Answer:
The correct option is A. A semi-permeable membrane
Explanation:
A semi-permeable membrane can be described as a selective membrane that filters out which molecules to let-in and let-out of the cell. The semi-permeable membrane causes selective molecules or ions to move inside or outside it through processes like diffusion, facilitated diffusion, passive transport, active transport, osmosis etc.
On the other hand, a permeable membrane is not selective and will allow and will let any kind of molecules to pass.

Answer:
Water-wise cities -
Water management integrated into urban planning.
Full resources and energy used for wastewater treatment.
Local communities promote sustainable decision making.
Wasteful cities -
Local communities lack environmental awareness.
Almost all wastes dumped in landfills (This prevents wastes from getting recycled and also burdens the landfill's capacity.)
The Low percentage of stormwater separation
Explanation:
Water-wise cities are the cities that provide the proper management of the water including water treatment by utilizing full resources and energy. It helps in water management incorporated into urban planning. It is promoted by the local communities by sustainable decision making.
Wasteful cities are cities that have poor waste management. The local communities lack environmental awareness in such cities and dumped most of the wasted in open landfills and prevent recycling it and affect the ecosystem.
Answer with change in the environment organisms change to adapt to the change in of the enviroment .
Answer:
It allows rapid conduction of water from one vessel element to the next.
Explanation:
Vessels are one of the two types of conducting cells of xylem. Vessels are made of vessel elements. Vessel elements are the individual cells with perforation plates. The perforation plates have large holes (perforations). Perforation plates of adjacent vessel elements allow easier conduction of water from one vessel element to the next.
The perforated end walls of vessel elements allow these conducting cells to conduct water more readily than tracheids. Stacking of vessel elements with perforated end walls make the vessel like a water pipe through which water is being readily conducted.
