Question 1 (Multiple Choice Worth 3 points)
abruzzese [7]

Answer:

As of plants, bioluminescent algae fix carbon dioxide in the presence of sunlight and release oxygen. Further, during this process, they produce light as a part of photosynthesis products. Therefore, the use of bioluminescent algae can reduce anthropogenic carbon dioxide from the environment.

Bioluminescent algae-based lamps are being prepared by scientists to overcome these environmental concerns. Furthermore, these lamps would be used as street lights and reduce energy demands as well (burning of fossil fuels).

Which of the following statements about resting potential is true? A resting membrane allows much more sodium than potassium to
AleksAgata [21]

Answer:

The sodium-potassium pump contributes to the resting membrane potential.

Explanation:

This is the stage in which the neuron is not depolarize. 3Na+ are pumped outside  through  the sodium  channels, while  K+ channels are open for2 K+ to enter the cells.After some time the Na+ channels closed up. However some K+ channels still leaks , so that K+ still escape out of the cells to the external environment ,which contains more of Na+. Therefore at this stage there are more Na+ outside the neuron compare to the inside the neuron. Therefore the inside of the neuron is negative , because more K+ are leaving the cells, leaving negatively charged anions inside, and the outside is positive  due to more Na+ are outside, and because the K+ leaking outwards.

The regulation of the Na+ and K+ ions movements is regulated by sodium potassium pumps along the membrane of the neuron. if the potential at this stage is measured, it has a value of -70mv, and it is called membrane potential.
