Answer:
The patient with liver damage will make a full recovery because it is a gland. Glandular epithelium are under the epithelial tissue classification, and a characteristic of epithelial cells is that they quickly regenerate with lots of nourishment.
Explanation:
These chromatids are divided during anaphase and attracted to the opposite poles of the cell. This division produces 92 distinct chromatids in the cell, which are regarded as 92 chromosomes.
In the cell at anaphase 1, how many chromosomes are there?
chromosomes with 46 in total. From from point on, we will refer to these divided sister chromatids as daughter chromosomes. Each end of the cell has an identical and full set of 46 chromosomes, or 23 pairs of homologous chromosomes, at the end of anaphase; they are still diploid.
Metaphase 1 has how many chromosomes?
chromosomes with 46 in total. In metaphase I, there are a total of 46 chromosomes, each of which is made up of two sister chromatids. There are 23 homologous pairs with two full chromosomes in each. throughout telophase I.

Answer:
When a doctor strikes the child's kneecap:
- <em>The </em><em>sensory receptors </em><em>located in the tendon receive the stimulus.</em>
- <em>Information travels by </em><em>afferent pathway </em><em>through the sensory component of </em><em>motor nerve</em>
- <em>The integration center, in the </em><em>spinal cord</em><em>, receives the information and sends a motor response by </em><em>efferent pathway</em><em>.</em>
- <em>The </em><em>quadriceps contracts and extends the leg</em><em>.</em>
Explanation:
The patellar reflex —by hitting the kneecap tendon—is an example of a reflex arc, which produces the extension of the leg over the knee as an involuntary response to the stimulus to strike the patellar tendon.
This reflex has five main components:
- <em>Receptor.</em>
- <em>Sensitive fibers of a motor nerve (afferent pathway)</em>
- <em>Spinal cord integration center.</em>
- <em>Motor nerve fibers (efferent pathway).</em>
- <em>Effector.</em>
The reflex arc occurs because the stimulus received does not travel to the brain, but to the spinal cord, which causes the reflex response to be faster.
When the doctor strikes sensory neurons below the boy's kneecap, the following sequence of events occurs:
- The sensory receptors located in the tendon receive the stimulus.
- Information travels by afferent pathway through the sensory component of the femoral nerve.
- The integration center, in the spinal cord, receives theinformation and sends a motor response by efferent pathway.
- The quadriceps contracts and extends the leg.
The patellar reflex evaluates the integrality of the reflex arc at that level, whose synapse occurs between the lumbar segments of the spinal nerve L₂ and L₄.
