Answer:
The plants excrete more 'carbon dioxide' in the night because photosynthesis does not take place during the night. Explanation: The plants give our oxygen and take in carbon dioxide because they can prepare food by the process of 'photosynthesis' by using 'carbon dioxide and water'.

Answer:
Advantages of using ethanol as fuel
A. It is a carbon-neutral activity
C. It does not produce toxic gases when burnt
D. It can be mixed with conventional petrol to make gasohol
Disadvantages
B. It takes a lot of plant materials to produce the ethanol
Explanation:
It has been proven that blending ethanol with conventional petrol produces gasohol and this helps to reduce the harmful emissions of CO, hydrocarbons, etc. This then means that vehicles that run on ethanol produces fewer harmful emissions than those that run on gasoline. For ethanol, it produces a no net carbon dioxide emissions.
Ethanol is considered to be atmospheric carbon neutral when the combustion of ethanol is made from biomass (such as sugarcane and corn). Ethanol is made plant materials like grains and crops that possess high starch. Also, it can be made from sugar content such as sugar cane, sorghum, corn, barley and sugar beets.

Answer:
Population distribution is the spreading of people over an area of land, while population density is the number of people per unit land.
Explanation:
The distribution of population is how people are distributed over an area of land and the population density indicates how densely populated an area is and it is often determined by the number of people per square mile.
Answer:
The three hormones are insulin, glucagon, and GIP and GLP-1.
Explanation:
After the ingestion of carbohydrates, insulin increases in the blood generating peaks in blood glucose, therefore the hormone that will increase is insulin to lower blood glucose, promoting the entry of this monosaccharide into the cells.
Different from the moments when the person enters into physical activity, and blood glucose is low, therefore glucagon is activated and seeks to remove the energy reserves from the interior of the cell.
