Pure breeding means the same as selective breeding since you take two animals and combine their traits for certain reasons
The correct answer is '<span>Oxygen is used up as algae is decomposed, reducing the amount available to other organisms.</span>' The additional nutrients in the water will result in an algal bloom. These algae will result in drastic oxygen fluctuation, from oxygen rich conditions during the day as algae photosynthesize, to anoxic conditions during the night when the algae respire. However, the algal bloom will eventually deplete the available nutrients, resulting in a vast algal die off. The decomposing algae result in anoxic conditions, and the effects are sometimes very obvious, with fish gasping for breath and dying.
global warming is a increase in earths overall temperture caused increased levels of carbon dioxide, chlorofluorocarbons, and other pollutants.
to prevent global warming we could:
Drive less, Recycle more, Use less hot water, Plant a tree, Turn off electronic devices when not being used such as a T.V
all of these ideas save pounds of carbon dixoide and if you look above it is listed as a cause of global warming
The answer is; the skeletal system and the nervous system
The skeletal system (muscle and bone) give you rigidity and enable your legs to support your weight. The muscles also act on the bone as a fulcrum allowing it possible for them to contract and make motion possible.
The nervous system is important in the coordination of movement. The brain is the center for locomotor action. This ensures you are able to place one foot in front of the other in sequence and moving your arm in concert.
I agree because an ecosystem and a host are basically the same thing.
