Answer:
The correct answer is - natural selection.
Explanation:
The change of an allele's frequency or microevolution in a particular population due to its fitness benefit it provides to the individuals of the population can be caused by the natural selection process. Relative reproductive success is a measure of Fitness.
The change of an allele's frequency in deleterious traits mostly decreases in a population and this process is known as adaptive evolution. There is no or very small number of relative reproductive success present.
Canal that connects the third and fourth ventricles is cerebral aqueduct (of Sylvius) canal.
<h3>What are the central canal?</h3>
The central canal, additionally known as the spinal foramen or ependymal canal, extends from the conus medullaris withinside the lumbar backbone to the caudal perspective of the fourth ventricle and is coated through a single layer of columnar ependymal cells . It represents the remnant of the lumen of the primitive neural tube.
The 3 ventricle is a slim, funnel-formed shape located among your proper and left thalamus, simply above your mind stem. The fourth ventricle is a diamond-formed shape that runs along your mind stem.

Answer:
They open the stomata during the day to collect light energy from the sun and carbon dioxide from the atmosphere, i.e adaptation.
Explanation:
Plants also responds to hormones such as abscisic acid that causes the stomata to close during stressful conditions. During the day the mesophyll in a leaf requires the stomata to open for exposure to sunlight and carbon dioxide. It closes at night when there is no sunlight to prevent water loss through transpiration in response to the turgidity of guard cells.
