The epithelial cell will have 38 chromosomes
A 2n or 2(19) = 38 chromosomes. This is because n is called haploid number of chromosomes; the number of chromosomes present in the gametes. Epithelial cells like other body cells divides through the process of mitosis; therefore; the parent cells yields daughter cells with the same number of chromosomes (diploid). The other haploid (n) number is present in the gametes which divides by the process of meiosis.
According to the Dalton's atomic theory, we can see that there are two atoms that compose the water molecule.
<h3>What is the atomic model?</h3>
The atomic theory states that matter is made up of small particles called atoms. These atoms are capable of independent existence and can take part in chemical reaction.
From the Dalton's atomic theory, we can see that there are two atoms that compose the water molecule. These atoms are hydrogen atom and the oxygen atom.

Answer:
8 possible combinations
Explanation:
In a diploid organism (2n), there are two sets of chromosomes in each cell. Each set of chromosome is contributed by each parent i.e one set of chromosome from the father and one set from the mother.
To determine the number of possible combinations in each gamete of a cell, we use the formula 2^n, where n = number of chromosomes in haploid gametes. In this case, the cell contains 3 pairs of chromosomes, meaning that each gamete will have 3 chromosomes. However, there will be 2³ = 8 possible combinations of chromosomes in each gametes.
Answer: Marginal analysis
Explanation:
Marginal analysis is used to evaluate the marginal benefits and marginal costs of reducing pollution.
As the complexity of environmental protection grows, inexpensive and simple ways of mitigating emissions start to decrease, and more costly approaches need to be used and the marginal cost is increasing. Often, marginal benefits are reduced as environmental security increases.
As the amount of protection for the environment rises to, the marginal costs outweigh the marginal benefits. Society is not allocating resources effectively at this stage of environmental security, since so many resources are giving up to reduce emissions.
As the scope of the environmental regulation grows, additional environmental spending will likely result in increased marginal costs.
Hence, marginal analysis is a specific tool used to way the cost of benefit versus cleanup in the environment.
Cellular respiration is the consumption of oxygen by a cell within a living organism.<span> In plant seeds, the cellular respiration does not occur until the seed has absorbed moisture and released stored starches that can then be metabolized into energy for the purpose of growth</span>
