Hello!
This question requires a model -- you'll have to do that yourself. However, I can explain the steps for the process:
• Chlorophyll absorbs the sun's energy.
• The energy is used to split water molecules into hydrogen and oxygen.
• The oxygen is released from the leaves into the atmosphere.
• The hydrogen and carbon dioxide glucose (food) for plants.
If you have any more questions related to this assignment, please let me know!
Almost any and all so i say B. because A. C. and D. can all be used.
Answer:
hi!
Explanation:
The Mohs Hardness Scale ranks the order of hardness of minerals and some common objects. For example, your fingernail can scratch the minerals talc and gypsum, with a hardness of 2 or lower. A copper penny can scratch calcite, gypsum, and talc.
One of the most important tests for identifying mineral specimens is the Mohs Hardness Test.
This test compares the resistance of a mineral to being scratched by ten reference minerals known as the Mohs Hardness Scale (see table at left).
The test is useful because most specimens of a given mineral are very close to the same hardness. This makes hardness a reliable diagnostic property for most minerals.
"Hardness" is the resistance of a material to being scratched. The test is conducted by placing a sharp point of one specimen on an unmarked surface of another specimen and attempting to produce a scratch.
I believe your answer will be 40
