B. How to solve operations with fractions and decimals
Hope this helps :)
Answer: I could be wrong but id say
Genetics is the study of genes. Genes are functional units of DNA that make up the human genome. They provide the information that directs a body's basic cellular activities. Research on the human genome has shown that, on average, the DNA sequences of any two people are 99.9 percent the same. However, that 0.1 percent variation is profoundly important. t accounts for three million differences in the nearly three billion base pairs of DNA sequence. These differences contribute to visible variations, like height and hair color, and invisible traits, such as increased risk for or protection from certain diseases such as heart attack, stroke, diabetes, and addiction. Genetics and lifestyle factors—such as diet, physical activity, and stress—affect high blood pressure risk. NIDA research has led to discoveries about how a person's surroundings affect drug use in particular. For example, a community that provides healthy after-school activities has been shown to reduce vulnerability to drug addiction, and data show that access to exercise can discourage drug-seeking behavior, an effect that is more pronounced in males than in females.
So are familiar with civilization adaption?
Are you familiar with emergence?
Google these two and read all you can in order to know the maximum of the begining of any society.
In history such as World History? You should be able to distinguish the trends and differences in different periods say "Period 1 vs. Period 2" where each period represents a different range of years (in AP World History I learned it with 6 periods but it varies from year to year of when it is taught)
