Answer:
<u>3) Uncontrolled cell division occurred as a result of gene mutations</u>
<u />
Explanation:
Spontaneous modifications within the genome may occur during the process of cell division. When copies of the DNA inside the cell are made, these mutations cause errors; and can include small single nucleotide polymorphisms, and large scale additions or deletions across multiple genes.
Some, like somatic mutations, exist only inside vegetative (body) cells, that cannot be passed onto offspring. This is caused by several factors like
- UV radiation,
- chemical mutagens,
- infective agents
UV radiation damages strands of DNA, by causing dimers to form; here, consecutive nucleotide bases covalently bond instead of those on the complementary strand. This conformational change causes errors in DNA proofreading and repair mechanisms where bases are not well-incorporated into the strand- tumors (clumps of uncontrolled cell growth) may form, resulting in melanoma, a type of skin cancer.
Answer:
Warm air is cooling quickly.
Explanation:
Hot air rises and cool air sinks.
Last Friday after dealing with the stressors of daily life, Jane was likely to have <u>increased level of cortisol</u> in her blood stream.
Explanation:
Daily life activities, responsibilities, duties, events all leads to a lot of stress among individuals. This stress affects our body, thoughts, mind, feelings and behavior.
Cortisol is a stress hormone secreted by the adrenal glands by the triggering of adenocorticotropic hormone of the pituitary gland.
Stressors due to daily life activities and other health problems leads to cortisol awakening response and increases the level of cortisol in the blood stream in order to cope up with the increased stress.
Increased cortisol levels causes a number of health issues like anxiety, depression, headache, digestive issues, cardiac problems, sleep disturbance, cognitive impairment etc
Organism is the answer i hope
<span>Since the seminal vesicles produce somewhere in the 60 to 70 percent range of the overall volume of the ejaculate, this would lead to the volume of the fluid being in the 3.6-4.2 ml range. The prostate gland would be responsible for the remainder of the collected volume.</span>
