The answer is <span>The diploid chromosome number represents two sets of chromosomes, one from each parent, so it is always an even number.
Mentioned organisms are diploid (2n) and they have 2 sets of chromosomes in their somatic cells. However, their gametes (egg cells and sperms) are haploid (n) and have only 1 set of chromosomes.
After fertilization, a haploid egg cell from a mother and a haploid sperm from a father fuse and form diploid zygote:
n + n = 2n
Nevermind if n is odd or even number, 2n will always be even.</span>
Greenhouse gases are those thought to contribute to the greenhouse effect, an overall warming of the Earth as atmospheric gases trap electromagnetic radiation from the sun that would otherwise have been reflected back out into space.
Noteworthy greenhouse gases are methane, nitrous oxide, carbon dioxide, hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6). These gases are thought to affect the climate directly and indirectly, even though they constitute only a small fraction of the blanket of gases that make up the atmosphere.
Currently, the composition of the atmosphere is mostly nitrogen and oxygen, with just 0.033 percent carbon dioxide and all other gases accounting for even less.
Answer:
A. Renin levels increase with poor kidney perfusion
D. Nephrotoxic drugs are a cause of intrarenal failure.
Explanation:
Renin is produced in the kidney for angiotensin aldosterone hormonal system and it is helpful in maintaining the blood pressure and other metabolic activities. However when the renin level is high then it means the kidney has a perfusion issue .
Nephrons are kidney cells. When a drug which is toxic to them gets into the body system then it affects the kidney and may cause kidney failure.
The answer is convergent boundary. This happens at subduction zones which are a type of convergent boundary.
