A scientist is studying two types of worms. Worm X has DNA identical to its parent. Worm Y has a
combination of DNA from two parents. The scientist
determines that one of the worms has a survival
advantage over the other worm.
Which statement correctly summarizes this
conclusion?
Worm X reproduces asexually, which gives it
genetic variation
Worm Y reproduces sexually, which gives it genetic
variation
Worm Y reproduces asexually, which gives it more
DNA.
Worm X reproduces sexually, which gives it more
DNA.

2. Worm Y reproduces sexually, which gives it genetic variation.

Explanation:

Worm Y was born sexually from two parents meaning it has DNA from both parents giving it a better chance at surviving. Worm X was born asexually giving it identical DNA to its parent. Worm X is only going to be able to live in one habitat.

I also got it right on the quiz.

what is the aerea shown

explanation:

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
