Answer:
b) and c)
Explanation:
Greenhouse gases are gases found in the atmosphere that absorb infrared radiation and trap the sun’s heat, thereby producing an effect known as <em>greenhouse effect.</em> By this natural way, the earth is able to be kept warm at an optimal temperature, to make it habitable for humans and other organisms. These gases referred to as <em>greenhouse gases</em> include, carbon dioxide, methane, water vapour and other trace gases found in the atmosphere. Greenhouse gases could be likened to the glass in a greenhouse that helps in trapping heat to keep the greenhouse warm at optimal temperature necessary for plant growth and development.
Without this natural greenhouse effect caused by greenhouse gases, life on earth would be almost impossible as the earth would almost be covered with ice below 0 degrees Fahrenheit.
The increased level of greenhouse gases we now find in the earth’s atmosphere is responsible for the additional warming of the earth’s surface, causing an enhanced greenhouse effect which results in global warming.
Statement a) cannot be used as an explanation because it is false. Greenhouse effect makes the earth habitable.
Statement d) cannot be used as an explanation because carbon dioxide is not the only greenhouse gas that matters. Water vapour, CFC and methane also have impacts.
<em>Statement b) and c) are the best statements to use in explaining the true nature of greenhouse effect.

<u>ANSWER:</u>
"Reduced concentration of substrate" available can interfere with the "ability of an enzyme" to catalyse a reaction. The main use of enzymes is to increase "the rate of reactions".
<u>EXPLANATION:</u>
- There are several factors that have an impact on the ability of an enzyme to catalyse a reaction.
- These include temperature, pH levels, and the quantity of substrate as well as the reactant. When the "substrate concentration increases", the rate of the reaction also increases in the presence of an enzyme.
- On the other hand, when the "substrate concentration is low", the enzyme cannot catalyse the reaction at a fast rate.
Answer: Gathered food was stored
Explanation: An important characteristic of the earliest permanent human settlements was that gathered food was stored. This allowed the settlements to survive better through harsh times, such as the winter. Also, by storing food less, hunters were needed for the settlement, and individuals began to focus and learn other trades to advance with civilization.
