Biological control methods for managing insect pests are effective for reasons that include which of the following? They promote
genetic resistance in the target species, resulting in a population explosion of the target species. They generally focus on one target insect to ensure that the target insect population remains low. They can lead to a self-perpetuating population of a control species.
Option B, They generally focus on one target insect to ensure that the target insect population remains low.
Explanation:
Biological pest control methodologies are focused towards a specific species of pest and do not harm the non-targeted species. These methods are environment friendly and do not produce any harmful residues. Also they do not develop any kind of resistance in species due to which the same bio pesticide can be used again and again. Since these methods have high specificity, they may require usage of two or more bio pesticides all together.
The single celled protists which is one of the example of
this is the paramecia survives and lives on extreme hypotonic environment. They
have the ability of having to contract their vacuoles in which this contributes
and help them to live and survive in a hypotonic environment.
C and D are the answers. A is incorrect because of asexual reproduction. B is incorrect due to it have the same number. E is not correct because meiosis is sexual reproduction.
