There is no genetic diversity in cloning, so this makes cloned dogs more vulnerable to viruses, higher risks to newly evolved diseases. Breeding brings new variations into the existing gene pool if you cross breed. Also, different parents can result in different and potentially better combinations of genes, so breeding is better.

Breeding might not give the desired results while cloning might have ethical issues. Breeding might bring an improvement of the species.

Pros:
– End starvation immediately
– The GMO food might have more nutrients
– The GMO food might have higher resistance to pests, poor growing conditions, thus leading to better food output and security.

Cons:
– Indebted to other countries
– GMO crops might contaminate wild origin crops
– People might develops allergies to the GMO crops

a) C6(H2O)6

c) No. As they have different structures, it leads to different physical properties and therefore different tastes.

Everything is made out of chemicals, even all organic food consists entirely of chemicals. It is impossible to go on an “all organic chemical-free” diet because food itself is made up of chemicals. The highly advertised organic diet might not always be better because of the misconceptions that inorganic chemicals is bad and natural organic chemicals is better, this is not always true. It is also very hard to go on an organic diet because the method and the process by which the food is grown must be very strictly adhere to organic certifications, which means it will be highly costly.

a) Exothermic: Heat is released during exothermic reactions
b) Endothermic: Heat is absorbed during reaction. Water absorbs heat from the surrounding and from our body temperature which translate into energy for the conversion of liquid to gaseous state.
c) Endothermic: Heat is absorbed during reaction. Ice absorbs heat from surroundings which results in the energy provided for solid to become to liquid.

A good explosion would be more exothermic. For exothermic reactions, the products have a lower energy level than the reactants, therefore bond strength of products is less than bond strength of reactants.

Heat is a form of energy transfer while temperature is the measurement of the amount of heat. Temperature is the direction of the flow of heat. For example, you feel hot because of the heat from the sun, and you can check the temperature with a thermometer.

a) 98% isooctane and 2% heptane
b) Octane rating does not indicate the level of oxygenates in fuel. Oxygenates are usually in gasoline to reduce carbon monoxide.
