Answer:
1. Source of carbon
2. Removal of cuticle
Explanation:
You may have been doing a photosynthesis lab in a biology course.
1. NaHCO₃
The purpose of creating a sodium bicarbonate solution was to provide the carbon that the plant needs for photosynthesis.
2. Soap solution
The soap solution acted as a detergent. It removed some of the waxy, water-repelling cuticle from the leaf's surface and made it easier for the sodium carbonate solution to get inside.
Answer:
126000J
Explanation:
From the question given, we obtained the following information:
M = 1500g
C = 4.2J/g°C
ΔT = 20°C
Q =?
Q= MCΔT
Q = 1500 x 4.2 x 20 =
Q = 126000J
1. c
2. It resembles the crystalline structure of ice
3. It should be eco-friendly
4. Similar- still falls in rain or snow when the cloud is full enough
Different- adding chemicals to quicken the process, not waiting for it to happen naturally
5. Droughts- plants dying, no crops- no food
