Answer:
Use of recycled products and renewable energy.
Explanation:
Use of recycled products and use of renewable energy are the solutions which provide resources to everyone and no damage cause to the ecological systems of the environment. By using recycled products have two advantages i. e. the product's price decreases and no pollution occurs while the use of renewable energy such as use of solar radiation for the production of electricity. With this energy, no pollution occurs in the environment and electricity can be provided to a lot of people with low cost.

Answer:
D
Explanation:
Facilitated diffusion is a form of passive transport hence no energy is required by the cell. This means that while the molecules are moving down a concentration gradient – line normal diffusion – the movement of the molecules needs to be facilitated (in this case by a transmembrane protein) either because the molecule is polar and can't pass through the hydrophobic region of the cell membrane, or the molecule is too big to passively pass through the small natural pores of the cell membrane.
Answer:Light Absorption by PSI Excites Electrons and Facilitates Electron Transfer to an Electron Acceptor Outside the Thylakoid Membrane. PSI is another large protein-pigment complex that contains lightabsorbing antenna molecules and a reaction center.
