Widespread use of pesticide has lead to the development of:
More pesticide-resistant insects.
Differentiation of large planetesimals and protoplanets: is the process by which these bodies develop internal layering. began with heating up component materials within these bodies. was caused by heat created by the transformation of kinetic energy from collisions into thermal energy.
One of the few advantages is In sexual reproduction, more variations are produced. So in turn this ensures survival of species in a population.
Answer: True
Explanation: Ion channels are very specific and are voltage gated channels. They are highly specific and selective for particular ions only.
Example: Some of the channels allow the flow of potassium ions but do not allow sodium ions to cross the membrane to maintain the concentration.
Some of the positive ion channels allow only the movement of positive ions and no negative ions. These channels are not always open and opens only when there is a concentration gradient.
