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.
Answer:
The sporophyte body comprises a long stalk, called a seta, and a capsule capped by a cap called the operculum. The capsule and operculum are in turn sheathed by a haploid calyptra which is the remains of the archegonial venter. The calyptra usually falls off when the capsule is mature.
An embryonic stem cell is the first cell in the embryo, this is what creates a human and helps more cells to form.
Answer:
<em>The correct option is D) Diane will have to travel a farther distance to move the chair.</em>
Explanation:
To slide the chair up an inclined path, Diana would have to travel a further distance. While using the ladder to reach the second floor window would have made the distance smaller, but more force would have been required to move the chair through climbing a ladder. Diane would have got easily exhausted for moving the chair across the ladder. Using the inclined path will make the distance farther but as much force would not be required in this process. Hence, the method of using an incline is better.
