A. destruction of stratospheric ozone. Due to the inventions that helps people to have transportation but along these inventions it produces vast amount of smoke that destroys the ozone.
Answer:
NPS pollution generally results from land runoff, precipitation, atmospheric deposition, drainage, seepage or hydrologic modification. As the runoff moves, it picks up and carries away natural and human-made pollutants, finally depositing them into lakes, rivers, wetlands, coastal waters and ground waters.
Explanation:
FASCILITATED DIFFUSION
Facilitated diffusion, also called carrier-mediated osmosis, is the movement of molecules across the cell membrane via special transport proteins that are embedded within the cellular membrane. Large, insoluble molecules, such as glucose, vesicles and proteins require a carrier molecule to move through the plasma membrane.[1]<span> Therefore, it will bind with its specific carrier proteins, and the complex will then be bonded to a receptor site and moved through the cellular membrane. Facilitated diffusion is a passive process: The solutes move down the concentration gradient and don't use extra cellular energy to move.</span>
Answer:
Generally in non flowering plant the male sex organ is called the antheridium,while the female is called the achegonium. Due to the habitat and methods of reproduction, special adaptive feature s have been developed by these plants to ensure reproduction and prevent extinction.
Explanation:
Based on structure,Antheridial (male sex cells) are usually upright in position,with pores located at the top of the antherialdial disk.These perforation is adaptive feature for effective dispersal of sperm during reproduction.
In addition present in the archegoniu is the achegonium dsik. The latter is the adaptive feature for protection of the archegonia.The disc serve as an umbrella surface for the protection of the archegonia during reproduction.Thus ovum is well protected to ensure fertilization and prevent wastage.
