Answer:
The correct answer would be the active transport across the cell membrane.
The main functions of the cell membrane are a barrier, regulates transport (passive, facilitated, and active), the presence of receptors et cetera.
Only active transport (such as sodium pump, calcium pumps et cetera) requires the input of energy (ATP) for proper functioning. It uses energy to pump substances against the concentration gradient.
Thus, only active transport would be affected if less cellular energy is available.
The organelle which is most likely to be missing from leaf cells is Lysosomes.
Lysosomes are an important organelle for eukaryotic animal cells as they contain the digestive enzymes. The macromolecules or foreign matter which are harmful for the cells enter the animal cells easily but not the plant cells as the plant cells contain cell walls. Phagocytosis or digestion of macromolecules is not much needed in plant cells so a lysosome can be missing from the leaf cell.
The answer to your question is A
Answer:
the answer is E sugar I think
Answer:
The number will be 208 after third generation.
Explanation:
Meiosis is a type of cell division that occur in eukarytotic reproductive cells and it divide diploid chromosomes into haploid chromosomes. Nuclear division happen twice in meiosis.
The diploid number for the chromosome number of frog is 26. There fore if there is no occurrence of meiosis before gametes are formed there won't be any reduction in the number of chromosomes. The gametes will be diploid and it will have the same number of chromosomes as the parent cell which is 26. Zygote will be formed after the egg fuses with the sperm.
The first generation will be 26 + 26= 52.
Second generation is 52 + 52=
104.
Third generation is 104 + 104 = 208.
The chromosome number will be doubling from generation to generation if meiosis did not occur. After theirs generation it will be 208.
