The correct answer is option a, that is, 3000 cases. 
Explanation:
The measurement of all the individuals getting influenced by the disease at a specific time is known as the prevalence. On the other hand, the measurement of the number of novel individuals that came into contact with a disease during a specific time duration is known as the incidence.  
Based on the given question, the number of prevailing cases carried from 2018 to 2019 is 2000, and the new diseases recorded in the year 2019 is 1000 (incidence). Therefore, the prevalence of the disease in 2020 will be 3000 cases.

Hard water contains mineral ions basically the calcium and magnesium ions.
The presence of hard water often considered a negative thing as it is associated with a number of issues related to plumbing, water storage as well as cleaning and maintenance.
Hard water leads to clogged pipes due to the deposition of ions on the surface of water conducting pipes. This hindrance also degrades the quality of equipment used for water storage and heating e.g. geysers.
The hardness of water can either be temporary or permanent depending on the type of ions present in it. Temporary hard water contains calcium and magnesium ions whereas Permanent hard water contains anions like the sulfate ion.

Answer: The answer is C, a monohybrid cross.
Explanation: 
A dihybrid cross would be crossing 2 (usually linked) traits in the same punnett square, while a trihybrid cross is with 3 traits. Since he's only studying 1 trait (tall vs. short) the answer is C, a monohybrid cross.
