Answer:
Bacteriophages have a lytic or lysogenic cycle.
Explanation:
The lytic cycle leads to the death of the host, whereas the lysogenic cycle leads to integration of phage into the host genome. Bacteriophages inject DNA into the host cell, whereas animal viruses enter by endocytosis or membrane fusion.
Answer:
Examples of vestigial structures include the human appendix, the pelvic bone of a snake, and the wings of flightless birds. Vestigial structures can become detrimental, but in most cases these structures are harmless; however, these structures, like any other structure, require extra energy and are at risk for disease.

Answer:
advantages of sexual reproduction:
it produces variation in the offspring
the species can adapt to new environments due to variation, which gives them a survival advantage
a disease is less likely to affect all the individuals in a population
disadvantages of sexual reproduction:
time and energy are needed to find a mate
it is not possible for an isolated individual
advantages of asexual reproduction
the population can increase rapidly when the conditions are favourable
only one parent is needed
it is more time and energy efficient as you don't need a mate
Disadvantages of asexual reproduction
it does not lead to variation in a population
the species may only be suited to one habitat
disease may affect all the individuals in a population
Explanation:
The last option: over tens of millions of years, the giant supercontinent Pangaea began to slowly drift apart forming the continents
Answer:
Indohyus is a fossil, found in 2007, of a chevrotain-like mammal believed by some paleontologists in the Evil Liberal Science Conspiracy to be a transitional form between land-dwelling mammals and the ancestor of whales.
The origin of cetaceans from land-living mammals is among the most famous of these events. Much earlier, during the Mesozoic Era, many reptile groups also moved from land to wate
