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.
Your body can store some fuels in a form that offers muscles in a immediate source of energy. Carbohydrates such as sugar are readily broken down in glucose, the part of your bodies principal energy source.
Hoped this helpes! =)
Answer:
light reaction and dark reaction.
Answer:
<em>The correct options are D. dark-colored, small-sized snails and F. dark-colored, large-sized snails</em>
Explanation:
Evolutionary studies show that those organisms are able to survive and reproduce which are better adapted to live in an environment. Gradually, the organisms that are better adapted to live in an environment increase in number and those that are not better adapted will decrease in population.
As Avian snail kites feed on light- colored apple snails and Avian limpkins feed on medium- sized apple snails, this means that these species are not better as they can be easily captured by their predators.
The dark colored, small- sized snails and dark- colored, large- sized snails will be better adapted to live in the environment as they will not attract the predators. Hence, they will survive and reproduce.
