1.

Not diversifying the genes
Results in inheritance of all weaker genes
Cross-breeding may eliminate weaker genes and inherit the stronger genes from either parent.

2.

PROS
Higher crop yield but could be restricted cause of drought and lack of water
Reduce the need for pesticides

CONS
Possible new diseases
Other organisms in the ecosystem could be harmed.

1.

The production of extra H2O will be of concern as it begs the fundamental question of ‘where will the produced water go?’. If the water is released to the external environment its effects would be dependent on temperature. For example, in freezing temperatures the water released onto roads would freeze causing hazardous driving conditions. If the excess water is kept within, it means that extra mass must now be stored-creating problems with space and for vehicle’s energy efficiency. Water is also a greenhouse gas, therefore, is dangerous to the environment is excess amounts.
Negative Consequences: Expensive, storage, replacing current infrastructure, flammable.

2.

Fossil fuels are hydrocarbons, coal, oil or natural gas formed from the remains of dead plants and animals. Fossil fuels is a general term for buried combustible geological deposits of organic matter and materials. They are formed from decayed plants and animals by exposure to heat and pressure in the Earth’s crust over hundreds of millions of years.

3.

The electrolysis of water to produce hydrogen gas requires energy, and hence there would be an accompanying need to burn fossil fuels to generate the enormous amount of heat required to split water through electrolysis. Therefore, cost and pollution would be high.

a. C6(H2O)6
b. Drawing
c. Isomers differ in their physical property. Since taste is a physical property. The sweetness differs.

2.

All organic molecules consists of atoms. For instances, glucose.
Glucose is made up of carbon, hydrogen, and oxygen atoms held together with covalent bonds. Therefore, organic compounds are made of chemical compounds.
