For the first page: These adaptations are advantageous. For example, the dart frog’s bright colors warns predators to stay away from them. This will help them survive because they will not be bothered by any predators. Because the Hosta lives in such a crowded environment it is to its advantage that it has big leaves to get as much sunlight as possible. This makes it more likely to survive than other plants. Both of these advantages help the living thing to be stronger.
For page 2: These adaptations are advantageous. The Toucan has a long and narrow beak that helps it get fruit other birds cannot get. This gives them access to more food which can help them outlive other birds. The Monstera plant has adapted so that it does not mold. This helps it stay healthy whereas other plants may grow mold. These two organisms have adapted so that they have one sure advantage that will help them live longer than other species. The advantages are different but they both serve the same purpose.
The answer is D. Cold. A cold front is defined as a transition zone where cold air replaces warm air.
Answer:
The answer is D.
Explanation:
The scientific theory is a statement or explanation that is given for a natural occurance of an event which can be observed, tried repeatedly to verify it's results and turned into a theory from a hypothesis.
The option D given in the question on the scientific theory is not correct because theories are not accepted as explanations for natural events and they are also not accepted without experiments that yield the same results repeatedly.
The statements given in options A, B, C and E can be regarded true with respect to the scientific theory.
I hope this answer helps.
Answer:
Option B . Chemosynthesis and Marine snow.
The biggest issue would probably be number I. The other concerns (II, III, IV, V) would probably be easy to solve with the some specific chamber characteristics.
The fact that the moon has no atmosphere it means that it doesn't retain neither

nor

. Even with the appropriate chamber characteristics to retain such gases, how would the crop in the first place have so much free

to use.
Temperature could be managed inside the chamber as well as accelaration. The period of day light would be long and intense. As for the water, once plants evaporate water when they breath at night (instead of doing photosynthesis), that water could be all collected and condensed by the chamber to be used again during the day light period.
