Answer:
C) Na+ ions moving out of the cell
Explanation:
- Movement of Na+ ions out of the cell requires hydrolysis of ATP, a process called active transport.
- Active transport involves movement of materials against a concentration gradient using energy from the hydrolysis of ATP.
- Active transport system uses energy in the form of ATP to move substances such as ions into the cell or out of the cell.
Photosynthesis
Photosynthesis is the production of ATP through the conversion of energy from sunlight using chlorophyll.
Chlorophyl is found in plants, and plants use sunlight to make energy.
That energy is in the form of ATP.
When tiny ice crystals in clouds stick together to form snowflakes, the result is snow. If enough crystals form a clump, they'll become heavy enough to fall to the ground. When temperatures are cold and moisture in the form of tiny ice crystals exists in the atmosphere, snow forms.
Is silk softer than satin can be answered by science
Answer:
A. Crust
Explanation:
The most common chemical elements in the crust are oxygen (46.6%), silicon (27.7), aluminum (8.1), iron (5.0), calcium (3.6), potassium (2.8), sodium (2.6), and magnesium (2.1). These figures vary among different studies because we really have no way to know for sure.
