Answer:
The presence of new nucleus in the cell
Explanation:
If the cell have true nucler then it is eukaryotic,but when it is having not true nuclear in the cell then it is prokaryotic
B, (layer C is the youngest layer) :)
Over time, rain and weathering causes rocks to release phosphate ions and other materials. This inorganic phosphate is then distributed into the soil and water. plants take up inorganic phosphate from the soil. the plants may then be consumed by animals. Once in the plants or animal, the phosphate is incorporated into organic materials that break down organic matter to inorganic forms of phosphate. this process is known as mineralisation. Phosphate in soil can end up in waterways and eventually oceans. once there, It can be incorporated into sediments over time.
The corect answer is: B. Intercalated disks.
I hope that helped! :)
Answer:
The correct answers are:
1 a. X^RX^r - red eye color female
b. X^RX^R - red eye color female
c. X^RY - red eye color male
d. X^rY - white eye color male
e. X^rX^r - white eye color female
(2nd part can also be answered by above)
Explanation:
It is given that the eye color is a sex-linked character where Red eye color is dominant over white eye color in fruit flies. Sex-linked characters are the character that is a similar inheritance pattern except in the case of the male as there is a Y chromosome that does not carry the gene for the eye color trait so the trait will depend on the allele present on a single X chromosome in males.
On the basis of this, the sex and color of eyes will be:
a. X^RX^r - red eye color female - Dominant character will mask the recessive white color and two copies of X which means female.
b. X^RX^R - red eye color female - both copies are dominant so red-eye color will be expressed and two copies of the X chromosome that means female
c. X^RY - red eye color male - One X and one Y chromosome that means male and only dominant allele present so red eye color.
d. X^rY - white eye color male - Only allele that is present is recessive with one Y chromosome that means male with white eye color.
e. X^rX^r - white eye color female - two X chromosomes with recessive allele which means white eye color female.
