Answer: Option A and B.
Organ system and tissues.
Explanation:
Earthworm is a segmented worm that belong to the phylum annelids. Earthworm has a close circulatory system just as human beings which means their blood circulate through a closed network of vessels which are connective tissues. Earthworm has a structure of 5 hearts and they are called aortic arches which are organ systems. These pump blood into network of vessels and it's flow through the body. From there, the blood move to dorsal blood vessel which send blood to the front of the Earthworm, then to the ventral blood vessel which send blood to the posterior. At the intestines, there are lateral vessels which carry nutrients away from the gut and to the body.
Answer:
5 Facts
Explanation:
1. When it comes to chemical weathering, it’s all about chemistry. By looking at the term “chemical weathering,” you can see that a chemical reaction causes something to break down or “weather.” That “something” is rocks and minerals.
2. In chemical weathering, rocks and minerals are reacting to acids, oxygen, carbon and water. That’s why no two rocks ever look exactly the same. It’s also the reason that we have those awesome looking caves and unique rock formations all over the world.
3. While chemical weathering creates nifty formations, the way it breaks down rocks also causes fractures in ancient structures like the Great Sphinx of Egypt. It also causes the surface to break down on gravestones.
4. Chemical weathering types can work separately, but they often work together to create landforms and break down minerals.
5. Acid rain caused by pollution such as factory and car exhaust is another agent of chemical weathering.
A point mutation or substitution is a genetic mutation where a single nucleotide base is changed, inserted or deleted from a sequence of DNA or RNA. Point mutations have a variety of effects on the downstream protein product—consequences that are moderately predictable based upon the specifics of the mutation.
