Answer:
Covalent bonding is usually exhibited when the electronegativity difference between two atoms is 1.1
Explanation:
The electronegativity difference identifies the type of bonding (i.e. covalent bonding and ionic bonding) between two atoms.
Covalent Bonding is the type of chemical bonding that form by the sharing of electron pairs between two atoms.
Ionic Bonding is the type of chemical bonding that form by the complete valence electrons transfer between two atoms.
Electronegativity is the force with which an atom attract shared pair of electrons towards itself.
The formation of covalent bond occurs when the electronegativity difference (ΔEN) between two atoms, sharing electrons with each other, is less than 1.7 which means that the atoms, having covalent bonding, do not have strength to transfer electrons towards themselves. If the electronegativity is greater than 1.7 then ionic bonding exist between two atoms because they have enough strength to transfer electrons towards themselves.
Answer:
A mutation is a heritable change in the genetic material of an individual. The change can be large or small. Large changes involve the loss, addition, duplication, or rearrangement of whole chromosomes or chromosome segments. Mutations can affect an organism by changing its physical characteristics (or phenotype) or it can impact the way DNA codes the genetic information (genotype). When mutations occur they can cause termination (death) of an organism or they can be partially lethal.

Explanation:
Since the new moon is behind the earth, It is sun, earth, moon
The Earth, Mars or Jupiter should be denser than the Sun. Density is defined by mass and volume — components of object or matter. Although the sun is huge, it’s component is made up of mostly gas (hydrogen and helium). While Earth, though smaller than the Sun, contains heavier elements such as iron, sulfur, rocks, sediments, granite, basalt and water. Mars (composed of rocks and nutrients) and Jupiter (contains gases and compounds) as well are denser when compared to the Sun’s density. Referencing to our basic understanding of matter: solid and liquid should be heavier than gas.
