AES has a larger block and key length compared to DES. If we
ever had to do multiple encryptions with AES because we had
computers fast enough to brute force a 128-bit key, would we need
to move to Two-AES or Triple-AES?
A number of different vertebrates have adaptations for diving.
For example, the structure of the cardiovascular and respiratory
system of amphibians (frogs/salamanders) allows them to bypass
their unventilated lungs. Compare the structure of the amphibian
respiratory and circulatory systems to that of humans and explain
how the organization of the amphibian’s circulatory and respiratory
system are adapted to diving.
“Larger hospitals in South Florida display higher readmission
rates and thus lower quality of care compared
to smaller hospitals.”
A). Identify the implied dependent and independent
variables.
B). Does the headline demonstrate a positive or negative
correlation between the two?
C). Is there a plausible mechanism (confounding factor)
through which we could explain why the independent variable has
a
causal impact on the outcome?
D). Now try to think of reasons why this could be a spurious
relationship instead and...
In the desert there are plants that have adapted to the sparse
rainfall by evolving mechanisms to store water. Cactus are an
example of such a plant. You are studying a particular species of
cactus in an area of desert that is 100 km^2. In your designated
area of study you have counted 175 plants. What is the density of
this type of cactus in terms of plants per square kilometer?
571.4 plants/km^2
0.571 plants/km^2
1.75 plants/km^2
0.00175 plants km^2...
Mammals, birds and insects have the ability to produce urine
that is hyperosmotic to their bodily fluid; however, insects
utilize a more simplistic mechanism. In addition to the final
product being the same, there are other stages of urine formation
in mammals and insects that is quite similar. Explain
