Answer:
Mechanical weathering breaks rocks into smaller pieces without changing their composition. Ice wedging and abrasion are two important processes of mechanical weathering. Chemical weathering breaks down rocks by forming new minerals that are stable at the Earth's surface.
Answer:
they lead to quick recovery
Explanation:
they contain chemicals made by professionals which lead to quick recovery
Answer: The nucleus of a cell is like your parents. Your parents control most of things that take place inside your house. The nucleus can be represented as the brain because the brain tells the body what to do just like what the nucleus does for the cell. Without the brain you could not live.
Answer:
Products of the pentose phosphate pathway contribute to reductive biosynthesis reactions
Pentose phosphate pathway activity is high in rapidly diving cells.
Glucose-6-Phospjate is common to glycolysis and the pentose phosphate pathway
Explanation:
Glycolysis is the major catabolic fate of glucose 6-phosphate. However, oxidation of glucose 6-phosphate to pentose phosphates occurs by the pentose phosphate pathway. Therefore, glucose 6-phosphate is common to glycolysis and pentose phosphate pathway.
Pentose phosphate pathway uses NADP+ as an electron acceptor, yielding NADPH. Rapidly dividing cells, such as the cells of bone marrow and skin use the pentoses as one of the precursors for the synthesis of RNA, DNA, and coenzymes like NADH, FADH2, and coenzyme A.
The NADPH formed during pentose phosphate pathway is needed for reductive biosynthesis by many tissues. For instance, liver and adipose tissues carry out the extensive synthesis of fatty acid and require NADPH. Likewise, the tissues involved in the active synthesis of cholesterol and steroid hormones (for example, adrenal gland and gonads) also require the NADPH which in turn is provided by the pathway.
