Answer:
b. A deep, narrow river divides a population of hummingbirds.
Explanation:
Hummingbirds can fly across the river. The deep and narrow river can not separate a population of hummingbirds into two patches since hummingbirds from one side of the river can fly and reach to the other side of the river.
Without any geographical isolation, hummingbirds can continue to interbreed among themselves. The continued interbreeding would not allow their reproductive isolation and thereby would prevent the allopatric speciation.
Answer:

Explanation:
First, let's identify the tools needed.
Since the biology class is studying the temperature, they will likely need a <u>thermometer</u>. Also, they are gathering information about the growth of the plants. This could use a <u>balance </u>of a meterstick.
Next, recall the difference between quantitative and qualitative data.
- <u>Quantitative</u>: Measurable and numerical results found using scientific instruments/devices
- <u>Qualitative</u>: Data found using the senses, such as descriptions and diagrams.
Since the class is measuring temperature and growth using tools, it must be quantitative data.
We can eliminate choices A and B, because they claim the class will gather qualitative data. Then, we can eliminate choice D, because a beaker and timer won't help with temperature and growth. That leaves choice C as the correct answer.
