Question:
Fossils can be used to match up rock layers. As organisms change over time, they look different. Older fossils will look different than younger fossils. Some organisms only survived for a short time before going extinct. Knowing what organisms looked like at certain times also helps date rock layers. Some fossils are better than others for this use. The fossils that are very distinct at certain times of Earths history are called index fossils. Index fossils are commonly used to match rock layers. You can see how this works in Figure 2.30. If two rock layers have the same index fossils, then they're probably about the same age. After reading the above, is "Some organisms only survived for a short time before going extinct" the correct answer to the question "How can extinction help to date rock layers?"? OPTIONS:
- no
- yes

Answer:
yes

Question:
Taliban and American aid. After the September 11 attacks, it was necessary for conservatives to somehow explain away the fact that the US government gave 245 million dollars to the new evildoers du jour. Never mind the fact that authors such as Robert Scheer warned of aiding the Taliban as early as in May 2001. Never mind that they did so not out of some humanitarian motivation, but because of the Taliban's violent enforcement of the ban on opium poppies. Never mind that in a regime that is controlled by warlords, it does not matter who is authorized to distribute the aid -- the ruling regional warlords will seize control of it and use it to their own advantage. Never mind that this very argument has been used by hawks in opposition to sending humanitarian aid to Iraq's Saddam Hussein. Never mind that the Taliban continued selling opium in spite of the deal. Never mind that this is all documented on Michael Moore's website about the film. Gun homicides. Statistics are Moore's weakest point, and it is surprising that his critics don't dwell on them longer. That's because they know all too well that Moore is correct: The United States have a far greater homicide rate (both gun- and non-gun) than most other first world countries. His main mistake is that he does not use population corrected data, his second mistake is that he does not cite his sources (and, as you correctly point out, he probably uses different reporting methods for the different countries). A good comparison of international homicide rates can be found on the relatively neutral guncite.com website. After reading the above, is "Humanitarian aid" the correct answer to the question "What was the $245 Million in aid to the Taliban intended to be used for?"? OPTIONS:
- no
- yes

Answer:
no

Question:
Sometimes traits can vary from parent to offspring. These changes are due to mutations. Mutations are a random change. Mutations are natural. Some mutations are harmful. In this case, the organism may not live to reproduce. The trait will not be passed onto offspring. Others variations in traits have no effect on survival. Can some mutations be good for a living thing? Other mutations can have great benefits. Imagine being the first moth that can blend into its background. It would have a better chance of survival. A living thing that survives is likely to have offspring. If it does, it may pass the new trait on to its offspring. Thats good news for the offspring. The offspring may be more likely to survive. Mutations are one way living things adapt to new conditions. After reading the above, is "The mutations are not passed onto the offsprings" the correct answer to the question "What is the advantage of the death of organism with harmful mutations?"? OPTIONS:
- no
- yes

Answer:
yes
