a. Both EPSPs occurring in rapid succession
b. The summed EPSPs depolarizing the axon hillock membrane to —70 mV
c. Both EPSPs occurring before the postsynaptic membrane potential returns to —55 mV

Answer:

Both potentials occurring after the postsynaptic membrane potential returns to its resting value

Explanation:

This is simply because, a neuron returning to its resting state,will have the ligand gated Na+ channels closed.Therefore depolarization can not occur.More K+ gated channels will open, and more K+ leaks out of the axoplasm,returning the neuron to the resting state.

Hence if  the summation of the two EPSP returns to the resting level after crossing the synapse, they can not propagate,and generate action potential, because they will produce  a sub threshold effects,which  will not generate action potential.

how do the strategically placed covalent and hydrogen bonds present in dna facilitate the functioning of the molecule
Sergio [31]
<h3><u>Answer and explanation;</u></h3>
  • DNA is a double stranded molecule. Covalent and hydrogen bonds pray important roles in the functioning of DNA molecules.
  • <em><u>Covalent bonds occur within each linear strand and strongly bond the nucleotide bases, sugars, and phosphate groups occurring both within each component and between components.</u></em>
  • <em><u> Hydrogen bonds occur between the two strands and involve a base from one strand with a base from the second in complementary pairing.</u></em>
  • Hydrogen bonds helps the complementary base pairs in DNA; guanine with cytosine and adenine with thymine to connect to one another. The hydrogen bonds between these complementary pairs helps keep the two strands of DNA helix together.

What are some water pollution management strategies, what do you think is the best one and why?
lesantik [10]

Answer:

There are plenty of things that we as individuals can do to slow down the amount of pollution going into the ocean, these could include not flushing anything down the toilet that won't disintegrate (because no matter where you live, all toilet pipes lead to the ocean), converting plastic use to reusable materials; this could include using reusable straws, water bottles, shopping bags, etc. and of course, when you need to throw plastic out, always recycle. :)  

Explanation:

I believe the best way an individual can help the oceans is by converting plastics to reusable or at least eco-friendly products. If everyone made a conscious effort to do this, the oceans would be MUCH clearer.

Hope this helps!
