-
Infect a host cell and use the cell's ribosomes, enzymes, ATP, and other components
Correct Answer
A. Infect a host cell and use the cell's ribosomes, enzymes, ATP, and other componentsExplanation
To replicate, a virus must infect a host cell and utilize the cell's ribosomes, enzymes, ATP, and other components. This is because viruses are obligate intracellular parasites that lack the necessary machinery to replicate on their own. They rely on host cells to provide the necessary resources for replication. By infecting a host cell, the virus can hijack the cell's machinery and utilize its ribosomes, enzymes, ATP, and other components to produce new viral particles. This allows the virus to replicate and spread within the host's body.Rate this question:

Correct Answer
A. The feeding position of an organism in a food chain or web.Explanation
A trophic level refers to the feeding position of an organism in a food chain or web. It represents the hierarchical levels in an ecosystem where organisms obtain energy and nutrients. Each level represents a different group of organisms that occupy a specific position in the food chain. Organisms at higher trophic levels consume those at lower levels, indicating the flow of energy and nutrients through the ecosystem. This concept is crucial in understanding the dynamics and interactions within an ecosystem.Rate this question:

Sexual reproduction
-
The conditions in the environment.
-
How many siblings are available to gang up on the parents.
Correct Answer
A. How many species either benefit or are harmed.Explanation
The main difference among the types of symbiotic relationships is how many species either benefit or are harmed. This means that in different types of symbiotic relationships, the number of species that are either benefiting or being harmed varies. This distinction is important because it helps us understand the dynamics and interactions between different species in a symbiotic relationship. It allows us to categorize the relationships based on the impact they have on the involved species, whether it is mutualistic, where both species benefit, parasitic, where one species benefits at the expense of the other, or commensalistic, where one species benefits without harming the other.Rate this question:
