The right answser is Chromosomes.
After DNA replication during cell cycle interphase, the chromosomes are composed of two identical chromatids attached at the centromere. Each chromatide is formed of a molecule of DNA (the nucleofilament) associated with proteins, the histones, around which it winds to form nucleosomes. At the ends of each chromatid are telomeres, consisting of repetitive DNA sequences that provide protection for chromosomal endings. Telomeres and centromere do not encode genetic information, it is non-coding DNA.
Answer: =<u>Convergent</u> evolution
Explanation: <u>Convergent</u> evolution occurs when organisms share a trait that originated in an ancestor but changed over time in different populations.
From smallest to largest: Planetesimals to protoplanets to moon to planet.
A planetesiamal is a small body from which planets originate. When planetesimals joins together they become protoplanet. An aggregation of protoplanets will become a moon or a planet. Moons are always smaller compared to the planet they orbit.
The correct answer is option C, that is, epoch.
An epoch refers to a time unit. An epoch in geological time scale refers to a subdivision, which is lengthier than an age but briefer in comparison to a period. The present epoch is the Holocene epoch of the Quaternary period.
The two or more periods form a geological era, two or more eras form an eon and is the largest division of the geologic time.
