Once infected cells have sensed an invading pathogen, they secrete molecules called cytokines and chemokines. Cytokines such as interferons are molecules that signal neighbouring cells and induce an antiviral state in them. These cells are then primed to resist an infection with the invading virus.
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:
The answer is A True
Explanation:
Bone remodeling is a process that take places annually throughout the bone tissue to be able to renew, they are enzymes that adhere and destroy the old bone to give rise to osteoblasts forming new tissue, since the bone is a tissue in constant process of physiological resorption and remodeling. This process is positive until the third decade of life, then it could become pathological.
