Ques: Q: What begins when a neuron receives a chemical stimulus? Read this paragraph and choose the correct option from the provided answers: A nerve impulse begins when a neuron receives a chemical stimulus. The impulse travels down the axon membrane as an electrical action potential to the axon terminal. The axon terminal releases neurotransmitters that carry the nerve impulse to the next cell. Choices: - a induce impulse - a metabolism impulse - nerve reaction - a nerve impulse A:
Ans: a nerve impulse

Ans: asexual

Ques: Q: What is it called when feces move along the colon too slowly? Read this paragraph and choose the correct option from the provided answers: Choices: - respiratory - diarrhea - relaxation - constipation A:
Ans: constipation

Ques: Q: What term describes motion that repeats itself at regular time intervals, such as exhibited by a vibrating guitar string? Read this paragraph and choose the correct option from the provided answers: When you pluck a guitar string, the resulting sound has a steady tone and lasts a long time. Each successive vibration of the string takes the same time as the previous one. We define periodic motion to be a motion that repeats itself at regular time intervals, such as exhibited by the guitar string or by an object on a spring moving up and down. The time to complete one oscillation remains constant and is called the period T . Its units are usually seconds, but may be any convenient unit of time. The word period refers to the time for some event whether repetitive or not; but we shall be primarily interested in periodic motion, which is by definition repetitive. A concept closely related to period is the frequency of an event. For example, if you get a paycheck twice a month, the frequency of payment is two per month and the period between checks is half a month. Frequency f is defined to be the number of events per unit time. For periodic motion, frequency is the number of oscillations per unit time. The relationship between frequency and period is. Choices: - gravitational pull - specific speed - apparent motion - periodic motion A:
Ans:
periodic motion
