Question:

Which of the following statements accurately describe the role of the sun and gravity in the water cycle on Earth?

Answer Choices:

A) The sun provides energy that causes water to evaporate from Earth's surface.
B) Gravity pulls precipitation down to Earth's surface, completing the cycle.
C) The sun's energy is responsible for causing gravity to act on water droplets.
D) Without the sun, water would not be able to condense into clouds.
E) Gravity helps in the formation of clouds by holding water vapor in place.

✅ Answer:

The sun provides energy that causes water to evaporate from Earth's surface.; Gravity pulls precipitation down to Earth's surface, completing the cycle.

💡 Explanation:

The sun's energy heats water in oceans, rivers, and lakes, causing it to evaporate into water vapor.
Gravity is responsible for pulling water back to Earth's surface as precipitation, ensuring the continuous cycling of water.
The sun does not directly influence gravity, and gravity does not hold water vapor in place; rather, it pulls precipitation down.

Short answer📘 MS-LS2-4🧠 DOK 1

Question:

Explain how the introduction of a new predator into an ecosystem can affect the populations of existing species. Provide one example to support your explanation.

✅ Answer:

The introduction of a new predator can decrease the populations of existing prey species as they are consumed by the predator. This can lead to a decline in those prey species and potentially disrupt the balance of the ecosystem. For example, if a new type of predatory fish is introduced into a lake, it might reduce the population of smaller fish species that it preys on.

💡 Explanation:

Introducing a new predator can upset the existing predator-prey relationships within an ecosystem.
The added predation pressure can lead to a decline in prey populations, which can have cascading effects on other species and the overall ecosystem balance.

Question:

A pet store has a total of 24 fish tanks. Each tank holds the same number of fish. If there are a total of 168 fish in the store, how many fish are in each tank?

Answer Choices:

A) 6 fish
B) 7 fish
C) 8 fish
D) 9 fish

✅ Answer:

7 fish

💡 Explanation:

To find the number of fish in each tank, we need to divide the total number of fish by the number of tanks.
So, solve the equation 24x = 168.
Divide both sides by 24 to find x: x = 168 / 24 = 7.
Therefore, there are 7 fish in each tank.
