Answer:
Acceptable Lewis structure of Diatomic Nitrogen Molecule is as follow,
:N≡N:
Explanation:
The given lewis structure is acceptable because each nitrogen atom has a complete octet and and the formal charge of each nitrogen atom is zero. So those lewis structures which has zero or least formal charges are said to be more stable and acceptable. The formal charge is calculated is,
Formal Charge = # of Valence e⁻s - [# of non-bonded e⁻ + 1/2 # of bonded e⁻]
For N,
Formal Charge = 5 - [ 2 + 6/2]
Formal Charge = 5 - [ 2 + 3 ]
Formal Charge = 5 - 5
Formal Charge = 0
Same result will come for the second N atom.
In region C the enzyme is saturated with substrate.
The fee of reaction whilst the enzyme is saturated with the substrate is the maximum charge of the response, Vmax. the relationship between the price of response and awareness of substrate relies upon the affinity of the enzyme for its substrate.
whilst all lively sites are occupied, the enzyme is saturated. At this saturation point, adding extra substrate makes no difference to the response rate.

Answer: B. The molecules move faster and become less dense
Explanation:
Liquid is the state of matter in which particles are less tightly bound as compared to solids as they have weak inter molecular forces as compared to solids.
Thus when a solid is heated, the molecules start moving in random motion due to an increase in the kinetic energy. The molecules move apart as the forces will be weak and thus less molecules will be present per unit volume. Thus it will become less dense.
Bears are omnivores (and scavengers), meaning they eat both plants and animals.
it can be both a primary consumer (if it eats plants) and secondary & tertiary consumers (if it eats a plant-eating animal). so it depends on what it eats.
Level 3 is the correct answer
