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.

The event that was dated using the most valid and reliable source is millipede appears.
<h3>What is a reliable source?</h3>
In science, reliable sources include those that provide strong evidence to prove a hypothesis is false or true. The most common reliable sources in science are:
- Data that was collected from experiments using the scientific method.
- Observations that are consistent.
- Peer-reviewed articles about a phenomenon.
- Evidence such as specimens, fossils, rocks, etc.
Based on this, the event that was dated using the most valid and reliable resource is the millipede appearance because this event was dated using fossils, which are a type of reliable source in science. Moreover, other sources such as history books or green plants are not reliable.

Answer:
Muscular strength exercises build neuropathways to your brain, strengthening and building your muscle. Muscular endurance exercises work the muscle you already have. For example, weight lifting would be muscular strength because you're building muscle. Running would be muscular endurance because you're seeing how long those leg muscles can last. However, the two can also "intermix" and you usually do both at the same time.
The answer is option A hope it helps!
