Answer:
Streak Test
Explanation:
A streak test is used by geologists to help determine the powdered color of a mineral. They usually use a white or black plate, scrape a sample of the mineral onto the plate, and voila!
P.S. I also had a question like this on a test before.
Answer:
"without light energy from the sun, photosynthesis would still occur" is completely false. Light energy is needed for the light-dependent reactions, or simply the light reactions, of photosynthesis.
"oxygen is an input into photosynthesis, carbon dioxide is an output" is also completely false. It is the opposite.
These statements are true, however:
SUNLIGHT
CARBON DIOXIDE
WATER
MINERALS
OXYGEN
PLANT SUGARS
Carbon dioxide enters the leaves through stomata (tiny holes) in the leaves.
Sunlight is an input, CO2 is an input, water is an input (taken in through the roots, transported through the veins), minerals are a collective input, oxygen is an output (produced during photolysis), and plant sugars are an output (glucose, for an example).
Answer: Ectotherms depend on external heat sources. Their body temperature changes with the temperature of the environment. Endotherms generated heat internally to maintain body temperature.
Explanation:
Answer: CO2 impacts the atmosphere because it causes temperatures to slowly rise over time. Oxygen produced from plants counter act CO2 with the carbon dioxide exchange but it still impacts the atmosphere to a certain level. it affects oceanic areas because it causes sea levels to rise, as well as increase the acidic levels in the water. hope this helps!
