Answer:
The movement of glucose across the cell membrane through facilitated diffusion one of the form of passive transport because it does not require the energy to transport the glucose molecule across the cell membrane and the transport is along the concentration gradient.
In facilitated diffusion the passage of molecules if facilitated by a carrier protein or a channel protein. The rate of transport of molecules in facilitated diffusion is greater than simple diffusion.
Through facilitated diffusion, some polar and charged molecules can cross the cell membrane without the expense of energy.
Answer:
Conductors
Explanation: the substances which have a large number of free electrons and offer a low resistance are called conductors
Answer: the question is incomplete,below is the complete question.
List two species that may be threatened by the construction of a solar power tower in the California Desert
The answers are, Desert torties, mountain yellow legged frog and Joshua tree.
Construction of a solar power tower in the California Desert will threaten the existence of Desert torties, mountain yellow legged frog and and Joshua tree.
Explanation: The construction of solar power towers in Mojave desert in California poses a threat to the existence of quite a number of plants.The Mojave desert houses the largest solar power plant in the world,creating the solar power tower will create job opportunities for people but at the same time endangering the existence of about 12 rare plants that are found in the region of which Desert torties, mountain yellow legged frog and Joshua tree are greatly included,these plants cannot co-exist with solar thermal mirror arrays,this brings a controversy between energy/electricity generation and wildlife/ecosystem conservation.
