There are many more examples of chemical digestion which takes place in the body. Chemical digestion is the breaking of larger more complex molecules into smaller, simpler ones that can be taken up by the cells more easily and readily by the use of chemical agents.. Chemical digestion is carried out primarily using biological molecules called enzymes. For example, the breakdown of starch is done by an enzyme known as amylase, which is present in the saliva.
So what roles do society, politics, and economics play in science?Economics determines how much money is available to fund scientific research. Certain federal grants come directly out of the national economy, which determines if certain research projects can continue or are cut off.Politics affect science by passing some bills that directly affects science, congressmen can determine whether those funds from the economy will be used for research or not. Just a side note: wealthy lobbyists control alot of what politicians do, by donating millions into their election campaigns. Society affects science by our citizens democratically electing those politicians that we think will or will not endorse scientific research projects. For example, embryonic stem cell research has been under fire by conservatives for taking future babies' cells to study. Liberals, however, tend to be in favor of change and new advances scientifically

if you need it shorter "Society, made up of the country's citizens, can influence science by electing politicians (president and congressmen); the politicians can then affect the economic funding of scientific research, either by increasing or decreasing government grants to scientific projects."
Chemoreceptor is a specialized sensory receptor cell, which responds to a chemical substance and generates a biological signal.
The type of chemoreceptor responsible for our sense of smell is called olfactory receptor. It is also known as odorant receptor, these are found in a small patch of tissue high inside the nose. These cells directly connected to the brain.
They both need nutrients to carry out life functions
