The digestive system use the cardiovascular system for the transport of materials
Answer:
Both osmosis and diffusion are examples of passive transportation wherein energy does not need to be exerted to produce an effect. Both are also a means to make the concentration of two solutions equal. Here, we will discuss how osmosis and diffusion differ from each other.
Osmosis - is the process where liquid moves from a higher region of concentration to a lower region of concentration through a semipermeable membrane. Usually, the solvent or liquid involved in this process is water. Osmosis is an essential process that helps animals transport nutrients and maintain water on a cellular level, as well as help plants absorb water from the soil.
Diffusion - is the movement of particles from a higher region to a lower region of concentration. These particles can be solid, liquid, or gas. Unlike osmosis, particles do not move through a semipermeable membrane. It is a faster process than osmosis, which is quite slow. Diffusion is important because it allows processes like exchange of gases when animals respire or assists in transpiration and photosynthesis for plants.
The likely causes of the abnormal protein could be, both choice 1 and choice 2. Both are pretty similar in their consequence, since they describe a mutation which either keeps RNA polymerase to keep going after it usually stops or the stop codon, is not a stop site anymore. This causes are well documented and some of them are causes of illness. The third option, although feasible, it would find many obstacles, since introns would be hard to traduce. So, to sump up, choice 1 and choice 2 are the correct options.
