Answer:
POSITIVE CONTROL
c) Active Activator
d) Active Repressor
NEGATIVE CONTROL
f) Inactive repressor
a) Inactive Activator
b) cAMP
Explanation:
The positive controls are those groups in the experiment whose treatments are expected to confirm previously known results, thereby enabling the comparison of these results with the target group. In this case, both active activators and repressors are able to give results that can be compared with the test group
The negative controls are those experimental groups where no response is expected. In this case, both inactive activators and repressors, and cAMP (which is a secondary messenger in diverse biological processes but is not involved in this pathway), are not expected to produce any measurable response.

Answer: See explanation
Explanation:
a. A social psychologist spends the afternoon at the mall and unobtrusively records how teenagers act in groups.
This is an observation. This is because the social psychologist is gathering data about the behavior of the teenagers and recording it.
b. A positive psychologist measures the relationship between spirituality and happiness.
This is a correlational study as the relationship between two variables are being measured.
c. A health psychologist randomly assigns people to meditate in the morning, at night, or not at all. After eight weeks, people rate their overall moods.
This is an experiment. Here, the independent variable is manipulated and its effect is tested on the dependent variable.
d. A cognitive psychologist sends out a questionnaire to all incoming students to determine their computer skills.
This is a self-report survey. A survey is referred to as a self-report that is used for research purposes as information regarding people are collected.

Answer: 9 electrons
Explanation: In a neutral atom, it's important to understand that the atomic number or the number of protons that are stored in the core of that element will be the same as the number of electrons in the energy levels orbiting the nucleus.
So if an atom has 9 protons and it's neutral, the atom will have 9 electrons as well since the atomic number is your number of protons and electrons when the atom is neutral meaning it's not an ion.
