Answer:
A
Explanation:
There is no much more to say than the letter A describes the process of facilitated diffusion.
The normal diffusion ocurres when the solute passes the membrane through the space of the double layer of phospholipids. Particles that are small and apolar can pass trough the membrane without problems.
For bigger or polar particles we need to use a protein system to help them pass into the cytoplasm. That's what we call Facilitated Difusion.
About the other options:
B) That's the explanation about active transport. That happen for every particle who is going against the gradient of concentration.
C) Again: if we are talking about diffusion, there is no energy needed.
D) The Water Molecules suffer the process os osmotic pressure. Water deslocates to the higher gradient of concentration - contraty what the other particles do.
Answer:
Cycle: A repeated pattern, The sun: The orgin for the water cycle, The water cycle: The process by which water circulates between the oceans, atmosphere, and land, Evaporation: The sun heats up water and turns it into vapor, Condensation: Water vapor in the air that gets cold and turns into water, Percipitation: water that falls in the form of snow, rain or hail.
Answer:
Fossil fuels, including coal, oil and natural gas, are currently the world's primary energy source. Formed from organic material over the course of millions of years, fossil fuels have fueled U.S. and global economic development over the past century. Yet fossil fuels are finite resources and they can also irreparably harm the environment. According to the U.S. Energy Information Administration, the burning of fossil fuels was responsible for 76 percent of U.S. greenhouse gas emissions in 2016. These gases contribute to the greenhouse effect and could lead to potentially catastrophic changes in the Earth’s climate. Technologies such as Carbon Capture and Storage (CCS) may help reduce the greenhouse gas emissions generated by fossil fuels, and nuclear energy can be a zero-carbon alternative for electricity generation. But other, more sustainable and less risky solutions exist: energy efficiency and renewable energy.
It has a type of function
Answer:
Plants take in Carbon Dioxide and filter it releasing oxygen.
