cent Aa, and 64 percent aa. The climate changed abruptly and resulted in the death of all homozygous recessive dinosaurs (s = 1). In the next generation, the recessive homozygotes died shortly after birth. What percentage of these newborn dinosaurs died? Show Calculation

Answer:

C) 19.7%

Explanation:

The new population distribution after climate change wiped out homozygous recessive dinosaurs is:

AA = \frac{4}{4+32}=\frac{1}{9}

Aa = \frac{32}{4+32}=\frac{8}{9}

The percentage of offspring of this new population that are homozygous recessive is given by:

P(Aa\ x\ Aa) = \frac{8}{9} *\frac{8}{9} =\frac{64}{81} \\P(aa) = \frac{1}{4}\\P(Aa\ x\ Aa) \cap P(aa) = \frac{64}{81}*\frac{1}{4} =0.197=19.7\%\\

19.7% of these newborn dinosaurs died

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.
