Answer:
C) polysaccharide: glycosidic bond
Explanation:
Monosaccharides are the simplest carbohydrate which cannot be further hydrolysed. Examples of monosaccharides are glucose, fructose. Monosaccharides combined together to form polysaccharides. Polysaccharides are long chains of monosaccharides linked by glycosidic bonds. The glycosidic bond is a covalent bond. It is formed between an anomeric carbon of one cyclic monosaccharide with the alcoholic or OH group of a second monosaccharide. Examples of polysaccharides are starch, glycogen and cellulose.

Answer:
The two strands are held together by hydrogen bonds between the bases, with adenine forming a base pair with thymine, and cytosine forming a base pair with guanine.
Explanation:
Answer:
migration, which is a response to an external stimulus
Explanation:
<u>The butterflies were migrating in response to external stimuli.</u>
Migration is the movement of organisms from one place to another in response to external stimuli. The stimuli could be for food, shelter, weather, etc.
<em>Flight in response to external stimuli is often due to the presence of danger as stimuli. The adrenal gland releases epinephrine which triggers physiological changes in the body and makes the organism decide whether to run, stay, or fight. </em>
In this case, the butterfly could have been migrating in response to the availability of flower nectars or pollen which serve as food for them. Once flowers are available during the spring, the butterflies come around and when the winter comes and the flowers disappear, they migrate away.
