All planets have these same layers (From deepest to shallowest, inner core then the outer core, then the mantle, and lastly the crust. A good example is the Earth) that is shown in the diagram, even the sun has all the layers I just listed.
But, some planets I can think of are Mars, Venus, Moon, and the Earth of course.
Layer C. sounds like it could also represent Layer D, since they are so close.
P. S. I did my best to try to answer this.
Answer:
The key function of the mitochondria is to supply energy by the mechanism of aerobic respiration for cellular activity. Glucose is converted in the cytoplasm of the cell in this step to form pyruvic acid, which is transferred into the mitochondrion.
Explanation:
Like other organelles, by means of organelle-specific adaptors, mitochondria are linked to specific motor isoforms and their movement is vulnerable to degradation of these motors and adaptor proteins.
It is dry in deserts and hot too. There are special kinds of plants that grow in desserts means they have specialized characteristics which help them beat the dry and hot weather.
Succulent plants such as cacti, aloes, agaves have ability to store water in their leaves and stems which have thick and hard outer layer to avoid evaporation of water.
These plants have small spicules on their outer surface which protects them from animals as well.
