In humans gene flow usually comes about through the actual migration of human populations, either voluntary or forced. Although gene flow does not change allele frequencies for a species as a whole, it can alter allele frequencies in local populations.
Hopefully this helps.
Answer:
C. All projection maps are subject to varying types of distortion.
Explanation:
The only truly accurate representation of Earth is the globe, as earth is a sphere. When one tries to map out a 3-d sphere on a piece of paper, it is impossible without some kind of distortion occurring. This distortion happens with distance, size, and sometimes other factors. Different projections are used for different purposes because some are more accurate than others in terms of distance, size, relative position, etc.
Answer:
The correct answer is - can be explained by the law of dominance.
Explanation:
In this experiment of Gregory John Mendel where he made a cross between a purebred tall plant and a purebred dwarf plant and in the first generation all the offspring were tall.
It can be explained by that every offspring get one allele from both parents and in purebred both alleles are either dominant or recessive and both parent plant gives one allele which makes a heterozygous condition in which the dominant allele masks the recessive allele and offspring express phenotype of the dominant parent.
Correct option a) Increased plasma volume.
A potential negative health effect of stress is Shrinks the brain. Stress that's the left unchecked can contribute to many health problem, such as high blood pressure , heart disease , obesity and diabetes.
The volume of the brain tends to remain about the same, it has been found that chronic stress in healthy individuals can causes areas of the brain associated with emotions , metabolism and memory of that individual to be shrink slowly.
Stress can also be positive which is distress , getting job promotion or being given grater responsibilities keeping us alert and ready to avoid danger. It can became negative if a person faces continuous challenges without relief or relaxation between challenges.
