Answer:

B. 25%

Explanation: If you draw a Punnett square you see that you get TT, Tt, Tt, and tt. Now if T (Hitchhikers thumb) is dominant over t (non hitchhikers thumb) TT, Tt, and Tt are all going to have hitchhikers thumb and only tt won't have hitchhikers thumb. 1 out of 4 is equal to 25%.

Suppose a female began menstruating at age 12 and stopped menstruating at age 55. if she never became pregnant and her menstrual
Arte-miy333 [17]

Answer:

561

Explanation:

This is math so I got you.

This is just going to subtract 12 from 55 since we don't now when during her 12th year of age she started or when during her 55th year f age she ended.

55 - 12 = 43, so about 43 years.  Also not going to account for leap years.  So we are just going to say each year had 365 days.  so 43 years and 365 days per year = 15695 days.

If her cycles were each about 28 days we divide the total number of days by 28 and that tells us about how many cycles there were.

15,695 / 28 = 560.5 which I will round to 561

561 cycles means 561 eggs if my biology knowledge is as accurate as I think it is.

step 2: mRNA moves to cytoplasm, then ribosome
step 3: mRNA goes through ribosome 3 bases at a time
step 4: transfer RNA (tRNA) matches up with the open DNA bases
step 5: tRNA releases the amino acid at the top, which joins the chain of amino acids being produced
