Why are diploid cells abbreviated 2n and haploid cells abbreviated 1n​
Ganezh [65]

Answer:

Diploid cells abbreviated 2n and haploid cells abbreviated 1n​ because 'n' represents number of chromosome present in the cell. In haploid cells the number of chromosome is half in number while in diploid cells the number of chromosome is double so that's why haploid is abbreviated as 1n and diploid is abbreviated as 2n.

Diploid cells are present in body cells while haploid cells are found in sex cells.

Hypertonic environment

<h3>How do salts and sugars preserve food?</h3>

Salts and sugars work to preserve foods by creating a hypertonic environment. Salt and sugar will remove the water from the bacteria or fungi and they will not be able to proliferate. Loss of water results in plasmolysis, or cytoplasmic shrinkage.

<h3>What is hypertonic solution and plasmolysis?</h3>

Compared to another solution, a hypertonic solution has a higher solute concentration.

Plant cells subjected to hyperosmotic stress frequently exhibit plasmolysis as a reaction. The live protoplast violently separates from the cell wall as a result of the loss of turgor. The vacuole is primarily responsible for the plasmolytic process.

There are marked differences in the type of organisms found at four different locations at the same tidal height along ta rocky
yawa3891 [41]

Answer and Explanation:

Many elements can be responsible for this, among them, we can mention the presence and absence of predators in the different places on the rocky coast. This is because predators can influence not only the number of organisms found, but also the types of organisms.

Another element that may be the cause of this variability is the availability of resources necessary for the life of these organisms, in addition, the impact of the waves on the rocks, can cause the variability of the organisms, since some may not be able to resist the impact of the waves.
