Why does cell division remain important to an adult organism even after it is fully developed?

Biology
1 answer:
Sloan [31]3 years ago
3 0

Answer:

Cell division prevents cancers, and is something that in humans and in other adult organisms as well prevents old age.

There are many more complex mechanisms that contribute to old age and cancers, but if cell division slows down an organism reaches the end of its life.

Every set of cells has a limited amount of divisions it can do. literally every organism from the moment of conception is dying.

A cell that has 6 chromosomes in the G2 phase will have how many sister chromatids during that same phase
dimulka [17.4K]

Answer:

12 chromatids.

Explanation:

If a cell has 6 chromosomes in the G2 phase will have 12 sister chromatids during that same phase because replication of chromosomes occurs which produces two exact copies of each chromosomes. Then 6 chromatids are distributed in one daughter cell while the other 6 chromatids are distributed in other daughter cell and finally the cell division occurs.

For the enzymatically catalyzed reactions shown below, classify the enzymes as oxidoreductases, transferases, hydrolases, lyases
Elodia [21]
I found the full exercise on the internet. Attached are the images of <span>enzymatically catalyzed reactions.

Reaction a) - </span>acyl phosphate to carboxylate and phosphate.
The enzyme that catalyses this reaction is the a<span>cylphosphatase, which is a hydrolase, because it uses molecules of water in the reaction.

Reaction b) - </span><span>ATP + an L-amino acid + an L-amino acid </span>to<span> ADP + phosphate + L-aminoacyl-L-amino acid.
The enzyme that catalyses this reaction is the </span><span>L-amino-acid alpha-ligase, which is a ligase because it preforms the bonding of two large molecules.
</span>
Reaction a) - glucose-1-phosphate to glucose-1,6-bisphosphate to glucose-6-phosphate
The enzyme that catalyses this reaction is the Glucose-1,6-bisphosphate synthase, which is a transferase because it transfers a phosphate group from a <span>donating to an accepting molecule.

Reaction b) - </span>NAD^{+}+H_{2} O to NADH+H^{+}<span>
The enzyme that catalyses this reaction is a </span><span>oxidoreductase because it helps oxidising and reducing molecules.

Reaction c) - </span>α-keto acid + Glutamate to Aminoacid + α-ketoglutarate
The enzyme that catalyses this reaction is an aminotransferase, which is a transferase because it transfers an amino group from a donating to an accepting molecule.

Reaction c) - produces a molecule of CO^{2}
The enzyme that catalyses this reaction is a Carboxy-lyase, which is a lyase because it adds or removes carboxyl<span> groups from organic molecules.</span>

One reason farmers might choose non-GM crops over GM crops is because non-GM crops are A. less safe. B. more productive. C. less
EleoNora [17]
C, probably, seeing as non -gm crops are definitely not as controversial, and its definitely not A and B. <span />

Describe sporangium fungi and club​
leva [86]

Answer:

A sporangium (pl., sporangia) (modern Latin, from Greek σπόρος (sporos) 'spore' + ἀγγεῖον (angeion) 'vessel') is an enclosure in which spores are formed. It can be composed of a single cell or can be multicellular. All plants, fungi, and many other lineages form sporangia at some point in their life cycle.
