Symbiotic association means one of the organisms, called endosymbiont, is present inside the cells of its host. The most typical examples are endosymbiosis theory of mitochondria and chloroplasts which, according to some theories, are cellular organelles of bacterial origin.
But these theories are still discussed because there are in fact arguments that support endosymbiosis theory and also arguments that disapprove it.
Here are the answer for the exercise explaining the endosymbiosis
A ==> oxygen-using procaryote (before being a mitochondrion)
B ==> mitochondrion
C ==> Nucleus
D ==> endoplasmic reticulum
E ==> Host cell: ancestor of all eucaryotes
F ==> photosynthetic procaryote (before being a chloroplast)
G ==> chloroplast
H ==> Host cell: Ancestor for photosynthetic eucaryotes
Answer:
is more steeply sloped than the windward side
Explanation:
The wind is the primary agent that moves the sediments and creates sand dunes in the deserts. When the wind starts to slow down it loses its power to carry the sediments so it starts to deposit them. As it does, a hill of sand is starting to form, called a sand dune. The wind will constantly be bringing new sediments, and the windward side is the one that gets them, while the leeward side doesn't. This results in the windward side to be much larger, but also to have much lower angle of fall, while the leeward side is having a very steep slope as it is constantly building on the top, but not the rest of it.
