Answer:

1. d. changes in the methylation patterns of <em>loci</em> involved in growth and metabolic disease

2. b. differences in the expression of metabolic genes

d. changes in histone acetylation patterns

Explanation:

Epigenetics refers to the study of heritable changes in gene expression which are not dependent on DNA sequence. Epigenetic mechanisms involve DNA methylation, histone modifications (acetylation, methylation, phosphorylation, etc) and regulatory non-coding RNA (ncRNA) pathways. These epigenetic mechanisms work together and mutually reinforce each other in order to modulate gene expression (either by activating or suppressing gene expression). In consequence, transcriptome data (e.g., genes differentially expressed in particular tissues/cells or stages of development) is an important piece of evidence indicating the existence of epigenetic modulation.

Which type of protein would more likely be able to function as a channel through the plasma membrane
Ivahew [28]

Inga [223]

Population density refers to the determination of population in a unit area or unit volume. It is generally applicable to the living species, and majorly to the humans. It is an essential geographical term and its a quantity of type number density.  

In the given case, it can be seen that New Zealand exhibits a smaller population in comparison to Australia, but it has a greater population density as it encompasses a much smaller region.  

On the other hand, the population of Australia is about five times more than New Zealand, but Australia covers about 30 times more area in comparison to what New Zealand covers.

You will research major earthquakes and pick one to answer the following questions:
levacccp [35]
Research major earthquakes on google, or another website. I would go with question 1, Where is your earthquake? I would do the Haiti earthquake where the earthquake is in Haiti. Do more research on Google, because I cannot provide you with a link to an article because Brainly will not allow me to do so. Just research "major earthquakes" in Google and you will be good to go. Hope this helped!
