Answer:
The correct answer is : A. a ratio of 1 carbon atom to 2 hydrogen atoms to 1 oxygen atom
Explanation:
Carbohydrates are the primary and major component of diet, these molecules give vitality to the body, predominantly by means of glucose, a fundamental sugar, which is an part of the starch and a fixing in different staple nourishment diet choices.
the significant chemical formula of carbohydrates is (CH2O)n. It can be exhibited or express by the proportion of the carbon to hydrogen to oxygen which is 1: 2: 1 in the particles of starches. Starches are additionally arranged into three sub-sorts, that is, monosaccharides, disaccharides, and polysaccharides. The monosaccharides are the basic sugars, for instance, glucose.
Thus, the correct answer is : A. a ratio of 1 carbon atom to 2 hydrogen atoms to 1 oxygen atom
Answer:
retrograde axoplasmic transport
Explanation:
The retrograde axoplasmic transport is a type of fast axonal transport that moves the substances at a fast rate by using proteins. These proteins transport the substances along the surfaces of the microtubules of the cytoskeleton of nerve cells. The retrograde axoplasmic transport moves the substances towards the soma or cell body from the terminal ends of the axon. This type of axonal transport mostly moves the substances that are to be recycled or broken down.
