Answer:
Chlorophyll is a green pigment found in chloroplast in plants. It absorbs sunlight during the process of photosynthesis. It is a chelate molecule. In a chelate molecule a central metal ion forms bonds with a large organic molecule made of carbon, hydrogen and other elements like nitrogen or oxygen.
In chlorophyll, magnesium is the central metal ion and it is bonded to a large organic molecule called as porphyrin. Porphyrin constitutes four nitrogen atoms to which the central magnesium is bonded in square planar arrangement. Since chlorophyll is responsible for the green color of the leaves, more the green color more the chlorophyll content and more is the nitrogen content. Hence, chlorophyll meter measures this green light and finds out if the plant needs more or less nitrogen.

Fibrous joints are connected by dense connective tissue consisting mainly of collagen. These joints are also called fixed or immovable joints because they do not move. Fibrous joints have no joint cavity and are connected via fibrous connective tissue. The skull bones are connected by fibrous joints called sutures.
Answer:
A. It contains fewer volatile gases.
Explanation:
Mafic lava have a composition of about 45-55% silica with high amount of Fe, Mg, Ca.
The silica content is quite low compared to those of granitic magma whose silica content can reach up to about 60%.
What determines the viscosity of magma is basically the silica content of the magma and the temperature of the magma. Viscosity is the resistance to flow.
The higher the silica content, the lower the viscosity and the higher the amount of volatile gases. Such type of magma is the granitic magma. Granitic magma due to their viscosity flows slowly.
The lower the silica content, the higher the viscosity and the lesser the presence of volatile gases in them. Such an example is Mafic magma. Mafic magma flows very slowly with low amount of dissolved gases.
Soaring is a science when birds remain airborne and moving without flapping their wings. They are maintaining thrust and gliding downward but staying aloft
<h3 /><h3>Further explanation</h3>
Soaring birds is where the birds can maintain flight without wing flapping, because they using rising air currents. Many gliding birds are able to lock their extended wings by means of a specialized tendon. Some land birds such as vultures and certain hawks, sustain flight for long periods without flapping their wings.
For example soaring California Condor spreads its primary feathers so that each acts as a small, high-aspect-ratio wing. This reduces turbulence at the wingtips and helping the condor to stay aloft circling slowly in thermals.
Vultures have a low aspect ratio (ratio of length to width of the wing) which generally produce a lot of drag. Vultures overcome the problem of by flying with their primary feathers extended, creating slots between them. Each primary serves as an individual high-aspect-ratio wing. This high-aspect-ratio reducing wingtip turbulence and lowering the stalling speed of the wings. This helps vultures to circle in thermals, maintaining thrust by gliding downward, but staying aloft by sinking at a rate slower than the hot air rising.
