How does this image demonstrate that matter is made up of particles too small to see? deflated soccer ball and pump next to an inflated soccer ball and a pump

The air particles pumped into the ball change the size and shape of the ball.
The air moves from the ball and causes the pump to change its size and shape.
The air pump gives the ball energy that increases its size and changes its shape.
The particles of the pump move into the soccer ball and increase its size.

Which of the following would be a body response when stepping outside without a coat on a snowy day? a. senaceous glands. secrete more senum b. more liquid is transported by the body to the skin fir insulation c. blood vessels in the skin narrow and contract d. blood vessels in the skin expand

Which label identifies the part of the atp molecule that changes when energy is released in the cells of all living things

Choose the incorrect statement (a) the motor end plate membrane is only capable of generating graded potentials, but it is contiguous with the skeletal muscle sarcolemma, which can generate action potentials. (b) propagation of an action potential through the t-tubules into the sarcoplasmic reticulum triggers the release of ca++ into the cytoplasm of a skeletal muscle fiber. (c) the generation of suprathreshold endplate potentials in multiple muscle fibers could be due to the increased frequency of action potential generation at the axon hillock of a single motor neuron. (d) a greater amount of ach would be found in the presynaptic vesicles of a motor unit that fired several action potentials after exposure to botulinum toxin, than in a motor unit that fired several action potentials after exposure to the venom of the krait snake (which contains α-bungarotoxin).
