Something about the Artic Biome And desert biome
Answer:
needs more info to be answered could you state them down or put a pic
Explanation:
My answer may not be precise, but I believe if you changed your question to "The presence of these structures indicates that the student is looking at a cell of what organism", then I would safely say a plant, because plants, unlike animals, have cell walls in addition to cell membranes. :) Hope this helps!
Answer: 77.0J
Explanation:
The magnetic field is given as 4.40T
Since the volume is not given, we assume that the volume is 10.0cm³
We need to find the magnetic field energy in this volume.
The energy density is:
u = B²/2u•
u• is given as 4π × 10^-7 T.m/A
Using this formula we substitute
u = B²/2u• = (4.40 T)²/ 2(4π × 10^-7 T.m/A) = 7.704 × 10^6 J/m³
The energy is equal to the energy density multiply by the volume. You get;
U= uV = (7.704 × 10^6 J/m³) × (10.0 × 10^6m³) = 77.0J
Answer: B. The crops and livestock are bigger and stronger, so they provide more food per square foot of land.
Explanation: Good luck! :D
