Answer:

<u>From the main motor cortex, Brodmann region 4 premotor areas and the primary somatosensory cortex .</u>

<u />

Explanation:

The corticospinal tract originates in many regions of the brain, including

  • the motor regions,
  • main somatosensory cortex
  • pre-motor regions

The corticospinal tract allows for voluntary control of motor functions.

30% of the neurons in the corticospinal regions are found in the primary motor cortex. 40% are split up in several regions; the parietal lobe, somatosensory cortex and the cingulate gyrus.

The axon is a tube enclosed in and insulated by the myelin sheath. It serves as a link to impulses for certain neurons that often comprise axon hillocks that are junctions between the axon and the cell body.

Which is correct about dna replication? dna polymerase can build dna from scratch. dna polymerase adds nucleotides in the 3' to
Ivahew [28]

The correct answer is: C) the place where the parent DNA becomes unzipped during DNA replication is called the replication fork.


DNA Polymerase doesn't build DNA from scratch, rather it adds the correct nucleotides to the complementary parent strand.


DNA Polymerase adds nucleotides in the 5' to 3' direction, not the 3' to 5' direction.


DNA is made semiconservatively, meaning that there is a template strand from the parent DNA with a complementary strand being the new daughter strand.


The strand that is made continuously is the leading strand. The lagging strand is not made continuously, as it requires the use of Okazaki fragments.

A cell has a surface area of 32 and a volume of 8 find the surface to volume ratio of the cell that is predicted to change
mina [271]
When we divide the surface area by the volume, we get the surface area to volume ratio:
     surface to volume ratio = surface area/volume = 32/8 = 4This ratio indicates how much exposure the cell has to the environment which is important in cells in regard to the transport, absorption, or secretion of materials.
