Answer:
A. The lytic lifecycle allows viruses to reproduce more quickly but also kills the host and forces the virus to find a new host cell.
Explanation:
The lytic lifestyle of the viruses (e.g. bacteriophage) can be described through the next steps:
- attachment and injection into the host cell (e.g.bacterial cell)
- synthesis of the early virus proteins which break down host's DNA
- virus uses host's machinery (for the replication, transcription and translation) to produce the rest of its proteins and to form new virus particles.
- host cell burst and many new virus particles are released.
During the lysogenic cycle, virus does not kill the host. It integrated its DNA into host's genome and stays dormant until conditions are optimal for reproduction.
Answer:
4. Habitat Isolation
Explanation:
Habitat isolation is a type of prezygotic reproductive barrier or isolation that occurs when two similar populations that can interbreed successfully are prevented from mating with each other as a result of being isolated by habitat. That is, they occupy different habitats. This is what keeps these frogs recognizably distinct.
Wildlife managers should investigate the current population of deer in the area and if there are other options and solutions for the problem, such as relocation of the deer.
