Answer:
The correct answer will be- placebo effect
Explanation:
In the given question, the experiment was performed to test the effect of a new drug on humans in which the new drug was given to the experimental group but a non-effective drug to the control group.
This type of study on the control group is known as the placebo effect in which the treatment is provided not on the basis of the drug but on the belief system that the provided drug will treat the problem.
In the given question, the people of control group believed that they received the real treatment which is not the case. Thus, they were provided with the placebo effects.
Thus, the placebo effect is the correct answer.
This pertains to the structure of proteins. Secondary structures are stabilized by the presence of hydrogen bonds. The common types of secondary structures of proteins are the alpha helix and the beta sheets, each performing different functions.
Primary structure of protein is the peptide molecule comprised of peptide bonds. Once these peptide grows long enough, it will either be arranged into alpha helices or beta sheets stabilized by hydrogen bonds and this is the secondary structure. Once there is protein folding involved in the secondary structure of protein, then the folded protein is called the tertiary structure (or a protein subunit). When protein subunits come together to perform a specific function, then that is the quaternary structure.
Attached is a figure concerning the protein structures.

29. answer 3
30. answer 2
<span>C. Cells, Tissues, Organs, Organ Systems
The answer is C. Cells are the fundamental unit of life. Without them, life would not possibly exist. Well that is according to the cell theory, which states that cells are the basic unit of life, cells came from pre-existing cells and cells make up living organisms.
