USE YOUR OWN WORDS. Each question must have a three sentence long answer!
1. If there is not one scientific method, then what do all scientists have in common?
2. How is a theory similar to and different from a law?
3. What is the difference between data and evidence?
4. Why do scientists use models, and why do all models have limitations?
5. What makes a good scientific question?ANSWER Why do scientific ideas sometimes change?
Answer:
1. Scientists use experimentation and careful observation to collect evidence to support those explanations. Although there is no single scientific method, all types of scientists use the eight science and engineering practices in different orders and combinations to do their work.
2. In simplest terms, a law predicts what happens while a theory proposes why. A theory will never grow up into a law, though the development of one often triggers progress on the other
3.Data is just data and has no intrinsic meaning on its own. Evidence has to be evidence for or of something; an argument, an opinion, a viewpoint or a hypothesis. The evidence you use depends on your argument.
4.All models have limitations because they are not representative of every possible scenario. They use current knowledge and scientific data, but as those are subject to change, the models based off that knowledge and data are subject to change as well. ... Scientific models are not a replacement for experimentation.
5.What makes a good scientific question is that it can be answered by direct observations or with scientific tools. Examples of questions that are not scientific are based on values or opinions like what people believe is right or wrong, or beautiful or ugly. (to the part that says ANSWER ---->) Scientific ideas change over time as our evidence improves. The more experiments we do and the more data we collect, the better our scientific ideas become. ... When a brand-new idea is suggested, the first step is to collect evidence. But even when that evidence is collected, understanding it can be difficult.

I NEED IT ASAP plssss thank you ( until 12am today November 5, 2021 ) last picture is the storyyy
Answer:
1. The stronger the intermolecular forces are, the more energy is required, so the higher the melting point is. Many intermolecular forces depend on how strongly atoms in the molecule attract electrons — or their electronegativity. ... Hydrogen bonds are among the strongest intermolecular forces.

Scientists have identified a link in the ice cores between ___________-________ and atmospheric temperatures over thousands of years.
Answer:
Explanation:Ice sheets have one particularly special property. They allow us to go back in time and to sample accumulation, air temperature and air chemistry from another time[1]. Ice core records allow us to generate continuous reconstructions of past climate, going back at least 800,000 years[2]. By looking at past concentrations of greenhouse gasses in layers in ice cores, scientists can calculate how modern amounts of carbon dioxide and methane compare to those of the past, and, essentially, compare past concentrations of greenhouse gasses to temperature.
Ice coring has been around since the 1950s. Ice cores have been drilled in ice sheets worldwide, but notably in Greenland[3] and Antarctica[4, 5]. High rates of snow accumulation provide excellent time resolution, and bubbles in the ice core preserve actual samples of the world’s ancient atmosphere[6]. Through analysis of ice cores, scientists learn about glacial-interglacial cycles, changing atmospheric carbon dioxide levels, and climate stability over the last 10,000 years. Many ice cores have been drilled in Antarctica.

Explanation:
The impacts to humans, nature and the planet caused by fossil fuels. (needs to be a paragraph)
Answer:
fossil fuels are not good for us. there not good for the earth! it makes large amounts of carbon dioxide when ever it is burned. it is cuasing global warming! we burn it for energy, we need a difrent energy sorce, that is cleaner and better!
i hope this is good enough !<3

Write TWO examples of Newton's third law in "The Martian."
For every action force, there is an equal and opposite reaction force.
Answer:
Newton's Third Law is showed when they use the air lock to slow down the velocity. The action is the air shooting out from the ship and the reaction is the velocity slowing down. Another action would be the bomb making the whole in the airlock door which will have a reaction of the ship slowing down
Explanation:
Newton's Third Law is showed when they use the air lock to slow down the velocity. The action is the air shooting out from the ship and the reaction is the velocity slowing down.
What is Newton's Third law?Newton's Third Law is defined as when two bodies come into contact, they exert forces on one another that are both equal in strength and directed in opposing directions.
Ball bouncing: When a ball strikes the ground, it exerts action force on the surface. The ball bounces back as a result of the ground's reaction force. A bird's wings act as an action force, pushing air downward, and act as a reaction force, pushing the bird upward.
Thus, Newton's Third Law is showed when they use the air lock to slow down the velocity. The action is the air shooting out from the ship and the reaction is the velocity slowing down.
