Case Studies:
Studying or recording one subject, and/or the subject's life and developments over long periods of time (sometimes over the course of their whole lives)

Surveys:
A study tool to collect data amongst several individuals in a population. May be used to find out factual information, or simply one's opinion on a certain topic.

Naturalistic Observation:
Observing subjects in their natural environments! (Like observing a child's behaviors at home, where they feel most comfortable. When observing in places where they may not be comfortable, behavior of the subject is due to change.)

  2. The number of bacteria that will be in the petty dish after 12 hours is 167818 bacteria.

<h3>What is an exponential function?</h3>

An exponential function can be defined as a mathematical function whose values are generated by a constant that is raised to the power of the argument. Mathematically, an exponential function is represented by this formula:

f(x) = eˣ

<h3>How to calculate the initial number of bacteria?</h3>

B(t) = 150e^0.585t

When t = 1, we have:

B(1) = 150e^0.585(1)

B(1) = 150e^0.585

B(1) = 269.25 ≈ 270 bacteria.

<h3>How many bacteria will be in the petty dish after 12 hours?</h3>

B(12) = 150e^0.585(12)

B(12) = 150e^7.02

B(12) = 167817.99 ≈ 167818 bacteria.

Sigmund Freud learned about his patients by conducting experiments in his laboratory.
Gnom [1K]

Answer:

This is: False

Explanation:

Freud learned about his patients using the psychoanalytical method, and not by conducting laboratory experiments. The psychoanalytical method involves clients telling the therapist about their childhood memories, dreams, desires and relationships so that the therapist can uncover the client's unconscious thoughts, feelings and beliefs that might be influencing the client's behavior and leading to mental illness.

The psychoanalytical technique involves making unconscious behaviors, thought, beliefs and emotions conscious so that clients can face them and work through them with the guidance of the therapist. Therefore Freud, sought to learn about and cure treating mental illness in his clients by working through the root cause of their- childhood experiences and traumas, unconscious patterns, suppressed feelings, etc.
