Answer:

Monohybrid cross:

Monohybrid cross may be defined as the cross done by taking single trait at a time. The ratio of the monohybrid cross by the pure parent breed result in the formation of 3:1 phenotype in the second generation.The genotype ratio is 1:2:1.

Test cross:

Test cross may be defined as the cross between the unknown genotype and the recessive parents. This cross is done to determine whether the genotype is heterozygous or the homozygous dominant trait. The ration of the cross may vary depending on the genotype of the organism.

at which location does gravity play a role in moving tectonic plates? at the edge of the plates. in the core. in the mantle. in

yulyashka [42]

Answer:

B. At the edge of the plates

Explanation:

Gravity is the principal driving force of plate tectonics (second one is convection). It causes different density plates to move on the Earth's surface. However, when a denser plate coincides the less denser plate, the high density plate subducts below the lesser density plate. The process, therefore, is called subduction. During this collision of plates, shearing resistance increases and all pressures come at the edge of the plate. The process continues and the lithosphere drags the rest of the plate. The portion of plate below the less denser plate then reaches the mantle. Here, the edge of plate is destroyed due to high temperature of mantle as well as pressure.

Thymine dimers can be repaired by Photoreactivation Repair or Nucleotide Excision Repair. - true or false?

Aleksandr-060686 [28]

Answer:True

Explanation:Basically thymine diamers are mismatched pairs (thymine binds with another thymine instead of binding with adenine) and may lead to unwanted results so the mismatching can be repaired by using two methods which are as follows :

1-the PRE enzyme activated by blue light breaks the thymine diamer and some of the surrounding bonds the strand is cut and DNA polymerase then restores the normal base pairing

2-UVR system breaks dimer creating a gap when a gap is created and the molecules appear unpaired it is filled by proof readers hence restoring normal base pairing.

in lab micr the short tail phenotype is fominant to wild long assuming tail length is controlled by a single locus a likely expl

Ne4ueva [31]

Answer:

The answer is "Option e".

Explanation:

please find the complete question in the attached file.

Its long tail disregards its short tail. Let's assume that even a short neck is a as well as a tail over, which claim, though, the short tails were mixed, shorter, and longer tailed mousses are created. It may also presume that the short mouse parental is always Aa. And we get AA, Aa, Aa, Aa, and Aa situations once their matter and they fall pregnant to both high and short tail mice but we wouldn't get the fat tail mouse unless the tail-mouse were as AA.

we always get two types of lines. It demonstrates there was no uniform AA genera. It is a case of the heterozygous dangerous gene, that can cause a set of identical alleles inside an organism to always be lethal.
