Answer:
SAM and HPA
Explanation:
The physiology of stress has two components. One in which is a fast response meditated by the SAM axis, and one which is a slow response meditated by the HPA axis.
Answer:
crossing over, process in genetics by which the two chromosomes of a homologous pair exchange equal segments with each other. Crossing over occurs in the first division of meiosis . At that stage each chromosome has replicated into two strands called sister chromatids. The two homologous chromosomes of a pair synapse, or come together. While the chromosomes are synapsed, breaks occur at corresponding points in two of the non-sister chromatids, i.e., in one chromatid of each chromosome. Since the chromosomes are homologous, breaks at corresponding points mean that the segments that are broken off contain corresponding genes , i.e., alleles. The broken sections are then exchanged between the chromosomes to form complete new units, and each new recombined chromosome of the pair can go to a different daughter sex cell. Crossing over results in recombination of genes found on the same chromosome, called linked genes, that would otherwise always be transmitted together. Because the frequency of crossing over between any two linked genes is proportional to the chromosomal distance between them, crossing over frequencies are used to construct genetic, or linkage, maps of genes on chromosomes. Mutations , temperature changes, and radiation all affect crossing over frequency. Under the microscope, a crossover has the appearance of an X and is called a chiasma.
Explanation:
Answer:
b.) earthworms and ants
Explanation:
Pedogenesis is also knowns as Soil formation. This is the process of soil formation due to the regulated effects of place, environment, and history.
The rock from which soil is formed is called the parent rock (bedrock).
The most important life form during the beginning of pedogenesis are earthworm and ants because their burrowing nature in the soil helps in the breakdown of the bedrock. This aids the process of soil formation.
Answer:
A biotechnology researcher might work on creating biofuels (First option).
Explanation:
A biotechnology researcher, or <u>biotechnologist</u>, has the ability and tools to use organic matter and living beings for the manufacture of products, applying the technology.
A biotechnologist can work in the agricultural industry, pharmaceuticals, or developing products for environmental protection, such as biofuels.
Biotechnology is a <u>science applied to the manufacture of new and sustainable products, through molecular and biochemical research of organic material, plants and animals</u>, for this purpose.
The other options are not correct because:
<em> 2. The </em><u><em>design new hospital beds</em></u><em> depends on hospital engineering.

<em> 3. </em><u><em>Testing blood for diseases</em></u><em> are performed by a bioanalyst or laboratory technician.
</em>
<em> 4. </em><u><em>Using MRI machines</em></u><em> is performed by a radiologist or radiology technician.</em>
