Answer:
B.) Diffusion
Explanation:
Since this is oxygen, not water, and it is going from an area of high concentration to low, it is moving with its concentration gradient, it would be diffusion. If it were water, not oxygen, then it would be osmosis, and lastly, if it were moving from an area of low to high concentration, that would be active transport. Semipermeability is a characteristic of cell membranes, not a method of movement.
Answer:
fast- flowing areas usually contain more oxygen than slow-flowing ones.
Explanation:
looking at the statement that accurately compares fast-flowing and slow-flowing areas of stream and water, we need to understand how they flow. a stream flow downhill and it can also flow in a perfect channel, except when flooding occurs and water overflows its channel and spread out across the area of the land. so, fast-flowing generally have higher levels of dissolved oxygen more than slow-flowing because slow-flowing are aerated.

Founder effect or population bottleneck refer to events which bring about reduction in the genetic variability of a particular specie population. Such events typically drastically reduce the gene pool of the population and produce a smaller number of population with less genetic diversity. An example of a population bottleneck is a genocide event. Such event will destroy a large percentage of the affected population leaving only a smaller population with less genetic diversity. i hope these helps.
