The correct answer is that different genes are expressed in different cells.
The cellular differentiation is the process in developmental biology where a cell modifies from one kind of cell to another. Most generally the cells are modified to a more specialized kind. Differentiation takes place various times at the time of development of a multicellular species as it modifies from a basic zygote to a composite system of tissues and kinds of cells.

In biology the word <em>bio</em><em> </em><em>catylysts</em><em> </em>describes the word enzymes . Bio catylysts are nothing but enzymes which alter the rate of reaction . For ex - Pepsinogen , which is produced in the stomach of humans activated by HCl from a proenzyme called trypsin . It works in acidic medium and converts proteins into peptides and protons . Likewise there is another enzyme called Salivary amylase which is present in the saliva of humans converts starch into maltose . There is another enzyme called lipase which converts fats into fatty acids and glycerol .
Answer: 2) The cell grows to its mature size.
Explanation:
The G1 phase is often referred to as the growth phase, because this is the time in which a cell grows. During this phase, the cell synthesizes various enzymes and nutrients that are needed later on for DNA replication and cell division. ... The G1 phase is also when cells produce the most proteins.
The correct answer for the question is B, ATP contains less potential energy than ADP.
Explanation;
ATP contains more energy potential than ADP , since it has three phosphate bonds unlike ADP which has 2 phosphates.
A. is true; During glycolysis ATP is formed, Glycolysis uses 2 ATP molecules and also generates four ATP molecules which gives a net energy of 2 ATP molecules.
C is true, as plant cells generate ATP during cellular respiration. Cellular respiration is the process in which cells generate energy in form of ATP through oxidative phosphorylation in the mitochondria.
D. is true; ATP is used as a mobile energy carrier molecule by all cells. It used by these cells to fuel all cellular activities.
