Answer:
The following are the factors, which should be taken into account while evaluating a biofuel include:
a. Net energy balance
b. Should not compete with the production of food

d. Energy balance ratio
e. Should be neutral or carbon negative
The first generation biofuel is generated from sugarcane, which produces ethanol, and this eventually results in the elevation of grain prices. There was a controversy regarding the generation of raw material for its application as food or fuel.

The correct statement about the hemoglobin and myoglobin is as follows:
1. Each hemoglobin molecule can bind four oxygen molecules; each myoglobin can bind only one oxygen molecule.

4. Both hemoglobin and myoglobin contain a prosthetic group called heme, which contains a central iron atom.
5. Heme is composed of an organic protoporphyrin component and a metal atom.
6. Each iron atom can form six coordination bonds: One of these bonds is formed between iron and oxygen.
