The baby is not getting a balanced diet to meet its bodily needs, and that's why the baby is at high risk of the mentioned above. If a child is undernourished, especially below 2 years of age, it may result in permanent problems with physical and mental development, and since early childhood is an important period for cognitive, behavioral, and physical development, a nutritious diet is the most important factors for ensuring a child reaches optimal development.</span>
The features or characteristics of organic compounds include:
1. They contain covalent bonds and are mostly non polar in nature
2. Have lower boiling and melting points than inorganic compounds
3. Many organic compounds are thermally unstable, They decompose into simpler molecules when heated at fairly high temperatures
4. Most organic compounds are inflammable and burn exothermically in sufficient air to yield carbon dioxide, water and heat energy.
5. Most organic compounds being largely non polar are insoluble in water.
A model organism is a species that has been widely studied to understand a particular biological phenomena, normally used because they are easy to breed and maintain in a laboratory setting and has certain experimental advantage.
The criteria that Thomas hunt Morgan was looking for include; the model organism should be small in size, easy to keep in the laboratory and also able to produce large number of off springs in a short time.
