Answer:
C) 30 minutes
Explanation:
The PAG (physical activity guidelines) recommends at least 30 minutes of physical activity in a daily basis.
Since sample a has data more tightly clustered about the mean compared to sample b, we can say that the variance for sample a is lower than that for sample b.
What is variance:
Variability gets used to measure the central tendency's closeness to the values. A measure of central tendency that can get used is mean. Mean refers to the average for some given values and gets determined by dividing the sum of those values by the number of values. The variance refers to the average squared difference of each value from the mean.
When the variance is lower, the data is less spread out. Thus, data being more tightly clustered about the mean reflects lower variance. Since sample a has data more tightly clustered about the mean compared to sample b, it can be concluded that the variance for sample a is lower than that for sample b.

Answer: Hilar cells resemble like Leydig cells of Testis , produce steroids, contain Reinke crystalloids, lipids, lipochrome pigments. They also resemble steroid cells by EM with microtubular smooth endoplasmic reticulum, mitochondria with a tubular cristae. Hilar cells are seen in the fetal ovary but not in infancy and childhood.They reappear at puberty.
Explanation:
Hilus cells are androgen producing cells found in the ovarian hilum. It is analogous to the male Leydig Cells. They are found in the ovarian hilum and mesovarium often adjacent to nerves.•Closely associated with large hilar veins and lymphatics and may protrude within their lumina; also associated with nerves. They also produce masculine like tumours.
The most common special considerations when using an AED involve pediatric patients, patients who are wet or moist, patients with excessive hair, patients with a medication patch, or patients who have a device that could get in the way when you're trying to deliver a shock.
