Which statement describes an advantage of asexual reproduction?

Which of the following best describes the large evolutionary changes that take place of thousands to millions of years and produ

Sliva [168]

Answer:

2. macroevolution

Explanation:

Macroevolution refers to the evolutionary processes that lead to the appearance/extinction of groups larger than individual species. Macroevolutionary processes include speciation, species selection and punctuated equilibrium. The punctuated equilibrium processes are represented by phenomena such as those cases described above. These evolutionary processes are concentrated in relatively short speciation phases caused by bursts of evolutionary changes, which are then followed by stages characterized by evolutionary stasis.

Electrolytes such as sodium and potassium control blank by helping to maintain acid-base balance

yKpoI14uk [10]

Answer:

Electrolytes are nothing but minerals that have electric charge when it is mixed in liquid like blood. thus the sodium and potassium electrolytes will help regulate the nerve and muscle function. They also maintain the acid-base balance by regulating the electric charge on the cells and water flow across the membrane.

In rabbits, short hair is due to a dominant allele, S, and long hair to its recessive allele, s. Black hair is due to a dominant

Natali5045456 [20]

Answer:

SsBB x SsBB

or

SsBB x SsBb

Explanation:

SS- short hair

ss - long hair

BB- black hair

bb- white hair

Total the number of offspring produced = 2518+817=3335

Where 2518= short haired, black offspring SSBB or SsBb

817= Longed Hair, black offspring ssBB or ssBb

To get the offspring proportion for short hair black offspring

2518/3335×100 = 75.5%

long-haired, blackoffspring =817/3335×100 = 25%

This gives ratio of 3:1 as against the proposed dihybrid phenotypic ratio of Mendel experiment 9:3:3:1

Now, if you remember a dihybrid cross results in 9:3:3:1 phentoype ratio. That is when both parents are heterozygous for both alleles. So we can rule that out since it doesn't match our 3:1 ratio.

Since all the offspring are black , it means one parent is homozygous dominant for black and the other parent is either homozygous or heterozygous for the black allele.

Since the ratio is 3:1, for the hair length

That leaves us with the short hair. Since the ratio is 3:1, both parents are heterozygous for hair length.

Therefore, the possible parental genotype is

SsBB x SsBB

or

SsBB x SsBb
