Is this cell haploid or diploid? How can you tell?

The cell shown in the image is haploid, which can be affirmed by the presence of an odd number of chromosomes.

Explanation:

Haploid cells are those that have a single set of chromosomes, that is, half of the chromosomal charge (n) of an organism. These cells correspond to gametes.

Diploid cells are those with complete chromosomal charge (2n) and correspond to somatic cells.

The cell shown in the image is a haploid cell, since it has only three chromosomes. Because diploid cells contain chromosomes in pairs, even if the haploid cell of that species is odd or pair, diploids will always have an pair number of chromosomes.

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.

clumped distribution, because you'de have all of the population gathered in a relatively small are.

it's the most common because it provides protection and a mate for reproduction

example: humans, seeweed, cattles, etc.
