Limestone is easily dissolvable by water and often a small steam or even river and carve away at the stone and create caverns or caves
The phrenic nerve, which controls the diaphragm
I'm pretty sure the blank is underneath. Hope this helped. Have a great day! :D
Answer:
The enzyme shows increased activity up to a certain temperature.
Explanation:
An enzyme is mostly a protein molecule/a biologist catalyst that speeds up the rate of a chemical reaction in a cell.
Enzymes lower the reaction's activation energy by attaching to the reactant molecule and positioning itself in a manner that readily facilitates chemical-bond breaking and forming process.
As the temperature increases, the rate of enzyme catalyzed reaction increases up to a maximum level (optimum temperature) and then decreases abruptly with any further temperature increase.This optimum temperature is 40°C for most animal enzymes.The abrupt decline in the rate of reaction after the optimum temperature is caused by the denaturing of enzymes by temperatures above 40°C.
The correct answer is (d) all of the above.
The most important phenomenon of the earth's crust is that it is not stable. It keeps on changing with respect to time called as continental shift. Continental shift squashes and changes a continent in such a way that it is very hard to find out its early history. Continental shift results in earthquakes, volcanoes and tsunamis. The movement of tectonic plates is the main reason for continental shift which leds to the natural calamities such as volcanoes, earthquake and tsunami on the local environment.
