Answer:
Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes . Meiosis also produces genetic variation by way of the process of recombination .
Explanation: Meiosis is important for three main reasons : it allows sexual reproduction of diploid organisms , it enables genetic diversity , and it aids the repair of genetic defects .

Answer: The hypothesis can be completed as-
If the type of food available changes, then the frequency of beak also changes.
Explanation-
Natural selection is a theory of evolution that was given by Charle's Darwin. According to this theory, organisms that are capable of adapting themselves ( that is having beneficial traits, which enhance their survival) in the changing environmental conditions survive and increase their number by means of reproduction.
According to the information given in this question, the type of food available is changing, which will result in the change in the frequency of bird beaks inhabiting that area. This would indicate their adaptation so as to survive under the changed food type, otherwise they will be unable to consume the food resources and will die out.
The answer is B I believe, They contain genetic material.
Hope this helped :)
The DNA replication is a biological process where two DNA strands where each of the strands is used a template to form a new strand. The question answered in discovering DNA replication is on how DN evolved. I hope it helps.
<span>The different types of immune response fall into two categories; innate (non adaptive) and adaptive immune responses.
