Answer: Small intestines
Explanation: Digestion of carbohydrates begins in the mouth mechanically and through salivary amylase. It passes down to the stomach by parastalsis, digested further and goes to the small intestines where their absorption begins. Carbohydrates are a source of glucose, that most organs use as their primary energy source. Indigestible carbohydrates and fibers travels down to the large intestines where they are digested by bacteria or eliminated as waste through the anus.
The small intestines consist of microvilli that increase surface area for maximum nutrient absorption. Carbohydrates are absorbed by the small intestines via the jejunum, taken to the blood stream then transported to the liver where glycolysis and most metabolic pathways take place, for energy production.
B. 2.883 million kilometer
Answer:
Explanation:
This is because ferns are vascular plants i.e they have vascular tissues which are xylem and phloems which help to conduct water and nutrients while mosses are non vascular plants.
2. Ferns sporophytes are differentiated into true leaves, stems and true roots while mosses lack true roots, stems and leaves.
Underground stems are modified part of plants that are derived from stem tissues which grow under the ground. Underground stems grow beneath the soil. Examples include Rhizomes, ginger, tubers e t.c.
Answer:
See the explanation below, please.
Explanation:
The amino acid sequence of a protein will determine the interactions inside and with the environment (that is, it will influence the conformations that are adopted at physiological temperature: the degrees of freedom). Example: the proline amino acid (Pro) has a cyclic structure, which implies a limitation in the random movement of the polypeptide chain.
In proteins, the primary structure determines the sequence of the amino acid sequence of the polypeptide chain (amount of amino acids present and their order by means of peptide bonds).
