Stem cells are immature cells that do not have a specific function. What causes these cells to become specialized cells such as
blood cells? (A) Ribosomes are used to modify the DNA sequence.
B Certain genes are activated and cause a particular cell to develop.
Proteins made in the cell send glucose to signal the cells to develop.
D Enzymes cause chemical reactions to speed up and the cell to mature.
Stem cells become specialized cells such as blood cells because certain genes are activated and cause a particular cell to develop (Option B). It is called differentiation.
<h3>What is cellular differentiation?</h3>
Cellular differentiation refers to the process by which certain genes are expressed in a particular cell lineage.
Cellular differentiation leads to the formation of mature specialized cells that perform specific functions.
For example, immature hematopoietic stem cells become differentiated to produce mature red blood cells.
<em>Homothermy or homeothermy is thermoregulation</em> that keeps up a stable inner internal heat level paying little mind to outside impact
This inside internal heat level is regularly, however not really, higher than <em>the prompt condition </em>
The encompassing <em>temperatures increment,</em> <em>homeotherms </em>utilize evaporative cooling through perspiring as well as gasping to control internal heat levels, and also vasodilate surface <em>blood vessels to promote heat loss</em>
