Antibiotics are designed to target only the cells that are harmful to the human body
Answer:
B)attach specifically to host cell receptors
Explanation:
Viral spikes are one of the envelope proteins. These proteins are coded for by viral genes. Viral spikes project from the envelope surface. They are also called peplomers. One of the functions of these spikes is to specifically interact with the receptors present on the surface of the host cell to mediate the attachment of the virus to the host cell surface. Viral spikes and the host cell surface receptors are complementary to allow their specific binding. For example, the spike protein of the SARS-coronavirus bind specifically to the human host cell receptor ACE2.
Answer:
The statement is true
Explanation:
Asepsis means the absence of infection-causing germs and surgical asepsis means the absence of all the microorganisms or spores in any invasive process.
Surgical asepsis is usually used medical procedure when a foreign object is used to insert into the patient body which can open a transmission route of infection causing germs into the patient body. For example, using a catheter in patients.
So surgical asepsis is important to avoid any type of infection in the patient during his treatment. So the statement is true.
Answer:
Eutrophication
Explanation:
Eutrophication is the name given to the natural nutrient enrichment of a shallow lake, estuary, or slow-moving stream. It is caused mostly by runoff of plant nutrients, such as nitrates and phosphates, from surrounding land.
