Answer:
The correct answer is - B. they build up soil deposits on the rocky ground.
Explanation:
Lichens and mosses are known as the pioneer species as they prepare the particular region for the next stages of succession on the bare volcanic region. Lichens and mosses grow on the bare rocks and secrete acids to break the rocks and start soil production.
The soil deposits produced by breaking the volcanic rocks by secreting acids from mosses and lichens. Even after dying these species leads to thickening of the soil and increase organic matter for the next stages to grow.

Answer:
The correct answer will be-
1. Law of inheritance
2. Law of Independent Assortment
3. Meiosis
Explanation:
Gregor Mendel is known for his work on the pea plants to study the pattern of inheritance of traits in a population.
On the basis of his work, Laws of inheritance were proposed in which the main three laws were the Law of dominance, Laws of segregation and law of independent assortment.
The Law of inheritance suggested that factor (genes) responsible for a trait come in pairs and is inherited one from each parent to the offspring.
The law of Independent Assortment stated that these genes segregate and passed on to the offspring independent of each other.
The cell division associated with the formation of a germ cell is known as meiosis which produced four daughter cells with different genetic material.
