Answer: Punnett Square
-----
A punnett square is used to display the possible outcomes of a genetic cross. The parents' alleles are written across the top and the side, and the possible genotypes are written in the boxes (see image).
 
        
             
        
        
        
Answer:
"Be freezing at night because the planet has no atmosphere" is the correct answer.
Explanation:
I was doing my reading in OW and I quote this is what OW said:
Temperatures during the day can reach 430°C (800°F), but can drop to -170°C (-280°F) at night because there is no atmosphere to trap heat.
Hope I helped:)
Have a great day!!!

<h2>Membrane potential </h2>
Explanation:
- Membrane potential represents charge difference across the membrane, all biological cells are negative inside (cytoplasm) and positive outside (due to difference in ionic distribution)  
- In a typical neuron cell membrane potential of cytoplasm is negative at rest (when no stimulus is applied) hence called resting membrane potential 
- Resting membrane potential of excitable cells is established by Na+ and K+pump 
- Repolarization starts with the efflux of K+ by the opening of voltage gated K+ channels 
- Voltage gated K+ channels starts to open when voltage gated Na+ channels becomes inactive 
- Hyperpolarization occurs due to excessive efflux of K+ by voltage gated K+ channels
- Additional efflux of K+ occurs due to slow inactivation of voltage gated K+ channels
