Scientists are testing a new drug, which they think might allow people to memorize large amounts of information. group a is taking a sugar pill. group b is taking the new drug. both groups are 25â35 years old and are not taking any other medicine. after a month, both groups will be given a memorization test, and scientists will compare each groupâs ability to memorize new information. which choice is the independent (manipulated) variable?
a.
the sugar pill
b.
the new drug
c.
the ability to retain short-term memories
d.

Give your knowledge of these things in your paper, you will compare and contrast analog and digital signals to determine which is more reliable for encoding and transmitting information. youâll compare these features: signal shape numerical values for signal measurements amount of data that can be transmitted energy requirements privacy and security (ability of the signal to be encoded in a secret code) clarity of signal in the space provided, write down what you already know about any of these features. if youâre not sure, write down questions you might have about the features.
