Answer and Explanation:
The functions of the red and yellow bone are as under:
- Red bone marrow are a large portion of the red and white platelets and platelets themselves are created in the red bone marrow.
- Hemopoetic division of stem cells happens. the red color of the Hemoglobin imparts its color to the bone marrow as a result of which it appears red.
- Yellow bone marrow produces ligament and bone. The yellow color of this bone marrow is due to the presence of a fat containing acrotoid pigment in it.
B lymphocytes
Antibodies are produced by specialized white blood cells called B cells (B lymphocytes)
Complementary DNA (cDNA) is a DNA copy of a messenger RNA (mRNA) molecule produced by reverse transcriptase, a DNA polymerase that can use either DNA or RNA as a template.
<h2>Development of Plant Needles</h2>
Explanation:
- Seed of pitch pine treated with colchicine delivered tetraploid seedlings which had thick and sporadic needles and less fortunate tallness and diameter growth than ordinary seedlings.
-
In test of colchicine-initiated polyploidy in pines, researcher found that a significant number of the polyploid plants returned to a diploid development in light of the fact that the polyploid cells partitioned at a more slow rate and were overwhelmed by the more quickly developing diploid cells which encompassed them.
-
The primary needles of both diploid and polyploid plants were more effective at low light intensity than secondary needles, and they had lower compensation points.
Answer:
Normal force, gravity and Friction.
Explanation:
The forces acting on the book are normal formal force which act or exerts by the table on the book while on the other hand, gravity is a force that acts in the downward direction. Friction is the force that acts against the motion of the book and is responsible for lowering speed of the book that is sliding on the surface of the table. If the friction is low between the book and table then the book moves easily on the surface.
