The correct answer is - A. A few centimeters a year.
Earth's crustal plates move very slowly, between 2 cm and 5 cm (depending on the plate) annually. This is the reason why it takes millions of years for them to significantly change their position, and with it the appearance of our planet. These crustal plates are slowly moving around the planet because they are powered by flow in the interior mantle.
<span>There are many indicators for predator presence. Some of them are:
Being able to spot predator marks like scratches or fur.
Being able to feel predator movements.
</span><span>Echo-location </span>For example, moths respond to the echo-location calls from their bat predators; moths drop to the ground once they hear the sound pulse from the bat.
=====|>WHAT DO YOU MEAN<|===== :/
In order for energy to be able to be created, ATP(adenosine triphosphate) needs to form in either photosynthesis or krebs cycle from ADP + P(from NADPH). When ATP is available, huge amounts of energy are released when needed by slicing one P atom from ATP So that it can again become ADP and undergo lots of processes to become ATP again. So energy is added from tearing of Phosphate Atom due to tearing of phosphoanhydride bonds. This is possible because of process known as hydrolysis, when ATP is in equilibrium with water and some electrons. And the process of ADP becoming ATP is recharging and occurs in mitochondria.
The processes are hydrolysis and rechargeation, but most important process is Krebs Cycle, where all of this happens.
