Answer:
Equal amounts of DNA contain equal proportions of nitrogenous bases.
Explanation:
According to Chargaff's rule, the nitrogenous base pairs (Purines and pyrimidines) have an equal ratio (1:1) in the DNA of all the organisms. More precisely, the amount of adenine is equal to thymine and the amount of guanine is equal to cytosine in the DNA of all the organism. A-T base pair has two H-bonds while G-C base pair has three H-bonds.
LOCAL ENVIRONMENT ISSUE:
People dump a lot of trash in the sea, and the sea creatures living there goes through a lot of trouble to live with all the muck getting in them. Of course, don't write it like that in your assignment - you'll get told off for the straight forwardness.
How old it is compared to another specimen in relation.
If the size of a cell increases it will be more difficult (all other things being equal) for diffusion to transport materials out of the cell. Therefore, less of the cell's interior will be able to come in contact with the cell's surface. If less of it comes in contact, less of it can cross the cell membrane.
hope this helps and please mark me as brainliest please
Enzymes can be inhibited in different ways this can inclued three types of reversible enzyme inhibition: competitive, non-competitive and uncompetitive.
<h3>How can enzymes be inhibited?</h3>
Irreversible and reversible enzymatic inclusion. A valent-chain inhibitor occurs with a valent-chain inhibitor, whereas a valent enzyme does not occur with a valent-chain inhibitor.
In enzymatic inhibition, the inhibiting substance forms chemical bonds with the enzymes in order to interfere with their catalytic activity. This inclued types of enzyme inhibition:
- Irreversible inhibitors bind to enzymes leading to their definitive inactivation. These inhibitors are very toxic to the body as they are not specific, being able to inactivate any enzyme.
- Reversible inhibitors can be divided into two groups: competitive and non-competitive. This division is based on the presence or absence of competition between the inhibitor and the substrate for the active center of the enzyme.
