Enzymes are made of strings of amino acids chemically bonded to one another. These bonds give each enzyme a unique structure, which determines its function. They mostly break down carbohydrates and fats. Once a protein source reaches your stomach, hydrochloric acid and enzymes called proteases break it down into smaller chains of amino acids. Amino acids are joined together by peptides, which are broken by proteases.
Answer:
c. Directional selection
Explanation:
Directional selection is a type of natural selection that occurs when selective pressure favors one extreme phenotype over any other phenotype existing in a population. Only one extreme phenotype is favored over time.
A good example of directional selection is the natural selection that occurs in giraffes, where alleles for long necks were favored against alleles for short necks as a result of selection pressure among the different phenotypes. Over time, giraffes having long necks dominated the population as the distribution of length of neck shifts towards the phenotype for long necks.
Answer:
The correct answer is - bottom-up processing.
Explanation:
In sensation and the perception process, there are two general processes - Bottom-up processing and top-down processing. Bottom-up processing is the processing that involves the processing of the sensory information is coming in such as the eyes detect any picture, brain collect all the information all together and you perceive a whole picture.
All the information is processed on the base of the sensory information that comes. Bottom-up is basically collecting information and forming it all together.
Thus, the correct answer is - bottom-up processing.
