The cell walls of plants and algae have openings, or channels. How is this structure most likely related to the functioning of a

plant system? It provides further support to the cell by making the cell wall more rigid. It allows water and other molecules to enter and exit the system. It ensures that all the organelles receive an equal amount of sunlight.

Answer:

It allows water and other molecules to enter and exit the system.

Explanation:

Plants have both a cell membrane and a cell wall. These allow needed molecules, such as water, to enter the cell. Both the cell wall and the cell membrane are semi permeable, which means that they choose what can enter and leave the cell. Molecules like water and other useful things to the cell enter it, and things such as waste leave the cell through the membrane and wall.

Remember that only plant cells have cell walls. Animal cells only have a cell membrane. But both the wall and membrane have the same purpose.

if there are 500 people in a population, and 150 are homozygous HbA/hba, 150 are homozygous hbs/hbs, and 200 are heterozygous hb
sineoko [7]

Answer:

0.547

Explanation:

Given -

Total Population - 500

Individuals with homozygous HbA/hbA genotype - 150

Individuals with homozygous hbs/hbs genotype -150

Individuals with heterozygous hba/hbs genotype -  200

Let us assume the given population is in Hardy Weinberg' equilibrium

The frequency of individuals in the given population with homozygous HbA/hba genotype is equal to number of individuals with homozygous HbA/hba genotype divided by total population.

\frac{150}{500} \\= 0.3

The frequency of hba allele is equal to

\sqrt{0.3} \\= 0.5477

Because it's vital to the survival of all species, not just human, that we have resources such as food and water. Also that those resources be clean and healthy. We also need to manage resources such as oil to make sure there are fewer wars like the ones happening in the Middle East. If you need anything else just message me.
