Answer:
Increase EDV and therefore, increase stroke volume.
Explanation:
EDV is the volume of blood which filled the ventricle before its contraction while ESV is the volume of blood remain in ventricle after ejection.
When venous return increases, this will increase the pressure on ventricle contraction which can lead to eject of addition blood returned to it.
So, increase in EDV results in an increase of stroke volume (SV).
Answer:Mutations are irreversible and are passed on to the daughter cells during mitosis. Certain genes are involved in the maintenance of normal cell growth patterns
Explanation:
Answer:
The correct answer is - As a person ages, scoliosis may develop resulting in an abnormal spinal curvature and shorter stature.
Explanation:
Scoliosis is a condition in which spine curvature towards the sides takes place before the puberty during growth period or spurt normally. The cause of this condition could be muscle dystrophy or palsy and similar condition.
This affects the stature of an individual but not affected by age as it remains constant normally after development or growth till puberty. All other conditions are associated with the short stature and influenced by the age.

7. D. best adaptations
8. C. survive and reproduce
Explanation:
Carrying capacity refers to the maximum population size of a species/population in a particular habitat. The carrying capacity depends on abiotic (e.g., shelter, water) and biotic factors (e.g., food, presence of mates). According to the evolutionary theory, individuals better adapted to their environments are more likely to survive and reproduce (i.e., produce more offspring) than other members of the same species. These 'better adapted' individuals will have more chances to pass their 'beneficial alleles' to the next generation.
