What is evolution?

Evolution refers to a series if gradual and cumulative and transferrable changes which occur in organisms that resulted in the formation of new species from existing species.

Factors affecting evolution include;

gene flow,the rate of mutation andnatural selection.

When there is less gene flow between populations as well as higher rate of mutation, evolution of species will be most like likely.

Therefore, between the s0 and s1 or the s0 and f1 population, evolution will be observe most likely in the population with less gene flow and higher rate if mutation.

The brain dysfunction associated with autism spectrum disorder (ASD) can sometimes involve the cerebellum and sometimes involve the frontal cortex.
a. True
b. False

Answers

The answer to this question is A

a. True is the correct answer.

What is ASD?

Autism spectrum disorder (ASD) is a neurodevelopmental disorder that affects communication, social interaction, and behavior. The exact cause of ASD is not fully understood, but it is believed to involve a combination of genetic and environmental factors.

Brain imaging studies have shown that individuals with ASD often have structural and functional abnormalities in several areas of the brain, including the cerebellum and frontal cortex.

The cerebellum is involved in motor control, balance, and coordination, but research suggests that it may also play a role in higher cognitive functions, such as language, attention, and social interaction. The frontal cortex, on the other hand, is responsible for a range of executive functions, including decision-making, planning, and impulse control, as well as social cognition and emotional regulation.

The dysfunction associated with ASD in these brain regions can manifest in different ways, depending on the individual. Some individuals with ASD may have difficulty with motor coordination and balance, while others may have trouble with language and communication.

Some individuals may exhibit impulsivity, while others may struggle with social interaction and emotional regulation. Therefore, it is true that the brain dysfunction associated with ASD can sometimes involve the cerebellum and sometimes involve the frontal cortex.
