The bone cell responsible for breaking down bone tissue is the osteoclast, whereas the bone cell that produces new bone tissue is the osteoblast.
<h3>
What is osteoclast and osteoblast?</h3>
- In those processes, osteoblast and osteoclast are the two major cells involved.
- Aged bone resorption is caused by osteoclasts, whereas new bone creation is caused by osteoblasts.
- Under healthy settings, the processes of resorption and creation are steady.
- The cells known as osteoclasts mediate bone loss in pathologic situations by increasing their resorptive activity and degrading bone to start normal bone rebuilding.
- They originate from myeloid/monocyte lineage progenitors that circulate in the circulation after developing in the bone marrow.
- On the surface of bones, there are osteoblasts, bone lining cells, and osteoclasts, which develop from progenitor cells, which are regional mesenchymal cells.
- Osteocytes are created by the fusing of mononuclear blood-borne progenitor cells, and they penetrate the interior of the bone.

Answer: It shows the distribution of the population with respect to a characteristic, quantitative and continuous, such as the weight or height of a population. It is used to determine the degree of homogeneity of the values studied, or to see the degree of variability, and therefore, the dispersion of all the values taken by the parts.
Explanation:
A histogram is a graphical representation of a variable using bars. In such a bar, <u>its area is proportional to the frequency of the values represented</u>. Thus, it shows the distribution of the population, or of the sample, with respect to a characteristic, quantitative and continuous, such as the weight or height of a population. It is used to determine the degree of homogeneity of the values studied, or to see the degree of variability, and therefore, the dispersion of all the values taken by the parts.
In order to construct a histogram first we need to have a frequency table with all the information. On the abscissa axis (horizontal axis) the intervals are placed from smallest to largest. On the ordinate axis (vertical axis), the absolute frequencies of each of the intervals are represented. Then, the rectangular bars of equal width are drawn, and the height represents the absolute frequency. All bars touch the bars next to each other, unless an interval has zero frequency (the height of the bar will also be zero).
<u>Thus, histograms are used to describe populations since they represent a variable and in what proportion of the population it is found.</u>
The answer is D. 3.33 A
In parallel connected devices, circuits are also placed parallel. It is known that in parallel circuits, total voltage is equal to the voltage of each device.
So, we know that:
Device 1 - R1 = 12 ohms
Device 2 - R2 = 4 ohms
Total voltage - V = 40V = V1 = V2
If V = I × R, for the first device is V1 = I1/R1.
⇒ I1 = V1 ÷ R1
⇒ I1 = 40 V ÷ 12 ohms
⇒ I1 = 3,33 A
