicates and causes pharyngitis.
2) Virions enter the lymphoid vessels and are carried to the lymph nodes. Some virions escape the lymphnode trap and are carried to the bloodstream.
3) Virions attach specifically to B lymphocytes and infect them, producing either latent infection or productive infection.
4)The infected B lymphocytes actively replicate and differentiate into cells producing random immunoglobulins.
5)T cells respond to infection and destroy the lymphocytes replicating EBV vitus.
6) Latently infected B lymphocytes become immortal. They are not attacked by T cells.
Answer:
How do the Linnaean scientific names compare to the names developed by John Ray?
Linnaean names tend to be longer
Explanation:
John Ray defined the word specie before linnaeus started his own binomial and trinomial naming of organism. John Ray definition was at specie level while Carls Linnaeus used both generic and species e.g <em>Australopeticcus africanus africanus </em>which is the first man to live
