Answer:
D. trait formation due to behaviors
Explanation:
It is obvious to see that the three animals, cat, whale, and bat, have the same basic structure of their forelimbs, but also that they have developed differently and have taken a new shape. The reason for this is a trait formation due to behavior. The cats ancestors were terrestrial, and the cats have remained terrestrial, walking on their four legs, and having the same shape and function as their ancestors. The whales had similar forelimbs, but their ancestors started to move more and more in water. As they did, they needed more muscle power, but also greater width of the forelimb so that they can move more easily and more efficiently in the water. This behavior has gradually resulted in a flat, strong, peddle like forelimb. The bat too had similar forelimbs to that of the cat, but its ancestors started to try to fly. The process was gradual, and it started with jumping, then longer jumps, development of skin between the fingers, elongation of the fingers, thus provide more area for development of wider skin area. This has resulted in developing a light, wide, skin dominated forelimb with elongated fingers, providing flight for the bat.
Correct answer: Halftone
The halftone is a reprographic technique, which uses continuous imaginary tone by the use of dots, which vary in size or in spacing.
Example: The shades of gray in print are produced by breaking the image of the object into tiny dots that appear to blend into a continuous tone when viewed with a naked eye. Such a pattern of tiny dots is called a halftone.
Answer:
Ectoparasites are organisms that live on the skin of a host, from which they derive their sustenance. The phylum Arthropoda includes the two-winged, or dipterous, flies. The larvae or maggots of these flies may invade the living or necrotic tissue of animals and humans, producing myiasis. Multiple dipterous flies are thought to be capable of producing ocular myiasis. It is thought that the larvae are embedded in the eye, that they burrow directly through the sclera and then under the retina. Typically, they leave asymptomatic tracks throughout the fundus, but a number of cases of destructive endophthalmitis have been reported, particularly from Scandinavia.
Conclusion is the step of the scientific method explains why the results turned out the way it did.
<h3>What are the steps of scientific method?</h3>
There are seven steps of the scientific method which are the following:
1. Ask a question: The first step in the scientific method is asking a question that you want to answer.
2. Perform a research about the given topic.
3. Make your hypothesis. Hypothesis is a statement which may be true or false.
4. Test your hypothesis by conducting an experiment or a series of experiments.
5. Make an observation.
6. Do analysis about the results and draw a conclusion on the basis of given data.
7. Present the findings to the world.
So we can conclude that Conclusion is the step of the scientific method explains why the results turned out the way it did.
