Answer:

The answer is 2) a comet

Explanation:

Comets are celestial bodies made up of ice, dust and rocks that revolve around the Sun. They are made of ice, such as water, carbon dioxide, ammonia and methane, mixed with dust. A comet heats up as it approaches the sun, whose heat causes the ice in the core to become gas; The pressure of sunlight and high-speed solar particles blow the comet's materials away from the sun, forming a long and sometimes bright tail.

In chickens, the allele for a pea comb (A) is dominant to the allele for a single comb (a). A mother with the genotype Aa and a
zloy xaker [14]

Answer:

The percent chance that the offspring will have a single comb is 25 %

Explanation:

Given,

The allele for single comb represented as "a" is recessive to the allele for pea comb represented as "A"

Genotype of male - Aa

Genotype of female - Aa

Gamete of Male - A, a

Gamete of female - A, a

Cross between Aa and Aa will produce

AA, Aa, Aa, aa

Thus, out of four offspring only one has "aa" genotype and hence this individual will express the recessive trait i,e  aa

The percent chance that the offspring will have a single comb is

\frac{1}{4} * 100\\

25 %

Iteru [2.4K]

Answer:

There is an important relationship among  homeostasis, defective mitochondria, and the  symptoms caused by LHON.

Explanation:

There is a great relationship among  homeostasis, defective mitochondria and the  symptoms caused by LHON because defective mitochondria disturbs the homeostasis in the body. If mitochondria works properly, homeostasis will be maintained whereas if there is any defect occurs in the mitochondria then the whole homeostasis will be adversely affected because mitochondria is the powerhouse of the cell responsible for the production of energy for the cell. Symptoms occurs due to Leber's hereditary optic neuropathy (LHON) also effected the state of equilibrium in the body.
