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 correct answer is Separating soils by grain size. Among all the other choices, this is the aspect of soil characteristics in which a soil triangle is used for. Thank you for posting your question. I hope this answer helped you. Let me know if you need more help.

Answer:
The given statement is false.
Explanation:
The lateral gene transfer of the horizontal gene transfer refers to the movement of the genetic substance between the multicellular and unicellular organisms other than by the vertical transmission of DNA to the offspring from the parent. Horizontal gene transfer is essential for evolution in several organisms. The mechanism is common among the prokaryotes like bacteria and is accountable for bacterial drug resistance.
On the evaluation of certain sequences of DNA, it has come to know that horizontal gene transfer also takes place in eukaryotes from the mitochondrial and chloroplast genomes to the nuclear genome. One of the examples is that plants possess the tendency of getting genetic information from viruses.
