Explanation:
Stem cells begin to transform into different types of cells in the human body in a process known as cell differentiation.
Cellular differentiation occurs throughout the cell development of a multi-cellular organism. It occurs when the cell changes from a simply zygote into a complex system of tissues and cell types.
Stems cells are cells which have the potential to develop into many different cell types in the body during early life and growth. Stem cells serve as internal repair system in many tissues. When stem cells divide while undergoing cell differentiation, it can either retain being a stem cell or become another type of cell like muscle cell, brain cell, or red blood cell.
Answer:
Louis Pasteur demonstrated that cells can only arise from pre-existing cells.
Explanation:
The contributions of Louis Pasteur are one of the most remarkable in the history of humanity. Before Pasteur performed the experiments that revolutionized the cell theory, most people believed in the theory of <u>Spontaneous Generation</u>, which <u>stated living organisms could arise from non-living matter.</u>
However, in the 18th century, <u>Pasteur performed a series of experiments that disproved the theory of Spontaneous Generation</u>. By using using covered and non-covered flasks with broth, he demonstrated that cells were only able to grow in the broth if it was not properly covered, that is, if the air was exposed. This illustrated that cells couldn't arise from non-living matter but the opposite: cells can only arise from pre-existing cells. This was an extremely significant contribution to the cell theory.
Ear canal
Sound waves enter the outer ear and travel through a narrow passageway called the ear canal, which leads to the eardrum. The eardrum vibrates from the incoming sound waves and sends these vibrations to three tiny bones in the middle ear.
