Alleles A and a are located on a pair of metacentric chromosomes. Alleles B and b are located on a pair of acrocentric chromosom
Leto [7]

Answer:

See the second attached image showing the gametes from the parent with the location of the centromere indicating the type of chromosome

Explanation:

According to the position of the centromere, chromosomes can be of 4 types namely:

  1. Metacentric
  2. Acrocentric
  3. Telocentric
  4. Sub-metacentric

A metacentric chromosome is a chromosome that has no short or long arm. The arms are equal in length with the centromere joining the two sister chromatids located at the center.

Acrocentric chromosomes have unequal arm lengths with the centromere skewed towards one end of the chromosome.

Telocentric chromosomes have their centromeres at one end of the chromosome.

Sub-metacentric chromosomes have unequal arm lengths but the centromere is not as skewed to one end of the chromosome length as found in acrocentric chromosome.

The only possible gamete from <em>aa bb</em> parent is <em>ab</em>. Recall that the allele <em>a </em>is located on a metacentric chromosome while allele <em>b </em>is located on acrocentric chromosome.

Many scientists predict stronger storms, warmer oceans, and lower ocean pH in the future. If this occurs, how do you think these
Y_Kistochka [10]

Answer:

It wouldn't be able to survive

Explanation:

If the pH goes up than the coral reefs wouldn't be able to live and if they can't live there then there wouldn't be any life. There wouldn't be shelter for the fish and if there is no fish then the ecosystem would collapse.

The Coriolis Effect is caused by Earth’s uneven distribution of heat AND ________________.
SCORPION-xisa [38]

The rotation of the earth

The Coriolis Effect is caused by Earth’s uneven distribution of heat AND the rotation of the earth

Explanation:

Due to the spherical nature of the earth, when it spins, around its axis, different latitudes spin at different rates. The nearer to the pole you get the slower the earth’s spins (approx 0.00008 kilometers/hr), while this spin is fastest at the equator ( approx1,600 kilometers/hr). Due to this differential spin, ocean and winds currents (while they move polewards due to convection) are deflected as they move towards the pole from the equator. Towards the North, they are deflected westwards while towards the South they are deflected eastwards.
