As you can see in the table presented below, in the first few years after the eruption, there was a significant number of moss species present.
Pioneer species are species that are very resilient and first to inhabit new habitats or repopulate disrupted ones, so in this example, mosses are the most likely candidate for pioneer species.
Answer:
A community refers to all the populations in an area; an ecosystem includes both biotic and abiotic components.

Answer:
Pulmonary circulation only occurs between the heart and the lungs. Systemic circulation refers to the circulation of blood in which oxygenated blood is pumped from the heart to the body and deoxygenated blood is returned back to the heart. Systemic circulation occurs between the heart and the entire body.
Pulmonary circulation moves blood between the heart and the lungs. It transports deoxygenated blood to the lungs to absorb oxygen and release carbon dioxide. The oxygenated blood then flows back to the heart. Systemic circulation moves blood between the heart and the rest of the body.
Explanation:
Systemic circulation carries oxygenated blood from the left ventricle, through the arteries, to the capillaries in the tissues of the body. From the tissue capillaries, the deoxygenated blood returns through a system of veins to the right atrium of the heart.
The answer is D, dry and hot. The eastern side of the Sierra Nevada mountains is also known as Death Valley.
Answer:
c) Human blood cells are larger than Bacillus subtilis.
Explanation:
Eukaryotes are typically much larger than prokaryotes. Prokaryotes vary in size from cells as small as about 0<u>.2 mm in diameter to those more than 700 mm in diameter</u>.
<em>Bacillus subtilis</em>, which are rod-shaped, are 4–10 micrometers (μm) long and 0.25–1.0 μm in diameter.
<em>Staphylococcus aureus, </em>which are spheres, are up to 1 μm in diameter.
Yeast cells are typically much larger than bacterial cells and can be distinguished from bacteria microscopically by their larger size. A single cell of <em>Saccharomyces cerevisiae</em> is about 6 μm in diameter.
On the other hand, red blood cells have a diameter of 6 - 8 μm.
