Petri dishes should be incubated with the lid side up. True False.

Answers

Answer 1

False. Petri dishes should be incubated with the lid side down to prevent condensation from forming on the lid and potentially contaminating the culture.

When incubating Petri dishes, it is important to place them with the lid side down. This practice helps prevent condensation from accumulating on the lid and dripping onto the agar surface, which can introduce contaminants and compromise the integrity of the culture.

Incubating the Petri dish with the lid side down allows any condensation that forms inside the dish to settle on the lid rather than coming into contact with the agar. This helps maintain a sterile environment and minimizes the risk of contamination.

In addition to preventing contamination, incubating Petri dishes with the lid side down also helps maintain the proper moisture levels within the culture. Placing the lid side down creates a humid environment inside the dish, which can be beneficial for the growth of certain microorganisms.

Overall, to ensure the success of cultures and minimize the risk of contamination, it is recommended to incubate Petri dishes with the lid side down during the incubation period.

Which of the following physiological functions is not usually served by proteins? A. Catalysis B. Energy reserve. C. Structural support. D. Defense

Answers

Among the options provided, the physiological function that is not usually served by proteins is B. Energy reserve.

Proteins primarily serve as catalysts (enzymes) for biochemical reactions, providing catalysis (A), such as facilitating chemical reactions in the body. They also play a crucial role in structural support (C), forming the building blocks of tissues and organs. Additionally, proteins are involved in defense mechanisms (D), such as antibodies that help fight against pathogens and foreign substances.

However, proteins are not typically used as an energy reserve (B) in the same way as carbohydrates and fats. While proteins can be metabolized for energy under certain circumstances (e.g., during periods of starvation or intense exercise), their primary role is not as an energy storage molecule. Carbohydrates and fats are the main sources of energy reserves in the body.

in the elaboration likelihood model of persuasion the central route

Answers

In the elaboration likelihood model of persuasion, the central route is a process that involves a high level of cognitive processing. The central route is characterized by a person's motivation to think critically and analytically about a message in order to make a decision.

This process involves the evaluation of the message's arguments, evidence, and logic, as well as the person's own beliefs and values. The central route is most effective when the message is relevant to the person's life and the person has the ability and motivation to process the message in a detailed and thoughtful manner. A message that is processed via the central route is more likely to result in long-lasting attitude change.

On the other hand, the peripheral route is a process that involves low-level cognitive process. The peripheral route is characterized by a person's reliance on superficial cues, such as the speaker's appearance or the use of humor or emotion, rather than on the message itself. The peripheral route is most effective when the person is not motivated or able to process the message in a detailed manner. Therefore, the peripheral route is more likely to result in temporary attitude change.
