Social cognitive theory proposes that changing a behavior is a function of individual characteristics. True or False
sertanlavr [38]

Answer:

The answer is: False.

Explanation:

Social cognitive theory stands that portions of an individual's knowledge acquisition can be related to <em>observing others within the context of social interactions. </em>

When people observe a model performing a behaviour and the consequences of that behaviour, they remember the sequence of events and <em>use this information to guide subsequent behaviors</em>.

The theory says that people do not leatn new behaviours solely by trrying them and either succeding or failing, but upon the replication of the action of others.

I hope it works!

What is the minimum number of cycles necessary to replicate a fragment of DNA over 500 times? How did u determine this?
ryzh [129]

Answer:

The correct answer is "9 cycles".

Explanation:

The minimum number of cycles necessary to replicate a fragment of DNA over 500 times is 9 cycles. In Polymerase Chain Reaction (PCR) method, the fragments of DNA are doubled in each cycle. This means that after "n" cycles, the total number of fragments is given by the equation 2^n. In this case, after 9 cycles a total of 512 DNA fragments will be obtained, because 2^9 is equal to 512.
