Which hypothesis was most likely being tested in this investigation?
- A.
Plants grown in the dark cannot perform the process of respiration
- B.
Sunlight is necessary for the normal growth of bean plants
- C.
Light is necessary for the germination of bean seeds
- D.
Light is necessary for proper mineral absorption by plants
Correct Answer
B. Sunlight is necessary for the normal growth of bean plantsExplanation
The most likely hypothesis being tested in this investigation is that sunlight is necessary for the normal growth of bean plants. This is supported by the observation that the seedlings grown in the dark were white with long, slender stems and soon died, while the seedlings grown in sunlight were green and healthy. This suggests that the absence of sunlight negatively affected the growth and survival of the bean seedlings.Rate this question:

This Law states that "All layers of sediments are deposited in horizontal layers". This has been continuting for billions of years.
- A.
Law of horizontality
- B.
Law of superposition
- C.
Law of uniformitarianism
Correct Answer
A. Law of horizontalityExplanation
The Law of Horizontality states that all layers of sediments are deposited in horizontal layers. This means that when new layers of sediment are formed, they are generally deposited on top of older layers, creating a horizontal sequence of rock layers. This law is based on the observation that sedimentary rocks often exhibit distinct layers that are parallel to the Earth's surface. It is a fundamental principle in geology and is used to interpret the relative ages of rock layers and the processes that have shaped the Earth's surface over time.Rate this question:
