Which of the following statements about vicariance and dispersal is most accurate?

Biology
1 answer:
V125BC [204]3 years ago
7 0

Answer:

Answer is A. Vicariance does not require organisms to disperse.

Explanation:

Vicariance occurs when there is a sudden occurrence barrier , such as geographical area barrier that cause the isolation of species of organisms.

Dispersal involves the movement of the organism while vicariance is the change in environment due to sudden occurrence in the area.

In this case, vicariance  does not involve movement of organisms while dispersal involves movement of organisms.

How do rates of mutation "power" molecular clocks?
stepladder [879]
Molecular clocks use rates of mutation to measure evolutionary time.Mutations add up at a fairly constant rate in the DNA of species that evolved from a common ancestor. The more mutations that happened in each lineage, the greater is the differences between these lineages.

<span>Mature tRNA has an amino acid binding site at one end and the other end interacts with the mRNA by complementary base pairing due to the presence of an anticodon. An anticodon is a three nucleotide sequence which is complementary to the triplet codon of mRNA which specifies a protein for synthesis.</span>

If green plant cells are incubated in the presence of CO2 molecules containing radioactive carbon atoms, the fate of the carbon
stellarik [79]

Answer:

  1. Glycine
  2. Ribulose 1,5-bisphosphate
  3. 3-phosphoglycerate
  4. Glyceraldehyde 3-phosphate.
  5. Glucose
  6. Sucrose

Explanation:

The glycine, among other amino acids, helps to improve chlorophyll production and promotes the process of photosynthesis.  

<u>Calvin cycle</u>

During the carbon fixation phase, a CO² molecule combinate with a ribulose 1,5-bisphosphate to form 6-carbonated molecules, which will divide into two 3-phosphoglycerate molecules.  

During the reduction phase, NADPH donates its electrons to reduce 3-phosphoglycerate molecules, and turn them into glyceraldehyde 3-phosphate.

During the regeneration phase, a glyceraldehyde 3-phosphate molecule leaves the cycle and goes to the cytosol to form glucose. This step can be done when three CO² enter the cycle and produce six glyceraldehyde 3-phosphate molecules. One of them leaves the cycle to form glucose, while the other five are recycled.

<u>Cytosol: </u>

Once in the cytosol, glyceraldehyde 3-phosphate molecules are used to form glucose and fructose. These two molecules are the monosaccharides that form the sucrose.

Once sucrose is formed, it is transported from the photosynthetic tissues to different parts of the plant by the phloem.
