Epigenesis
Epigenesis is the concept that emphasizes development resulting from ongoing bidirectional exchanges between heredity and all levels of the environment.
Epigenesis is the development of organisms such as plants, animals and fungi from an egg, seed, or spore or egg through a series of phases in which unorganized cells differentiate into organs and organs systems. The theory of epigenesis which claimed that structures evolve during development that are not already preformed was created by the German physician C. F. Wolff in 1759.
Answer:
allopolyploidy
Explanation:
Polyploidy is the condition by which a cell might have more than two chromosome sets that form homologous pairs. It might occur due to a failure or abnormality in cell division.
Autopolyploidy
Refer to a type of polyploidy in which an organism has more than two copies of homologous chromosomes. It results from the duplication of a group of chromosomes of the same species. Autopolyploid individuals have <u>at least three groups of homologous chromosomes</u>. Autopolyploidy is produced by the<u> gamete fusion of the same progenitor - same species</u>-, duplicating the number of chromosomes of diploid species. The autopolyploid cell has groups of homologous chromosomes. Autopolyploidy is produced mainly due to non-disjunction during meiosis.
Allopolyploidy
Refer to another type of polyploidy in which species have more than three sets of chromosomes in their cells. Allopolyploidy <u>occurs when two different species mate</u>, leading to the fusion of gametes that belong to different species and produce a new hybrid. The chromosomic complement has more than two copies of chromosomes. The hybrid is infertile with the parental species. The allopolyploid cells have chromosome groups that are not homologous.
In the exposed example two different species mate and produce a hybrid species.
Answer:
Production of proteins
Explanation:
Ribosomes consist of RNA's and special proteins that help to synthesize other proteins. Ribosomes can be found either floating within the cytoplasm or attached to the endoplasmic reticulum. They
Weak acids such as carbonic or sulfuric acid react with rocks in the ground, such as limestone. Groundwater reacts with limestone and the dissolving of limestone takes place which forms karst features, such as caverns.
