Answer:
The correct answer is A. Brief stressors lead to changes in cytokine production.
Explanation:
Cytokines form an important group of proteins that act as mediators of communication between living cells. They can exert their action in a paracrine way (between neighboring cells within the same tissue), or endocrine (between cells located in different tissues). The imbalance on the immune system that stressful events exert is an increase in the production of pro-inflammatory cytokines and their associated spectrum of age-related syndromes and diseases. Proinflammatory cytokines are soluble mediators that promote and mediate inflammatory processes, the following stand out: interleukin 1 (IL-1) is involved in the regulation of the immune process and inflammation; interleukin 6 (IL-6) that also serves as a link between the endocrine system and the immune system; and Tumor Necrosis Factor (TNF), which has the ability to destroy certain cell lines and initiate the cascade of pro-inflammatory cytokines and other mediators.
The thyroid gland releases triiodothyronine (T3) and thyroxine (T4). These hormones play an important role in regulation of your weight, energy levels, internal temperature, skin, hair, nail growth, and more. Thyroxine (T4) is produced by the thyroid gland under regulation from the hypothalamus and pituitary gland. T3 is a second thyroid hormone that is produced by the thyroid gland but also in other tissues through deiodination of T4. T3 helps maintain muscle control, brain function and development, and heart and digestive functions.
Hand burning from stove-remove hand away from stove-somatosensory stimulus
Answer:
Question 1 - c. vv
Question 2 - b. Any of the non-sex chromosomes
Question 3 - b. Eukaryotic
Explanation:
Question 1
As explained, the gene for normal wings (V) is a dominant gene while the gene for the vestigial wings (v) is recessive. Dominant genes overpower any recessive genes.
VV - Two dominant genes will produce the dominant trait
Vv - The dominant gene (V) overpowers the recessive gene (v) and produced the dominant trait.
This means that the only way to have a fly with vestigial wings is if the fly has 2 recessive genes. This means that our answer is c. vv
Question 2
An autosome is defined as any of the non-sex chromosomes.
Question 3
Linear chromosomes are a type of chromosome most often found in eukaryotic cells. On the other hand, prokaryotic cells usually have circular chromosomes. This means that our answer is b. eukaryotic
