According to the evidence scientists have gathered, whales and hippos are more closely related than whales and fish. Describe the types of evidence a scientist uses to infer whether two species such as whales and hippos share a common ancestor.

Answers

The type of evidence that scientists use to infer ancestry includes morphological, molecular, and embryological evidence, and the fossil record.

What is evolution?

Evolution can be used to describe descendence from a common ancestor of two or more species.

The presence of homo-logous structures is indicative of common ancestry between different species.

These homo-logous structures can be observed during the embryo stage of organisms and the observation of the fossil record.

Grassland ecosystems in Texas have evolved to depend on periodic fires to return nutrients to the soil and encourage plant reproduction. Humans have prevented fires in many of these grassland areas, resulting in plant and animal communities with little diversity. Wildlife biologists often recommend purposefully starting fires called prescribed burns, which are monitored and controlled, in grassland ecosystems every 3 to 4 years. These biologists observe greater diversity in plant and animal life in the years following a prescribed burn. What natural processes are the biologists attempting to imitate

Answers

Answer:

Succession

Explanation:

The biologists were attempting to imitate succession.

Succession refers to a gradual change to the structure and species composition of a community over a period of time.

A newly colonized environment such as a bare rock forms a community is said to be in primary succession. Thereafter, the structure and composition of the community keep changing until a relatively stable community, otherwise known as climax community, is established.

Secondary succession happens when a disturbed community tries to regain its original dynamics in terms of species composition and structure. A climax community is often less diverse than a community that is still in active succession.

Hence, the biologists were attempting to imitate succession by burning/disturning a relatively stable, less diverse climax community of grassland in order to realize a more diverse community that will undergo secondary succession.

D. North America has no volcancus.​

Answers

Explanation:

its b i think if its right your welcome if its not let me know

The evidence for continent drift theory is that places with hot climates once had glaciers. Therefore, option B is correct.

What is continental drift theory?

According to the Theory of Continental Drift, the continents of the Earth move relative to one another and appear to be drifting over the ocean floor together.

Wegener constructed a ring around the south pole using the regions that had been ice-covered. The conclusion of the theory is, Over the past 300 million years, the continents have drifted to their present locations after having formerly been a single, bigger continent.

The fit of the continents, the distribution of prehistoric fossils, rocks, and mountain ranges, as well as the placements of prehistoric climatic zones, were all used as evidence for continental drift. Hence, option B is correct.

The little blind children at the Perkins Institution had sent it and Laura Bridgman had dressed it; but I did not know this until afterward. When I had played with it a little while, Miss Sullivan slowly spelled into my hand the word "d-o-l-l." I was at once interested in this finger play and tried to imitate it. When I finally succeeded in making the letters correctly I was flushed with childish pleasure and pride. Running downstairs to my mother I held up my hand and made the letters for doll. I did not know that I was spelling a word or even that words existed; I was simply making my fingers go in monkey-like imitation. In the days that followed I learned to spell in this uncomprehending way a great many words, among them pin, hat, cup and a few verbs like sit, stand and walk. But my teacher had been with me several weeks before I understood that everything has a name. I left the well-house eager to learn. Everything had a name, and each name gave birth to a new thought. As we returned to the house every object which I touched seemed to quiver with life. That was because I saw everything with the strange, new sight that had come to me.Read the following excerpt from Narrative of the Life of Fredrick Douglass, by Fredrick Douglass.The plan which I adopted, and the one by which I was most successful, was that of making friends of all the little white boys whom I met in the street. As many of these as I could, I converted into teachers. With their kindly aid, obtained at different times and in different places, I finally succeeded in learning to read. When I was sent of errands, I always took my book with me, and by doing one part of my errand quickly, I found time to get a lesson before my return. I used also to carry bread with me, enough of which was always in the house, and to which I was always welcome; for I was much better off in this regard than many of the poor white children in our neighborhood. This bread I used to bestow upon the hungry little urchins, who, in return, would give me that more valuable bread of knowledge. I am strongly tempted to give the names of two or three of those little boys, as a testimonial of the gratitude and affection I bear them; but prudence forbids;not that it would injure me, but it might embarrass them; for it is almost an unpardonable offence to teach slaves to read in this Christian country.Q: Using the excerpts from the Story of My Life by Helen Keller and Narrative of the Life of Frederick Douglass, compare and contrast the themes presented by the authors. 8.43 divided by 12.654 The Aztec believed they needed to be descended from the Toltec in order to gain "respect" of neighbouring societies.
