Difference between a runner spitting versus just someone standing still
Explanation:
Runners while running do breathe, pant, and heave heavily which leads to spitting in the open as a habitual practice. This spitting while on motion leads to heavy dispersal of aerosol droplets which suspends in the air.
Droplets due to respiratory or spitting sources from any person who is infected with any infectious and contagious viral, bacterial, or other infectious diseases will have high chances of the pathogen present in them.
Further the rate and spread of droplet dispersal and transmission of pathogen will be higher compared to that from someone standing still. This puts greater potential for the spread of such droplet transmitted diseases.
Hence proper distancing should be maintained between runners and others to prevent spread of droplet transmitted diseases.

Which feature do prokaryotic and eukaryotic cells share?
Answer:
Nuclear envelop
Explanation:
Nuclear envelop is the double membrane structure that makes the boundary of the nucleus. It serves to protect the DNA from the toxins, wastes and other harmful substances produced during metabolic reactions of the cell occurring in cytoplasm.
If the nuclear envelope does not protect DNA, DNA could be damaged by free radicals or toxins. A cell with damaged DNA is subjected to death.
Answer:
The Nucleus.
Explanation:
The nucleus is surrounded by a membrane called the nuclear envelope, which protects the DNA.
