If one parakeet is heterozygous, that means it has one dominant gene and one recessive gene (Rr). If the other is homozygous for white feathers, then it has two recessive genes (rr). Crossing these two in a punnet square gives you 50%.

Which description properly describes the plant structures involved in photosynthesis? Stomata take in water, sunlight, and carbo
erma4kov [3.2K]
The correct answer is that "xylem transports water, stomata take in carbon dioxide, and chlorophyll absorbs sunlight." The xylem is a vascular structure in plants that transport water, the phloem is another vascular structure in plants that transport nutrients. The stomata (singular; stoma) is the one responsible for the plants' gas exchange (takes in carbon dioxide, releases oxygen). The chlorophyll is what makes the green pigment of the leaves and mostly because of the presence of chloroplasts, the organelle in plant cells responsible for photosynthesis.
