7. The correct answer is photosynthesis.

Autotrophs are organisms which produce food for themselves-from simple to complex molecules. In the case of photosynthesis, producers (plants or some algae) use the light energy to produce complex organic compounds (carbohydrates, fats, and proteins).

8. The correct answer is primary consumers.

Since the pioneer species are usually autotrophs because there is no other source of energy except light energy in the early stages of succession (after the eruption). Most likely, the primary consumer will appear next because they feed upon producers.

9. The correct answer is: they are different populations of fish.

Those two different kinds of fish have unique adaptations that enable them to survive and live in distinct environments. It is most likely that molecular changes underlie adaptation and speciation of those fishes.

How does the adaptation help the animal survive and reproduce?<br> Giraffe

GarryVolchara [31]

(A)An adaptation is a characteristic that helps an animal survive in its habitat. All animals must be able to obtain food and water, protect themselves from harm, withstand the climate, and reproduce young so the species doesn't become extinct. ... Without their adaptations, the species could not thrive in that environment.
GIRAFFE-That ability – coupled with the tongue's impressive reach and its tough skin – allows giraffes to selectively browse, plucking leaves from among the nasty thorns brandished by many of its preferred food trees, such as acacias.

Answer: water will move out of the animal cell causing it to swell and burst (Option C)

Explanation:

When a cell is immersed into a salty solution, the osmotic pressure generated by concentration differences of salt, will make the salt come in due to cell self-protection mechanism of the cell and water will come out, eventually the cell can burst .But since the animal cells has a higher concentration of salt and the solution has a lower concentration osmosis will take place and salt will move from higher salt concentration to lower.

The answer is C. If you want a good experiment on this place an egg in a glass of vinegar for 6 hours, remove and place into corn syrup for 6 hours, and finally remove and place into water for 6 hours. you’ll get a really good example of osmosis in different stages.

I think this is what you're asking.

Examples of Inherited Traits:
Attached or Free Earlobe. If you look closely at your earlobe, it might be a smooth line, or slightly dangly (free).

Allergies. The most common one I think is gluten.
