B) Diploid - Only Gametes are Haploid. Every other cells are somatic cells which are diploid. They contain 46 chromosomes rather than 23 that the haploid carry. Neurons and glial cells make up of the brain and that makes up the nervous tissue. Just remember Gametes (sex cells) are the only cells that are haploids.
Answer:
O: Type O individuals can donate blood to anyone, because their blood has no antigens. However, they can only receive blood from other type O individuals (because blood with any antigens is seen as foreign).
Answer:
<h2>They provide a 3’ end for the DNA polymerase.</h2>
Explanation:
Polymerase chain reaction (PCR) is an in-vitro method to making copies of a specific DNA sample in a very short time.
Polymerase chain reaction was invented by Kary Mullis in 1983.
Primers are specific to the DNA which we want to replicate and they bind to the specific sequence which is complementary to it. Primers provide a 3’ end for the DNA polymerase.
Their roots are near the surface, where they have access to oxygen.
