Complete Question: Julio wants to study the effect of water temperature on the hatching of fish eggs in a lake. which of these experimental designs would be most practical for julio?
a. he should put fish eggs in aquariums of lake water kept at different temperatures and observe.
b. he should build a computer model of fish eggs in a lake that has many different water temperature settings.
c. he should use cameras to observe fish hatching in the lake and temperature probes to monitor water temperature.
d. he should take water samples from lakes of different temperatures and observe for eggs and newly hatched fish.
Answer: is <em>a). he should put fish eggs in aquariums of lake water kept at different temperatures and observe. </em>
Explanation:
By viewing all four options the most accurate and near to possible is <em>option A. </em>Other three techniques are not doable and have higher chances of inaccuracy. The results fetch from other techniques will contain various error which results in wrong findings. Instead of studying and controlling whole lake water temperature, a sample of water lake should be taken and adjusted it's temperature accordingly under observation in a controlled and monitored environment. By doing so, the eggs can be monitored and observed under an adjusted temperature with full accuracy. Hence option A is more suitable and more realistic approach in finding the desired results.
The genotype depends if the purple flower is heterozygous dominant of homozygous dominant. But the total possible phenotypes available is 2, purple or red.
Answer:
The answer is probably going to be D
Explanation:
The reason is because there are only a little food and then you have a variation of the same spices.

Explanation:
Answer:
C. Document the number of honey-making bees per hive.
Explanation:
Among the given options, the only useful criteria towards the experimental design of honey production are to "document the number of honey-making bees per hive". We know that the increased number of animals would increase the workforce and thus increase the production of honey (direct relation). Therefore, this will give a direct assessment of honey production.
