A type of cellular transport is shown. Which description best identifies this type of cellular transport? Your answer: A.Osmosis
madreJ [45]

Answer:

B.Active transport, because energy is being used to move molecules against the concentration gradient

Explanation:

Substances move in and out of living cells through various transport means. Some substances move passively (without energy) while others move actively (with energy). Active transport of substances involves the movement of molecules against the concentration gradient.

Active transport moves against concentration gradient in the sense that the movement occurs from a region which is less concentrated to one which is more concentrated, hence, energy input in form of ATP is required for such transport to occur. This is the case of the cellular transport in the diagram. Therefore, it is an ACTIVE TRANSPORT because energy input (ATP) is required.

Note, Osmosis and facilitated diffusion are types of passive transport that requires no energy to occur.

Give two examples of stimuli that are conditioned reinforcers but not tokens. Explain why they are conditioned reinforcers, and
m_a_m_a [10]

The conditioned reinforcers known as tokens can be accumulated and traded for different reinforcers.

Any two suitable examples, such as a compliment, an invitation to dinner, the presence of a loved one, or a warm greeting are all suitable examples. These are all conditioned reinforcers since they are connected to stronger reinforcers. They cannot be accumulated and swapped for different backup reinforcers, hence they cannot be considered tokens.

What is backup reinforcer?

Backup reinforce is a reinforcer that serves as the foundation for a conditioned reinforcer. It is a reinforcer in a token system for which tokens can be traded in order to keep their reinforcing properties. For instance, poker chips can be converted into cash at the conclusion of a game of poker. The money serves as a secondary reinforcer in this situation. It is allowed to use any two relevant examples.
