Answer:
<em>C. The bird population moved into and adapted to many different environments on the Hawaiian Islands.</em>
Why:
<em>When a species </em><em>adapts</em><em> itself to new environments certain features will change, such as beak size, wing use, and even height, these are all changed depending on what the species does and needs to survive. These birds all changed food sources which made them have to adapt their beaks over time to new sources, and natural color to over generations camouflage themselves better from predators.</em>
<em>(Hope this was a good explanation.)</em>
These steps are characteristic of a diplontic life cycle, in which haploid gametes are produced.
Answer:
Option b. Lowering the pH to kill pathogenic bacteria is correct answer.
Explanation:
bacterial motors are sensitive to pH. By decreasing the pH bacterial motors stops working. This was identified in a new research. But, with the weak acids and a lower internal pH they slow and ultimately stop moving (became dead).

Answer:
3. B. no new mating partners are available
7. D. best adaptations
8. C. survive and reproduce
Explanation:
Carrying capacity refers to the maximum population size of a species/population in a particular habitat. The carrying capacity depends on abiotic (e.g., shelter, water) and biotic factors (e.g., food, presence of mates). According to the evolutionary theory, individuals better adapted to their environments are more likely to survive and reproduce (i.e., produce more offspring) than other members of the same species. These 'better adapted' individuals will have more chances to pass their 'beneficial alleles' to the next generation.
