1. What would happen if a person fell into a black hole?
2. Why it takes more genes to make a tomato than a human.
3. How the placebo effect works.
Answer:
B. Neurons are cells that conduct electrical impulses.
Explanation:
Red blood cells carry oxygen throughout the body. White blood cells protect against pathogens and aid in blood clotting after injury. Blood cells cannot contract.
Neurons generate and conduct electrical impulses. So this one is correct.
Epithelial cells line the cavities and surfaces of blood vessels and organs, protect underlying tissue, regulate the exchange of chemicals, and secrete various substances. They do not react to stimuli, however neurons do.
Smooth muscles helps the skeleton move, smooth muscle is found in blood vessels and some organs, and cardiac muscle helps the heart beat and pump blood. They are however, not components of blood.
The statement that correctly describes the relation in the question is ; ( A ) As wavelength decreases, frequency increases, energy increases and the speed remains the same.
The Frequency of a wave travelling in a medium is directly proportional to the energy produced by the wave and inversely proportional to the wavelength of the wave.
Changes in the wavelength and frequency of a wave has no effect on the wave speed. but has an effect on the energy produced by the wave. therefore the wave speed remains constant regardless of the changes in wavelength and frequency
Hence we can conclude that As wavelength decreases, frequency increases, energy increases and the speed remains the same.
