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.
<span>Ethology is a branch of zoology concerned with the study of animal behavior. Ethologists take a comparative approach, studying behaviors ranging from kinship, cooperation, and parental investment, to conflict, sexual selection, and aggression across a variety of species.</span>
The difference between genomics and proteomics is simple as the names sounds. Genomics is the study of the genes in an organism while Proteomics is the study of the all the proteins in a cell. Proteomics studies are more beneficial because proteins are the functional molecules in cells and represent actual conditions.
This is mitosis: the cell does steps before it splits in two
G1 - synthesis - G2 - M(mitosis) in mitosis is PMAT
Prophase
Metaphase
Anaphase
Telophase
Then the last step is cell division or what its called is cytokinesis
