Plant cells have all of these, but only a plant cell has a chloroplast.
Both nuclear and chemical equations are balanced according to the total mass before and after the change.
In every equation or reaction, the total mass of the reactants must be equal to the total mass of the products. In other words, all reactions - be they chemical or nuclear - must obey the law of conservation of mass.
The law of conservation of mass states that mass can neither be created nor destroyed, but can be converted from one form to another during a reaction.
Thus, in order to balance reactions involving chemical or nuclear reactants, the total mass before the reaction must be equal to the total mass after the reaction.

The nicotine indirectly inhibit the CB1 or also known as the
Cannabinoid receptor type 1, which is the one responsible in obesity and
metabolic syndrome, thus, this would explain the weight gain associated with
people who quit smoke as if this is indirectly inhibited, it produces weight
gain.
Answer:
Frogs can breathe through their skin thus it is this to allow for easy diffusion of oxygen
Explanation:
Frogs are able to breathe through their skin due to which its skin is thin and moist.
They can absorb oxygen from water even during hibernation period. The skin is extremely thin and is made up of thin membranous tissue which is permeable to the both water and air. The skin also comprises of blood vessels that allows diffusion of oxygen from water into the blood vessels.
Therefore, even if the lungs are poorly developed, frogs being amphibians can survive beneath the water. The presence of mucus glands make the skin looks wet all the time
Answer:
The correct answer is option B. "crude oil".
Explanation:
Crude oil was one of the first energy sources used for the production of electricity. Besides of its use as energy source, crude oil provides us with products such as ink, eyeglasses, and tires. Lower crude oil is used for some inks used for printing purposes; eyeglasses and sunglasses are considered petroleum based products for its need of crude oil; and crude oil is the primary raw material for the manufacturing of tires.
