yes they are
because of the evolution, it is a nature process of all beings.
No Not All Brains Weigh The Same.Newborns Have Undeveloped Brains That Are About 1-2 Pounds. When The Brains Are Fuly Developed They Are About 3-5 Pounds.
No, they don't. There are over 200 different types of cells in a human body. All have different functions and different sizes and shapes. But, each type is of the same size in every human. For example, the muscle cells would be of the same size in all the humans. the red blood cells are different from the muscle cells in terms of their function and their size and shape; however, all human will have the same size of red blood cells. Hope that helped..
With a heart the same as you do... same as all mammals do.
Animal brains vary in size, and cannot "think" like human brains can. With the different habits and knowledge, they can not process many human objects. People say that animals' brains are tiny,but some are even smarter than humans!
Some brains are larger than others, and often a larger brain is connected with higher IQ. However, intelligence is more about the ability to make connections, and brain size would only increase the capacity for memory space rather than speed.
Bones are different for everyone. The size of bones in the body differs from person to person.
because brains have unknown electrical signals & radio waves, and they don't all work the same, and God had to leave the reward of that knowledge for the here~after
No, all plates are not the same size
No, all plates are not the same size
All humans (aside from those with brain differences due to injury or disease) have the same brain structures of relatively the same size. What makes us different is the way our brains are "wired" which has to do with the stimulus we are exposed to, as well as genetic factors.
Yes, all arthropods have brains.
