Answer:

Viruses mutate very quickly The major reason that viruses evolve faster than say, mosquitoes or snakes or bed bugs, is because they multiply faster than other organisms. And that means every new individual is an opportunity for new mutations as they make a copy of their genetic material. Many of those mutations have no noticeable effect.

Which of the following have been linked to the dramatic global decline of amphibian populations? Select one: a. drainage of wetl

charle [14.2K]

<h2>The correct answer is: e.</h2>

Explanation:

Decline in the global population of amphibians is due to multiple reasons which include:

A moist ecosystem is necessary for amphibians especially for the purpose of their reproduction. The drainage of the wetlands deprives them of their habitat.
Pollutants adversely affects the survival of the gametes, tadpoles or the adult amphibians by acting as toxic agents and inhibiting their normal metabolic function.
Infectious diseases often cause their death resulting their population to decline.
Global climate warming affects their normal metabolic growth and development and hence causes their population to decline.

!!Help!! In dogs, the gene for fur color has two alleles. The dominant allele (F) codes for grey fur and the recessive allele (f

tatiyna

Answer:

% GENOTYPE

FF = 0%

Ff = 50%

ff = 50%

% PHENOTYPE

Black fur = 50%

Grey fur = 60%

Explanation:

This question involves a single gene coding for fur color in dogs. The allele for grey fur (F) is dominant over the allele for black fur (f). This means that a heterozygous dog (Ff) will have a grey fur.

In this question, a heterozygous female (Ff) is said to cross with a recessive male (ff) i.e. Ff × ff. The following gametes will be produced by each parent:

Ff - F and f

ff - f and f

Using these gametes in a punnet square (see attached image), the following genotypic proportion of offsprings will be produced:

Ff - 1/2 = 50%

ff - 1/2 = 50%

Ff is phenotypically GREY while ff is phenotypically BLACK. This means that 50% of the offsprings will be black and 50% will be grey.

The formation of the enzyme pepsinogen

Dafna1 [17]

Answer:

1) First the DNA strands unwind, and RNA polymerase binds to the template strand.

2) Then synthesis of mRNA begins.

3) Then mRNA undergoes intron splicing and exits the nucleus.

4) Then tRNA moves through mRNA with the activated amino acids

attached to it.

5) Lastly, amino acids assemble s to form peptide.
