Paper chromatography is a technique used to separate molecules based upon their size and solubility in a particular solvent. If

pigments from a particular species of plant are extracted and subjected to paper chromatography, which of the following results is most likely?
a. Paper chromatography would separate the pigments into several bands that appear green or yellow/orange.
b. Paper chromatography would separate the pigments into two bands, one that appears blue and one that appears red.
c. Paper chromatography would produce a single band of pigment that is characteristic of that particular plant.
d. Paper chromatography would separate the pigments into two bands that appear green.

Answer:

a. Paper chromatography would separate the pigments into several bands that appear green or yellow/orange.

Explanation:

The primary or main pigment in plants is the chlorophyll. The chlorophyll gives plants their characteristics green colour and helps in the absorption of light during photosynthesis.

Other pigments in plants include carotenoid with its characteristic yellow, red or orange colour; anthocyanin with its re/blue colour and betalains with its red/yellow colour.

<em>Hence, if pigments from a particular species of plant are extracted and subjected to paper chromatography, one would expect the pigments to be separated into several colour bands ranging from green to yellow/orange.</em>

The correct option is a.

The smallest contractile unit within skeletal muscle would correspond to the distance between which two points in the figure?
Tpy6a [65]

The distance between 1 and 7 spans a sarcomere correspond the structure at B is covered by the perimysium.

<h3>What is the smallest contractile unit within skeletal muscle?</h3>

A sarcomere comprises the segment between two consecutive Z lines and is the contractile unit of the muscle fiber, as it is the smallest portion of the muscle fiber capable of contraction and distension.

In this case, the distance between points 1 and 7 has the smallest structure of a skeletal muscle and corresponds to figure B.

KonstantinChe [14]

Answer:

E = The activation energy barrier for this reaction can not easily be surmounted.

Explanation:

Starch:

Starch is a polymeric carbohydrate consist of various glucose units join together through glycosidic bonds.

Reason why it is not dissolve at room temperature:

When starch is added into water it form granules with cold water and can be soluble by heating.

At a room temperature the starch does not readily decompose to from the solution by decomposing into simple sugar because the activation energy barrier for this reaction can not easily be surmounted at a room temperature.
