<h2>Answer:</h2>
Option B is correct.
B. In an exothermic reaction, excess energy is released as heat.
<h2>Explanation:</h2>
An exothermic reaction is a chemical reaction that releases energy by light or heat. It is the opposite of an endothermic reaction. Expressed in a chemical equation: reactants → products + energy. Exothermic Reaction means "exo" meaning releases and "thermic" means heat.
There are many forms of electromagnetic energy<span> including gamma rays, x rays, ultraviolet </span>radiation<span>, visible light, infrared </span>radiation<span>, microwaves and radio waves. </span>
With the sequence of the gene-coding regions of the human genome in hand and the development of newer sequencing methods, scientists are able to
1. develop new forensic tests that can help in the identification of the convict.
2. diagnose genetic diseases before their onset.
3. develop customised medicines based on the genetic profile of the patient.
4. therapeutically target the cancer causing genes (oncogenes) in the patients.
5. understand the inheritance of genes especially the rare mutations in a population.

Answer:
Energy enters the biosphere as sunlight.Plants change this energy into chemical energy through the process of photosynthesis. Then, the energy is passed to organisms that eat the plants. Energy and matter is also passed between organisms when they eat one another.
