Answer:
Matter cycles through an ecosystem through processes called biogeochemical cycles.
Explanation:
Photosynthesis
Plants build carbohydrates by taking in carbon dioxide from the atmosphere.
Carbon moves through the food chain
As organisms eat other organisms, carbon moves up the food chain. Molecules in the food that contain carbon transform into the organic molecules that make up the living body.
Carbon moves back to the environment
Organisms use food molecules, containing carbon, as a form of energy. The process of cellular respiration breaks down food molecules into carbon dioxide.
Contribution of industry
Humans contribute to moving carbon dioxide back into the atmosphere through the combustion of fossil fuels.
Use of fossil fuels
Today's fossil fuels were formed hundreds of millions of years ago by plants deposited in the Earth. The decomposition of the plants slowed down in such a way that their organic molecules are used for natural gas, coal and oil.
Diffusion into the air
From the oceans, carbon dioxide diffuses into the air. This creates a large amount of carbon, which is then taken in by plants to start the cycle over again.
<h2>Digestion of fats</h2>
Explanation:
Lipid molecules that are absorbed from the Gastrointestinal tract enter the lymphatic capillaries.
Lipids are digested in the small intestine after they are acted upon by the bile salts that emulsifies these large molecules of lipids.
Small droplets of lipids are then acted upon by lipase that breaks them into fatty acid and glycerol.
After this the enterocytes absorbs these digestion product and these flow into the lymphatic capillaries.
Answer:
Which of the following ventricles is found under the corpus callosum? lateral ventricles; the lateral ventricles lie side by side under the corpus callosum, separated by the septum pellucidum
Explanation:
Aerobic respiration is far more energy-efficient than anaerobic respiration. Aerobic processes produce up to 38 ATP per glucose. Anaerobic processes yield only 2 ATP per glucose.
Answer:
A) the lymphatic system only carries fluid away from tissues.
Explanation:
More differences between lymphatic system and circulatory system are:
• Circulatory system consists of a network of blood vessels through which blood is pumped by a “pump” called heart. In lymphatic system there is no such thing as a pump (only lymphatic vessels and lymph nodes)
• Lymph capillaries are closed on one side, so lymph does not circulate, but only drains to reach veins .
• Circulatory system has different role than lymphatic system: it tranports oxygen and other gases, nutrients and hormones, but also wastes that need to be excreted. On the other hand, lymphatic system has a role in immune system, fat and vitamin absorption and transportation.
