The main role of oxygen in photosynthesis and respiration is that Oxygen is released in photosynthesis and used in cellular respiration to produce energy.
Role of oxygen in photosynthesis and respirationIn photosynthesis, water and carbon dioxide reacts to form oxygen and glucose while on the other hand, In cellular respiration, oxygen is used to break down glucose in order to release energy in the form of ATP.
So we can conclude that the main role of oxygen in photosynthesis and respiration is that Oxygen is released in photosynthesis and used in cellular respiration to produce energy.

What is the reaction catalyzed by aminoacyl-trna synthetases that is essential for translation?.
When would your cells be most likely to use fermentation instead of aerobic respiration?.
When you are exercising.
In everyday life when you aren't doing physical activity, you get enough oxygen to move. However, when you are exercising, you're using more oxygen than how much you're taking in. When the body doesn't have enough oxygen, (when you are exercising) it switches to anaerobic respiration (or fermentation).
Hope this helps!
During exercise, the cells of the body demand more energy so they use fermentation instead of aerobic respiration and lactic acid is produced from glucose.
What is fermentation?It is the process of partial oxidation of glucose, carried out by muscle cells when they run out of oxygen to breathe.
This process generates ATP but produces lactic acid as a by-product, which, when accumulated, produces the painful sensation of muscle fatigue during exercise.
Therefore, we can conclude that during exercise, the cells of the body demand more energy so they use fermentation instead of aerobic respiration and lactic acid is produced from glucose.

How do vaccines work if the pathogen in them is dead?
Answer:
Inactivated vaccines use the killed version of the germ that causes a disease.
Inactivated vaccines usually don't provide immunity (protection) that's as strong as live vaccines. So you may need several doses over time (booster shots) in order to get ongoing immunity against diseases.

what are the differences between plant cell and animal cell
Explanation:
Plant cell:
It is found only in plants.
It consists of cell wall.
Animal cell:
It is found only in animals.
It does not consists of cell wall.
Answer:
The main structural differences between plant and animal cells are the additional structures found in plant cells. These structures include: chloroplasts, the cell wall, and vacuoles.
Chloroplasts
In animal cells, the mitochondria produces the majority of the cells energy from food. Plant cells use sunlight as their energy source; the sunlight must be converted into energy in a process called photosynthesis. Chloroplasts are perform this function. The energy conversion in plants is a complex set of reactions similar to those performed by mitochondria in animals
The Cell Wall
Another structural difference between in plant cells is the presence of a rigid cell wall surrounding the cell membrane. The tough wall gives added stability and protection to the plant cell. If you think about it, most animal cells are inside an organism that has either an exoskeleton or an endoskeleton, built in structure. Plants don't have a skeleton of any kind so the cells have to perform this.
Vacuoles
Vacuoles are large, liquid-filled organelles found only in plant cells. Vacuoles can occupy up to 90% of a cell's volume and have a single membrane. Their main function is as a space-filler in the cell, but they can also fill digestive functions and their interiors can be used as storage for nutrients.
Both plant and animal cells comprise membrane-bound organelles, such as endoplasmic reticulum, mitochondria, the nucleus, Golgi apparatus, peroxisomes, lysosomes. They also have similar membranes, such as cytoskeletal elements and cytosol. The plant cell can also be larger than the animal cell. The normal range of the animal cell varies from about 10 – 30 micrometres and that of plant cell range between 10 – 100 micrometres.

It is less specific. I know it can be hard to memorize all of the taxa but I just try to use a mnemonic (which I included below)
Explanation:
Domain
Kingdom
Phylum
Class
Order

Genus
Species
*Remember that in order to give an animal a scientific name we use the genus and species. Scientific names are always italicized and the Genus will be capitalized while the species is lowercase. The genus comes first.

If the 46 chromosomes are duplicated during interphase, why are there
still 46 chromosomes and not 92?
Before I talk about why there are still 46 chromosomes, I'll just review the basic chromosome structure. Each chromosome has a chromatid, with one centromere in the middle.
Chromosomes aren't counted by how many chromatids there are, but rather how many centromeres. When DNA duplicates, the chromatids replicate themselves, so each chromosome ends up having two sister chromatids joined at the same centromere.
There is the same number of centromeres in the cell, so there are still technically 46 chromosomes. However, there are 92 chromatids.
This used to be confusing for me too :) hope it helps!

Paragraph 3 describes the diagram at the top of this article. It demonstrates:
A: that energy flows in one direction beginning with light energy
B: the transportation of sugars into mitochondria
C: the Krebs Cycle
D: the Calvin Cycle
Photosynthesis involves a series of reactions including trapping of sunlight energy and the Calvin cycle through which plants make their food in the form of sugars.
What is metabolism?Metabolism refers to the sum of reactions that occur in a living organism which helps obtain energy and remove waste in order to sustain the life of an organism.
Different metabolic reactions take place in plants and animals.
In plants, energy is obtained from the sun and is used to drive photosynthesis.
The sugars made in photosynthesis are stored in roots, stem and tubers as well as in fruits.
The sugars can be broken down to produce energy in th mitochondria.
The Calvin cycle is the process that plants use to convert carbon dioxide and water to sugars
The Krebs cycle is a cycle which produces molecules which are used to produce energy in the mitochondria.
Therefore, since the diagram is not attached, the process shown can be understood from the explanation of each process in photosynthesis and metabolism.
