Afrcian people evolved in location with a warm climate so they did not need as large a brain for survival. They have larger sex organs and they are sexually mature at an earlier age than whites or asians. Cold winters of Europe or Asia caused people to develop the ability to start and control fires, and plan ahead by storing food. By contrast, in Africa food is readily available most of the year so they did not need complex thinking skills for survival. Blacks put less energy into parenting. This is seen in all african-derived populations where two parent families are rarely the norm. In a cold climate, people needed to put more planning, consideration and energy into raising a child because if they did not, the baby could easily freeze to death.
The results are quite obvious: Europeans discovered the Periodic Table of elements and developed complex symphonic music. Despite being located there for millennia, africans developed almost no technology or complex societies. This is not to say one race is better than any other but it is important to see that human racial differences exist for a reason.
would you expect skin cells to contain more or fewer mitochondria than muscle cell?
animalThey are also found in plant cells. But fewer than animal cells
It seems there might be a typo in your question. If you meant to ask which cells contain fewer organelles or specific components, it typically refers to prokaryotic cells, such as bacteria. Prokaryotic cells generally contain fewer organelles compared to eukaryotic cells because they lack membrane-bound structures, which allows them to reproduce quickly and efficiently. Additionally, the simplicity of their structure enables them to thrive in various environments.
No, older people generally have fewer cells than babies. As we age, the number of cells in our bodies may decrease due to factors such as cell death and reduced cell division. Babies, on the other hand, are growing rapidly, so they tend to have a higher number of cells compared to older individuals.
Prokaryotic cells have small ribsomes, no mitachondria, no nucleus and fewer organelles
That statement is not accurate or supported by any research. Political beliefs are complex and cannot be attributed to the number of brain cells. It is important to approach political differences with respect and understanding.
It depends on what you mean by drugs and the type of damage they do. I know that if your brain cells are killed, they will never come back. That's why sometimes people who are drug addicts seem to process slower: they have fewer neuron connections.
Well, there were fewer people left around to talk.
when a person has fewer red blood cells than normal his or her color is yellowish

People worked shorter days and fewer hours.
It is fact not supposition .
The fewer people that know, the better. There were fewer children at camp.
The brain is made up of two basic kinds of cells: neurons and glial cells. The human brain has about 100 billion neurons, according to some estimates (recent scientific experiments are now saying there may be fewer than that); the neurons are said to be assisted by trillions of glia, although again, recent scientific evidence indicates there may be fewer than once thought. But it remains a fact that neurons and glia depend on each other so that the brain will function properly. Neurons are the cells that relay messages about thinking, feeling, and doing. Glial cells perform a variety of brain functions: some make sure that electrical signals speed along the axon (a thin fiber with numerous branches that lead to distant parts of the body), others protect the neurons by defending against bacteria and viruses. Thus, while neurons often are better known, without the glia, the neurons would not work properly.
