When there is a cut on your skin, it gives bacteria and other organisms a gateway to enter directly into your bloodstream and could harm the body. By cleaning the wound, you prevent disease and infections from the bacteria.
The ovaries contain the female gamete cell, called the oocytes. In non medical terms, the oocyte is called the “egg”. The ovaries are filled with follicles. Follicles are fluid-filled structures in which the oocyte (also called egg) grows to maturity.
The cytoplasm is the name given to everything enclosed by the cell membrane, except the nucleus.
The cytosol is the aqueous portion of the cytoplasm which contains ions, small proteins, ribosomes, metabolites, and water.
Everything present in the cytoplasm except the membrane-bound organelles makes up the cytosol.
Answer:
The correct answer is "The "host range" for a virus is determined by the presence or absence of particular components on the surface of a host cell that are required for the virus to attach".
Explanation:
The missing option of this question is the one that is correct, which is "The "host range" for a virus is determined by the presence or absence of particular components on the surface of a host cell that are required for the virus to attach". A virus is able to infect by recognizing particular components that are present in the surface of the host cell. If this components are absent in the cell, the virus is not able to infect it. Therefore, the "host range" is determined by the presence or absence of this particular components.
The presence of hydrogen bond is one factor that explains the fact that ice floats over water because it has less density.
Due to this, rivers and lakes freeze from the surface whereas it is in liquid state at the bottom which allows the sea animals to survive even in colder temperatures.
Water makes up at least 70% of earth and 65% of our bodies and this property of water is essential for our lives as it maintains the survival.
