Answer: A large region of interconnected ecosystems.
Explanation:
Biome is an ecological community that is located in a geographic area which exhibit the habitat for a specific species. A biome can be composed of many ecosystems. For example, aquatic biome may contain distinct ecosystems such as kelp forests and coral reefs.
On the basis of the above description, A large region of interconnected ecosystems.
Answer:
Trees soak up rain from the ground and store/use it. Without trees to soak up the water on the ground, it stays put > pools > floods.
Also, a little bit of rain stays on the trees' leaves. This may not seem like a lot, but there are many trees in a forest with many many leaves all holding water :)
Explanation:
B. It helps the cell absorb as many different molecules as possible
C. It is better for the cell if most molecules are prevented from entering
D. Transports protein only allow enzymes to pass through the membrane
It is better for the cell if most molecules are prevented from entering.
The cell membrane, therefore, has two functions:

c. Water leaves the sucrose solution because the sucrose molecule is a disaccharide and thus larger than the monosaccharide glucose.
d. The sucrose solution is hypertonic and will gain water because the total mass of sucrose is greater than that of glucose.
e. After the sucrose dissociates to two monosaccharides, water will be osmostically drawn to that side of the membrane.
Answer:
a. Nothing happens because the two solutions are isotonic to one another.
Explanation:
Two solutions of the same molarity are separated from each other by a membrane that allows water molecules but not the glucose or sucrose to move across it. Movement of water across the selectively permeable membrane occurs only when two solutions have different concentrations of solutes. In that case, water moves from a hypotonic solution towards a hypertonic solution. Since both sucrose and glucose solutions have the same tonicity, there would not be any change in the solution.

Answer: The correct answer is- b) Mosquitoes.
R- selected species are those species that can survive in unstable, unpredictable environmental conditions and produce large number of small size offspring. These offspring have low survival rate ( short life span) and do not have any parental care.
These species grow very rapidly and attain reproductive maturity at early stage in their lives.
Example of R- selected species- Insects ( such as mosquitoes), rats.
On the other hand, a) , c), and d) are K selected species. They survive under stable environmental conditions and produce large size offspring with very few number. They have long life span and experience parental care
Mosquitoes are an R-related species.
Further Explanation:
The fitness of a phenotype determines whether it gets naturally selected or not. For a condition where the environment of each year changes and the adaptability of the phenotypes are different for a different environment, the oscillating selection might occur in which different phenotypes are favored at different times and different environmental conditions.
Fitness can be attained by two different approaches, namely:
How much a system can invest in one approach at the cost of others depends on the environment. This type of selection is known as R-K selection. In K-selection, the organism matures slowly and has a long life span. In R-selection, the organism produces many copies of progeny in an unstable environment. Mosquito, mice, and rabbits are an example of R-species.
Some features of R-species are:
