The primary function of all lymph nodes is the production of lymphocytes, which help defend the body against microorganisms and against harmful foreign particles and debris from lymph before it is returned to the blood stream. The major clusters of lymph nodes are in six areas.
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.
Answer:
Fossil fuels
Explanation:
The definition of "fossil fuel" is "a natural fuel such as coal or gas, formed in the geological past from the remains of living organisms"
Answer:
The correct answer is Smooth ER: protein synthesis
Explanation:
Endoplasmic reticulum is a single membrane-bound organelle containing interconnected membrane-bound cisternae which are the extension of the nuclear membrane. Endoplasmic reticulum is divided into two parts smooth endoplasmic reticulum and rough endoplasmic reticulum.
Smooth endoplasmic reticulum does not contain ribosomes on it and is involved in the synthesis of steroid hormones and lipids, detoxification of harmful products and removal of xenobiotic from the cell, calcium storage, and metabolism.
Rough endoplasmic reticulum has ribosomes on its surface which helps in protein synthesis on RER. So Smooth ER and protein synthesis are incorrectly matched.
