Endothermic reaction
An endothermic reaction is those reactions that take up energy from the environment as that proceeds. The opposite is an exothermic reaction that gives off energy to the environment.
Explanation:
When cooking an egg you require energy to break down the interactions between the protein chains and atoms of the raw egg so they are rearranged into a cooked egg. This is akin to the denaturing of proteins. Cooking food helps ease their digestion. Because we need energy to break down the interactions and bonds of the proteins in the egg this is why we use fire in cooking. This is, therefore, an endothermic reaction.

1. It increases carbon dioxide in the atmosphere.
Plants and trees play a vital role in keeping the planet habitable. As most of us probably know, photosynthesis (a process that happens in plants) filters carbon dioxide gases out of the air and releases oxygen. This means that cutting huge numbers of plants can have a very negative impact on the environment. It will allow green house gases to build up and contributing to global warming.
2. It further promotes the development of drought.
Global warming brings about a lot of unfavorable consequences, including drought, which is already affecting many parts of the world. To mention, deforestation encourages higher levels of water consumption for growing livestock and crops. Instead of having a natural system of moisture recycling forests provide, water goes to food and livestock production, removing it from the natural cycle of life.
3. It focuses only on short-term gains.
According to research, the world is already producing more than 10% of the calories it needs for the entire world population today. In fact, many countries are consuming more than 1,000 calories a day per capita, which is more than the needed amount for proper health. We should take note that, if more food is produced, then people will tend to focus more on short-term gains, instead of meeting long-term needs.
4. It is a limited resource.
Regardless of the many monetary benefits we can get from deforestation at first, these timber profits could go away since there will not be any additional trees being planted to replace those that are harvested. Livestock and farms may not be nearly as profitable as a living, considering the thriving forests on a planetary scale.
5. It contributes to the extinction of wildlife.
The removal of a habitat is often the foundation for the extinction of a species. When forests are cut down, it is not only the trees that are being lost, but also countless amounts of wildlife, such as mammals, birds, insects, amphibians and many other animals that make them their home. With nowhere else for them to go, they will be forced into areas that are not suited for them. In fact, there has been a drastic decline in the amount of wildlife in certain areas that have experienced severe effects of deforestation. In essence, we are removing a piece of ourselves when we no longer allow for animals to exist as they always have.

Answer:
Proteins.
Explanation:
Protein is one of the major biomolecule of living organisms and acts as a main building block of the body. Proteins are the polymers of amino acids.
Most of the enzymes present in living organism are made upof proteins. Antibodies made up of heavy and light chains are the constituent of proteins. Hormones like insulin, glucagon and epinephrine are proteinaceous in nature. Muscle contains protein like actin, myosin and nebulin. Hence, protein can act as antibody, enzyme, muscle and hormone.
Thus, the correct answer is option 2.
A layer of permafrost prevents the decay of organic material that enriches the soil.
B.
Too much water promotes chemical weathering and washes away nutrients.
C.
There is enough water to promote chemical weathering, but not enough to wash away nutrients.
D.
There is not enough rainfall to promote chemical weathering or retaining nutrients.
