Answer:
In the respiratory system, you inhale oxygen which is transferred to the blood in the alveoli and circulated throughout the body. The blood in the circulatory system has a protein called hemoglobin which binds to the oxygen and carries it throughout the body. This oxygen is then given to the different cells for cellular respiration. It then carries the waste products (CO2) of cellular respiration back to the lungs and it is exhaled out.
Answer:
carbon dioxide
Explanation:
we inhale oxygen and exhale the carbon dioxide
Answer: It absorbs light.
Explanation: Chlorophyll is a pigment inside of all trees and plants. Plants absorb light, if the chlorophyll is green, then it will change the plant, and make it look green. It can change depending on the day, and temperature. If it is fall, the leaves cannot eat, and change to red. If the temperature is normal, say 90 degrees, the leaves are healthy, and eat. This helps them stay green.
<span> I think Sea otters are an iconic species, representing the beauty and diversity of marine life found along California’s coastline. They’re also considered a keystone species because of their critical importance to the health and stability of the nearshore marine ecosystem. They eat sea urchins and other invertebrates that graze on giant kelp. Without sea otters, these grazing animals can destroy kelp forests and consequently the wide diversity of animals that depend upon kelp habitat for survival. Additionally, kelp forests protect coastlines from storm surge and absorb vast amounts of harmful carbon dioxide from the atmosphere. Sea otters are also considered a sentinel species because their health reflects that of California’s coastal waters.</span>
