Answer:
a and b
Explanation:
The growth of adipose tissue in newborns is directly linked to the fact that they do not have proper body temperature control, so fat acts as a thermal insulator in order to maintain a constant temperature, also, breast milk density can also influence baby fat gain.
For the first six months the baby still has a lot of fluid retention and so it may give the impression that he is getting fatter, but after the first six months until the end of the first year, the baby tends to lose this fluid, decreasing on average 10% of body weight.
<u>Girls</u> in adolescence and pre-adolescence have a tendency to gain weight due to the enormous hormonal load they receive at puberty, as well as other factors such as poor diet.
The same does not happen as often in <u>boys</u> because a good part tends to have a "leap" growth in puberty, favoring weight loss. The process of fattening in teenage boys is more associated with sedentary practices and consumption of junk food.
Answer:
I'd go for A since mitosis produces two diploid cells that are identical to each other and its parent cell where meiosis does not.
Explanation:
The answer to you’re question would be catalyst
Answer:
B) decreased chromatin condensation
Explanation:
The addition of acetyl groups to the histone tails results in a less packed state of chromatin. The acetylation of multiple Lys residues in the amino-terminal domains of histones H3 and H4 reduces the affinity of the entire nucleosome for DNA. It occurs since acetylation reduces the total positive charge present on histone proteins. Histone proteins are positively charged and pack the negatively charged DNA around them. Therefore, increased acetylation results in decreased condensation of chromatin. The loosely packed DNA is accessible by RNA polymerase and transcription factors for gene expression.
