Photosynthesis - The cycle of plants and how they make energy! The sun(light energy), water, minerals and carbon dioxide are all absorbed by the plant. The plant then uses them to make glucose/sugar, which is the energy/food for the plant.
After a caterpillar eats a leaf, it can convert the chemical energy into mechanical energy to help it build a cocoon.
Boundary between two air masses of different temperatures and/or humidity levels
Answer:
During summer in the northern hemisphere, the days are longer than winter.
Explanation:
Earth tilting is the main cause of formation of seasons. Summer season occurs when the earth tilt towards the sun. The earth tilt about 23.5 degrees toward the Sun. Summer occurs when the northern hemisphere tilt toward the Sun because sun rays directly hit that area which increases the temperature of that area and those areas experience winter which do not recieves direct radiation of sun.
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.
