Some of the existing genes of an organism mutated randomly. Below shows the DNA sequence before and after. Before: ATC GUT AT AGGA CTC
After:
ATC GUT A GG ACTC
What will most likely be the result of the above mutation?
O A. The ribosome will not create proteins using this gene sequence.
OB. The organism will lose some of its traits.
O C. Different proteins than before will be produced.
O D. The ribosomes will try to fix the DNA sequence.

Which of the following correctly list the first appearance of organism in the fossil record from earliest to most recent

On a recent expedition to a remote region of northern canada, scientists uncovered skeletal remains from about 100,000 years ago. surprisingly, all the skeletal remains, which included many species from differing biological families and spanned about two thousand years, showed evidence of experiencing temperatures in excess of 1000 degrees fahrenheit (or 538 degrees celsius). which of the following, if true, best explains the apparent paradox between the cold environment and the evidence of the bones experiencing hot temperatures? (a) chemical changes that naturally occur during the process of decay in only one north canadian species produce the same evidence of the species' skeletons being exposed to hot temperatures as the expedition scientists found. (b) a little over 103,000 years ago, a large fire is known to have occurred in northern canada. (c) strong evidence exists that as early as 70,000 years ago, homo sapiens around the world relied heavily on fire to cook animals. (d) in the same expedition and in roughly the same layer of excavation, scientists found rudimentary wood cutting and hunting tools used by early humans.

Consider the model of the oxygen cycle on earth. the majority of earth's oxygen reservoirs are found in the a) atmosphere. b) biosphere. c) hydrosphere. d) lithosphere.
