6 0

Answer:

Metaphase leads to anaphase, during which each chromosome's sister chromatids separate and move to opposite poles of the cell. ... More specifically, in the first part of anaphase — sometimes called anaphase A — the kinetochore microtubules shorten and draw the chromosomes toward the spindle poles.

Axons from higher brain centers form motor tracts that descend from the brain into the white matter of the spinal cord and then
Alchen [17]

Motor output that is gotten from the spinal cord to skeletal muscles involves somatic motor neurons of the anterior gray horn. Many somatic motor neurons are regulated by the brain. Axons from higher brain centers form motor tracts that descend from the brain into white matter of spinal cord and then synapse with somatic motor neurons either directly or indirectly by first synapsing with interneurons that in turn synapse with somatic motor neurons.

Sensory receptors is known to detect sensory stimulus.

Sensory neurons often convey sensory input by nerve impulses through their axons. Their axon often start from sensory receptors into the spinal nerve and into posterior root.

From posterior root, axons of sensory neurons have 3 different choices of paths.

  • Axons of sensory neurons does start into the white matter of the spinal cord and moves up to brain as part of sensory tract.

  • Axons of sensory neurons sometimes do moves into the posterior gray horn and synapse with interneurons that has its axons extend into the white mater of spinal cord and thereafter moves to brain as sensory tract.

  • Axons of sensory neurons oftens moves into the posterior gray horn and synapse with interneurons which the synapse with somatic motor neurons.

Axons that is gotten from spinal cord often synapse with other motor neurons in PNS.

What percentage of offspring from a cross between a homozygous type A parent with a heterozygous Type A parent is expected to co
snow_lady [41]

The correct answer is option B, 50%

Let us take the following case:

Genotype of heterozygous parent - (Aa)

Genotype of homozygous parent – (aa)

Allele I  - (Aa)

Allele II – (aa)

The cross between the two is shown below:

Aa  X aa

Aa, Aa, aa, aa

There are 50 % Aa, and 50 % aa allele.  

Thus, the allele I (Aa) is 50 %.
