The genotype is the genetic makeup of an organism.
Explanation:
It is the set of genes that the organism inherited from its parents and is expressed through its phenotype, or physical properties.
Answer:
They know that layering, or bedding, is the most obvious feature of sedimentary rocks. This Law of Superposition is fundamental to the interpretation of Earth history, because at any one location it indicates the relative ages of rock layers and the fossils in them. Layered rocks form when particles settle from water or air. That is kinda easy :D
Explanation:
A cell would have 46 chromosomes during metaphase I.
Rainwater picks up carbon dioxide from the air and as it percolates through the soil, which turns into a weak acid. This slowly dissolves out the limestone along the joints, bedding planes and fractures, some of which become enlarged enough to form caves.
