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

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.

Outline three examples of cycles of inorganic nutrients. For each, outline the uses of the nutrients in living organisms, its me
Serggg [28]

The three examples of cycles of inorganic nutrients are Nitrogen, carbon and sulphur cycle.

Nitrogen is required to make amino acids and DNA in organisms. Carbon is the main component of glucose through which organism make energy, about 18 per-cent of the human body comprises carbon. Sulphur is an important constituent of some proteins, amino acids and enzyme cofactors.

Explanation:

The biogeochemical cycles like the nitrogen cycle are responsible for converting nitrogen into many chemical forms as nitrates, nitrites, ammonia. This process involves degrade decomposing animal and plant matter and naturally cleaning the environment also nitrites and nitrates become biofertilizers. The plants take nitrogen through their roots and in turn primary consumer in food chain ie. organisms consume the plant and eventually releases nitrogen as a waste material, dead and decaying body to the soil and cycle goes on.

In the carbon cycle the carbon is exchanged from the atmosphere to the organisms and then again to the environment. Plants perform photosynthesis by using carbon dioxide, primary consumer eats it and gets nutrition to perform cellular respiration, in turn, gets energy which gets dissipated and stored as biomass eventually in the course consumer die and replenish the soil with carbon. The Carbon emitted will keep cycling through air, water and soil.

The sulphur cycle involves the movement of sulphur between rocks, water and living beings and plants. Plants ( producers) absorb sulphur dissolved in water and animal consume these plants to replenish their sulphur requirement. And when organism die, sulphur enter the cycle again.

There will be a transfer of these inorganic nutrients to the trophic level in food chain.

How are the two location different in regards to food/drink religion, customs etc?
Natali [406]
<span>Two locations can differ in their food, religion, customers, based on their heritage. Much of the time, the history of a nation often determines where it stands today. Examples include Great Britain. A nation that always had a singular ruler and even in today's age, there is a King and Queen, something that is not often seen among other nations.</span>
