Answer:
True:
A heat source could be considered a source of pollution.
Explanation:
The reason behind this is that global warming is attributed to the general warming o the planet's temperature without making a specification of a single source or a singular type of origin. It just accounts for warming. One of the major discoveries of this problem was the fast-food chain's contribution to global warming. Saying that the fast-food industry provides a considerable amount of warming to the planet.
A prediction is a guess what might happen based on observation.
Here are some steps to think about to make a dependable prediction:
Collect data using your senses, remember you use your senses to make observations.
Search for patterns of behavior and or characteristics.
Develop statements about you think future observations will be.
Test the prediction and observe what happens.
A hypothesis is a possible explanation for a observation or problem that can further be tested by experimentation. Hypothesis' are also known as educated guesses.
Here are the steps to form a hypothesis:
When developing a hypothesis think about any observations or previous knowledge you know about the variables.
Express what you think will be the effect of changing one of the variables (Independent variable) on the other variable you expect to change (Dependent variable).
Develop your hypothesis using a statement.
A example of a hypothesis statement would be, As the (independent variable) ( describe how you would change it) , then the (dependent variable ) will (describe the effect)
Answer:Different cells have different jobs to do. Each cell has a size and shape that is suited to its job. Cells that do the same job combine together to form body tissue, such as muscle, skin, or bone tissue. Groups of different types of cells make up the organs in your body, such as your heart, liver, or lungs
Explanation:
Answer:
When conducting research, scientists use the scientific method to collect measurable, empirical evidence in an experiment related to a hypothesis (often in the form of an if/then statement), the results aiming to support or contradict a theory.
