Answer:
Diffusion, osmosis and active transport are three similar chemical methods by which single molecules or very small structures are moved across membranes or relatively short distances, often within or between cells.
Explanation:
The movement of substances in and out of cells is a very important part of biology as without it no cell and so no organism could live very long. Substances can only cross the protective cell membrane by diffusion, osmosis or active transport. Mass flow only works at the organ, tissue and whole organism level.
Answer:
Carbon
Explanation:
Most organic compounds contain carbon, hydrogen, and sometimes other elements such as nitrogen, sulfur, oxygen, or phosphorus. All living organisms contain carbon—even bacteria.
It is to help transport macromolecules back and forth between the nucleus and the cytoplasm. the nuclear pore complex also serves as a barrier between the cytoplasm and nucleus to prevent harm to genetic material housed in the nucleus :)
Sensory neurons and motor neurons are only two of the basic types of neurons. The basic function of neurons are in transmitting nerve impulses to the different parts of our body. Sensory neurons<span> carry signals from peripheral parts of our body into the central nervous system. On the other hand, m</span>otor neurons<span> carry impulses from the central nervous system to the peripheral parts of our body.
Best answer: </span><span>sensory neurons carry stimuli information to the brain; motor neurons carry processed information to muscles and glands. </span>
