Answer:
Diffusion is the movement of particles from an area of high concentration to an area of low concentration.
Osmosis is the movement of particles from an area of high concentration to an area of low concentration in a liquid through a semi-permeable membrane.
They are similar because they are both the movement of particles from an area of high concentration to an area of low concentration.
They are contrasting because osmosis includes a liquid and a semi-permeable membrane.
Answer:Ultraviolet radiation. Invisible rays that are part of the energy that comes from the sun, can burn the skin, and cause skin cancer. UV radiation is made up of three types of rays -- ultraviolet A (UVA), ultraviolet B (UVB), and ultraviolet C (UVC).
Explanation:Ultraviolet (UV) is a form of electromagnetic radiation with wavelength from 10 nm (with a corresponding frequency around 30 PHz) to 400 nm (750 THz), shorter than that of visible light, but longer than X-rays.
How are we to know the answers without knowing about which groups the question pertains.
Cell differentiation is a process by which stem cells give rise to different type of cells with different functions and located in different locations. it is is true that all cells in a particular organism have same composition of genetic material. however they perform different function because of the process of cell differentiation. cell differentiation results from expression of some genes inside the cell the dictate what type of cells should be synthesized.after gene expression proteins produced send the message to stem cells to indicate the type of cells to be manufactured.
Answer:
The natural resource distribution depends on many physical factors such as land, atmosphere, and altitude. Asset distribution is unequal because these factors differ on this planet from place to place.
