Phlebotomy is a technique in which a needle is temporarily inserted into a vein to provide venous access for venous blood sampling. [1, 2, 3] Veins have a three-layered wall composed of an internal endothelium surrounded by a thin layer of muscle fibers, which in turn is surrounded by a layer of connective tissue.

Its my pleasure to help over and out : )

Answer:D.D.) Suspend the cells in liquid agar culture and monitor which culture continues to grow.

Explanation

Options A-C are correct except D.

→Increase in Telomere length is indicative of abnormal growth, cancer cells can reactive telomerase to increase cell's length.

→Once a monolayer is reached; this a stage of a complete normal cell division , a cell that goes beyond this stage must be mutated. assuming all other factors are constant .

Uncontrolled cell division is an indication of virulent growth in mutated cells.

Cancer cell requires a ,medium of living host to thrive, alga medium will not support growth for carcinoma cells -the correct answer.

Completed Que.

Secondary metabolites are toxic chemicals in plants that are not used in or derived from photosynthesis or respiration. What are

Anuta_ua [19.1K]

Explanation:

Metabolites are the different kinds of the substances which are essential to metabolism of the organism.

Metabolites produced by the plants can be categorized into the primary metabolites and the secondary metabolites.

The primary metabolites have important role in survival of plant and play an active role in the respiration and the photosynthesis.

On the other hand, the secondary metabolites are not involved in normal growth and the development of plant. Although absence of these type of metabolites can lead to impairment of survivability of plant in long run.

Secondary metabolites are produced mostly by the plants for the defense purposes. They include steroids, alkaloids, phenolics, essential oils, resins, tannins, lignins, flavonoids, etc.
