Transformation of Energy Video
1. Explain an example of how energy is transferred from one form to another in the video.

2. Draw an energy flow diagram showing the energy transformation from one form to another.

Answers

Answer 1
Number one would be (if I’m understanding correctly) just that a wind turbine would use kinetic energy from the wind to power a generator that turns the wind kinetic energy into electrical energy for an example.

Two would be, drawing a wind turbine with little lines at the top that represent kinetic energy (label them) from the wind and then little lines at the bottom that represents electrical energy going into a generator that’s being powered.

Organisms can either be made of one cell or made of more than one cell

Answers

Answer:

The statement is true.

Explanation:

Organisms can be unicellular (made up of one cell) or multicellular (consisting of more than one cell).

I hope this helps in any way :)

Unicellular organisms are made up of only one cell that carries out all of the functions needed by the organism, while multicellular organisms use many different cells to function. Unicellular organisms include bacteria, protists, and yeast.

If there is not one scientific method, then what do all scientists have in common???
Plsss I will give brainliest, and 12 points !!

Answers

Answer:

One thing that all scientists have in common is that they find problems in the world, and attempt to seek answers to those problems. Everything that scientists do begins with observations, leading to questions.

Let me know if this helps!

While no single scientific method is uniformly followed by all scientists, there are certain common aspects and concepts that scientists share in their search of knowledge and understanding.

These are some examples:

Scientists rely on empirical evidence gathered via observation, experimentation, and measurement.

Systematic and Objective Investigation: Scientists explore and analyse events using systematic and objective approaches.

Scientific discoveries should be repeatable, which means that other researchers should be able to replicate the tests and achieve identical results.

Thus, although scientists' methodologies and approaches differ between fields, these basic principles drive their research and contribute to the collective growth of scientific knowledge.

Why do scientists use models, and why do all models have limitations???
Plsss help! :) I will give brainliest!! :)

Answers

Answer:

Scientists use  models to represent data/evidence. However, all models have limitations. However, models are simplified versions of reality, and can't be totally accurate in representation.

Hope this helps :)

Answer:

Since models are simpler than real objects or systems, they have limitations. ... It may not predict the behavior of the real system very accurately. But the more computing power that goes into the model and the care with which the scientists construct the model can increase the chances that a model will be accurate.
