Memory can be improved by using a variety of techniques. Describe each of the techniques listed below and explain its use throug
Aliun [14]

Answer: EDG

Explanation:

First, effortful processing is encoding that requires attention and conscious effort. This would be something like studying where you store facts in your mind for use later. Automatic processing on the other hand, is unconscious encoding of incidental information and of well-learned information. For example, I know what someone means immediately if they say it's noon. As for chunking, it is organizing items into familiar, manageable units. One perfect example would be my phone number. There are many different numbers, but its easier to manage when some are grouped together. Then there are mnemonics which are memory aids, especially those techniques that use vivid imagery and organizational devices. For example, I use the first letter technique (PEMDAS) to help me when solving math problems. Spaced or distributed practice is studying or processing with breaks to help understand concepts. For example, when I study, I take a five minute break every 20 minutes to help my brain cool down and be ready to learn more. Now, deep processing involves elaboration rehearsal which involves a more meaningful analysis. For example, giving meaning to different words or images and making them relatable.

DochEvi [55]
<h3>Answer:</h3>

Enzymes functions in a specific temperature range.

<h3>Explanation:</h3>
  • Enzymes are biochemical catalysts whose function is to speed up the rate at which chemical reactions occur.
  • Enzymes work best at a specific range of temperatures known as optimum temperature.
  • Low temperatures below optimum levels deactivate the enzyme and thus lowering the rate of enzyme activity.
  • Extreme temperatures, on the other hand, denatures the enzyme altering enzyme's active sites making it difficult for substrates to fit.
