Answers
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.
Explanation:
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.
Explanation:
For C you can look up archaeopteryx and find an article for evidence

When ice freezes, the water around it becomes saltier and colder. _______, it's density increases.
A Therefore
B On the other hand
С In contrast
D Especially
Answers
B isn’t the correct answer to this question because you use “On the other hand” to introduce two contrasting points, facts, or ways of looking at something.
C isn’t the correct answer because we are not comparing or contrasting anything in this sentence.
D isn’t the correct answer because “Especially” is used in a formal sentence example: She can't be sure she will win, especially at this early stage of the campaign.
When ice freezes, the water around it becomes more saline and colder. Therefore, its density increases. Hence, the correct option is (A).
What is Density?
Density is defined as the mass per unit volume of a substance and is denoted by ρ, although the Latin letter D may also be used.
Density is defined as mass divided by volume: [tex]{\displaystyle \rho ={\frac {m}{V}}}[/tex]
where ρ is density, m is mass, and V is volume. It has the units of mass divided by volume such as grams per centimeters cube [tex](g/cm^3)[/tex] or kilograms per liter (kg/l).
When water changes from a liquid to a solid state that is liquid in the form of ice, its density will increase as it becomes saltier and colder.
Thus, when ice freezes, the water around it becomes more saline and colder. Therefore, its density increases. Hence, the correct option is (A).

A pelican is hunting for fish as it flies above the surface of the water. Why must the pelican alm for the fish in a slightly different place in the water than where the fish appears to be
located?
Answers
Answer:
I'm not sure but maybe because if the pelican goes exactly where the fish is the fish will naturally move forward to escape so instead of catching the fish the pelican would get a mouth full of water. If the pelican aims for a spot a little different then where the fish actually is the pelican can might catch it because the fish went to its direction. (sorry if that's not correct)

The energy from the sun is produced in the core through the process of nuclear fusion. The photons travel through the sun and are released as radiation which travels to the earth. How long does it take to reach the earth?
Answers
Answer:
8 min 20 seconds
Explanation:
Radiation from the sun travels as light through the vacuum of space. Therefore, it is travelling at the speed of light which is roughly 300,000 km/s. If we divide this speed by the average distance between the Sun and the Earth (150,000,000 km) we would get a total of 500 seconds. We can now turn this total time into minutes which would be roughly 8 min and 20 seconds. Therefore, it would take a total of 8 min 20 seconds for radiation from the Sun to reach Earth.

C.
It’s attributed to natural environmental changes.
D.
It’s necessary for evolution.
E.
It’s affecting few species.
Answers
Answer:
its b
Explanation:
Extinction is primarily attributed to human intervention. So, the correct option is B.
What is Extinction?The extinction is defined as the end of a particular type of organism or a set of types, typically a species. Although the ability to reproduce and bounce back may have been lost earlier, the death of the last member of the species is usually considered as the moment of extinction.
Extinction is the term used to describe the extinction of an entire species. In that it has allowed for the emergence of new species and the ascent of others, extinction has both advantages and disadvantages. Since most species have been driven to extinction by human activity, humans have had a significant impact on the pace of extinction. The main cause is thought to be human activity.
Therefore, the correct option is B.
