Answer: The answer is D
Explanation: Bed bugs do in fact release an anesthetic as they feed to increase blood flow the the bite that makes it quick and painless to the victim until later.
There are not only one but two correct option, which are A and B.
DNA polymerases begin their synthesis at many points of initiation. Following the binding of specific proteins, the double helix opens to allow startup.
DNA synthesis begins on RNA / DNA primers consisting of primase and DNA polymerase a. The replication continues in one direction: in this sense one of the two strands of the DNA ("direct" strand) is traversed by the enzyme in the 3 '→ 5' direction, which allows the synthesis of another strand in the direction 5 '→ 3'. The DNA-ligases then provide the link between the different fragments of the new DNA.
The synthesis of the other strand ("delayed" strand) is more complex because the enzyme travels this strand from 5 '→ 3'. The primase and DNA polymerase α synthesize 30 nucleotide primers in front of the replication zone, and the DNA polymerase constructs small DNA fragments in the 5 '→ 3' direction (approximately 200 nucleotides; Okazaki). Ribonucleases destroy the RNA / DNA primers of the previous fragment and the fragments are then linked together by DNA ligase.
<span>Molecular clock is a scale which uses a technique whereby evolutionary time for different life forms is deduced from the mutation rate of biomolecules. Biomolecular data used for calculations in order to come up with the prehistoric time scale normally uses nucleotide sequences for DNA or amino acid sequences for proteins.
Hence, in order to develop a molecular clock, one would need: a sequence of molecules, the rate at which changes occur in a type of molecule and how much total change has occurred in a type of molecule from different species.</span>
Answer:
Smaller muscle groups with a similar functional ability might include the antagonist major which acts as synergist in producing the same action as the agonist.
example : the biceps and triceps muscles of arm, work together as agonist and antagonist respectively.
The biceps helps to lift up or flexes the forearm and the triceps helps to extend it.
Explanation:
many muscles work together to make an action happen.
the muscle who is involved in an action principally, is known as prime mover or Agonist muscle.
Antagonist muscle does the opposite action of the agonist muscle.
antagonist also helps in-
- maintaining the body posture or position.
- controls the rapid movements.
like, to move a bone , the muscles attached to it work together to make a movement happen. like- to lift up a arm, agonist or prime mover muscles helps to lift up or flex the arm and the antagonist or synergist muscle helps to extend it.
