Explanation:
A student conducts an experimenting to test how the temperature of a ball affects its bounce height. The same ball is used for each test, and the ball is dropped from the same height each time what is the independent variable
the independent variable is what you're testing or changing in an experiment, so the answer is the temperature of the ball when its dropped.

At the top of its swing, a pendulum has zero kinetic energy. How much potential energy does it have at the bottom of its swing?
A.
maximum
B.
1/2 as much
C.
1/4 as much
D.
zero
At the bottom of its swing, it has the lowest potential energy. Option D is correct.
What is potential energy?Potential energy is the energy stored in an object due to its position relative to other objects.
Here,
At the top of its swing, a pendulum has zero potential energy. At the bottom of its swing, it has the lowest potential energy.
In the case of a pendulum, potential energy is stored in the pendulum due to its position relative to the Earth. The higher the pendulum is, the more potential energy it has, and the lower it is, the less potential energy it has.
At the bottom of its swing, the pendulum is at its lowest point, so it has the lowest amount of potential energy. Thus, the answer is D) Zero.

Countries around the world are trying to slow down or reverse the effects of climate change. Based on what you know about the greenhouse effect, which of the following actions would be likely to slow the rise in Earth's average temperature?
Answer:
Greenhouse gases would warm the earth up causing global warming
Explanation:
To solve this we must be knowing each and every concept related to greenhouse effect. Therefore, greenhouse effect would be likely to slow the rise in Earth's average temperature.
What is greenhouse effect?The Earth's surface is heated by the greenhouse effect all the way up to the troposphere. Higher concentrations of methane, carbon dioxide, and other gases cause it to occur.
The energy from the sun's heat is reflected back into space as infrared radiation when the Earth's surface cools. The concentrated gases inside the greenhouse effect absorb energy, raising the earth's temperature as a result. Thus, there is a link between the global warming and the greenhouse effect. Greenhouse effect would be likely to slow the rise in Earth's average temperature.
Therefore, greenhouse effect would be likely to slow the rise in Earth's average temperature.

Water bears are microscopic animals. When water bears are exposed to a vacuum of space, about 30% of them can survive.
A scientist is doing an experiment on water bears and vacuum exposure.
Which option is a prediction that relates the outcome of the scientist’s experiments with probability?
1. The scientist thinks water bears can survive vacuum exposure because they have little water in their bodies.
2. The scientist thinks that under some conditions, up to 40% of the water bears can survive.
3. The scientist thinks that there is a 15% chance that he will receive funding for more research.
4. The scientist thinks that other animals can also survive vacuum exposure.
Answer:
I would number 1
Explanation:
Tiny invertebrates called ‘water bears’ can survive in the vacuum of space, a European Space Agency experiment has shown. They are the first animals known to be able to survive the harsh combination of low pressure and intense radiation found in space.
Water bears, also known as tardigrades, are known for their virtual indestructibility on Earth. The creatures can survive intense pressures, huge doses of radiation, and years of being dried out.
This is some old research found about them hope u can find something from these two paragraphs.
The scientist thinks water bears can survive vacuum exposure because they have little water in their bodies. Hence, option (1) is a prediction that relates the outcome of the scientist’s experiments with probability.
What is water bear or Tardigrade?Tardigrades are a phylum of eight-legged segmented micro-animals, also known as water bears or moss piglets. Johann August Ephraim Goeze, a German biologist, initially identified them as Kleiner Wasserbär in 1773. ("little water bear"). They were given the Tardigrada moniker in 1777 by the Italian naturalist Lazzaro Spallanzani, which translates to "slow steppers."
They have been discovered in many different biospheres on Earth, including the Antarctic, deep water, tropical rainforests, and mountaintops. Individual species of tardigrades may endure extreme conditions that would swiftly kill most other known forms of life, including exposure to extreme temperatures, extreme pressures (both high and low), air deprivation, radiation, dehydration, and malnutrition. Even in space, tardigrades have managed to survive.
