Answers

Answer:

Ozone, or trioxygen, is an inorganic molecule with the chemical formula O ₃. It is a pale blue gas with a distinctively pungent smell. It is an allotrope of oxygen that is much less stable than the diatomic allotrope O ₂, breaking down in the lower atmosphere to O ₂.

The diagram shows a process that occurs in eukaryotic cells.

Answers

The diagram shows the process of transcription of gene for making proteins.

The diagram shows a process that occurs in eukaryotic cells is transcription of gene for making proteins because the diagram represents the structure of DNA. Transcription is the process of making an RNA copy of a gene sequence. This copy is known as messenger RNA (mRNA) molecule.

This messenger RNA leaves the cell nucleus where it is produced and enters the cytoplasm where it directs the synthesis of protein which it encodes so we can conclude that the diagram shows the process of transcription of gene for making proteins.

An increase in body fluids leads to an increase in kidney filtration which leads to an increase in kidney output (urine). What type of feedback is this?

Answers

Answer:

Positive feedback.

Explanation:

An increase in body fluids causes increase in kidney filtration which leads to higher production of urine, this type of feedback is known as positive feedback because when there is increase in the output, this is called positive feedback while on the other hand when there is decrease in the output we called it negative feedback. So we can see that the output of the kidney is higher concentration of urine so we can say that it is a positive feedback.

If
there were suddenly no sunlight

affect the ability of plants to
produce carbohydrates?

Answers

since this means it wouldn’t receive sunlight, it would no longer have the ability to create food or carbohydrates for itself and would eventually die.

As we know that plant needs sunlight for performing the process of photosynthesis and by the process of photosynthesis produce food and if there is no sunlight than plant will not be able to produce sunlight and this will affect the ability of plant to produce carbohydrate.

What is photosynthesis?

Green plants contain chlorophyll and they prepare there own food in the presence of sunlight and the process is known as photosynthesis. In the process of photosynthesis light  energy converted into chemical energy.

Carbohydrates is defied as that contains biomolecule that contains carbon hydrogen and oxygen in a ratio of 2:1. Carbohydrates are mane source of energy of the body they work as fuel for the brain, kidneys central nervous system and heart muscle.

[tex]Cn(H2O)n[/tex]is the basic formula for all carbohydrates . But this formula have limitation i.e it applies where same amount of carbon and water are use.Initially the terms carbohydrate was used to describe compounds that have really contains carbohydrates.  Because they had simple formula[tex]CH20.[/tex]
