The correct answer is "active transport is ATP dependent whereas in passive transport molecules use kinetic energy to move across the membrane." in active transport cells use molecules embedded on the cell membrane called carriers in the presence of energy. cells use energy and carriers because molecules must move against concentrated gradient inside the cell. on the hand, passive transport is a process by which molecules move from the region of high concentration to the region of low concentration across plasma membrane until balance is obtained on both sides of the membrane. once equilibrium has been achieved in passive transport the movement of molecules stops.
Answer:
Cellulose is a type of carbohydrate polymer is used for structural support in the cell wall within plants
Explanation:
Cellulose, for example, is a major component of plant cell walls, which are rigid structures that enclose the cells (and help make lettuce and other veggies crunchy). Wood and paper are mostly made of cellulose, and cellulose itself is made up of unbranched chains of glucose monomers linked by 1 4 glycosidic bonds

The answer is C, the galaxies are moving farther away.
Answer:
igneous rock
Explanation:
Look at the chart metamorphic rock melts turning into magma magma solidifies into IGNEOUS ROCK
Answer:
B
Explanation:
The lung not being not been able to exchange and remove the carbon dioxide created a health problem due to the concentration of hydrogen ions (H+) being 10X being higher than in normal body. Although the difference is just about 1, it will result increase hydrogen ion concentration 10 times, similarly an increase or decrease in pH from 4 to 2 will give rise to 100 times increase in hydrogen ion concentration. It can equally be applied to hydroxyl in concentration.
