Your answer would be D. The possible combinations of alleles in offspring based on the parents genetic makeup. The punnet square is basically used to determine what the outcome of an offspring would be.
Student 1’s methods would be more accurate, because the student would control more factors. Only one variable at a time (either temperature or acidity) would be tested on each group of worms. On the other hand, Student 2 is testing both factors on all the worms, which could make the results unclear.
In growth cycle maybe maturity or death
Flowering plants reproduce sexually through a process called pollination. The flowers contain male sex organs called stamens and female sex organs called pistils. Cross-pollination happens when the wind or animals move pollen from one plant to fertilize the ovules on a different plant.
A). Calculation: Given mass of Au * 1mol of Au/molar mass of Au= # of moles
;
57.01 g Au*1 mole of Au/196.97g Au=0.3 moles of Au. So the answer is 0.3 moles of gold(Au). Good luck on the rest, and message me on Brainly if you need more help. I'll be happy to.
