Answer:
Maintains successful genetic combinations without modification.
Explanation:
Asexual reproduction usually creates perfect copies of the parent. If the parent is genetically sound creature, then a successful genetic combination is being reproduced and maintained without any changes or modification.
When the continents are at the Earths poles, they receive less sunlight.
Answer:
The receptors in the aortic and carotid bodies are chemoreceptors.
Explanation:
Chemoreceptors are specialized cells that are responsible for detecting and converting chemical signals into biological signals, to relay that information to the brain, where they will finally be interpreted. Among them we find the peripheral chemoreceptors, which are the aortic bodies, located along the wall of the aortic arch and innervated by the vagus nerve, and the carotid bodies, located in the neck. . Carotid bodies are stimulated by variations in the concentration of oxygen and carbon dioxide in the blood, as well as variations in blood pH. When the pH decreases the CO2 increases and the oxygen decreases, they activate the chemoreceptors to increase breathing.

Answer:
100% red kernel color
Explanation:
R_B_ = Red kernel color
R_bb and rrB_ = yellow kernel color
rrbb = white kernel color
True breeding red kernel x true breeding white kernel = RRBB x rrbb
F1 genotype ratio = 100% RrBb
F1 phenotype ratio = 100% red kernel color plant.
<em>The expected phenotype of the F1 plant is 100% red kernel color.</em>
