Answer:
''Stem cells makes copies of itself whereas differentiated cells can't.''
Explanation:
stem cells function differently from differentiated cells because the stem cells divide and make copies of itself. It has the potential either to remain a stem cell or become another type of cell such as a muscle cell, a red blood cell, or a brain cell if the body needed while on the other hand, differentiated cells are specialized cells which performs specific functions and unable to divide.
It helps the cell by making sure everything gets circulated throughout the cell
Elderly people are most at risk
from minor trauma that results in serious spinal cord injury because of
preexisting degenerative vertebral disorders. Males are more prone to spinal
cord injuries than females but not as a result of preexisting disorder. This
may be related to an increased involvement in contact sports or a propensity to
participate in high risk activities. Neither females nor infants are at any
particular risk for spinal cord injuries.
<h3><u>Answer;</u></h3>
The above statement is <u>False </u>
<h3><u>Explanation;</u></h3>
- Speciation is an evolutionary process in which new species arise. There are three types of speciation, namely; sympatric, parapatric and allopatric speciation.
- <em><u>Sympatric speciation is a pattern in which speciation occurs in the absence of a physical barrier to gene flow; ex. polyploidy arising in flowers.</u></em>
- In an Allopatric speciation on the other hand, a physical barrier arises and separates two populations, ending gene flow between them and allowing reproductive isolating mechanisms to evolve so that later if the two groups come back into contact they will no longer be able to reproduce together, therefore making them different species.
