Most likely to be A which is probably an artery which carries blood away from the heart Nd tens to carry oxygen rich blood
the leg doesnt contain aveoli this is found in the lungs so its not B
since its oxygen rich little carbon dioxide will be present in this structure so its not C
this part cant be part of the respiratory system as the respiratory system includes lungs, mouth and etc but not the legs so it cant be D
hope that helps
The correct answer is: stratosphere.
This is because their temperatures are rising instead of decreasing.
There are 4 primary layers of the atmosphere on Earth:
Troposphere (6-20km), the layer that we live in, where the weather occurs. Only nitrogen and oxygen present.
Stratosphere (20-50 km), where the airplanes fly, contains the ozone layer, which absorbs harmful radiation from the sun.
Mesosphere (50-85 km), the coldest region of Earth’s atmosphere (-100 C), protective layer
Thermosphere (80-690), the hottest (1500 C) and the thickest layer which consists of the ionosphere and the exosphere.
The principle is called CEPHALOCAUDAL PRINCIPLE.
This principle proposed that growth follow a particular pattern in which the head and the upper part of the body grow first before the growth proceeds to other part of the body.
