Active transport requires energy because unlike osmosis and diffusion which are passive transport methods which sees where the particles are moving along the concentration gradient, in active transport, the particles are moving against the concentration gradient and as such energy through ATP is needed for the particles to be transported.
Climate change
Greenhouse effect
Some heat energy from the Earth’s surface escapes into space. If too much heat energy escaped, the planet would be very cold. However some gases in the atmosphere can trap escaping heat energy, causing some of it to pass back to the surface.
These are called greenhouse gases, and they keep our planet warm, which is a good thing. Carbon dioxide is an important greenhouse gas.
Increasing carbon dioxide levels
Humans burn fossil fuels such as oil, coal and natural gas. The energy released is used to power cars and other machines, to generate electricity, and to keep buildings warm. The burning fuel releases waste gases, including carbon dioxide. As the human population increases, more fuel is used, and more carbon dioxide is released.
Global warming
The extra carbon dioxide increases the greenhouse effect. More heat is trapped by the atmosphere, causing the planet to become warmer than it would be naturally. The increase in global temperature this causes is called global warming.
I think it’s 75% I’m so sorry if it’s wrong
Answer:
Air Pressure
Explanation:
Air pressure is the only option here related to weight. And Air Pressure does get lower the higher the airplane goes.
B.
I'm pretty sure because, chemicals and pesticides can easily make insects more immune. So therefore the average pesticides will no longer work on them but also some may not be affected by the solutions.
