Explanation:
Alkaloids are essentially natural compounds, and can mostly be used for pharmaceutical purposes. Natural habitats of different alkaloid plants have been destroyed for cultivated.
Many alkaloids are pharmacologically active and are useful as a message for several decades because a wide range of species, such as animals and bacteria, produce them.
Secondary and accumulating metabolites are related to different cell types such as epidermis endodermis pericycle phloem parenchyma, components, accompanying cells etc.

The correct alignment for a solar eclipse is <span>sun - moon - Earth. It is letter A.
>Solar Eclipse--only occurs when </span><span>Moon passes between Earth and Sun
>Its shadow has</span> two parts namely:
<span>1. Penumbra--<span>The Moon's faint outer shadow.
</span>2. Umbra---<span>The Moon's dark inner shadow.</span></span>
The atomic number of an isotope is the number of protons it contains, whereas the mass number is the total mass of the nucleus, which is the combined number of protons and neutrons in the nucleus. To find the number of neutrons, you must therefore subtract the atomic number of the isotope from the mass number of the isotope.
<span>In the above example, the atomic number is 8 and the mass number is 18. This isotope is known as O18. The number of neutrons in the isotope is: Mass number - Atomic number = Number of neutrons
