Answer:
diffusion through a selectively permeable membrane
Explanation:
The cell membrane selectively allows certain substances to enter or leave a cell . This implies that cell membranes are selectively permeable; they allow some substances to pass through, but not others.
Direct transport of materials across the cell membrane is often passive. Passive transport does not require energy to occur. Passive transport is the movement of substances from a region of higher concentration to a region of lower concentration. A concentration gradient is always required.
The diffusion through a selectively permeable membrane is an example of passive transport.
The iodine moves into the dialysis tube across the semi permeable cell membrane from a region of higher concentration to a region of lower concentration in response to a concentration gradient.
Answer:
DNA is nucleic acid

Answer:
There is an increase in demand for higher quality and quantity of food and other products.
Explanation:
There is an increase in demand for higher quality and quantity of food and other products. So, there is a huge requirement for technological innovation. Investment is needed in research and development to develop crops that are pesticide-free, resistant to disease, and able to face various weather conditions. Vertical farming and carbon-capture technology can be used to meet growing world food demands.
I don't understand ur question. Hmm
Explanation:
Each section of the electromagnetic (EM) spectrum has characteristic energy levels, wavelengths, and frequencies associated with its photons. Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies. Radio waves, on the other hand, have the lowest energies, longest wavelengths, and lowest frequencies of any type of EM radiation. In order from highest to lowest energy, the sections of the EM spectrum are named: gamma rays, X-rays, ultraviolet radiation, visible light, infrared radiation, and radio waves. Microwaves (like the ones used in microwave ovens) are a subsection of the radio wave segment of the EM spectrum.
