Answer:

In humans the genetic commonality of height and skin tone is that they are both <u>Polygenic Traits.</u>

Explanation:

Polygenic traits can be described as those characteristics for which there is more than one gene to determine its inheritance. The outcomes of polygenic genes result in many differentiated phenotypes. For example, the difference in height, the difference in skin colour etc.

Polygenic traits occur because one allele for a gene does not have complete dominance over the other gene. This is termed as incomplete dominance. Incomplete dominance is a Non- Mendelian trait as Mendelian traits showed one allele to be completely dominant over the other allele.

In the northern hemisphere, winds associated with a low-pressure system system blow ___. ?

Lelu [443]

<h3><u>Answer;</u></h3>

A. counterclockwise toward the center

<h3><u>Explanation;</u></h3>

<em><u>In the Northern Hemisphere, winds associated with a low-pressure system blow in a counterclockwise direction towards the center, while those that are associated with a high-pressure system blow in clockwise direction outwards from the center.</u></em>
In the Southern Hemisphere on the other hand, winds that are associated with a low-pressure system blow clockwise towards the center.
<em><u>The rotation of the earth creates a force called the Coriolis force, which gives the wind that is within high pressure systems a clockwise circulation in the northern hemispheres and a counterclockwise circulation in the southern hemisphere.</u></em>

Hamilton’s rule states that:

Papessa [141]

Answer:

The correct answer is option D.

Explanation:

Hamilton rules state that any trait that helps in benefiting others, B, is multiplied by genetic relatedness, R, which is greater than cot to self, C, it is favored by the process of natural selection.

As indicated by Hamilton's rule, the kin selection makes qualities increment in recurrence when the hereditary relatedness of a beneficiary to an actor multiplied by the advantage to the beneficiary is more noteworthy than the regenerative expense to the actor.

Thus, the correct answer is option D.

Which mitotically inactive portion of the root tip acts as a reserve of healthy cells in case the apical meristem becomes damage

Kamila [148]

The quiescent center is the mitotically inactive portion of the root tip that acts as a reserve of healthy cells in case the apical meristem becomes damaged.

Quiescent center cells exhibit high resistance to ionizing radiation, especially when compared to surrounding initial cells, leading to the hypothesis that the quiescent center functions as a stem cell reservoir, ensuring the rejuvenation and perseverance of the root apical meristem.

The root quiescent center is a pool of rarely dividing stem cells inside the root apical meristem. The Quiescent center maintains the environment more regularly by dividing initials, forming the root apical meristem cell niche.
