Question

a. they leave contamination everywhere they go
b. they are weak and easy to handle
c. they breed slowly and in small numbers
d. they cannot detect odours

Answer 1

The true statement about rodents from the given options is that they leave contamination everywhere they go, such as droppings and urine, which can spread diseases.

Step-by-step explanation:

Among the provided options, the statement that is true of rodents is: a. they leave contamination everywhere they go. Rodents, such as rats, are known for leaving droppings and urine as they travel, which can contaminate food sources and living environments. This can be particularly concerning when it comes to the spread of diseases like plague, which rodents have historically been vectors for. Furthermore, rodents are typically prolific breeders and can have large numbers of offspring, making their potential to spread contamination even greater. They also have a robust olfactory sense, making the option that rodents cannot detect odors incorrect.
