The right option is; Segregation
The diagram represents the Mendel’s law of segregation.
The law of segregation is one of the principles of heredity discovered by Gregor Mendel. Mendel's law of segregation states that all organisms possess two pairs of alleles for each trait and that these alleles seperate during meiosis in a such a way that each gamete have only one pair of the alleles. The law explains that when an organism produces gametes, one gene copy is distributed to each of the gametes and that the selection of the gene copies is random.
I believe the answer is B.
<span>In the process of photosynthesis, carbon dioxide is taken from the atmosphere and oxygen is realased. But now with the evolution, the atmosphere has much more oxygen than carbon dioxide. So the first step of absorbing carbon dioxide itself has been challenged by the process of photosynthesis.</span>
Answer: Option D) Pupil
Explanation:
Pupil is the hole in the middle of the iris of the eye, through which light passes to be focused on the retina. Thus, the pupil is analogous to the hole in the centre of a doughnut
Ozone is good when it is in the stratosphere but bad when in the troposphere (where the weather system occurs). When in the stratosphere it help absorbs UV light from sunlight before reaching earth surface. This prevents damage to the genetic material of living organisms.
When in the troposphere, it is considered a pollutant and causes irritation of the lungs when inhaled. It also affects vegetation by reducing crop growth and yield.
