Answer:

The correct option is <em>B) ultraviolet region, especially below a wavelength of 320 nm.</em>

Explanation:

Ultraviolet light carries an enormous amount of energy in it. It is invisible to the human eye. When UV light with enormous energy and wavelength lesser than 320nm, hits the DNA, it causes changes in the structure of the DNA. Mostly, it affects the thymine nitrogenous base regions and forms pyrimidine dimers. The structure of the DNA changes on all the sites where dimers form and hence, they cannot be properly transcribed.

Answer:

Patrick's hypothesis was "If fish eat microwaved food, then they will swim faster through the maze."

The fish that are in the control group are the fish without microwaved food.

The independent variable is the microwaved food.

The dependent variable was the time it took for the fish to swim through the maze.

Patrick's conclusion should be that the special food did not seem to make a large difference in helping the fish become faster, since 8 out of 10 fish were faster in both special food and regular food groups.

Charra [1.4K]

Answer:

Any of the answers are correct. This question is completely opinionated (I chose no).

[If you limit your interpretation of the biological species concept to only what happens in nature, lions and tigers are separate species. In contrast, if you consider what is possible with human intervention, you could argue that lions and tigers are not separate species since they can be crossed to form fertile ligers.

The biological species concept is one of over 20 different species concepts that attempt to put nature into human-constructed categories. Most biologists would agree that the challenge of defining species has still not been elegantly solved.]
