Answer:
a. Osteogenic cells can differentiate into osteoclasts
Explanation:
Osteoblasts are the cells that are formed from osteogenic cells. The osteogenic cells enter the process of bone formation. There is a secretion of organic compounds and salts to form osteoblast. Osteoclasts are the very large cells that are formed when many monocytes fuse together and are concentrated in endosteum. Osteoclasts are the cells responsible for bone resorption.
Answer:
"The latitude of a region determines how much sunlight the area receives" this statement says about why the latitude of a region influences its climate.
Explanation:
The latitude determines the sunlight of the area receives because, the more the latitude the sharper will be angle of the sun's rays which will reach the surface. Means that the rays of the sun are being spread over the broader area. Hence, More the latitude receive will be the less than the lower latitude areas located nearer to the equator. As, we know the sun's ray first strikes over the Earth's surface which is near the equator as these places receive direct solar radiation. At greater latitude the solar radiations gets spread in more area and hence the temperature also reduces.

<h2>Question:- </h2>
If you are to conduct a DNA analysis using a blood sample which of the blood components will you use
<h2>Options :- </h2>
1.) Red Blood Cells
2.) White Blood Cells
3.) Plasma
4.) Platelets
<h2>Answer:- </h2>
Option 2.) White Blood Cells
<h2>Explanation:- </h2>
- Red Blood Cell(RBC) , Plasma , Platelets lack DNA
- White Blood Cell (WBC ) only have DNA
- RBC lack nucleus to make space for O2 as the work is to carry O2 with help of hemoglobin
- Platelets are the cell fragments of the large cells they help in clotting so too lack nucleus
- Plasma is the fluid part of the blood. so it contain water in its most part and too lack DNA bez plasma don't contain any cells
- WBC are the only cells which have well defined nucleus with DNA in above mentioned options
