Brain can process and store lot of information. Large brains means large heads, which makes childbirth more difficult and painful for human mothers.
Explanation:
A larger brain provides better performance. human brain size increases rapidly. Human brains are larger, more complex brains which enabled humans of this time period to interact with each other and with their surroundings in different ways.
The prefrontal cortex is slightly a larger part in the human brain. Humans have the largest cerebral cortex. It is a sheet of brain cells that folds itself multiple times in order to fit inside the skull. It enables us to process everything we see and hear and think.
The right answer is C.
During inflammation, under the influence of chemical mediators, endothelial cells (forming the blood vessels) become activated. This leads to local arteriolar vasodilation then capillary2 which causes:
** an increase in blood supply
** a decrease in the speed of blood flow
This local swelling of the blood vessels causes redness and the sensation of heat. It aims to increase the flow of blood to evacuate dead cells and toxins (detox) and provide the elements necessary for healing, including white blood cells to fight against foreign bodies.
If the inner lining of the air sacs neither thin nor highly vascularized, then it can be inferred that AIR SACS ARE CANNOT BE THE SITES OF GASEOUS EXCHANGE BETWEEN AIR AND BLOOD. Air sacs are generally lined with mucus and surrounded with blood capillaries.
In case of birds, air sacs play an important role in respiratory system.
By the first distance, I'd say Venus (0.72 AU)
By the second distance, I'd say it's Saturn (9.54 AU)
But you also say it has no visible rings so the answer is VENUS.
Hope it helped,
Happy homework/ study/ exam!
