The substance must be able to alter its physical characteristic (for example, its color) in accordance to a change in pH. One example of this is litmus paper, which becomes red under acidic conditions and blue under basic conditions.
Answer: d. High biodiversity in the understory.
Explanation:
The taiga or boreal forests are the largest biome in the world. These can be found in the regions of North America, Alaska, and United States. These regions exhibit extreme weather conditions. Typically long winters and moderate to high precipitation. The soil is permafrost and nutrient poor as no new organic matter can be added up to the soil due to it's freezing condition. The plant growth is scanty and biodiversity is low because organisms are incapable of surviving in the harsh weather conditions.
Fewer. more expose to sun could kill plants off.
Answer:
C
Explanation:
Im not 100% sure but I'm almost 100% sure thats the answer
Answer: This is What drives ocean currents
- Surface is primarily driven by wind (friction from wind transfers energy and momentum to surface water)
- Deep is slower, driven primarily by density (salinity and temperature) differences
- Thermocline: dramatic temp drop 50 m from surface bc sun can't shine
- Halocline: dramatic gradient in saline, increase as it deepens
- Pycnocline: resulting change in density (50-1000)
