The "Spanish" influenza pandemic of 1918–1919, which caused ≈50 million deaths worldwide, remains an ominous warning to public health. Many questions about its origins, its unusual epidemiologic features, and the basis of its pathogenicity remain unanswered. The public health implications of the pandemic therefore remain in doubt even as we now grapple with the feared emergence of a pandemic caused by H5N1 or other virus. However, new information about the 1918 virus is emerging, for example, sequencing of the entire genome from archival autopsy tissues. But, the viral genome alone is unlikely to provide answers to some critical questions. Understanding the 1918 pandemic and its implications for future pandemics requires careful experimentation and in-depth historical analysis.
<span>The correct answer is 'secondary consumer’. This is because the yellowfin tuna eats herbivorous fish (these are primary consumers - they only eat plants, which are producers) and take refuge from predators. This shows they are not tertiary consumers, as tertiary consumers are at the top of the food chain.</span>

<span>The first three scientific inquiry is being related because
they are all equivalent to the facts of finding emission.
They develop a question that must be answered.
1. The first scientific inquiry is to pose a question or else a problem is being investigated.
2. The next step is the observation, and it helps to form a hypothesis which explains the phenomenon or effect of what is observed.
Scientific inquiry is the diverse ways in which scientist study the natural world and then propose the explanations which are based on evidence which is derived from their work. Also, students develop science ideas of knowledge and understanding how scientist they do study the natural world.</span>
Answer: No
Explanation:
the freezing point of salt water is lower than that of pure water, due to the presence of the salt dissolved in the water
