Answer:
The correct option is D. A clogging of the arteries resulting from a build-up of plaque composed of fat, cholesterol, and other substances is called atherosclerosis.
Explanation:
Atherosclerosis can be described as a situation in which the arteries become clogged due to the deposition of plaque. The plaque causes the passage for blood to become thinner in the arteries hence seriously affecting the flow of blood in the body.
Other options are false because hypertension is a condition in which blood pressure in the arteries remains high for a long time. Agnosia is a condition in which brain damage occurs and it has nothing to do related to arteries. A condition in which loss of speech occurs is termed as aphasia.
Answer:
b. Many mitochondrial proteins are coded by cellular nuclear DNA.
Explanation:
According to the concept of endosymbiosis, eukaryotic organelles such as mitochondria and chloroplasts arose from symbiotic relationships between larger cells and smaller prokaryotes. These smaller prokaryotes were incorporated and lived within them. According to this concept, mitochondria originated when a larger cell engulfed an aerobic bacteria (most probably the purple bacteria) that lived in it. However, some of the proteins of the mitochondria are encoded by nuclear chromosomes. This dependence of mitochondria on nuclear DNA does not support the concept of endosymbiosis.
Answer: there is no picture lol
Explanation:
Answer:
Norepinephrine also stimulates serotonin release by binding α1-adrenergic receptors located on serotonergic neurons in the raphe. α1-adrenergic receptor subtypes increase inhibition in the olfactory system, suggesting a synaptic mechanism for noradrenergic modulation of olfactory driven behaviors.
The answer is 9 out of 16 offspring or 56.25 percent.
It is known that the in dihybrid cross (a cross between two different traits), the phenotypic ratio between the offspring, which parents are heterozygous, is 9:3:3:1.
R is an allele for round seeds, r is the allele for wrinkled seeds.
Y is the allele for yellow seeds, and y is the allele for green seeds.
It can be assumed the following:
9 - individuals with both dominant traits (RRYY) - plants with round and yellow seeds.
3 - individuals with the first dominant trait and the second recessive trait (RRyy) - plants with round and green seeds.
3 - individuals with the first recessive trait and the first recessive trait (rrYY) - plants with wrinkled and yellow seeds.
<span>1 - individual with both recessive traits (rryy) - plants with wrinkled and green seeds.</span>
