Answer: DNA condenses into chromosomes.
Explanation: Chromatin carefully packs these DNA molecules into stringy-looking structures called chromosomes. If the DNA molecules in cells were not snaked around histones, the molecules would be 6 feet long when placed end-to-end, according to the National Human Genome Research Institute.
Mitosis ends with 2 identical cells, each with 2N chromosomes and 2X DNA content. All eukaryotic cells replicate with mitosis-except germline cells that undergo meiosis to produce gametes (eggs and sperm)).
The correct answer is Option (B) Habituation.
Crocodiles ignore the birds which clean their teeth instead of eating them. This is an example of habituation.
<h3>Why do crocodiles show habituation toward the birds which clean their teeth?</h3>
It's an evolutionary phenomenon that when a bird used to sit in a crocodile’s mouth, the crocodile didn't eat it, instead, the crocodile used to allow the bird to sit in the mouth and clean the teeth of the crocodile so that they can alive longer, whereas the birds could get the free food from the crocodile’s mouth. It is an example of the symbiotic relationship between the two.
So, the same is the case today, crocodiles are habituated to the fact that the birds will clean their teeth so instead of eating them, these birds are being ignored by the crocodiles.
