Answer:
B. Oxygen molecules recombine to allow cells to get larger
There exists the same question with the following choices.
1.Meiosis produces eggs and sperm that are alike.
<span>2.Meiosis provides for chromosomal variation in the gametes produced by an organism. </span>
<span>3.Equal numbers of eggs and sperm are produced by meiosis. </span>
<span>4.The gametes produced by meiosis ensure the continuation of any particular species by asexual reproduction.
</span>
The correct answer is <span>2. Meiosis provides for chromosomal variation in the gametes produced by an organism. It happened during cross-over and segregation and law of independent assortment.</span>
Gene duplication, mutation, or other processes can produce new genes and alleles and increase genetic variation. New genetic variation can be created within generations in a population, so a population with rapid reproduction rates will probably have high genetic variation.
Answer: Resource partitioning
Explanation:
In order to make organisms of different species (competitors) coexist, limited resources are to be divided with a ecological area.
Organisms of same species could be made to live together, so as to reduce wastage of limited resources
Answer:
antibiotic resistant is a consequence of evolution via natural selection. the antibiotic action is an environmental pressure;those bacteria which have a mutation allowing them to survive will live on to reproduce
