The graph shows, in a period of time between 1978 and 2010. Therefore, it's related to the last 50 years, not the last 100 years, meaning that alternative D is wrong. The amount of sea ice shown in the graph is shown in the scale of million square miles. So, as the graph shows an initial value around 3.2 (3 millions and 2 hundred miles) and it ends up in a value around 2.2 (2 millions and 2 hundred miles), still the real values are around 2.8 (2 million and 8 hundred thousands initially) and 2.0 (2 millions at the end), having a lower value of 1.8 (1 million and 8 hundred thousand); So, in both scenarios, arctic sea ice has shrunk by 1,000,000 (1.0) square miles, being under 2,000,000, not over. Therefore, the highest number to be inside this amount is 2,000, so the correct answer is A: Arctic sea ice has shrunk by over 2,000 square miles in the last 50 years.

<span>Since protists are eukaryotes are eukaryotes, their chromosomes are contained inside a nucleus, which must break down then reform for conjugation to occur. Bacteria lack a nucleus, so division and exchange of genetic material is simpler.</span>
<span>The question is 'organisms interact with each other and their environment in different ways. What is an organism's niche. A particular organism ecological niche is defined as that organisms roles in its particular environment. It covers all the ways in which the organism affect its physical environment and the other organisms that are cohabiting the environment with it, that is, the function of the organism in its environment and its interrelationships with all the biotic and abiotic factors present in its environment.</span>
