Answer;
-Our brains fill in gaps in our perception.
-If its been a long time since an event occurred, we might imagine things that did not happen.
Explanation;
-One way that our brain may alter sensory information is by filling in information that is not really there. For example a word in a sentence could have a missing word but we probably assume that word is there and keep reading the sentence.
-Another way is applying already known stuff into new situations. For example we have learned that if a dessert is pink, then it is strawberry flavored. If we saw a bowl of vanilla ice cream with pink food coloring, we may assume it's strawberry ice cream.
The short answer is that cells respond to the chemical environment in which they find themselves. The cells around them, the specific conditions, and feedback from the environment all create specific chemical cues that inform the cells to which genes should be expressed, and in what amounts. Chemicals include hormones, cytokines, general signaling molecules, such as cAMP, etc.
i literally hopped on google for this, lol.
i hope this helps though. :)
Answer:
The main difference between relative dating and radiometric dating is that relative dating is the method used to determine the age of rock layers according to their relative depth whereas radiometric dating is the method used to determine the absolute age with the use of decaying products of the natural radioactive. Also, absolute dating is more precise than relative dating because it tells the exact age of the fossils. Both are ultimately based on the fossils found in the strata.
