I think it's the first answer
Gregor Mendel, through his work on pea plants, discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent. Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits. He recognized the mathematical patterns of inheritance from one generation to the next. Mendel's Laws of Heredity are usually stated as:
1) The Law of Segregation: Each inherited trait is defined by a gene pair. Parental genes are randomly separated to the sex cells so that sex cells contain only one gene of the pair. Offspring therefore inherit one genetic allele from each parent when sex cells unite in fertilization.
2) The Law of Independent Assortment: Genes for different traits are sorted separately from one another so that the inheritance of one trait is not dependent on the inheritance of another.
3) The Law of Dominance: An organism with alternate forms of a gene will express the form that is dominant.

atmospheric air, through the nose it goes to the trachea and then via bronchus and bronchioles, it ultimately goes to the alveolus where the exchange of different gas takes place.</span>
Answer:
Water molecules infiltrate in the soil through small pores made by soil fauna. If soil has high porosity, the water infiltrate quickly into the soil or if the soil has low porosity, so the movement of water is difficult in the soil.
Explanation:
Porosity refers to the comparison of total volume of rock in total volume of soil. If there more empty space in the soil we can say that the soil has high porosity.
