Answer:
The carbon, phosphorous, water and nitrogen cycles are considered to be biogeochemical cycles because all of the cycles are cycles in which chemical and simple substances are transferred between living systems and the environment. Simply put, they all include the biosphere, chemical Please Mark Brainliest If This Helped!

Answer:
Hey, I answered your last question(the same one), so you should check the last question you posted.
Answer/Explanation:
Yes, although they have similarities, meiosis and mitosis are different.
<h3>Similarities</h3>
Meiosis and mitosis are both types of cell division that results in the production of daughter cells.
They go through similar processes of prophase, metaphase, anaphase, and telophase.
<h3>Differences</h3>
However, mitosis produces two genetically identical diploid daughter cells from a diploid parent cell.
Meiosis produces four genetically different haploid cells from a diploid parent cell.
There are two rounds of cell division in meiosis, and only one round in mitosis.
Answer:
Once starch reaches small intestine, it needs to be broken down into smaller units with the help of <u>hydrolysis reaction</u>. Pancreatic amylase catalyzes this reaction which ultimately breaks down glycosidic bonds present in starch molecule to produce simpler bio-molecules like maltose, dextrin etc.
Uses of carbohydrate in body:
(1) It is primary source of energy in the body;
(2) It is required by the body for storage of energy in the form of glycogen;
(3) In plants, it is required for building cellular structures like cellulose.
Explanation:
In order for starch to be digested in the intestine, it needs to be hydrolyzed with the help of pancreatic amylase. The hydrolysis reaction breaks the glycosidic bonds of starch molecule which is a polymer leading to the release of smaller molecules like dextrin, maltose etc. Maltose which is a disaccharide is further broken down into even smaller monomeric units like glucose with the help of enzyme known as maltase.
After conversion into monomeric unit i.e. glucose now it can be absorbed by the blood stream. The blood transports these small glucose molecules to all the cells of the body. After entering the cell, the glucose is used for the production of energy/ATP via cellular respiration.
During cellular respiration, the glucose is first converted into pyruvate via glycolysis. Pyruvate then enters PDH complex wherein it is oxidatively carboxylated into acetyl coenzyme A. The acetyl coenzyme A produced then enters TCA cycle and produce high energy molecules like NADH, FADH₂ and ATP. The NADH and FADH₂ then finally enter electron transport chain (ETC) so as to produce ATPs. These ATPs are then utilized by our body for our day to day activities.
