Sort the mutations based on whether their effects are harmful, beneficial, or neutral to the organisms that experience them. a m
ExtremeBDS [4]

Answer:

A mutation is generally referred to as certain alternations in the gene whether it may be DNA sequences, which may be beneficial, harmful or of no significance to the mutant gene bearing organisms.

Explanation:

  • A mutation that increases the ability to store moisture in a dry environment is obviously beneficial. Because it prevents dehydration and maintains normal functioning in spite of adverse conditions.
  • A color mutation that decreases a bird's chances of sexual selection is beneficial in the sense that it prevent certain abnormalities in offspring like sexual dimorphism. Also sexual selection often proves to be a threat to the survival of the organisms as per handicap principle.
  • A mutation in non coding region of DNA is harmful, as it is often observed to facilitate expression of wrong proteins at inappropriate places.
  • A mutation in the that does not changes protein synthesis increased white pigmentation on a prey animal in snowy environment as it had prevented adaption of the prey and hence harmful for survival of it.
  • A mutation decreasing plant's height in competition to light, makes them less exposed to sun energy important for photosynthesis and hence it is harmful for the plant.

Countercurrent multiplication involves A) ions leaving ascending limb to make water come out of the descending limb B) water lea
Snowcat [4.5K]

Answer:

The correct option is A

Countercurrent multiplication is the process whereby energy is used to generate an osmotic gradient in which water is reabsorbed from the tubular fluid to produced concentrated urine.

Explanation:

Countercurrent multiplication moves sodium chloride from tubular fluid into interstitial space deep within the kidneys. The concurrent multiplication process build up osmotic gradient interstitial fluid in a single effect. Here, sodium chloride is driven by active transport out of the tubular fluid in the thick ascending limb into the interstitial fluid, which becomes hyperosmotic. This result to water moving passively down its concentration gradient out of the tubular fluid in the descending limb into the interstitial space to a point where it attains a state of equilibrium.

Therefore,the correct option is A, where the ions leaves the ascending limb to make water comes out of descending limb.
