Answer:
Total blue ribbon required = 1900 cm or 19 meter
Given:
Each costume required = 38 cm ribbon
Number of costume = 50
Find:
Total blue ribbon required
Computation:
Total blue ribbon required = Each costume required × Number of costume
Total blue ribbon required = 38 cm × 50
Total blue ribbon required = 1,900 cm
Total blue ribbon required = 1900 cm or 19 meter
Answer:
humans killing whales caused orcas to have to eat otters which caused sea urchin populations to increase which caused kelp populations to decrease
Explanation:
Answer: Yes
Even if there is an abundance of fish in the oceans, and that even if the general rule is that big things eat smaller things, it is not true with the <span>orca population (whales). Whales depend on chinook salmon for survival, and truly, the hypothesis that the lack of chinook salmon negatively affecting the orca population is true.</span>
<span>However, for a hypothesis to become lifted to the ranks of a theory once it passes a series of tests. Other scientists may claim its correctness, other may oppose to it. So there is a need to </span><span>differentiate between the hypothesis on checking and competing hypotheses.</span>
Zebra mussels will take over an ecosystem and deplete resources that species indigenous to the area require to survive.
Answer:
Diffusion is the spreading of something more widely. When you drop a sugar cube in hot tea the sugar cube spreads out and the sugar starts to dissolve in the tea. Osmosis is a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one, thus equalizing the concentrations on each side of the membrane. If the concentration of water molecules ouside the cell is lower than the concentration of water molecules outside the cell then the water moves out through osmosis. Water travels through the cell membrane.
