Answer:

A: It is wrong to form a theory that cannot be disproven because the whole point of a theory is to test the theory and prove it.

B: Wisdom Teeth are considered to be a vestigial trait because it is passed along in genetics of humans and is a almost a 100% chance of occurrence.

C: This bird could fly because fossils and research has shown that this creature had similar bone structure to a common day bird.

D: This does not invalidate evolution because many geographic events can happen that may alter the positioning of these fossils like: Any type of corrosion or weathering, or maybe ancient civilization have dug up these fossils and then they were reburied.

Answer:

the point of science is to disprove hypothesis so having a hypothesis that doesn't allow that to happen is not good science

2. they don't fit in our mouths so are a trait from when we had larger jaws

3. bones of your lower jaw, middle ear and voice box (they aren't actually gills fyi, they just look like them)

4. likely yes as their bones were hollow but likely only able to fly short distances, the thought was that they couldn't do their size and weight but with hollow bones they were able to like a quail would

5. no because they could be sister taxa, you would have a hard time proving exactly that this new fossil is the common ancestor that birds came from to replace the old hypothesis (guess) of which one did.

KengaRu [80]
Phat1 = 9/142
Phat 2 = 5/268
Phat 3 14/410
Test statistics = (Phat 1 - Phat 2) / (Square root of (phat × (1- phat))
times the square root of (1/n1 + 1/n2))
Test statistics = 2.373
P- value = 2× (1- normal cdf (2.373, 0, 1)) 
= 0.0176
At the level of significance, there is difference between the proportion of drug-resistant wihtin the two states.
