Which of the following is a NOT mechanism by which the biofuels are made? a. by reacting animal fat or vegetable oil with waterb. by fermenting sugar components of starchy cropsc. by reacting animal fat or vegetable oil with alcohold. by treating animal fat or vegetable oil with hydrogen

A. by reacting animal fat or vegetable oil with water.

D. by treating animal fat or vegetable oil with hydrogen

Explanation:

Water is insoluble in animal fat or vegetable oil so it makes a layer on the surface of oil. When animal fat or vegetable oil react with hydrogen, it produces solid oil called ghee not biofuels. Biofuel is produced when animal fat or vegetable oil react with alcohol.

Option A and D.

Explanation:

Biofuel is fuel that produced from either plants, algae or animals. There are four main types;

Ethanol that is made from corn.

Biodiesel made from animal fats and vegetable oil.

Green diesel made from algae and plant sources.

Biogas e.g methane made from animal manure and digested organic material.

Ethanol a type of biodiesel is made from fermentation of sugar components in starch crops.

Biodiesel is made from reaction between animals fats or vegetable oil with alcohol.

a. seed plant structure. 1. the three main plant organs are roots, stems, and leaves. a fourth kind of tissue, meristematic tissue, is responsible for plant growth. meristematic tissue is the only plant tissue that produces new cells by mitosis. plants can lose water out of their leaves as they exchange gases with the air

explanation:

a) carbon, hydrogen

b) carbon, hydrogen, oxygen, nitrogen

c) carbon, hydrogen, oxygen, nitrogen, phosphorus

d) sugar

e) amino acid

f) nucleotide
