Sure I'll see what I can do. what is the questions and answer choices?
Explanation:
Environmental scientists are often interested in evaluating both species richness and species evenness, so they have come up with miles
species diversity that take both measures into account. One commonly used index is Shannon's index of biodiversity. To calculate this index,
we must know the total number of species in the community (s) and, for each species, the proportion of the individuals in the community that
represents that species (p). Once we have the information, we can calculate Shannon's index of diversity (H) by taking the product of each
proportion (0) and its natural log (In ()) and then summing these products, as indicated by the summation symbol (E):
H-- pin(p)
where
H = the Shannon index value
P, = the proportion of individuals found in the ith species
In = the natural logarithm
S = the number of species in the community
The minus sign makes the index a positive number. Higher values of Hindicate higher diversity
Note: the book uses "n" and the formula I found online uses "s" for the number of species in the community.
Imagine a community of 100 individuals that are evenly divided among four species, so that the proportions () of the species all equal 0.25.
We can calculate Shannon's index as follows:
• H = -((0.25 x In 0.25) + (0.25 x In 0.25) + (0.25 x In 0.25) + (0.25 x in 0.25)]
• H-[(-0.35)+(-0.35) + (-0.35) + (-0.35)]
• 1.40
Now imagine another community of 100 individuals that also contains four species, but in which one species is represented by 94 indiviudals
and the other three species are each represented by 2 indivudals. We can calculate Shannon's index to see how this difference in species
evenness affects the value of the index:
• H = -[(0.94 x in 0.94)+ (0.02 x In 0.02) + (0.02 x In 0.02) + (0.02 x in 0.02)]
• H=-[(-0.06) + (-0.08) + (-0.08) + (-0.08)]
• 0.30
Because this value of His lower than the value we calculated for the first community, we can conclude that the second community has lower
diversity. Note that the total number of indiiduals does not affect Shannon's index of diversity, only the the number of species and the
proportion of individual within each species matters.
Your Turn
Imagine a third community of 100 individual in which those indviduals are distributed evenly among all the species, but there are only two
species, not four. Calculate shannon's index to see how different in species richness affects the value of the index

How do genetics (genetic predisposition) and the environment work together to cause substance abuse in individuals? What is the likely role of epigenetics in this process?
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.

Answer:
The fertility rate measures the number of births per 1,000 women of childbearing age (ages 15 to 44) occurring in a particular year; birth rates refer to this measure within particular age groups.
Explanation:
The measure of the average number of children who are born to women of childbearing age in the population is called the fertility rate.
What is the population?The population is the portion that can be characterized as the total number of people residing in a given area or nation. These individuals are those who are mortal or alive.
The number of births to women of a certain range throughout the year expressed as a percentage of the average yearly headcount of women of such an age is known as the fertility rate of a certain age.
At a certain age the women's fertility rate is the highest and after that age has passed the rate of fertility is reduced. The number of birth per year with respect to the women of the fertility age is important to determine it.

Answer the following in several complete sentences:
How do external cues, internal emotions, and order of appearance influence memory retrieval?
Answer:
External cues activate associations that help us retrieve memories; this process may occur without our awareness, as it does in priming. Returning to the same physical context or emotional state (mood congruency) in which we formed a memory can help us retrieve it. The serial position effect accounts for our tendency to recall best the last items (which may still be in working memory) and the first items (which we've spent more time rehearsing) in a list.
Explanation:
i took the test?
The three ways that information can be retrieved from your long-term memory storage system are recall, recognition, and relearning.
What is the difference between external cues, internal emotions, and order of appearance that influences memory retrieval?External cues elicit feelings and memories because they are similar to past events or things we have seen.
Typically, exterior stimuli and experiences serve as triggers for internal emotions. An external event (such as the unexpected loss of a loved one) will be more deeply etched in memory if it has a significant emotional component.
In all other respects being equal, the hippocampus stores short-term memories in the cortex, where they are stored for a longer period, and preserves memories in a sequential order of appearance. Thus, we frequently remember things in the same order.
Memory retrieval is generally prompted by external cues and other memories. It helps us make sense of and respond to external events. It helps us think things through by connecting related memories.
