B. A plant that produces seeds with protective covers
C. An ancestor of mollusks, worms, and arthropods
D. An ancestor of cnidarians, coeloms, and sponges
An angiosperm is a group of plants that produces seeds with protective covers.
Angiosperm is the group of a plant that produces flowers. It belongs to the group of flowering plants in plant species.
Hence, option B is the right answer.
To learn more about angiosperm, refer:

a plant that has flowers and produces seeds enclosed within a carpel. The angiosperms are a large group and include herbaceous plants, shrubs, grasses, and most trees.
Answer: B
The correct answer would be: rock cycle
Explanation taken from user Bistai
"The rock cycle is a recycling process by which igneous, metamorphic, and sedimentary rocks are produced, converted from one form to another and destroyed. The rock cycle is a continuous process that has been occurring throughout the history of the earth. The major processes of the rock cycle include sedimentation, crystallization, metamorphism and erosion."
Why is Amy’s question not a very good scientific question?
Answer:
She generalized it to living things when she was only observing plants.
When coming up with a scientific question it needs to be based on observation. As you see, what she was looking at were plants only. If she also observed this behavior with other living things, aside from plants and it needs to be several, it would be okay to generalize.

Earth rotates on an axis.
Earth revolves around the Sun.
The Moon rotates on an axis.
The Moon revolves around Earth.
Answer:
A
Explanation:
The Earth rotates on a tilted axis. Since the Earth also moves around the sun, one part of its face will be exposed the sun's light, while the other part will be in darkness.
Because the Earth spins, for a certain number of hours, one face will be exposed to the sun, so that's day. However, after spinning for a while, that face will then be turned away from the sun, and will experience darkness, which is night.
Thus, day and night are caused by the Earth's rotation on its axis.
Hope this helps!
Earth experiences day and night due to its rotation on its axis. When a part of Earth is facing the Sun, it experiences daylight while the part not facing the Sun experiences night. This is different from the Earth's revolution around the Sun, which causes the change of seasons.
The best description of why Earth has day and night is that the Earth rotates on its axis. Imagine the Earth as a spinning top. One full rotation or one complete spin of Earth on its axis is what we understand as a 24-hour day. When a part of the Earth is facing the Sun, it experiences daylight, and when it is not facing the Sun, it experiences night. It's this rotation that gives us the cycle of day and night. This rotation is fundamentally different from the Earth's revolve around the Sun, which takes about 365.24 days and gives us our year.
