When applying the process of science which of theseis tested 1.a question, 2.an observation, 3.a conclusion, 4.a prediction
Answers
4. a prediction
Explanation:
According to the scientific method, an experiment is conducted to test a prediction/hypothesis stemming from the previous question.
A conclusion ... usually called a "theory" ... is tested. (3)
One great way to test a conclusion is to follow up on its predictions, and see how they turn out.

Answer:
I amperes
Explanation:
Newton is the unit of force. Hence 4 newton is not the current “I”
Joules is the unit of energy and hence it do not signify current I
Watt is the unit of power i.e the rate of transfer of energy.
Ohm is the unit of resistance produces thereby obstructing the flow of current
And Volts is the unit of voltage or potential difference between two ends of an electric circuit. Thus, it is also does not signifies current.
Thus, I amperes

C. Only chemical changes occur when you cook a frozen pizza and only physical changes occur when you make pizza from scratch.
D. You cause chemical changes in vegetables by cutting them into small pieces
Answers
Final answer:
Both physical and chemical changes occur when you make pizza from scratch.
Explanation:
The correct statement from the given options is: Both physical and chemical changes occur when you make pizza from scratch. When you make pizza from scratch, physical changes occur when you mix and shape the ingredients, while chemical changes occur during the process of baking the pizza dough and melting the cheese. These changes involve the breaking and forming of chemical bonds, resulting in the creation of new substances with different properties.
Additionally, cheese undergoes a chemical change as it melts, proteins denature, and Maillard reactions occur, resulting in the development of new flavors and textures.
Thus, making pizza from scratch is a dynamic process that encompasses both physical and chemical changes, highlighting the fascinating chemistry and physics behind this delicious culinary endeavor.

The formation of rust or the iron oxide, is by the chemical reaction between iron and atmospheric oxygen. Hence, it is a chemical change involving the formation of new product.
What is a chemical change?
A chemical change is accompanied by the making or breaking or chemical bonds and the formation of new products. Whereas, a physical change does not involve the change in chemical bond. Phase transitions, change in size,shape etc. are physical changes.
The rust formed in the iron material is iron oxide or Fe₂O₃. This process of forming rust by the action of air or water is called corrosion. Iron reacts with atmospheric oxygen or oxygen from water forms the rust.
The formation of rust makes the material destroy and to prevent this process some anticorrosive materials have to be applied. Hence, formation of rust is a chemical change.
