Answer:
<em>The correct option is C) Cells do not use the same sections of DNA in the same proportions, at the same time in development, which leads to differentiation.</em>
Explanation:
All the cells in an organisms body comprise of the same DNA. However, each cell is specialized to perform a different function because a part of the DNA which is active in one cell might not be active in the other cells. In this way, cell differentiation occurs. The genes which are being transcribed in one cell type may be completely repressed in the other cell type. As a result, variations occur in the structure and function of different cells.
The true statements are:
1) Catabolism is the process in which complex substances are broken down, yielding a net output of energy.
Catabolism reactions break down macromolecules (lipids, proteins, nucleic acids and sugar) into smaller units that can be used for further reactions, for energy, for the synthesis of new polymer molecules or be simple waste products.
2) Metabolism is an integrated system in which many of the same reactions participate in degradative (catabolic) and biosynthetic (anabolic) pathways.
Metabolism combine all chemical reactions of an organism. Functions of metabolism include: providing energy form food molecules, synthesis of building blocks of the cell, elimination of the waste products.
3) Anabolism involves the synthesis of polymeric biomolecules and complex lipids from monomers such as fatty acids and nucleotides.
Anabolic reactions are opposite of those in catabolism: these reactions require energy (endergonic processes) for the synthesis of necessary molecules for the cells. That energy is the product of catabolic reactions.
Answer:the water snake
Explanation:
nothing would be eating the snake and it would have more food to eat due to the crocodile not eating the other animals
