Can the change in cyclin concentration during mitosis be explained by the fact that the cell divides in two and thus divides the

material in the cell into two smaller volumes
Biology

Answer:

No, because cell division is expected to decrease not only the net amount of cyclin molecules in daughter cells but also the volume of these daughter cells compared to the original parent cell, and therefore the concentration should be nearly equal.

Explanation:

When a cell divides to produce two daughter cells, the cell components including its previously duplicated genetic material (DNA), organelles, signaling molecules, fatty acids (lipids), proteins, etc., are distributed into daughter cells. These daughter cells have a smaller volume compared to the original parent cell. In consequence, the concentration of cellular components (including cyclin proteins) should be similar between parent cell and daughter cells.

TRUE. A disease that wiped out a rabbit population in an environment would affect the coyote population in the same environment.

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.
