Answer:
DNA is short for Deoxyribonucleic acid, more commonly known as DNA, is a complex molecule that contains all of the information necessary to build and maintain an organism. All living things have DNA within their cells. In other words, whenever organisms reproduce, a portion of their DNA is passed along to their offspring.

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.

Which of the following is evidence for continental drift?
A. There is one continent on Earth. .
B. Places with hot climates once had glaciers. C. There are no mountains in Africa.
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.

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.

Succession
