Answer

Question 1: Which would best increase the magnetism of a temporary magnet?

Explanation:

Step1: Recall magnetism factors

Magnetism of an electromagnet (temporary magnet) is related to current and number of turns.

Step2: Analyze each option

  • Option A: Larger battery means more voltage, more current, more magnetism.
  • Option B: Reducing turns decreases magnetism.
  • Option C: Insulator won't conduct current, no magnetism.
  • Option D: Increasing temperature generally weakens magnetism.

Answer:

A. Use a larger battery.

Question 2: Which best allows a cockroach to move fast when someone tries to step on it?

Explanation:

When in danger, cockroaches rely on a reflex action. Hairs linked to the nervous - system detect the threat and trigger a rapid escape response.

Answer:

D. Reflex, Hairs Linked to Nervous System

Question 3: An area of woods up North has brown and white foxes. For over 300 years, the grounds have been covered in snow. For this new ecosystem, which color would be highest in this population? Why?

Explanation:

In a snowy environment, white - colored foxes have better camouflage, which helps them avoid predators and catch prey more effectively. So, they are more likely to survive and reproduce.

Answer:

Not provided in options (should be white, camouflage)

Question 4: Which of the following is a negative result of humans building homes in an unpopulated area?

Explanation:

Building homes in an unpopulated area usually doesn't cause an increase in earthquakes. But it can disrupt the local ecosystem.

Answer:

No correct option provided in the given choices (deforestation, habitat loss are common negative results)
