Answer:
The number of protons determines an element's atomic number and is used to distinguish one element from another
Explanation:
Together, the number of protons and the number of neutrons determine an element's mass number.
Because carbon dioxide is the greenhouse gas emitted in the largest quantities, and methane is an even more potent greenhouse gas, monitoring carbon emissions is widely seen as crucial to any effort to reduce emissions and thereby slow climate change.
Answer:
All plant and animal organisms that float or move to a limited extent in water, carried by currents and waves are called plankton.

Answer:
Option A, pathogen A
Explanation:
ID50 is a way to measure the virulent efficiency of a pathogen. ID50 for a pathogen depicts the number of pathogens required to infect or cause the associated disease with in 50 percent of any population sample.
This means that 50 pathogens A can infect 50 percent of any sample population.
While 1000 pathogen B and 1000000 pathogen C are required to infect 50 percent of any sample population.
hence, Most virulent pathogen is Pathogen A
