The carbon 14 left from this animal is 3 grams of 24 grams which is: 3g/24g= 1/8 times of its original mass. Then, the age of the animal fossil would be:
final weight= initial weight * (1/2) ^ time/half-live
1/8 initial weight = initial weight * (1/2) ^ time/half-live
log2 1/8= log2 (1/2) ^ time/half-live
-3= -time/half-live
time= -3 * -(half-live)
time= 3 half-live
If the half-live is 5730 years, the age would be: 3* 5730= 17.190 years.
1. <span> A. The algae directly feeds the large-mouth bass and wood duck. Consumers are the same thing as heterotrophs.
2. </span><span>The blue arrow points to an animal which gets all its energy from (i.e., eats) only other animals
3. </span><span>Primary consumers are the organisms which eat producers. So without the primary consumers eating the producers, the number of producers will probably increase.</span>
1. Describe - the first goal is to observe behavior and describe.
2. Explain - While descriptions come from observable data, psychologists must go beyond what is obvious and explain their observations. In other words, why did the subject do what he or she did?
3. Predict - Once we know what happens, and why it happens, we can begin to speculate what will happen in the future.
4. Control - Once we know what happens, why it happens and what is likely to happen in the future, we can excerpt control over it
5. Improve - Not only do psychologists attempt to control behavior, they want to do so in a positive manner, they want to improve a person’s life, not make it worse.

they are nursed by their mothers
