b. leaching
Minerals found in the B horizon were dissolved in water and carried there by a process called leaching
their appearance and functions are different.
This is because the liver cell
(1) contains different genes than the muscle cell
(2) expresses different genes than the muscle
cell
(3) destroys the muscle cell genes it contains
(4) lacks the genes found in muscle cells
Answer: The correct answer is-
(2) expresses different genes than the muscle cell.
Liver cell and muscle cell in human are developed from the same single cell but perform different functions that is they are specialized to perform particular function.
It is because there is differential expression of genes in these cells. In other words, specific genes are turned on to perform specific functions and other genes are turned off.
Gene expression means transcription ( formation of mRNA from DNA) and translation ( formation of protein from mRNA) of gene ( a DNA segment, which codes for particular protein) so as to form a specific protein or polypeptide.
The protein thus produced, provides specific function to the cell.
Thus, different genes are expressed in specialized cells ( such as muscle and liver cell), which enables them to perform specific functions.
b. Graduate
c. Secondary
d. Primary
Answer:
the convective zone of the sun
Explanation:
In the the convective zone of the sun the energy is carried upwards by the rising hot gas and subsequently it cools and descends, that is to say that the energy is transported mainly by means of convection.
In this area, circular current patterns are formed where the hot plasma rises and the cold plasma descends.
b. greater than the concentration of carbon dioxide in the air or water.
c. lower than the concentration of oxygen in the air of water.
d. lower than the concentration of carbon dioxide in the air or water
