Biology

Option A, geographic poles are defined by Earth's rotation, is the correct answer.

The rotation of the earth is its revolution around its own shaft. The direction of Earth's rotation is eastward. The North Pole of the Earth is the spot in the Northern Hemisphere where Earth's axle of revolution joins its surface. The South Pole is another location; where the axis of Earth's circumrotation intersects its facade, in Antarctica. The geographical poles of the North and South Poles of the Earth move a few meters over a period of few years.

The poles cannot move 10 km a year because they are connected to earth which moves way more than that

FinnZ [79.3K]

Answer:

C)Parental: 41% Dr, 41% dR; recombinant: 9% DR, 9% dr.

Explanation:

The notation Dr/dR for genotypes means that one homologous chromosome has the alleles Dr and the other homologous chromosome has the alleles dR.

The heterozygous plant  Dr/dR will produce 4 types of gametes: two identical to the chromosmes the individual has in its somatic cells (called parental), and two gametes which will be a mix of the alleles in the homologous chromosomes (called recombinant).

  • Dr: parental
  • dR: parental
  • DR: recombinant
  • dr: recombinant

To calculate the frequency of each type of gamete, we must use the formula:

Distance (map units) / 100 = frequency of recombination.

18 mu / 100 = 0.18.

The total frequency of recombination between the genes D and R is 0.18, but every time crossing over happens, two recombinant gametes are generated. Therefore, each recombinant gamete will have a frequency of 0.18/2=0.09 = 9%.

The frequency of parental gametes will be:

1 - frequency of recombinant gametes

1 - 0.18 = 0.82

But there are 2 parental gametes, so each of them will have a frequency of 0.82/2=0.41 = 41%.

How do the base-pairing rules explain how a strand of DNA acts as a temple during DNA replication?
Ne4ueva [31]

This means that each of the two strands in double-stranded DNA acts as a template to produce two new strands. Replication relies on complementary base pairing, that is the principle explained by Chargaff's rules: adenine (A) always bonds with thymine (T) and cytosine (C) always bonds with guanine (G).
