You see a worm crawling along the ground and wonder if scientists consider it living or nonliving. Which item below would not be true when classifying the worm as living or non‐living?
A worm can move so it must be living.
A worm can reproduce and make little baby worms (called wormlets) so it must be alive.
Worm’s pass dirt through their body pulling food out and discarding the stuff they don’t want so it must be alive.
If you cut a worm in half, it can re‐grow so it must be alive.
Answer: a. A worm can move so it must be living.
Explanation:
If a worm is moving it is classified as a moving worm also known to be living if moving.
A worm could reproduce therefore it is living.
Worms do pass dirt into and through there bodies to eat of the minerals and discarding things through and let out.
If you do cut a worm in half it may damage it but since it has basically two heads on girl one boy and cut in half it may split them up, and make damage but they will eventually grow back if the injuries are not severe.

Explain why action and reaction forces are not balanced forces.
Answer:
Explanation:
Newton's third law of motion states that every action has an equal and opposite reaction. This means that forces always act in pairs. Action and reaction forces are equal and opposite, but they are not balanced forces because they act on different objects so they don't cancel out. hope that helped
Answer:
Action and reaction forces are equal and opposite, but they are not balanced forces because they act on different objects so they don’t cancel out.

Which statement describes the energy changes that occur when water in a tea kettle is heated on a stove that uses natural gas
A:Some of the chemical energy in the natural gas transforms into thermal energy, which heats the water. Then some of the thermal energy changes into sound energy when the water forms steam and the steam leaves the kettle.
B:Some of the electrical energy in the natural gas transforms into thermal energy, which causes the water to form steam. Then some of the thermal energy changes into sound energy and light energy when the steam leaves the kettle.

A student used a portable electric drill to remove screws from a broken wooden table. He noticed that the screws holding the table together were warm to the touch after being removed from the wood. Which statement best explains this phenomenon?
A:Electrical energy from the drill was converted into chemical energy due to conductivity.
B:The process of removing the screw concentrated the thermal energy that was already present in the wood
Answer:
A.
Electricity can travel through metal, such as the screws, creating a conductor.

A book is sliding across a horizontal tabletop. As it slides, slows down. Which of the following statements best explains this situation?
There is a balanced force on the book caused by gravity.
There is no upward force acting on the book.
There is an unbalanced force on the book caused by friction.
There are no unbalanced forces acting on the book.
A book is sliding across a horizontal tabletop. As it slides, slows down. There is an unbalanced force on the book caused by friction.
What is friction ?The force preventing sliding against one another of solid surfaces, fluid layers, and material components is known as friction. There are several kinds of friction, The force that opposes the relative lateral motion of two solid surfaces in contact is known as dry friction.
When a stick is used to beat the carpet, a little amount of static friction occurs, holding the dust to the carpet. When we beat a carpet with a stick, the stick's external force forces the carpet to move away from the dust by overcoming friction.
A frictional force or an opposing force is produced when two rough surfaces come into contact with one another. This force can occasionally be transformed into heat.
Thus, option C is correct.
