What might account for individual differences in growth for a sample of 10 goldfish all grown in captivity?
Trick question : Both environmental and genetic factors heavily influence an organisms growth.
A process by which a population becomes better suited to its environment by increasing the frequencies of alleles that provide benefits to survival and reproduction.

inherited
Students raised two groups of the same type of bean plant. They gave both groups the same amount of water and sunlight. They treated one group with fertilizer. They observed that the fertilized plants, on average, were taller than the bean plants that had not been treated with fertilizer. How does this experiment show that environmental factors influence growth?
Answer must include that genetic factors were kept constant ( same type of bean plant ) and environmental factors ( food / fertilizer ) were changed.
A family went to the store and bought pumpkin seeds. One package was labeled " Baby Boo " and the other package was labeled "Kratos ". They planted the garden, and watered the seeds the same amount everyday. All pumpkin seeds received the same amount of sunlight and had the same soil quality. The baby boo pumpkins grew tiny pumpkins, and the kratos seeds grew massive pumpkins. How do we know that growth was influenced by genetic factors?
Answer must include that all environmental factors remained constant, while genetic factors were altered
