Answer:
Phenotypic plasticity
Explanation:
Humans have evolved over thousands of years to adapt to various environmental changes. For example, when we are in an environment that requires certain level of adaptation our off spring often formalizes epigenetic traits that lows them to overcome small changes in the environment. Over time certain genes that are turned on may remain on and eventually the ones that are off remains off. This give rise to some genes that "don't work" after millions of years of such evolution we end up with a complex genome with more DNA than "working genes".
The answer B. Chromosomes
One of the components of the auditory system is the malleus incus and stapes that make up the auditory ossicles. Osteogenesis Imperfacta is a genetic disorder that affects the proper formation of connective tissue in the body.
Bones, on the one hand, are constituted by connective tissue. The disorder will consequently affect the formation and integrity of the auditory ossicles, therefore, leading to hearing loss.
I think the mean DNA but don't quote me on that.
Answer:
Been brought about by the cell theory announced by Theodor Schwann and Matthias Schleiden in 1838, whereby cells were held to be the basic units of all living tissues. Improvements in the microscope during the 19th century made it possible gradually to lay bare the basic structures of cells.
