b. In 1979, the estimated elephant population was 1.3 million and in 2007 it was 640,000. By approximately what percentage did t

saveliy_v [14]

Answer:

The initial amount, 1.3 million = 1,300,000 is the 100%.

now, 640,000 is a given percentage (lower than 100%) of that.

How we can find it?

suppose that 640,000 represents an x%.

Then we have that the quotient between the actual quantities and the percentages must be the same

(640,000/1,300,000) = x%/100%

x% = (640,000/1,300,000)*100% = 49.23%

Then the percentage declined is:

100% - 49.23% = 50.77%

The other question can not be answered with the given information.

Answer:

Pressure with Height: pressure decreases with increasing altitude. The pressure at any level in the atmosphere may be interpreted as the total weight of the air above a unit area at any elevation. At higher elevations, there are fewer air molecules above a given surface than a similar surface at lower levels.In addition, gravity is weaker at the equator due to centrifugal forces produced by the planet's rotation. It's also weaker at higher altitudes, further from Earth's centre, such as at the summit of Mount Everest

If a closed container contains a mouse as well as enough food, water, and oxygen for the mouse to live for three weeks, how much

ale4655 [162]

Answer:

The life process may be defined as the different process that are important for the sustenance of life. The most important life process are nutrition, respiration, excretion and transportation.

If the mouse is placed in the closed sealed container then the weight will remain before and after the experiment of 1 or 2 week. This is because the life process metabolic reactions will use and conserve all the atoms involved in the life process. These atoms can exist in the liquid, solid and gas forms but present inside the container.

Acidity in human sweat is an example of _____. Acidity in human sweat is an example of _____. acquired immunity adaptive immunit

Tpy6a [65]

Acidity in human sweat is an example of<u> </u><u>innate immunity</u>

Explanation:

Sweat arising from human skin is acidic in nature with a pH ranging between 4.5 to 7.

As part of innate immunity, the skin acts both as a physical barrier and chemical shield.

As part of chemical shield, the skin’s sebaceous glands present on the skin produces an oily substance called sebum which contains free fatty acids. Further, hair follicles on skin releases lactic acid which bind with the amino acids of the proteins present on the keratinized layers of skin. The acidity of the sweat is due to the combined action of free fatty acids, lactic acid and the amino acids present on the skin.

This natural acidic nature of skin creates a hostile acidic environment to pathogens which prevents their entry into the body.
