Answer: A. Genotype: 1/2 Yy; 1/2 yy. Phenotype: 1/2 Yellow; 1/2 Green.

Explanation: The answer lies in Punnett´s Square. A visual representation of Mendelian inheritance. Dominant genes always express when an organism presents them. Recessive genes express when both alleles contain the recessive gene. A heterozygote contains different alleles for the same gene (Yy). A homozygote contains the same alleles for the same gene (YY/yy), which can be a Dominant (YY) or Recessive (yy) Homozygote.

joja [24]

Answer:

The correct answer is - B) Elysia Chlorotica grows when exposed to light in the absence of other food sources

Explanation:

If placing Elysia Chlorotica in presence of the food sources in the presence or absence of light it still grows as normal. However, if placing in the light in absence of the food sources it should not grow if it is not able to perform photosynthesis but it does which means there is a photosynthesis process also involve in the Elysia.

Photosynthesis is the process that involves the production of energy and nutrition in presence of light with water and atmospheric carbon dioxide.

Together, inhalation and exhalation are referred to as ________. together, inhalation and exhalation are referred to as ________
Gennadij [26K]
Together, inhalation and exhalation are referred to as breathing. Inhalation is the process of breathing where air moves into the lungs through the nose and the mouth. This causes an increase in the volume of air in the lungs, meaning the pressure will decrease, thus the air then moves to the lungs. Exhalation on the other hand is the flow of the breath out of an organism, for example in humans it is the movement of air from the lungs out of the airways, to the external environment during breathing.
