Aquatic life transitioned to terrestrial life when anatomy structures began to change in ways such as fins slowly evolved into legs, gills into lungs, and instead of suction feeding they started to bite instead.
Answer:
<em>The tactic which will be of no help will be A) Increase your demand for green products and services to reduce your carbon footprint.</em>
Explanation:
Increasing demand for green products will require the cutting down of trees for meeting up the needs. Hence, lesser the trees, more will be the carbon dioxide as trees tend to take up carbon dioxide and use it in the process of photosynthesis.
Also, by using green products, our carbon footprint will not be reduced because the amount of carbon dioxide we release will remain the same. Hence, option A is the correct option.
Answer:
Anemia is a condition in which the blood has a lower amount of red blood cells or hemoglobin than in a healthy individual. As a result, enough oxygen is not transported to the cells and tissues where they are needed.
Explanation:
The red blood cells found in blood function to transport oxygen from the lungs to the cells and tissues where they are needed. The molecule that helps the red blood cells to perform this function is called hemoglobin. Iron is required by the body to make hemoglobin. Hemoglobin is an iron-rich protein that gives the red color to blood due to the heme molecule in hemoglobin. each hemoglobin molecule is able to bind four oxygen molecules.on inspiration, air fills the lungs and diffuses through the alveoli sacs into the capillaries carrying oxy-deficient blood from the lungs. The oxygen molecules diffuse into the red blood cells and are bound to hemoglobin in the red blood cells. From the lungs, the red blood cells transport the oxygen and deliver it to the cells and tissues.
However, in an individual with anemia, transport of oxygen to the tissues is impaired and the individual develops symptoms such as fatigue, dizziness, and shortness of breath, etc. Eating foods rich in iron can help to improve the individual's condition.
