A hypothesis satisfies 4 conditions -
correct answer ✅1. Based on observations/observable
2. Testable (can be tested using available equipment and
technologies, or conceivably can be tested)
3. Falsifiable - can be proven wrong
4. Provides a plausible explanation.
COVID Omicron variant is more easily transmissible and more
contagious than its predecessor, the Delta variant; therefore, future
newly emergent COVID variants will be even more transmissible
than Omicron variant. -
correct answer ✅Not a hypothesis. Does not explain why the
Omicron variant is more transmissible.
Future newly emergent COVID variants will be even more
transmissible than the Omicron variant because COVID Omicron
variant turns out to be more easily transmissible and more
contagious than its predecessor the Delta variant. -
correct answer ✅No, still does not have a scientific explanation to
why the omicron variant is more transmissible.
Compared to normal male mice, male mice with higher
testosterone level are more aggressive toward other mice. -

correct answer ✅Not a hypothesis. A prediction. No scientific
explanation or reasoning.
Compared to normal male mice, male mice with higher
testosterone level become more aggressive toward other mice
because male rabbits with higher testosterone level show more
aggression toward other rabbits -
correct answer ✅Not a hypothesis, using other data to try and
validate the prediction but there is still not scientific explanation to
why higher testosterone levels lead to aggressive behaviour
specifically in male mice.
Which below is a prediction suited for the above hypothesis?
"Compared to normal male mice, male mice with high testosterone
level show more aggressive behaviour toward other mice because
testosterone stimulates the mammalian brain region responsible
for aggressive behaviour."
1. A male mouse that completely lacks aggressive behaviour has
lower testosterone level in its blood than normal male mice that
show some level of aggression.

2. Male mice in a crowded and highly stressful environment will be
more aggressive than male mice in a less crowded and calm
environment.
3. Highly aggressive male mice injected with chemicals that block
the effect of testosterone in their brain will become less aggressive.
4. A male mouse that shows little aggressive behaviour will become
more aggressive if injected with testosterone. -
correct answer ✅1,3,4. It is not 2 because it is claiming that
another variable, stress, is the reason for why male mice become
aggressive and not testosterone which is the variable we want to
test and vary, not stress levels.
Compared to normal male mice, male mice with high testosterone
level show more aggressive behaviour toward other mice because
testosterone stimulates the mammalian brain region responsible
for aggressive behaviour. -
correct answer ✅YES. has a scientific explanation and is falsifiable.
Based on observations and is testable.

Similarities between hypothesis and predictions: -
correct answer ✅A prediction and a hypothesis share 3 conditions
1. Based on observations/observable
2. Testable (can be tested using available equipment and
technologies, or conceivably can be tested)
3. Falsifiable - can be proven wrong
What is the difference between a hypothesis and prediction? -
correct answer ✅A hypothesis has a plausible explanation.
A hypothesis is generally phrased as
Aspect LINKED to Observation because of PROCESS. -
correct answer ✅
Aspect -
correct answer ✅something that varies or can change in the
environment, either naturally or by human manipulation. (eg. vary
testosterone levels)
