The model of the atom which was supported by the gold foil experiment was nuclear model.
Scientists wanted to prove plum pudding model, however, their experiments led to interesting results which made them hypothesize the nuclear model of the atom instead.
selective breeding has changed organisms over time by paring that organism up with another organism of its kind with desirable traits. take dogs for example, through selective breeding we now have many different types of dogs with different abilities. i hope this helps
Answer:
D: There is no wind on the moon
Answer: movement is always voluntary
Explanation:
Muscles are contractile:
- Contractility is the ability of muscle cells to forcefully shorten. Think of having the ability to flex a muscle.
Muscles are excitable:
- Excitable tissue can conduct or transmit electrical impulses. Basically, it can react to stimulus, which may be delivered from a motor neuron or a hormone. For example, the hormone epinephrine helps muscles to produce force.
Muscles respond to stimulus:
- well since muscles are an excitable tissue, they can react to stimulus. (see answer above)
————————
Muscle movement is NOT always voluntary:
- Some muscle movement is voluntary, which means it is under conscious control. For example, a person decides to open a book and read. Other movements are involuntary, meaning they are not under conscious control, such as the contraction of your pupil in bright light, breathing, blinking, your heart beating, etc.
- Therefore, the correct answer is:
movement is always voluntary
