Answer:
B is the answer of this question
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:
In RNA (ribonucleic acids), the nitrogen bases are:
- Adenine
- Guanine
- Cytosine
- <em>Uracil</em> (there is thymine in DNA, but not in RNA)
The bases pair like:
- Adenine (A) with Uracil (U)
- Cytosine (C) with Guanine (G)
So, the base pairs for RNA are <u>A with U </u>and <u>C with G</u>
In the state of Kansas, people are poaching deer. One example is of a man named Tim Donges. He saved up money to buy land in Kansas. He is an avid hunter, and had hunted in numerous states over the years. He described in a news article about waking up hearing rifles,being outside with family on Thanksgiving with bullets from poachers ricocheting off his barn. He found deer carcasses in his field with their heads cut off for their trophy antlers. In Kansas, the fines can be up to $50,000 and jail time.
