Can somone help me to answer 2 question after watching a video, Thank you https://www.youtube.com/watch?v=M18HxXve3CM 1)What is one interesting or surprising thing you learned from the video you watched? 2)It’s unlikely that you personally hunt wolves or whales, and equally unlikely that you are responsible for importing rabbits and foxes to Australia as shown in these videos. But your actions do affect ecosystems. What is one thing you can start doing or stop doing right away to help protect the earth’s ecosystems? Explain how the thing you chose helps to protect ecosystems.
The human AMY-1 gene encodes salivary amylase, an enzyme that breaks down starch. The number of copies of this gene varies, and people who have more copies generally make more of the enzyme. In addition, the average number of AMY-1 copies differs among cultural groups. George Perry and his colleagues hypothesized that duplications of the AMY-1 gene would confer a selective advantage in cultures in which starch is a large part of the diet. To test this hypothesis, the scientists compared the number of copies of the AMY-1 gene among members of seven cultural groups that differed in their traditional diets. The Figure shows their results. Starchy tubers are a mainstay of Hadza hunter-gatherers in Africa, whereas fishing sustains Siberias Yakut. Almost 60% of Yakut had fewer than 5 copies of the AMY-1 gene. What percentage of the Hadza had fewer than 5 copies?

Consider the two passages below. Which one do you agree with, and why? Support your argument using examples from experience and observation. In approximately one paragraph, defend one position, then refute the other. Or take a position somewhere between them and explain your point of view. In The Omnivore’s Dilemma, Michael Pollan quotes a food industry executive, Gene Kahn, regarding our food choices: “This is just lunch for most people. Just lunch. We can call it sacred, we can talk about communion, but its just lunch.” In Just Food, James McWilliams “offer(s) a vision of sustainability that assumes that, as socially conscious consumers, we’re prepared to take on more complexity in the quest to achieve an environmentally responsible diet.”
Which one of the following is not a consumer? omnivore carnivore decomposer herbivore

In approximately one paragraph, discuss at least two examples of how our biological evolutionary history is relevant to the ecology of human food production and consumption. Your examples should be grounded in the Spencer Wells reading and film assignments from this module. Try to relate these examples to your own life experience (and/or your own body of knowledge beyond this course).
The lynx numbers do not always lag behind (see 1875 & 1885 in figure). What is missing from the basic hare -> lynx food chain that could explain this?
