Which of the following statements about biofuels is true? a. biofuels are composed of 100% renewable materials. b. algae is the leading source of biofuels. c. energy processing from corn biofuels is not energy efficient. d. corn is the only source of biofuels. select the best answer from the choices provided a b c d

A . Biofuels are composed of 100% renewable material.

Explanation:

Biofuels are majorly of plant origin. Manufacturers tend to covert crop and its products to ethanol for biofuel utilization. Corn is not the only source of biofuel, sugarcane and a lot of other plants are used as well.

Energy processing from corn is very efficient owing to its high starch content. Biofuels are the future of mankind as they are renewable.

Biofuels are composed of 100% renewable materials. (Ans. A)

Explanation:

Biofuels are known as fuels which is produce by biomass from animal waste or plant material. Mainly it is generated by plants which has been harvested. It is also known as renewable source of energy. 3 main types of biofuels are:

1) Ethanol: Which is used by most cars in engines which helping to burn gasoline.

2) Biodiesel: Which is used by trucks in engines which are burning diesel fuel.

3) Biojet: This fuels are used by planes.

Biofuel is renewable because it can be produce by the things which can grow again and again such as trees. Biofuel is also defined as the fuel which is produce from living things and their waste.

in the year 2850, humans successfully colonized mars. the martian modules that were constructed could hold only a small population of people. it is now a century later, and the population on mars has grown to 600 people. of the current mars population, 45 people express the recessive phenotype for phenylketon- uria (pku) syndrome (pp genotype).

explanation:

not necessarily. higher fitness requires the organism to be reproductive successful. for example, an organism at age 10 with 15 offspring is much more fit than an organism at age 15 with only 5 offspring.
