Darwin’s most important observations were made on the Galapagos Islands. This is a group of 16 small volcanic islands situated off the west coast of Ecuador, South America.

Darwin observed that organisms on the Galapagos were similar to, yet different from, one another and from similar species in South America. For example, the giant tortoises on one island had saddle-shaped shells, while those on another island had dome-shaped shells. People who lived on the islands could even tell the island a turtle came from by its shell. This started Darwin thinking about the origin of species. He wondered how each island came to have its own type of tortoise.

Based on the data table below, which number would be the BEST choice for the top number of the scale on the vertical axis of a s

sdas [7]

Answer:

D. 70

Explanation:

From the table given, we can easily tell that distance (m) is dependent on time (s). Distance is a dependent variable, while time is an independent variable.

If both variables were to be plotted to show the relationship between them on a scatter plot, the dependent variable is usually plotted on the vertical axis (y-axis), while the independent variable would be plotted on the horizontal axis (x-axis).

Distance would be in the vertical axis, while time would be in the horizontal axis.

Therefore, the BEST choice for the top number of the scale on the vertical axis would certainly be 70, because the highest value for distance (m) on the table of values is 69.

What can or should be done when populations are disproportionately unhealthy or at higher risk for certain health conditions? pr

KonstantinChe [14]

The following are some of the main reasons that patients have a poor outcome or at higher risk for certain diseases and suggested solutions.

- Genetic factors: Can’t be modulated

- Less access to health care providers because of far distance for example: First identify these neighborhoods and send mobile clinic that meets their need on regular bases.

- Greater exposure to environmental toxins: Raise the awareness of the citizens of the commonly known toxins in their area in commercial ads in TV, newspaper, and radio. There should be a routine inspections form the department of environmental health (DEH) in neighborhoods that are known to rodents/bugs infestation. This will offer help to the citizens and increase their awareness.

- Unhealthy lifestyle: Commercial ads will encourage healthy eating. Make healthy meal options readily available at lower cost.

For example, the percentage of kidney dialysis in the United States is considerably higher in poor areas. According to the American Cancer Society, the rate of colon cancer is much higher in the following regions compared to the rest of the country; North Carolina, west-central Appalachia and in the Mississippi delta.
