4. coevolution is when two species that have close ecological interactions evolve jointly over time.

No, coevolution never occurs when two species that have close ecological interactions evolve jointly over time.

Explanation:

The coevolution is the process in which two species evolves together. These species affects each other. In coevolution, species shares close ecological interactions.

The ecological relationship which shows coevolution are parasitism and competition, mutualism. In parasitism one species is negatively affected and the parasite gains the benefit. In competition both species harm each other.

In mutualism both species gains the benefit.

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."

answers are:

lysogenic     viral dna merges with host cell dna

lysogenic     no symptoms

lytic               viral dna takes over

lysogenic     virus does not destroy host cell

lytic               virus destroys host cell

lytic               induces symptoms of viral infection

lysogenic       cell reproduces and spreads provirus
