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.
Following are the response to the given points:
- Hawks possess greater vision, which allows them to compete less effectively and successfully; those with better vision have a better chance of acquiring food.
- Improved eyesight, in my view, is the most significant reason for living.
- Individuals with stronger eyesight have a better probability of survival.
- The prevalence of the population would rise over time.
- Hawks with greater eyesight but weak wings will not have the same advantage as those with regular eyesight and wings.
<h3>What did hawks evolve from?</h3>
They evolved from a group called the theropod dinosaurs that contain bipedal carnivores such as Tyrannosaurus rex and Velociraptor.
Thus, this is the answer.

Photosynthetic organisms use sunlight to provide the energy necessary to combine carbon dioxide and water to form organic molecules and ATP. Those same photosynthetic organism also use cellular respiration to breakdown those organic molecules whenever there is an energy demand greater than what can be provided by photosynthesis or in the absence of light.
