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.
Receive deoxygenated blood from the body
Explanation: If the rate of photosynthesis increases, then the number of bubbles will increase.
Answer:
the second to last one
Explanation:
BP is extremely high?? average is 120/80, also elevated temperature.
Answer:
Salt lowers the freezing point of water via freezing point depression. ... When salted ice melts, the water can't refreeze as readily because the saline isn't pure water anymore and because the freezing point is colder. As more ice melts, more heat is absorbed, bringing the temperature down even lower.
