Explanation:
John Dalton proposed the theory of matter which is popularly known as the Dalton's atomic theory. In the atomic theory, Dalton identified from his experiments on gases that every matter is made up of small indivisible particles called atoms. These atoms are the smallest fractions of a matter.
- All the atoms of an element are all alike.
- Compounds form from atoms by simple whole number combinations alone.
- Chemical combination of atoms involves the rearrangement of reactants.

The difference between the two diseases that could lead to the same basic reproduction number is : One disease has lower transmission rate and a longer recovery period than the other. ( B )
Basic reproduction number ( r0) represents the number of people who gets infected through an infected person, and for a disease to be highly infectious its ( r ) number will have to higher than 1. and The value of r0 is determined based on certain factors which are :
- The Infectious period
- contact rate and mode of transmission
Therefore for the two viral diseases to have the same basic reproduction number one of the disease will have a lower transmission rate and a longer recovery period than the other

I think it might be the third option but I’m not sure
Humans could start using different approaches. For example, fossil fuels are non-renewable resources and this is what most humans use to fuel car engines. However, have you ever heard of battery operated cars? This is a much better alternative to cars that run on gas because, there is not as many toxins that are released into the environment and it will reduce the consumption of fossil fuels that are only so limited. Also, solar panels are way better that running lights on coal, and here is why: Solar energy is a renewable resource and if coal ever runs out, then there will always be another light source. I hope you found this helpful!
