Answer:
The inward flow of sodium ions increases the concentration of positively charged cations in the cell and causes depolarization, where the potential of the cell is higher than the cell's resting potential. The sodium channels close at the peak of the action potential, while potassium continues to leave the cell.

Answer:
All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing. When viewed together, these characteristics serve to define life.

Answer:
11. b.
Explanation:
Photosynthesis stores energy in carbohydrates, cellular respiration releases energy from carbohydrates.
Glucose, C₆H₁₂O₆, is a carbohydrate.
Write out the equations:
<u>Photosynthesis</u>
carbon dioxide + water + light energy => oxygen + glucose/sugar
CO₂ + H₂O + light => O₂ + C₆H₁₂O₆
The carbohydrate is stored in the plant until it needs it, like to perform cellular respiration.
<u>Cellular Respiration</u>
oxygen + glucose/sugar => carbon dioxide + water + ATP energy
O₂ + C₆H₁₂O₆ => CO₂ + H₂O + ATP
The carbohydrate is used to make energy. Energy is released from carbohydrates.
Glucose, C₆H₁₂O₆, is a carbohydrate.
Fault in other options:
a. Photosynthesis and cellular respiration both occur in plants. Plants have mitochondria for cellular respiration.
c. Photosynthesis uses carbon dioxide and cellular respiration releases carbon dioxide.
d. Photosynthesis uses carbon dioxide, cellular respiration uses oxygen.
Answer:
The water property being shown is surface tension
Explanation:
Due to the surface tension, small objects will "float" on the surface of a fluid, as long as the object cannot break through and separate the top layer of water molecules. When an object is on the surface of the fluid, the surface under tension will behave like an elastic membrane.
