Answer
Brief Explanations:
- For the first question, contagious diseases spread easily from one host to another. Sporadic diseases occur irregularly and infrequently, epidemic diseases are widespread in a population at a particular time, and endemic diseases are constantly present in a particular area.
- For the second question, due to the principle of inertia, when you toss a coin in a vehicle moving at a steady speed, the coin has the same horizontal velocity as the vehicle. So it will land back in your hand.
- For the third question, salt - curing meat works by removing water. Microbes need water for growth and metabolism, and by removing water, salt inhibits their growth.
