Epigenetics refers to a special kind of hereditary mechanism. Epigenetic changes do not change the DNA nucleotide sequence, yet

their effect on gene expression can last for several generations. In one surprising study, it was found that the grandsons of men who suffered a famine were less likely to die of cardiovascular disease. The experience of famine made some cardio-protective change in the sperm of those grandfathers that was passed on. What type of change was likely responsible?
A. histone acetylation or DNA methylation
B. Phosphatase levels
C. ubiquitin tagging

<u>Answer:</u>

The type of change that was responsible was “histone acetylation or DNA methylation”.

<u>Explanation:</u>

  • Histone acetylation is the process that involves the epigenetic adjustments that functions in the transcription process while regulating DNA.
  • Histone acetylation or DNA methylation is the major component of the gene regulation while passing from one generation to another.
  • The Acetyl groups are hooked up to lysine’s in histone tails so their charges play a vital role to avoid the histone tail to bind with the other molecules.

The answer to the questions
Aleksandr [31]
The answer that makes the most sense is number one or two. Number 3 and number four both makes no sense in that context. Most of the time an animal will not die or mutate due to a parasite in its body.

What is the answer to this question?"explain two difficulties an ecologist might have in counting a population of migratory bird
dimulka [17.4K]
<span>It may be difficult for ecologists to determine the size of a bird population if that population migrates to different locations throughout the year. During migration, some birds may split off from the group and not return, others may die, and still others may join. Therefore, the bird population will be in constant flux. It is hard to know, when the birds return to their prior location, if the population consists of the same group of birds (in addition to deaths and births) or whether it has grown or shrank through other means. However, to estimate the size, an ecologist can track a migratory flock through several years, counting each year to get a general sense of the population size. Additionally, given one measurement, an ecologist could consider the average lifespan and birth rates of the population to extrapolate the size of the population in subsequent years.</span>
