Answer:
The correct answer is option A, that is, cotransport proteins.
Explanation:
The variable that possesses the tendency to mediate energy based on chemical potential is termed as an electrochemical gradient. The electrochemical gradient is differentiated into two parts, that is, electrical gradient and chemical gradient. Both these forms of gradient take place over the surface of a membrane.
The movement of the majority of the ions takes place by the phenomenon of electrochemical gradients, of which some are found on the surface of the membrane and function as electrogenic pumps. While the gradients of some of the ions are mostly accounted for by the co-transport proteins, as these proteins take part in the movement of ions or molecules through a plasma membrane that involves concentration gradient based on the kind of molecules and movement.
Answer:
The correct answer is A) differentiated cells retain all the genes of the zygote
Explanation:
A plant can be cloned from the somatic cells which shows that the differentiated cell of plants have the ability to divide and differentiate to produce a new plant. This property of the cell is called totipotency.
All the cells in plants are not totipotent but some cells under proper condition can show the property of totipotency. Totipotency property shows that the differentiated cell is having all the genes that were present in the zygote.
This property of plant cells is used by scientist in plant tissue culture to produce plants for research and other purposes. So the right answer is A.
Answer:
C. The rates of birth and immigration were balanced by the rates of death and emigration
.
Explanation:
A stable population size means that, over the years, number of individuals doesn't change significantly. This condition is only possible when the birth rate and immigration rate is balanced with the death rate and emigration rate. In this scenario, population size would not change much.
On the other hand, if a birth rate and immigration rate will increase, the population size in any area would be increased. This typically happens in growing cities. By contrast, if death rate and emigration rate increases, the size of population will decrease. This happens mostly in rural areas.
The parents alleles would be GG and gg. the reason why is if they were both GG they would all be GG. If they were both gg all the offspring would be gg. hope this helps.
