Q: What is the term for the number of waves that pass a fixed point in a given amount of time? Read this paragraph and choose the correct option from the provided answers: Wave frequency is the number of waves that pass a fixed point in a given amount of time. Higher frequency waves have more energy. Wave speed is calculated as wavelength multiplied by wave frequency. Wave speed is affected by the medium through which a wave travels. Choices: - wave speed - wave distance - wave velocity - wave frequency A:
wave frequency

Q: The average length of a woman's menstrual cycle is what? Read this paragraph and choose the correct option from the provided answers: The Menstrual Cycle Now that we have discussed the maturation of the cohort of tertiary follicles in the ovary, the build-up and then shedding of the endometrial lining in the uterus, and the function of the uterine tubes and vagina, we can put everything together to talk about the three phases of the menstrual cyclethe series of changes in which the uterine lining is shed, rebuilds, and prepares for implantation. The timing of the menstrual cycle starts with the first day of menses, referred to as day one of a woman's period. Cycle length is determined by counting the days between the onset of bleeding in two subsequent cycles. Because the average length of a woman's menstrual cycle is 28 days, this is the time period used to identify the timing of events in the cycle. However, the length of the menstrual cycle varies among women, and even in the same woman from one cycle to the next, typically from 21 to 32 days. Just as the hormones produced by the granulosa and theca cells of the ovary "drive" the follicular and luteal phases of the ovarian cycle, they also control the three distinct phases of the menstrual cycle. These are the menses phase, the proliferative phase, and the secretory phase. Choices: - 19 days - 16 days - 5 days - 28 days A:
(Answer)
28 days

Ques:Q: The ability for a plasma membrane to only allow certain molecules in or out of the cell is referred to as what? Read this paragraph and choose the correct option from the provided answers: The plasma membrane forms a barrier between the cytoplasm inside the cell and the environment outside the cell. It protects and supports the cell and also controls everything that enters and leaves the cell. It allows only certain substances to pass through, while keeping others in or out. The ability to allow only certain molecules in or out of the cell is referred to as selective permeability or semipermeability. To understand how the plasma membrane controls what crosses into or out of the cell, you need to know its composition. Choices: - periodic permeability - total permeability - moderate permeability - selective permeability A:

Ans:selective permeability

Q: In neurons, what often involves gated sodium channels? Read this paragraph and choose the correct option from the provided answers: Choices: - fermentation - excitation - polarization - depolarization A:
depolarization
