In recent molecular genetic studies, genes associated with the neurotransmitter Dopamine have been linked to ADHD.
ADHD stands for Attention Deficit Hyperactivity Disorder. People with ADHD have a hard time focusing on tasks. Scientists have found that the low levels of dopamine in the brain are associated with the symptoms of ADHD. It is because the neurons in the brain have a high amount of protein called the dopamine transporters. These proteins block the dopamine from passing between the neurons. This decreases the effect of dopamine.
The answer is in the picture attached.
I believe the answer is B
This is true, and while being the king’s cupbearer put his life on the line every day, it also gave him authority and a very high salary. Hope this helps.
The evolution is explained by principles of the natural selection is as follows:
1. Resources are scarce
2. There is a biological variation within all species.
3. There are more born that the available resources, hence competition.
4. Adaptation to the environment will likely aid survival
5. Environment will decide which is deemed fit
6. Those who are considered fit will have offspring, and those who arent will die out.
7. As time goes on, those with more successful adaptation will develop more mutation, later becoming a new specie.
When applied to the theory of evolution, our primate ancestors have developed mutation that were deemed more fit, thus creating a separate species that evolved to human beings.
