Endotherms need to consume more food to keep their metabolism up and maintain consistent temperatures (homeotherapy). This is because they are a warm-blooded organism which is dependent on the internal generation of heat.
Answer:
- production of vaccine for disease prevention
- production of genetically modified crops
Explanation:
Recombinant DNA is a special type of DNA that has been infused with a foreign gene of particular interest.
With recombinant DNA technology, scientists can study different proteins and see how they can be used for therapy in the area of medicine. <em>The technology has been used to produce several vaccine in the prevention of diseases.</em>
In addition, recombinant DNA technology has been useful in agriculture to produce <em>genetically modified crops with desired traits such as resistance to pests/diseases and high yields.</em>
The three changes of state during which energy is absorbed are:
1. Change from solid to liquid - Melting.
2. Change from liquid to gas - Vaporization
3. Change from solid to gas - Sublimation
All these changes of state require heat energy to break the attractive forces that hold the particles of the molecules together, so that they can move into more disorderly states. For instance, when heat is applied to a solid, the solid absorbs the heat and use it to break the attractive forces that are holding the molecules of the solid together. At a particular temperature, the attractive forces will be completely overcome and the solid framework will collapse, thus leading to the melting of the solid.
Answer:
Today, drug-resistant infections are a serious threat to people's health. Hundreds of thousands of lives are lost every year because of infections that can no longer be treated with existing drugs. Discovering new antibiotics, able to kill drug-resistant bacteria, is essential to saving modern medicine.
