Answer:
All living organisms are made up of one or more cells, which are considered the fundamental units of life. Even unicellular organisms are complex! Inside each cell, atoms make up molecules, which make up cell organelles and structures. In multicellular organisms, similar cells form tissues.

Answer:
C. Taking blood samples from patients for research purposes
without consent
Explanation:
Generally, providers may not render medical services without the patient’s consent, unless performance of emergency, lifesaving care is necessary. Taking samples from a patient is a type of medical service; thus, state consent laws apply. In addition, providers may not disclose PHI without patient authorization.
It depends on the definition of unethical being used, however I think I am right. I'm in AP bio currently. Let me know what the answer is :)
Answer:
a. the virus must be able to cross-link red blood cells directly.
Explanation:
Viral hemagglutination assay is a method which is used for the quantification of the relative concentration of the viruses.
The principle on which the hemagglutination assay works is as follows:
- There are sialic acid receptors present on the surface of the red blood cells which will bind to the haemagglutinin glycoprotein present on the surface of the viral particle.
- Due to the binding of the sialic acid receptors with haemagglutinin particle there will be cross-linking of the red blood cells by the viral particles and a lattice formation will take place.
- The lattice will remain suspended in the solution however if the concentration of the virus particles will be less, the lattice will settle down in the well.
Thus, this method allows knowing the relative concentration of the virus.
<em>Due to its basic principle of cross-linking this method works well for only a few viruses such as influenza virus. </em>
<span>AntiÂpsychotic drugs generally work by blocking a specific subtype of the dopamine receptor, known as the D2 receptor. This helps to regulate the functioning of brain circuits that control thinking, mood, and perception.</span>
Answer: slow down
Explanation:As Earth rotates, the Moon's gravity causes the oceans to seem to rise and fall. (The Sun also does this, but not as much.) There is a little bit of friction between the tides and the turning Earth, causing the rotation to slow down just a little. As Earth slows, it lets the Moon creep away.
