Hydrogen bonds.
The nucleotides in a base pair are complementary which means their shape allows them to bond together with hydrogen bonds. The A-T pair forms two hydrogen bonds. The C-G pair forms three. The hydrogen bonding between complementary bases holds the two strands of DNA together
Answer:
In mathematics it is used for dividing a number, whereas in science it is element which helps in proving certain effects. So they are different for different subject.
Explanation:
In mathematics factor is to break or divide in to numbers which can be further multiplied to get the actual number. Example 6 = 3 
2. here 2 and 3 are factors of 6. But when it comes to science factors are the elements that contributes something to result. It may be in controlled environment or naturally occurring one. The lab experiments are basically done in the controlled environment to check the factor effect over the experiment.
A, b, and c! i’m sorry if you get this incorrect but i’m sure that it’s right
The sorting of genes during sexual reproduction results in a large amount of genetic variation.because the primary advantage sexual reproduction has against asexual reproduction because of genetic diversity
B is the right option
hope this helps
