The answer is stroke. This means that formation of plaque in the blood vessels that serve the brain cause thickenning of the inner walls of the vessels. When the plaque ruptures, a blood clot forms and blocks blood passage to a particular region of the brain served by the vessel. This stifles oxygen supply to the respective part of the brain leading to the death of the cells in the region.
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.
The part of the neuron that carries impulses away from the cell body is the axon. Think Axon, Away.
Answer: Mitochondria
Explanation:
Mitochondria are rod-shaped organelles bounded by a double membrane in which the inner membrane is folded and filled with matrix. Mitochondria is present in both plant and animal cells, and serves as the power house where respiration occur and energy is released from the oxidation of simple sugar.
Answer:
A because those are even numbers that are half or close to 100
