The motor cortex in the fontal lobe is responsible for your ability to place your foot on the brake pedal and stop at a red light.
The frontal lobe are the largest lobe in the cerebrum region of the brain, it also important for the voluntary movement, expressive language and for managing higher level executive functions. It also help to maintain balance and posture of the body.
The frontal lobe is present in the right behind our forehead. The skull protects the cerebrum part of the brain. When the frontal lobe damage then the speech and language get affected, the memory disorder, attention, judgement, movement, and behavioral disability.

When looking at phylogenetic trees such as this you should always remember that the species that have a very close common ancestor are closely related and the further away their common ancestor is, the less related they are.
So, as you can see in the picture shown in green, modern camels are very closely related to Eschiatus and distantly related to Stemylus, so the first statement is not true, but the second statement is (shown in red)
As you can see shown in light blue, the modern camel is very closely related to Camelops and the Aepycamelus is a distant relative, so the third statement is true.
Procamelus and Stenomylotus are more likely to share similar features ( statement 5, shown in brown) than Pliauchenia and Oxidatus ( statement 4, shown in purple) because their last common ancestor is closer.

Answer:
When the solutions (including inside and outside) were replaced by NaCl, the membrane potential changes from a negative value of -60 mV to a positive value of + 60 mV.
Explanation:
According to the Nernst equation the potential of the membrane for a two-compartment model of a cell for positive gradient of K⁺ ions is V = - 60 mVlogK'/K where K' = inside concentration of K⁺ ions and K = outside concentration of K⁺ ions. For a 10 fold excess of KCl in the inside compartment, K'/K = 10. So,
V = - 60 mVlogK'/K = - 60 mVlog10 = -60 mV.
For a negative gradient of Na ions is V = + 60 mVlogK'/K where K' = inside concentration of Na⁺ ions and K = outside concentration of Na⁺ ions. (Since the cell is selectively permeable to Na⁺ ions. So, Na ions to not flow out but in.)For a 10 fold excess of NaCl in the inside compartment, K'/K = 10. So,
V = + 60 mVlogK'/K = + 60 mVlog10 = +60 mV.
So, when the solutions (including inside and outside) were replaced by NaCl, the membrane potential changes from a negative value of -60 mV to a positive value of + 60 mV.
