Answer:

c) degree of myelination of the axon

Explanation:

The myelin sheath covers many axons in central nervous system (CNS) ( by oligodendrocytes) and in the peripheral nervous system (PNS) (by Schwann cells). Their function is to insulate axons and to increase the speed at which information travels from one nerve cell to another.

Nerve conduction velocity is specific to each individual and depend on the level to which that axon is myelinated, but also on  an axon's diameter.

Why do hens scream in the morning ?
aev [14]
<h2>♨ANSWER♥</h2>

Chickens are vocal creatures, and if you're a chicken keeper, you might notice that your flock is particularly noisy in the morning. Chickens can make noise in the morning for a few reasons, including; they want to get out of the coop for food and water, they've laid an egg, or because they're vocalizing to each other.

Sever21 [200]

Answer:

DNA replication is the process by that DNA make a copy to the cell division.

Explanation:

  • DNA replication is the double structure to the DNA molecule,it is biological process.
  • DNA replication molecule the serve that template for the production to referred conservative replication.
  • DNA replication occurs living the biological property of division and they performed complementary stand.
  • DNA replication to that begin the specific location and origins in the genome, and growing from the origin.
  • DNA replication is performed to the outside and artificially to the cell,in the DNA molecule.
  • DNA replication is single strand by the DNA chain of nucleotide function, DNA contain the sugar .
  • DNA replication is the basis of single strand to 3 prime and 5 prime  end, these refer to the carbon atom in the chain attaches.
  • DNA replication allow the strand to the one another strand to used in partner strand.
  • DNA replication is to matched in the template strand at one time with the creation of bonds,they high energy bonds.
