bacteria are classified as microbes
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.

Answer - The polarity of the water molecule helps it to cohere to nearby water molecule. Forming a skin over.
Reasoning - Since the polarity is all close and wanting to bond they have a surface tension which come together to making a skin like over.
Mutations are the source of all new alleles. An allele is a variant form of a gene. Variations in alleles lead to variations in organisms. Positive mutations give an organism a better chance of survival. It means that the mutation may be passed on to the offspring. Negative mutations may lead to an early death.<span> Therefore, changes in alleles from one generation to another form the basis of evolution.</span>
