What happens when worms are exposed to too much light?
Correct Answer
C. They become paralyzed
Explanation
Exposure to excessive light can cause worms to become paralyzed. This is because worms are sensitive to light and prolonged exposure can disrupt their nervous system, leading to paralysis. When paralyzed, worms are unable to move or perform their usual functions. This can have detrimental effects on their survival and overall well-being.

A worm's digestive system can be likened to?
Correct Answer
B. A tube
Explanation
A worm's digestive system can be likened to a tube because it is a long, hollow structure that runs from the mouth to the anus, allowing food to pass through and be broken down and absorbed along the way. This comparison suggests that the digestive system of a worm is a simple, linear pathway for food digestion, similar to a tube.
5.
Which of the following is not true:
Correct Answer
C. Some worms like salt
Explanation
The statement "Some worms like salt" is not true because worms do not have taste buds and therefore do not have the ability to like or dislike any specific food or substance, including salt. Worms primarily feed on decaying organic matter and soil, and their diet does not include salt.
6.

7.
Worms are in everywhere except:
Correct Answer
B. Antarctica

Worms are found in various habitats around the world, including Africa, Europe, and Asia. However, they are not found in Antarctica, as the extreme cold temperatures and lack of suitable soil make it inhospitable for worms to survive. Therefore, the correct answer is Antarctica.
8.
One of these is not a category of an earthworm?
Correct Answer
D. Elogeic
Explanation
The given options are categories of earthworms based on their habitat and behavior. Epigeic earthworms live in the upper layer of soil and feed on organic matter on the soil surface. Endogeic earthworms live in horizontal burrows in the soil and feed on soil and organic matter within it. Anecic earthworms create vertical burrows in the soil and feed on organic matter on the soil surface. However, "Elogeic" is not a recognized category of earthworms, making it the correct answer.

"Majority of the worms are earthworms" How true is this statement
Correct Answer
A. Very True
Explanation
The statement "Majority of the worms are earthworms" is very true. Earthworms are the most common and abundant type of worms found on Earth. They are found in almost every part of the world, except in extreme environments such as deserts and polar regions. Earthworms play a crucial role in maintaining soil health and fertility by decomposing organic matter and improving soil structure. They are also an important food source for many animals. Therefore, considering their widespread distribution and ecological significance, it can be confidently stated that the majority of worms are indeed earthworms.
