yes they are
No, not all brains weigh the same. Brain weight can vary from person to person based on factors such as overall body size, genetics, and specific brain structures. On average, an adult human brain weighs about 3 pounds.
No, not all adult brains are the same size. Brain size can vary significantly among individuals due to factors such as genetics, sex, and overall body size. While average adult brain volume is typically around 1,300 to 1,400 cubic centimeters, individual variations exist, and size does not directly correlate with intelligence or cognitive abilities.
Human brains began to increase in size around 2 million years ago during the evolution of the genus Homo. This increase in brain size is associated with the development of more complex cognitive abilities and the emergence of early human species like Homo habilis and Homo erectus.
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.
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.
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!
No, all plates are not the same size
Yes, all arthropods have brains.
No, human hearts do not all weigh the same. The weight of a human heart can vary based on factors such as age, gender, and overall body size. On average, an adult human heart weighs about 250-350 grams.
it is the same as our brains work it sends messages to all around the body.
are all nuclei the same size( diameter
