Answer:
the relationships are probably mutual or parasitic
Explanation:
The argument of most scientists when it comes to commensalism is that the likelihood of a relationship between two different organisms, where one of the organisms to be completely unaffected is low. They propose that their relationship, although not obvious, is more likely to be mutualistic or parasitic at best.
Answer:
2. A change occurs in the environment.
4. Poorly adapted individuals have decreased survivorship.
1. Well-adapted individuals leave more offspring than do poorly adapted individuals.
3. Genetic frequencies within the population change.
Explanation:
The natural selection theory was developed by Darwin to explain how evolution occur within a population. The environment is in constant state of changes and always select for organisms that are better adapted to it.
Poorly adapted organisms gradually reduce from the population as a result of decreased survival while well-adapted individuals multiply and contribute more to successive generation.
Well-adapted individuals pass on the adaptive alleles to their offspring, eventually leading to a change in gene frequencies within the population.
Hence, the sequence of events is 2, 4, 1 and 3.
Answer:
Hard
Explanation:
it is hard because these are usually hard parts of an organism including shells, bones, teeth, woody trunk, stems, and branches.
