1. There is a clear correlation between the hare population and the lynx population across time. In particular, we see a correlation between the population sizes: An increase in the hare population is coupled with an increase in the lynx population, and vice versa. The time series population curves match one another in frequency but not in phase: The lynx population shows a slight lag compared to the hare population. The graph shows a cyclical fluctuation in the population. Finally, while perhaps a trivial observation, we see (and could have noted from the data table) that at no point in time is either the hare or lynx population zero. This is rather logical: As long as there are some members of a population alive, the population has the possibility of rebounding; if a population were to be completely extinguished (i.e., the population curve touches the horizonal axis), there would be such possibility, and we wouldn't see the sort of oscillation that we do.
2. A time series visualization of changes in two data sets allows one to track, analyze, and interpret relationships between the elements of the sets both individually and collectively. By graphing two sets of data on one graph, not only can one readily quantify the absolute differences between data from each set at a common point, but one can discern how the data change relative to each other across time. When the data sets are populations of predator and prey species, plotting both on a single time series graph allows one to quantify the populations of each at any given time as well as to compare the rate and magnitude of the changes in the absolute values of the each population within a common interval. Analyzing these parameters can help one discern any correlations between the population data, including (and perhaps most importantly) correlations that are characteristic of predator-prey relationships.
3. Lynx are specialist predators: Their primary prey is the hare. In other words, the lynx population subsists on the hare population. It's not surprising, then, that the number of lynx would be coupled with the number of hare. The greater the hare population, the greater the food supply for the lynx population. When hare are plentiful, the lynx can feed and reproduce: This results in a rise in the lynx population, which eventually results in a fall of hare population due to predation. In turn, the hare population is no longer sufficient to sustain the lynx population, so the lynx population then falls due to starvation. As the lynx population decreases, predation of the hare population also decreases; the lack of predation allows the hare population to reproduce and rise, which in turn replenishes the food supply for the lynx. This is a classic predator-prey population dynamic, and it bears out the correlation between the changes in the hare and lynx populations. Of course, in reality, there are many other factors that affect their population sizes; that's why there isn't a perfectly injective (one-to-one) correspondence in the oscillation between hare population decline and lynx population growth. But the predator-prey interaction here is significant enough to generate the sort of close coupling we see in the changes of their respective populations.

Where do plant cells obtain the energy required for the dark reactions?
A species of bird ate many types of seeds, each type coming from a different species
of tree. The birds' beaks varied in size, with some individuals having slightly smaller
beaks and others having slightly larger beaks.
slightly smaller beak
slightly larger beak
A few years went by without much rain, and the only species of tree that survived had
large seeds. Many generations later, almost all the birds had the slightly larger beaks.
How is this best explained?
Answer:
I took this in middle school option 3
Explanation:
Answer:
The bird most likely had to adapt so they had to eat whatever they could. Doing so made their beaks larger, the muscle under neath probably started to grow from all the movement trying to eat the large seeds. LOL i really dont know but it seem reasonable i guess.

The total wind power capacity in the united states in 2000 was about 2540MW. By 2015, the total wind power capacity in the United States was about 72,500MW Calculate percent change in the total wind power capacity in the United States from 2000 to 2015. Show the work
Answer:
2754.33% increase
Explanation:
The total wind power capacity in the united states increased between 2000 and 2015. The percent change in the total wind power capacity in the United States from 2000 to 2015 is given by the formula:
Percent change = [(total wind power capacity in 2015 - total wind power capacity in 2000) / total wind power capacity in 2000] * 100%
Percent change = [(72500 MW - 2540 MW) / 2540 MW] * 100%
Percent change = 2754.33% increase
Power is the amount of energy transferred or converted per unit of time. In the International System of Units, the unit of power is the watt, equal to one joule per second.
The total increase is 2754.33% increase
The total wind power capacity in the united states increased between 2000 and 2015. The percent change in the total wind power capacity in the United States from 2000 to 2015 is given by the formula:
Percent change = [(total wind power capacity in 2015 - total wind power capacity in 2000) / total wind power capacity in 2000] * 100%
Percent change = [tex]\frac{[(72500 MW - 2540 MW)}{ 2540 MW }* 100%[/tex]
After solving the equation the percent change = 2754.33% increase.

How does the body regulate dopamine
Answer:
Self discipline
Explanation:
Answer:
Inside the brain, dopamine plays important roles in executive functions, motor control, motivation, arousal, reinforcement, and reward, as well as lower-level functions including lactation, sexual gratification, and nausea. The dopaminergic cell groups and pathways make up the dopamine system which is neuromodulatory.
Explanation:
Striatal dopamine release is mediated by vesicular exocytosis. Active zone-like sites are required for rapid and efficient dopamine secretion. Localized dopamine release generates signaling hotspots and is powerfully regulated. Some striatal dopamine release is independent of ascending action potentials.
Why is sunlight necessary for photosynthesis?
Answer:
Sunlight provides the energy needed for photosynthesis to take place. In this process carbon dioxide and water are converted into oxygen (a waste product that is released back into the air) and glucose (the source of energy for the plant).

Describe three ways in which the atmosphere interacts with the geosphere.
Answer:
The atmosphere provides the geosphere with heat and energy needed for rock breakdown and erosion. The geosphere, in turn, reflects the sun's energy back into the atmosphere. The biosphere receives gases, heat, and sunlight (energy) from the atmosphere.

The green algae relate to land plants in the following ways:
They both have chloroplasts.Both have a cell nucleus.Both have a cell wall.Thus, the correct options are A, B, and E.
What are Green algae?Green algae may be defined as a type of eukaryotic organism that has photosynthetic pigments a and b. Such a type of algae also stores carbohydrates as starch.
Green algae mostly live in freshwater environments, ranging from unicellular flagellates to more complex multicellular forms.
Both land plants and green algae have a photosynthetic organelle known as chloroplast. The cell wall of land plants as well as green algae are made up of cellulose, hemicellulose, and pectins.
Both eukaryotic classifications possess a well-defined cell nucleus, nuclear membrane, and other membrane-bound cell organelles.
Therefore, the correct options for this question are A, B, and E.

Answer:
When the sperm and egg(ovum) fuse, their fusion is called fertilization.

What is the function of the structure identified by the red arrow? (2 points)
food capture
mobility
DNA transfer
Protection
Note about the question:
You will find the image in the attached files
Answer:
Protection
Explanation:
The red arrow seems to be pointing to the membrane of bacteria cells. Probably the green structure also includes the cell wall.
Bacteria are a wide group of unicellular prokaryotic microorganisms with a simple structure and sized between 1 to 10 micrometers. These organisms lack a nucleus, nuclear membrane, and organelles. They only present plasmids and ribosomes. They have a cell membrane and a cell wall that protects the cell. Some of them can also show a capsule.
Membranes and cell walls delimitate and protect the cells from different extracellular factors that might damage them. The membrane constitutes a selectively permeable barrier that allows the free pass of only a few substances while it blocks others.
