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.
Answer:B) progress towards the replication fork.
Explanation:
Replication fork is a point on the parental DNA where the DNA is being unwound and separated; and the separated strands are being replicated. Synthesis of a new DNA strand occurs in a 5' -> 3' direction, as the DNA strand serving as the template is read from its 3' -> 5' direction. During replication, two strands of DNA are synthesized: The leading strand is synthesized continuously in the same direction as the replication fork movement while the lagging strand is synthesized discontinuously in the direction opposite to the direction of fork movement, that is, towards the replication fork. The lagging strand is synthesized in short fragments known as Okazaki fragments.
Multipotent cell
is a kind of atem cell that can only develop into cells that are closely related to the original stem cell.
<u>Explanation:</u>
Our body contains stem cells which help to regenerate or repair a particular cell or tissue during the time of need. There are different types of stem cells which provide as a life saver to the individuals to recreate the tampered organ or tissue.
The multipotent cells unlike other stem cells have specific functions only. They can develop into cells that are closely related to the original stem cell. On stimuli a multipotent blood stem cell can give rice to related cells but cannot produce a neuron or other kind of cells. Hence multipotent cells are mainly used in transplantation.
Answer:In the rock cycle, rocks and matter go through uplift, weathering, erosion, deposition, melting, crystallization, and metamorphism as they travel between Earth's surface and its interior layers.
