Could life as we know it exist on earth if air contained only oxygen? Explain

1 answer:

6 0

Oxygen in it's purest form is a deadly gas that would kill is almost instantly. It is the cause for most (if not all) cases of combustion. We breath in two molecules of oxygen, which stabilizes the compound and allows us to dispel carbon dioxide safely. It only comprises a small part of the atmosphere though. The air is made up of around 93% nitrogen, which is vital for the survival of certain species on earth. There is also a carbon cycle in the air which will be destroyed, given that only oxygen was in the atmosphere.

If your carbohydrate consumption was low, then the process of making ATP would quickly diminish. Carbohydrates are the main source of energy to cells, and it's because of them that we can make ATP.

This would affect your cells by slowing them down, which ultimately slows you down as a whole. If it gets too serious, death can occur.

A drug binds to a receptor in the nucleus. This binding turns on a gene to make a protein. This drug is ____. lipophilic and hyd

Serjik [45]

The drug that to a receptor in the nucleus. This binding makes on a gene to make a protein. This drug is actually lipophilic and hydrophobic, the correct option is A.

What is receptor?

In biochemistry and pharmacology, receptors are protein-based chemical frameworks that transmit and receive signals that can be assimilated into biological systems.

As the drug is crossing the lipid membrane so it should be lipophilic and hydrophobic to be able to bind the receptor as in the given situation.

Thus, the correct option is A.

Denitrifying bacteria convert nitrate into _____, thus returning nitrogen to _____.

ziro4ka [17]

Denitrifying bacteria convert nitrate into <u>nitrogen gas</u>, thus returning nitrogen to the <u>atmosphere</u>.

Denitrifying bacteria- Numerous phyla are included in the broad class of bacteria known as denitrifying bacteria. This group of bacteria, which is a part of the nitrogen cycle, may carry out denitrification together with denitrifying fungi and archaea.

Phylum (Phyla)- In biology, a phylum is a rank or level of taxonomic categorization that comes after a kingdom but before a class. Although the nomenclature for algae, fungus, and plants is recognized by the International Code of Nomenclature as being equivalent, division rather than phylum has traditionally been used in botany.
