Answer:
The correct answer would be "The percentage of dark brown sea lions will increase, and the percentage of light brown sea lions will decrease".
Natural selection refers to the natural phenomenon by which organisms which are better adapted to the changing environment tend to survive and reproduce more as compared to the organisms which are less adapted.
As aquatic environment make dark brown sea lions more reproductively successful thus, the offspring of dark brown sea lions would have better chances to reach the reproductive age.
Hence, with the percentage of dark brown sea lions would increase and that of light brown sea lions would decrease.
Well a mixture you have to use ingredients to make and a pure substance you don’t need ingredients to make
With every other lever 10% of the energy with be transferred. In this case:
Primary Producers (500)
1) First- level consumer. (50)
2) Second-level consumer. (5)
3) Third- level consumer. (0.5)
Remember the formula is:
(Primary Producer) __units X 10%= __
In this case: 500 units X 10%= 50
Answer:
The career in marine biology that appeals to me the most is aquatic science. Aquatic scientists use comparative studies, long term data, models, and theory to address a myriad of questions pertaining to water: water movement, water chemistry, aquatic organisms, aquatic ecosystems, movement of materials in and out of aquatic ecosystems, and the use of water by humans. This sounds very compelling to me.
