Answer:
Option: B+
Explanation:
The test to determine a blood group is called ABO typing. The blood sample is mixed with antibodies against type A and B blood. Then, the sample is checked whether or not the blood cells stick together. If blood cells stick together, it means the blood reacted with one of the antibodies.
B+ blood group:
A blood sample that has only antigen B on the red blood cells and antibody A in the plasma lies under B+ blood group.
B+ blood type means the person has antigen B and rhesus factor on RBC and could be able to receive blood from another B+ donor.
Please note:
As only antigen B is mentioned that is why we will consider B+ BLOOD group. Because negative antigen is not mentioned in the question and when there is no sign is mentioned we will consider it positive.
It occurs in the DNA of a person. It's usually there at birth.
Answer:
A) The two strands of a DNA molecule are parallel and complementary.
Explanation:
DNA is a polymer of nucleotide and this nucleotide are made up of a deoxyribose sugar molecule, a nitrogenous base, and a phosphate group. In DNA genetic information of the cell is stored in the form of nitrogenous bases.
DNA is double-stranded and both the strands run anti-parallel with each other. This anti-parallel orientation provides the nitrogenous base of one strand to form hydrogen bonds with the nitrogenous base present on the opposite strand.
In DNA adenine base pairs with thymine with two hydrogen bonds and guanine base pairs with cytosine with three hydrogen bonds. So the false statement is A.
