yes they are
because of the evolution, it is a nature process of all beings.
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.
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
Bones are different for everyone. The size of bones in the body differs from person to person.
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.
No, all plates are not the same size
No, all plates are not the same size
Yes, all arthropods have brains.
No, cells arent all the same size. The size of a cell depends on the organism it belongs to and its function, for example a bacterial cell would be a maximum of around 10microns whereas an average human cell is between 10 and 100 microns, with size varying as I said dependant on function.
