Question 1
Answer is E
The homeostasis in body can be maitained by positive and negative feedback mechanisms.nIn positive feedback the end products of an action cause more action to occur.
child birth, blood coagulation and coplementary activation are positive feedback mechanisms.
Question 2
Answer is C
long range interactions occured in the 3-D Folding of a single polypeptide chain it give the complexicity to hemoglobine.
Question 3
The answeer is B
Chylomicrons and very low density lipoprotein (VLDL) are the main TG carriers among other types of lipoproteins.
Low-density lipoproteins and high-density lipoproteins are involved in cholesterol transportation.
Chylomicrons carry Triglecerides from the intestine to extrahepatic tissues.
The Very low density lipoproteins carry TG from the liver(hepatocytes) to extrahepatic tissues.
Question 4
Answer is D
DNA Polymerase III binds to Single stranded DNA. In DNA replication the double stranded DNA undergoes into separation by helicase. then the leading strand and logging strand. The DNA Polymerase III binds to leading strand and synthesize complementary nucleotides.
