Answer:

D. her skeleton was 40% intact and undisturbed

Explanation:

Lucy was one of the most important discoveries in human evolution. Before the finding of Lucy majorities of the human ancestor bones were not much more than only some bone fragments.

Lucy was the first most complete Australopithecus which was ever found. Lucy was approximately 40% complete fossil. It was found that her brain size was smaller than today's man but she was bipedalism. She was a new species of Australopithecus- Australopithecus afarensis. So the right answer is D.

Why do some birds have bright colors while others look more camouflaged
Alika [10]
Male Birds are usually the colorful birds to attract mates while females are camouflaged to protect their eggs/hatchlings. Ground birds need to be camouflaged because they are easy prey and they have their nests on the ground.

Site-specific recombination systems _________. Multiple Choice do not depend on extensive nucleotide sequence homology depend on
professor190 [17]

Site-specific recombination systems all of the choices are correct i.e.

A. do not depend on extensive nucleotide sequence homology.

B. depend on enzymes that are often specific for sequences within the host.

C. are features of some viruses.

  • An exchange between two specified sequences (target sites), either on the same DNA molecule or on two separate DNA molecules, is known as site-specific recombination.
  • DNA sequences may be integrated, excised, or inverted as a result of the exchange.
  • A site-specific recombinase that can work by itself or with the aid of additional components or enzymes shapes the DNA target during recombination.
  • The recombinase is chemically bonded to the ends of the intermediate DNA after DNA breakage at the recombination site; when this process is reversed, the intermediate DNA is resealed to form the recombinant and the recombinase is released.
  • During this recombination process, neither replication nor repair are necessary.
