Answer:

Gene duplication  

Explanation:

Gene duplication is an evolutionary process that includes different phenomena such as, among others, unequal crossover, chromosome rearrangement, chromosome duplication, etc. These duplicated genes are redundant in function and therefore they may accumulate mutations such as insertions or deletions at higher rates compared to single-copy DNA sequences, thereby producing homologous genomic fragments with different lengths

Answer:

They was likely a gene duplication

Explanation:

Evolutionary divergence tends to follow gene duplications, as variations in genes or mutation in one gene are no longer taken against as strongly so the individual gets a copy of a functional gene.

The shortest length of time required to kill all test microbes at a specified temperature is the thermal death ________ whereas
Aliun [14]

Answer:

time; point

Explanation:

The complete question is as follows:

The shortest length of time required to kill all test microbes at a specified temperature is the thermal death __________ whereas the lowest temperature required to kill all microbes in a sample within 10 minutes is the thermal death _________.

time; point

window; point

point; time

time; temperature

  • When a population of bacteria gets killed due to exposure to high temperatures then this is termed as thermal death.
  • The time taken to kill a specific microbe at a specific temperature is termed as the thermal death time. The length of the time taken depends on the nature of the target microbe and hence, varies from one to another.
  • The lowest temperature that will kill all the microbes in a sample within ten minutes is defined as the thermal death point. The temperature at which the microbes get killed within 10 minutes also varies from one microbe to another.
  • Thermal death results in the disruption of the cell membranes of the microbes and hence can kill the microbes.

What is the expected phenotypic ratio of the offspring of a a BbPp*BbPp cross if these alleles sort independently?
nadezda [96]

Answer:

Let's consider that the allele 'B' is for Black hair colour and it is dominant. Let's consider that the allele for red hair colour is b.

Let's consider the allele for lacking horns or polles is 'P' and it is dominant. The allele for having horns is 'p' and it is recessive.

When two heterozygous black, lacking horns (BbPp) are crossed, the results will have the probability of 9 black/polled : 3 black/horned : 3 red/polled : 1 red/horned organisms.

Explain the production of monoclonal antibodies and give an example of how they are used.
taurus [48]

Answer:

Monoclonal antibodies (mAbs) are produced by introducing an antigen to a mouse and then fusing polyclonal B cells from the mouse's spleen to myeloma cells. The resulting hybridoma cells are cultured and continue to produce antibodies to the antigen.

Explanation:

An example of a monoclonal antibody is blinatumomab (Blincyto, Amgen), used to treat certain cancer, types of acute lymphocytic leukemia.
