<u>Answer</u>: Ionic bond
<u>Explanation</u>:
- An ionic bond is a type of a chemical bond formed by the complete transfer of electrons from one atom to another atom i.e one of the atoms loses its electrons and the other gains it. This results in the formation of 2 oppositely charged ions.
- In sodium chloride, sodium loses one electron from its outermost shell (valence shell) whereas chloride gains it. Due to this sodium gains, a net positive charge and chloride gain a net negative charge.
- So, due to the complete transfer of electrons that takes place from sodium to chloride, the compound generated (Sodium chloride) has an ionic bond.
Bonds between atoms break and new bonds form correctly describes a chemical reaction
<u>Explanation:</u>
The process of resetting the integral fragments of the reactants to produce diverse items as outcomes is termed as a chemical reaction. Effects transpire when pair or further particles fuse and the particles transfer. Bonds between atoms are split and designed to develop new fragments.
Chemical reactions need to be separated from physical alterations. The physical aspects of a thing will vary during physical conversion befalls, still the chemical identification will endure the equivalent. Chemical bonds are formed or split to formulate a unique molecule. Individual reactions often occur as part of a broader list of reactions.
Answer:
Presence of chlorophyll pigment in the leaves and cell walls were made of cellulose
Explanation:
The first plants that appeared on the land areas were comprised of the main component known as the cellulose that forms the cell wall of the plants and is responsible for making the various parts of plants such as branches, plant stems, and leaves, stronger and supportive.
In addition to this, the leaves of these primitive plants were comprised of green pigments known as chlorophyll that absorbs the sunlight and CO₂, and helps the plants in preparing the food for themselves as well as for the consumers, and also liberates oxygen (O₂) with it.
Thus, these are the two common characteristics that supported the idea that the primitive land plants had a relation with the green algae.
On the planet earth. They exist in what we call the "world", which holds all seen life.
