Answer: B. sugar; respiration
Explanation: To obtain energy needed for life processes and activities, respiration must occur. Respiration involves the break down of glucose (A disaccharide sugar) to produce energy in form of ATP.
The equation for respiration is C6H12O6 + 6O2 --> 6CO2 + 6H2O + Energy.
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.
Answer:
c. Both are used to determine the age of objects.
<span>Cells in a meristem differ from cells in other types of plant tissue differ in that they continue to divide. They are embryonic tissue that never differentiated or matured, and they give the plant the ability to grow. They are true stem cells in that they continue to divide via mitosis, and a portion of them remain undeveloped throughout the life of the plant. They are totipotent by logic, which means that any adult plant cell can be derived from them. It is this quality that allows a plant to grow new leaves if some are torn off and that scientists strive to unravel.</span>
