Ipatiy [6.2K]

Phagocytosis of microbes by macrophages is enhanced by both the binding of antibodies to the surface of microbes & antibody-mediated opsonization of microbes

What is the function of phagocytosis?

Phagocytosis is the cellular process through which particles bigger than 0.5 m in diameter, such as bacteria, foreign substances, and apoptotic cells, are ingested and eliminated.

  • Phagocytosis is found in many different types of cells and is hence an important step for tissue homeostasis.
  • However, only specialized cells known as professional phagocytes are capable of high-efficiency phagocytosis.
  • Among these specialized cells are macrophages, neutrophils, monocytes, dendritic cells, and osteoclasts.

Phagocytosis occurs in four stages:

I identification of the particle to be swallowed,

ii) activation of the internalization process,

iii) development of a specialized vacuole known as a phagosome,

iv) maturation of the phagosome to turn it into a phagolysosome.

Hence, the correct option is A

A negative control is a sample that you know will give you a negative result. You are testing for the presence of proteins, redu
lbvjy [14]

Answer:

Starch and water will be the best negative control

Explanation:

Negative control sample is a sample that will not give change in an experiment.

Starch and water will be the best negative control. This is because, starch is broken down by HCl to monosaccharides in the Benedict test which is the test for reducing sugar

Distilled water remain a negative control because it remain blue which means it does not reduce sugar with starch solution.

Water plus us a negative control for Buiret test (protein) and Benedict(reducing sugar) because it does not indicate the presence of protein and reducing sugar.
