<span>Answer: Opening of Na+ and K+
Explanation:
Acetycholine binding opens Na+ and K+ ion channels in the receptors that allow simultaneous passage of Naâş into the muscle fiber and Kâş out of the muscle fiber. More Naâş ions enter than Kâş ions exit, which produces a local change in the membrane potential called the end plate potential.
Binding of acetycholine to receptor proteins opens Na+ and K+ channels resulting in jump in resting membrane potential(RMP) from -90mV to +75mV forming an end-plate potential (EPP).</span>
        
             
        
        
        
Genetically modified organisms are those organisms in which certain gene is inserted to get the desired beneficial results.
Explanation:
A genetically modified organism is an organism or plant altered for beneficial traits which would not have been possible by the traditional mating process or recombination techniques.
Genetic engineering is the technique involved for the construction of gene of interest and inserting them in the host species for getting expressed.
Many fruitful results have come out like a tomato of long shelf life k/a flavr savr.
Apart from molecular techniques used for cloning, CRISPR is the recent innovation which had made it very simple.
The GMOs can solve the food problem of the world as Single-cell proteins and longer shelved life food.
Disease resistant plants can be formed for better yields.
Nutrition level of food can be increased.
Example of GMO are canola, corn, papaya, soy and many animals are also on the list.
 
        
             
        
        
        
Answer: The basic theme of whale evolution is the development of large animals from much smaller ancestors, and nowhere is this more evident than in the case of multi-ton sperm and gray whales, whose ultimate forebears were small, dog-sized prehistoric mammals that prowled the riverbeds of central Asia 50 million years ago. Perhaps more intriguingly, whales are also a case study in the gradual evolution of mammals from fully terrestrial to fully marine lifestyles, with corresponding adaptations (elongated bodies, webbed feet, blowholes, etc.) at various key intervals along the way.
