Answer:
Firstly matter is definite as anything that has a mass and occupies space. Does air has those qualities? Yes. air contains of molecules and makes up the mass component and have you ever try compressing air? From that you knowa it occurs space
So what must be true is that it must have mass and occupy space
Nucleotides can be radiolabeled before they are incorporated into newly forming DNA and, therefore, can be assayed to track their incorporation. In a set of experiments, a student-faculty research team used labeled T nucleotides to study the incorporation of labeled nucleotides into a culture of lymphocytes. They found that the lymphocytes incorporated the labeled nucleotide at a significantly higher level after a pathogen was introduced into the culture. they might conclude from this observation is that the Infection causes lymphocytes to divide more rapidly
- Lymphocytes is a type of immune cell produced in the bone marrow and present in the blood and lymphatic tissue. B lymphocytes and T lymphocytes are the two main types of lymphocytes. T lymphocytes help eliminate tumour cells and govern immune responses, whereas B lymphocytes produce antibodies. A lymphocyte is a white blood cell type.

You can see the location of the appendages on the segments more clearly on the ventral side of the crayfish.
Explanation:
Answer:
a. Type O blood - No A or B antigens on RBCs-Anti-A antibodies in plasma-Anti-B antibodies in plasma
b. Type A blood - A antigen on RBCs- Anti-B antibodies in plasma
c. Type B blood - B antigen on RBCs- Anti-A antibodies in plasma
d. Type AB blood - A antigen on RBCs- B antigen on RBCs- Neither anti-A or anti-B in plasma
Explanation:
ABO blood grouping system represents multiple allelism which was discovered in humans by Karl Landsteiner. The blood group is determined by the presence or absence of A & B antigens and antibodies.
The 4 blood groups which exist in ABO system are O, A, B and AB. Also, allele A and B are co-dominant i.e. if they both will exist on the surface of an RBC then both will be equally expressed which implies that there will be no dominant or recessive allele.
Type O blood group has H antigen on the surface of RBC and has both the antibodies i.e. antibody A and B. The absence of antigens A and B makes it a universal donor.
Type A blood group has A antigen on RBC and has antibody B in the plasma.
Type B blood group has B antigen on RBC and has antibody A in the plasma.
Type AB blood group has both the antigens i.e. antigen A and B on RBC and does not have any antibody in the plasma which makes it a universal acceptor.
