Number 1
Explanation:
The first diagram represents the electron configuration of a carbon dioxide molecule.
Carbon dioxide as gaseous covalent molecule made up of two oxygen atoms and one central carbon atom:
CO₂
Carbon dioxide has linear structure with a bond angle of 180°.
In carbon dioxide, the atoms are covalent bonded.
The central atom is carbon and it joins up with two oxygen atoms.
The carbon has 4 valence electrons that goes into bonding in pairs. The oxygen atom has 6 valence electrons.
In order to complete their octet, they share their outermost electrons in the manner shown in the first diagram.

Answer and Explanation:
The interphase is the previous step before mitosis occurs. The interphase is conformed of the G1, S, and G2 stages.
- During the G1 stage, it occurs a high intense biochemical activity. The cell duplicates its size, and the organelles and other molecules and cytoplasmatic structures duplicate too. Some structures, such as microtubules and actin filaments, are synthesized from zero. The endoplasmic reticulum increases in size and produces a membrane for the Golgi apparatus and vacuoles, lysosomes, and vesicles. During this stage, the pair of centrioles separate, and each centriole duplicates. Mitochondria and chloroplasts also replicate.
The stages S and G2 follow the G1. Once the whole interphase is completed, mitosis occurs.
- During the S stage occurs the DNI replication process. At this point, it also occurs the synthesis of histones and other associated proteins. This is the only stage where the DNI molecule is replicated.
- G2 stage is the final one before the cellular division. Here it begins the slow process of DNI condensation. Duplication of centrioles completes. Structures such as spindle fibers are assembled.
