The most common type of mechanical weathering that occurs in mid-latitude is called frost action/frost shattering/freeze and thaw weathering. this type of weathering occurs in mountainous areas of mid-latitude regions, where the temperature fluctuates around zero degrees. When water from snowmelt or rainfall freezes in cracks in rocks it expands. The continuous expansion and contraction of rocks as water freezes and thaws will eventually cause rocks to break off into angular fragments.
Answer:
Animals engage in characteristic behaviors that increase the odds of reproduction. Animals and plants develop characteristic structures and behaviors to help them survive in their environment and pass on genetic information to their offspring. It is important that the offspring be cared for and protected so they can grow to adulthood and reproduce.
Answer:
the answer is D) DNA and RNA
C. 135135 in. Is right.
<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>
