Okay, so I have this question here about which step ensures the validity of investigation results. The choices are A through D. Let me think through each option carefully.
First, the question is asking which step is most likely to make sure the results are valid. Validity in research usually means that the results are accurate, reliable, and can be repeated. So, I need to pick the option that best supports these aspects.
Looking at the choices:
A: Using a computer to graph results. Hmm, graphing results is more

I think the summer solstice is around June. That's when the North Pole is tilted towards the Sun the most, making June days the longest. So in New York, June should have the longest daylight.

Okay, so I'm trying to figure out why the toy car slowed down on the carpet but moved fast on the wood. Hmm, I remember that when objects move, they can experience different forces. The car was pushed, so it had some initial speed on the wood floor. But when it got to the carpet, it started slowing down.
I think friction might be a factor here. Friction is the force that opposes motion between two surfaces. So, if the carpet is softer or has

</think><think>
Okay, so I'm trying to figure out this question about sulfur scrubbers and the environmental problem they're addressing. Let me break it down step by step.
First, I know that sulfur scrubbers are devices used in coal-fired power plants. Their main purpose is to reduce emissions, specifically sulfur dioxide. So, the question is asking which environmental problem these scrubbers are targeting.
I remember that sulfur dioxide is a pollutant. When it's released

Okay, so I have this question here asking which system of the human body provides protection to most of the major organs. The choices are A: skeletal system, B: circulatory system, C: respiratory system, D: muscular system. I need to figure out which one is correct.
First, I should probably recall what each system does. The skeletal system is made up of bones and joints. I know that bones provide structure and support. For example, the skull protects the brain, and the rib

Okay, so I need to figure out which item changes electrical energy into heat. The options are Alarm clock, Hand dryer, Fan, and Telephone.
First, I know that electrical energy can be converted into different forms like light, heat, or motion. So, I'm looking for something that specifically turns electricity into heat.
An alarm clock uses electricity to run, but its main purpose is to keep time and alarm, not to produce heat. So probably not A.
A hand dryer uses electricity to heat up elements
