Mollusks
Mollusks is the group of invertebrates that made up the majority of the Marine species. Their bodies tend to not divided into segments like other organisms.
Answer :B. By changing the shape of the enzyme's active site.
check the attachment
Explanation: This is a type of inhibition , in which a molecule binds to another part of the enzyme instead of the active site.
On binding, it disrupts the normal hydrogen bond and hydrophobic interactions holding the enzyme molecule in its three dimensional shape, therefore distorting the conformation and ACTIVE SITE of the enzyme (changed it shape).
Since the active site is the precise location enzyme must bind with substrates for enzymatic reactions,this makes the enzyme not fit for binding with the substrate, therefore the efficiency is reduced. No substrate-enzyme complex, and hence no substrate-product complex for the release of products, this brings down the turnover rate and eventually
<u>the rate of reaction of the enzyme</u>
Thus, the enzyme function is totally blocked, even in high concentration of the substrate,
Becuase the cell has a lower concentration that the solution it is placed in, the solution is considered hypertonic. The cell will lose water through osmosis and will shrink, the 2nd option is correct.
A small change in a persons DNA can cause any number of mutations that may be completely harmless or fatal depending on where the mutation (change) occurs in ones DNA.
Answer:
An organelle is a subcellular structure that has one or more specific jobs to perform in the cell, much like an organ does in the body.
Explanation:
Some examples of organelles are endoplasmic reticula, Golgi apparatus, lysosomes, vacuoles, mitochondria, plastids, and nucleus.
