This is an example of; evolution
Evolution is a gradual process in which the characteristics of a species are changed in response to its environment over several generations. Evolution depends on the process of natural selection. Some of the changed characteristics (traits) may be beneficial to the organism and it can be transferred to their offspring.
the specimen ... is what’s it’s called
The answer to this question would be: smell
The sensory organ that catch smell is located in the nose and will send the signal into the olfactory bulb. The olfactory bulb is located in the bottom part of the brain, near the hippocampus(which was the center of memory), and amygdala (which was the center of emotion).
Shortly after gastrulation, the body and organs of the embryo begin to form. This process is called <u>embryogenesis.</u>
<u></u>
- The process by which an embryo transforms into a fetus is known as embryogenesis.
- The three germ layers that eventually give rise to the various organs in the animal body are formed as a result of gastrulation.
- Embryogenesis is the name of this process. As a result of differentiation, organs emerge from the germ layers.
- The process of creating and growing an embryo from a zygote (zygotic embryogenesis) or a somatic cell is known as embryogenesis (somatic embryogenesis).
- An incredibly well-organized series of cell division, expansion, and differentiation takes place during embryo development.

The best answer is B - Proteins.
Proteins make up enzymes, or to put it another way enzymes are made up of protein. It is enzymes that speed up the chemical reactions. Enzymes are organic catalysts, substances that speed up a (biochemical) reaction but do not take part in the reaction and remain unchanged at the end of the reaction.
In man, there are many enzymes. The majority of these are found in the digestive system where they greatly aid the process of food breakdown from complex molecules to simple molecules. Examples include salivary amylase found in saliva, which begins the gradual breaking down of starch into glucose right from the moment food is placed in the mouth and mixed with saliva. Pepsin in the stomach breaks down protein.
