The correct answer is D.
Cellular respiration is the process by which glucose molecules are broken down in the presence of oxygen to produce energy in form of ATP, water and carbon dioxide are also given off as the by products of the reaction. Thus, for cellular respiration to occur, the raw materials that are needed are glucose and oxygen while the products of the reaction that are formed are energy, water and carbon dioxide. Living organisms used the energy produced to carry out life sustaining activities of the cells.
The largest organ in an earthworm is its skin
The independent variable is the plant growth or how much the plants grow.
Answer:
active transport
Explanation:
Active transport is the energy-requiring process of pumping molecules and ions across membranes "uphill" against a gradient. The active transport of small molecules orions across a cell membrane is generally carried out by transport proteins that are found in the membrane.
Lunar phases are basically the different positions of the moon that we see throughout its whole cycle, from new moon to full moon, back to new moon. Eclipses, though are more rare phenomena. These occur when the sun, moon, and earth line up at a specific position.
Asteroids are usually dense bodies, with many different formations on their surface. They are also believed to be the largest source of precious metals on our planet.
Comets are bright clouds of gas surrounding a center nucleus that speed toward the sun and heat up at the same time. They contain dust, ice, carbon dioxide, and other gases. As the comet soars toward the sun, the radiation pushes dust particles back, forming the tail they are known for.
