Answer:
Gametes are what fuse together to make an organism. (Sperm cells)
Explanation:
Chromosomes split in half partly to create gametes.
Answer:
Evidence of evolutionary relationships include: similarities in body structure, fossils, protein structure, similarities in DNA, and similarities in early development. Know how fossils are formed, named, and how scientists determine fossil age. Most fossils form when organisms die and are buried in sediment.

Answer:
The correct answer is OPTION B (b. Yes—the initial infection might be acute but the virus can later become latent by becoming integrated into the host cell genome).
Explanation:
The hepatitis B virus has an unusual feature similar to retroviruses. This makes it deadly and difficult to treat when it is at an advanced stage. It basically attacks the liver and can cause both an acute and persistent infection.
In the acute stage, the cells are newly attacked and the body is fighting it off, the symptoms might start showing depending on how long it has invaded the body. These symptoms include dark urine, vomiting, yellowing of the skin and eyes (jaundice), the liver can still fail at this stage causing death.
At the persistent stage, which is already chronic, the invaded cells have been weakened, the symptoms are slow to resolve therefore it is in a prolonged stage which can lead to liver cancer and eventual death.
Answer:
B
Explanation:
The answer is B; there cannot be a large population in an ecosystem that only provides a small amount of food; similar to how a family of six cannot live off of the same amount of food that a single person could easily live off of. This concept rules out both A and D, and C is also incorrect because the ecosystem is independent of the population, it is not aware of the amount of organisms living it; so it cannot alter it's resources based off of what organisms live in it.
