Answer:
B. SONAR (Sound Navigation Ranging)
Explanation:
Just took the test
Answer:
Primary producers
Explanation:
Phytoplankton belong to the <u><em>primary producers</em></u> trophic level. Beings of the other levels gain energy from phytoplankton. Phytoplankton are also capable of transforming inorganic carbon into protoplasm.
Exothermic gives off heat/energy and endothermic takes in heat/energy. Exothermic example: a candle flame
Endothermic example: baking bread
In Exothermic, you can expect the surrounding temp. to rise, and in Endothermic you can expect the surrounding temperature to fall.
Hope this helps
Hello!
You would expect to observe
2 triplets in the ¹H NMR spectra for o-chlorotoluene.
Multiplicity observed in ¹H NMR spectra when the atom couples with a neighbor ¹H atom. The multiplicity is equal to
N+1 where N is the number of neighbor atoms.
To observe a triplet, you'll need a molecule with 2 neighbor atoms. In o-chlorotoluene (shown in the figure), only protons C and D have 2 neighbor atoms (B and D; A and C, respectively), so you'll expect to see a 2 triplets.
Have a nice day!
