Avariety of different mechanisms in nature create diversity in organism populations. the tundra found in the northernmost parts of the planet is the world’s youngest biome. the tundra is home to a variety of plants and animals. organisms that can be found in the tundra include shrubs, mosses, caribou, polar bears, and wolves. which mechanism do the different organism populations found across the tundra exemplify?

1. genetic diversity
2. ecosystem diversity
3. species diversity
4. variation

In the Tundra region, the diversity of the organisms present is high. Multiple different species of different organisms are present in these regions, which makes them a diverse area on the Earth. The mechanism responsible for these different populations is the species diversity.

It can be defined as the total number of species that are present in a given community.

Hence, the correct answer is option 3.

cuz he is really really short, assuming an unorthodox and inherently unlucky configuration of elevator buttons…

explanation:

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.
