Question

Activity :
Collect information about the evolution of brain of vertebrates and presented in the classroom. Explain the functions of various endocrine glands by representing and act like 'Why I Am Important?' Collect the information to justify the statement 'Human beings are intelligent and different from other animals' and present it in the classroom.

Answer 1

Endocrine glands are glands of theendocrine system that secrete their products, hormones, directly into the blood rather than through a duct. The major glands of the endocrine systeminclude the pineal gland, pituitarygland, pancreas, ovaries, testes, thyroid gland, parathyroid gland, hypothalamus and adrenal glands.

Answer 2

Evolution of Brain: brain has not expanded in isometric fashion but in alometric fashion. The size of brain to the size of the body is not symmetric in the mammals because the small bodied organs has a large brain while a large bodied organ like the blue whale has a small brain so their ratio of the body of the organism to the brain size is not on proportion. The human brain uses 2.5 petabytes or 2.5 million gigabytes of storage compared to computer science.
