Answer:
B. phagocytes
Explanation:
Phagocytosis is a process wherein a cell binds to the item it wants to engulf on the cell surface and draws the item inward while engulfing around it. The process of phagocytosis often happens when the cell is trying to destroy something, like a virus or an infected cell, and is often used by immune system cells.
A - In the liquid state water has a higher density more than in solid. Reason being ice floats in water, and first is formed on its surface and then in the bottom. Therefore, ice covers the water column as a blanket.
B - Water is a universal solvent for polar compounds.Then the property is being polarity.
C - high surface tension, cohesion, and adhesion.
D - There is higher heat of vaporization
E - It is cohesion
F - hydrophobic interaction, cohesion and adhesion.
G - Adhesion and capillary action.
Cohesion is termed as the attraction which is between molecules of the same substance.
Adhesion are termed as fibrous bands which are formed between organs and tissues. It often occurs as a result of injury during time of surgery.
Answer:
The correct answer will be option-A.
Explanation:
During anaphase, the spindle microtubules help the segregation of the chromosomes from the center of the cell at the metaphase plate.
These microtubules get attached to the chromosomes at kinetochore which helps in pulling of the chromosomes to opposite poles. The microtubules pull apart the sister chromatids when cohesin proteins degenerate.
The chromosomes do not show jiggling movement at the metaphase plate and thus, option-A is the correct answer.
Answer:
Semiconservative replication describes the mechanism of DNA replication in all known cells. ... This process is known as semi-conservative replication because two copies of the original DNA molecule are produced, each copy conserving (replicating) the information from one half of the original DNA molecule.
