As in all animal cells<span>, the </span>cells<span> of the </span>human cheek<span> do not possess a </span>cell<span> wall. A </span>cell<span>membrane that is semi-permeable surrounds the cytoplasm. Unlike plant </span>cells<span>, the cytoplasm in an animal </span>cell is<span> denser, granular and occupies a larger space. The vacuole in an an animal </span>cell is<span> smaller in size, or absent.</span>
The active site’s primary function is to bind with the substrate molecule to undergo a chemical reaction.
Chloroplasts
Chloroplasts capture the energy in sunlight and use it to synthesize energy-rich carbohydrates. This food made by chloroplasts provides the chemical energy needed by all forms of life. Mitochondria help cells to extract the energy in food molecules efficiently to power cellular activities.
<span>B. Bending of light decreases
</span>According to the law of reflection, it stated that when light strikes
the boundary between different media, a portion of the light is reflected while
another portion enters the medium. Thus, the process in which the ray of light
crosses the boundary and enters the second medium is known as refraction.
However, the velocity of light decreases when light enters a denser medium.
The answer is going to be B
