Answer: Pretty much every aspect of them
Explanation:
Stem cells have unique regenerative abilities which can be used for treating diseases and disabilities (from diabetes to MS). They can also be used to graph skin from burns etc. The stem cell science world seems to leave so many options open for discoveries and they have less negative side effects in comparison to the chemical treatments available or soon to become available. Stem cells can heal rather than pharma therapies covering the ailment and leading to other issues.
Answer: The Golgi apparatus.
Explanation: I believe it is the Golgi apparatus as the Rough ER and Smooth ER create proteins and sort them in to piles before sending to the Golgi apparatus to deliver.
The Smooth ER and Rough ER are like the suppliers while the Golgi apparatus is like the transporter.
Remember: Proteins have many functions and are needed severely to perform those actions that without the Golgi apparatus, those proteins wouldn’t be able to be transported.
1) Speed = distance / time
s = 60 / 2
s = 30 km/h
In short, Your Answer would be Option B
2) Speed = distance / time
s = 25/4
s = 6.25 km/h
In short, Your Answer would be Option B
[ Direction not needed as it is speed not velocity ]
Hope this helps!
