Answer:
Nicholas Steno
Explanation:
Nicholas Steno who was a Catholic priest establish relationship between sedimentary rock layers otherwise called stratigraphy.
Stratigraphy is a branch of geology that deals with the study of rock layers. He established theoretical law of stratigraphy by introducing law of superimposition, principle of original horizontality and the principle of lateral continuity in 1669 work of fossilization of organic matter sediments.
Answer:
When starfish were removed from their environment, the species richness of that area went down. This was because the starfish ate the mussels, and when the starfish were removed, the mussels became abundant and preyed on many of the other species.
This experiment showed that the starfish were a keystone species. A keystone species is a species that has a low biomass but a large impact on the community they are living in.

<h2>Answer 1 with Explanation</h2>
Homozygous dominant- It can be an organism if it carries two copies of the same dominant allele as homozygous which clearly means that the organism has a pair of models that is the corresponding allele for a gene. This gene originally belongs to a particular gene that has same alleles on both homologous chromosomes. It is assigned to by capital (XX) in the subjective terminology.
<h2>Answer 2 with Explanation</h2>
Heterozygous dominant is an organism that carries two different alleles of a gene. Though this is originally is referred to as (Tt). Heterozygous means that an organism has two different varieties of the gene within the system of dominant, the protein each makes is slightly different from one another and the organism has both tall and short versions within the dominant.
<h2>Answer 3 with Explanation</h2>
Homozygous recessive is described as an organism that carries two copies of the same recessive allele in the living organisms while they are in process of growth. A recessive gene is one that has to be homozygous to have an effect on the plant's or animal's traits that is naturally in process. This process of homozygous is is referred to by the lower case (xx).
