B - sponges.
Sponges can regenerate but can’t reproduce through regeneration
That would be beneficial to them because they wouldn't lose as many trees to disease or insects, so they are able to sell more.

Obsidian is a volcanic glass. It is produced when magma from volcanoes is cooled and solidifies rapidly, before there is time for crystals to grow. It is usually black in color. It shatters like glass and makes excellent axe and arrow heads and the main mineral in it is quartz (silica).
Bedrock is the solid rock that lies underneath the soil in broken, weathered rock. It is not found beneath anything in particular, it simply lies below the loose weathered material on the surface. Bedrock may be many different types of rock that extend for kilometers down into the earth's crust.
Answer:
B) aorta to smaller systemic arteries to systemic capillaries to systemic veins to right atrium through the triscupid valve
Explanation:
Oxygenated blood from the right ventricle is pumped into the aorta. Aorta is the largest systemic artery that obtains oxygenated blood directly from the heart. Many systemic arteries get oxygenated blood from the aorta. Exchange of oxygen between blood and tissue cells occurs in systemic capillaries.
The deoxygenated blood from tissues is picked by systemic veins. The deoxygenated blood from systemic veins is delivered to the right atrium via vena cava. The blood is pumped from the right atrium to the right ventricle through the tricuspid valve from where it is carried to the lungs for oxygenation. The oxygenated blood from the left atrium is pumped to the left ventricle and finally into the aorta.
