Answer:
Option (C)
Explanation:
When many trees are removed from any area, the area becomes dry and gets adversely affected. Due to the lesser amount of trees, the area will evaporate more due to its dry and increasing temperature, as a result of which there will be more precipitation. This precipitation will lead to more amount of surface runoff over the area. So the transpiration will simultaneously decrease as the plants will not be able to absorb water by its roots, that regulates the overall temperature of the plant and protects it from dying.
Thus, the transpiration process is directly proportional to the number of plants and trees in any area.
Thus, the correct answer is option (C).

Explanation:
Haemoglobin is a complex protein consists of heme and globin. Heme contains iron as central element.
The prosthetic group of hemoglobin and myoglobin is heme.
The organic ring component of heme is porphyrin.
Under normal conditions, the central atom of heme is Fe²⁺.
In deoxyhemoglobin the central iron atom is displaced 0.4 A out of the plane of the porphyrin ring system.
The central iron atom has 6 bonds: 4 to nitrogen atoms in the porphyrin, one to a histidine residue and one to oxygen

Answer: Light goes into the eye via the cornea, it then pass through the pupil, the lens, the vitreous humor and finally forms an image on the retina.
Explanation:
Light goes into the eye via the cornea. The cornea is a clear, dome-shaped surface that covers the front of the eye.
From the cornea, the light passes through the pupil. The pupil regulates the amount of light passing through.
From the pupil, , light hits the lens. The lens is the clear structure inside the eye. It focuses light rays onto the retina.
Subsequently, light passes through the vitreous humor. A clear, jelly-like substance that fills the center of the eye. It helps to keep the eye round in shape.
Finally, the light reaches the retina where the image is formed the image is usually inverted. The retina is a light-sensitive nerve layer that is situated at the back of the eye.
The main function of the optic nerve is to carry the signals to the visual cortex of the brain. The visual cortex turns the signals into images.
