D. The heat is there via convection from the sun
Explanation:
The valence electrons determine the group the elements belong in the periodic table. For example, the element sodium, Na, has a valence electron of one and so it belongs to Group 1 in the periodic table. Another example is Aluminium, Al, which has a valence electron of three and therefore it belongs to Group 3 in the periodic table.

Answer:
Intially the glucose concentration is levelled and then the liquid level in side A will rise.
Explanation:
- Initially the liquid ob both sides are in isotonic condition.
- The membrane is permeable to glucose so glucose will diffuse from higher concentration (2 M) to lower concentration (1 M) until the concentration become equal (1.5 M) on both sides.
- Know, the Side A have 2 M sucrose and 1.5 M glucose and side B have 1 M glucose and 1 M sucrose.
- The side A will become hypertonic and side B will become hypotonic and water will start moving from side B to side A.
