The answer is D: <span>What is the relationship between an increase in the tick population and the death rate of the moose and wolves? The graph shows an inverse relationship between the number of moose and wolves: an increase in wolves results in a decrease in moose and vise versa. The scientists want to assess the impact of ticks on this relationship. Therefore, only aim D is valid.</span>
Answer:
Wind, water, and ice erode can shape the land.
Explanation:
Volcanic activity and earthquakes alter the landscape in a dramatic and often violent manner. And on a much longer timescale, the movement of earth's plates slowly reconfigured oceans and continents. Each one of these processes plays a role in the Arctic and Antarctica.
Genes encode proteins and proteins dictate cell function. Therefore, the thousands of genes expressed in a particular cell determine what that cell can do. Moreover, each step in the flow of information from DNA to RNA to protein provides the cell with a potential control point for self-regulating its functions by adjusting the amount and type of proteins it manufactures.
At any given time, the amount of a particular protein in a cell reflects the balance between that protein's synthetic and degradative biochemical pathways. On the synthetic side of this balance, recall that protein production starts at transcription (DNA to RNA) and continues with translation (RNA to protein). Thus, control of these processes plays a critical role in determining what proteins are present in a cell and in what amounts. In addition, the way in which a cell processes its RNA transcripts and newly made proteins also greatly influences protein levels.

<span>In bacteria, DNA polymerase adds an incorrect base to a growing strand of DNA about once in every 100 000 bases added. The result is a mismatch such as the pairing of A with C.
