Answer:
C) it is necessary for the survival of the individual.
Explanation:
Sexual reproduction is rarely, if ever, necessary for the individual. This is not a reason for its importance. However, while not important for the individual, sexual reproduction is important for the species. It allows genetic variability among offspring, as well as mutations. This ensures that not all members of a species are the same, and in this way, they have a better chance of surviving. Moreover, it allows for offspring to be produced at a faster rate.

Answer:
<em>The correct option is B. Alleles</em>
Explanation:
The punnet square can be described as a diagram which shows the outcomes of a cross. A punnet square will help us know what will be the probability for a particular trait to occur in the offsprings.
Genes might have the same or different alleles. If the alleles for a gene are similar in an organism, the organism is said to be homozygous for the trait. If the alleles are different, then the organism is termed as heterozygous.
A dominant allele is the one which which suppresses the effect of the recessive allele. A recessive allele gets masked by a dominant allele.
Answer:
DNA replication is the process by that DNA make a copy to the cell division.
Explanation:
- DNA replication is the double structure to the DNA molecule,it is biological process.
- DNA replication molecule the serve that template for the production to referred conservative replication.
- DNA replication occurs living the biological property of division and they performed complementary stand.
- DNA replication to that begin the specific location and origins in the genome, and growing from the origin.
- DNA replication is performed to the outside and artificially to the cell,in the DNA molecule.
- DNA replication is single strand by the DNA chain of nucleotide function, DNA contain the sugar .
- DNA replication is the basis of single strand to 3 prime and 5 prime end, these refer to the carbon atom in the chain attaches.
- DNA replication allow the strand to the one another strand to used in partner strand.
- DNA replication is to matched in the template strand at one time with the creation of bonds,they high energy bonds.
The answer is absorbing dead or decaying organisms
