Specialized enzymes called _____ polymerases can bypass distortions in the DNA template but tend to introduce replication errors
Yuri [45]

Answer:

The correct answer is: translesion.

Explanation:

Also called DNA polymerase V, the translesion polymerase is responsible for the repair of the DNA in prokaryotes like Escherichia coli.

These special enzymes repair DNA lesion during DNA replication. If the enzyme fails, the damage in the DNA can lead to the death of the cell.

Replication in prokaryotes is much more prone to errors than replication in eukaryotes, one of the reasons being this polymerase not being as effective as the polymerase in charge of repairing eukaryotic DNA, the DNA polymerase beta.

This type of air pressure is associated with warm air rising
tresset_1 [31]

Answer:

Areas where the air is warmed often have lower pressure because the warm air rises. These areas are called low pressure systems. Places where the air pressure is high, are called high pressure systems. A low pressure system has lower pressure at its center than the areas around it.

Identical population-splitting events occurred simultaneously on two neighboring islands, Islands B and C, which are each initia
sweet-ann [11.9K]

Answer:

This is due to the event of Speciation that happened for the rodents in Island B but not for the rodents in Island C.

Explanation:

  • Due to splitting of the population,
  • The sub-population of rodents formed in Island B are B1 and B2.
  • The sub-population of rodents formed in Island C are C1 and C2.
  • In case of Island B, each of the B1 and B2 sub-populations that got split from each other developed certain mutations that were necessary for them to adapt to the particular diverse environment each of them were exposed to, through the period of 50,000 years. These mutations were so varied that reproductive isolation was generated between them that resulted in each of them to develop into different species.Hence, speciation happens here and B1 and B2 are incapable of inter-breeding.
  • In case of Island C, each of the C1 and C2 sub-populations that got split might have got exposed to similar environmental change or no environmental change or the environmental change might have been too small to cause drastic change in each of the sub-populations. As a result of this the two sub-populations might have acquired certain mutations to adapt to the environment each of them were exposed to, through a period of 100,000 years. These mutations might not have been too variable or contrasting to cause reproductive isolation between C1 and C2. Hence, no new speciation happens here and C1 and C2 are capable of inter-breeding.

Explain why the ratio of motor neurons to muscle fibers is greater in muscles that control eye movement than in postural muscles
EleoNora [17]

Answer:

The muscles of the eye cover a greater number and in turn carry out greater fine motor skills.

Explanation:

Alpha motor neurons are neurons that invent the skeletal muscle, that is, striated, so that through the motor plate that is the unit that unites them, an action potential is transmitted that contracts the sarcomeros of the elastic fibers and the z lines. come closer, each eye movement is much more precise than the locomotion of the lower limb, which carries greater innervation in each muscle bundle due to the specificity of the movement, this is how more alpha motor neurons are required to mobilize the eye than a leg.
