Answer:

B

Explanation:

replication is just to attempt to ensure that the daughter cells have the full set of DNA (genome) as their parents did as well

The answer is b. because you wouldn't want a daughter cell that didn't have <em>all </em>necessary to be a complete cell, and this could be messed up if the DNA didn't replicate prior to cell division

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.

The type of RNA that delivers amino acids to the ribosome during protein synthesis is tRNA.a) trueb) false
DENIUS [597]

Answer:

A). True

Explanation:

tRNA, which means transfer RNA is one of the three types of RNA known in nature. The tRNA is found in the ribosome, where it plays a pivotal role in protein synthesis (translation). Transfer RNA is the RNA responsible for reading the nucleotides in the mRNA codon and carrying the amino acid that corresponds those codons to the ribosome.

The tRNA has a 3-dimensional structure that allows it to carry anticodon that reads codon and also carry amino acids on opposite ends. Hence, according to this question, tRNA is a type of RNA that delivers amino acids to the ribosome during protein synthesis.

What would happen if your body wasn't in homeostasis
Marysya12 [62]

When homeostasis is not maintained, the body cannot function properly and illness may ensure. Homeostasis is the process in which the body's overall internal environment is kept constant in response to any external environmental changes. This involves maintaining stability in different body systems.
