The correct answer is A. The conservationist credited with founding the Wilderness Society is Bob Marshall.
Bob Marshall was an American forester, botanist, traveler, climber, writer and social activist who advocated the preservation of unspoiled wildlife.
He actively contributed to the development and adoption of environmental regulations prohibiting the construction of roads in vast federal specially protected natural areas. In 1935 he became one of the founders of the public environmental organization The Wilderness Society and its main sponsor.
Today Bob Marshall is considered one of the main initiators of the wildlife movement in the United States. Several geographic features are named after him, including the Bob Marshall Wilderness Nature Reserve in Montana and the Marshall Mountain on the Adirondack Ridge.

Answer:
Explanation:
<u>1) Find the z-scores:</u>
a) z-score for 22.6 inches length
- z = [ 22.6 - 20 ] / 2.6 = 1.00
b) z-score for 17.4 inches length
- z = [ 17.4 - 20 ] / 2.6 = - 1.00
<u>2) Probability</u>
Then, you have to find the probability that the length of an infant is between - 1.00 and 1.00 standards deviations (σ) from the mean (μ).
That is a well known value of 68%, which is part of the 68-95-99.7 empirical rule.
The most exact result is obtained from tables and is 68.26%:
- 1 - P (z ≥ 1.00) - P (z ≤ - 1.00) = 1 - 0.1587 - 0.1587 = 0.6826 = 68.26%

Answer:
Fermentation is a metabolic process in which an organism converts a carbohydrate, such as starch or a sugar, into an alcohol or an acid. For example, yeast performs fermentation to obtain energy by converting sugar into alcohol.
Sometimes bacteria perform fermentation, converting carbohydrates into lactic acid...

Answer:
![T_F=77.4\°C](https://tex.z-dn.net/?f=T_F%3D77.4%5C%C2%B0C)
Explanation:
Hello there!
In this case, according to the given information, it turns out possible to set up the following energy equation for both objects 1 and 2:
![Q_1=-Q_2](https://tex.z-dn.net/?f=Q_1%3D-Q_2)
In terms of mass, specific heat and temperature change is:
![m_1C_1(T_F-T_1)=-m_2C_2(T_F-T_2)](https://tex.z-dn.net/?f=m_1C_1%28T_F-T_1%29%3D-m_2C_2%28T_F-T_2%29)
Now, solve for the final temperature, as follows:
![T_F=\frac{m_1C_1T_1+m_2C_2T_2}{m_1C_1+m_2C_2}](https://tex.z-dn.net/?f=T_F%3D%5Cfrac%7Bm_1C_1T_1%2Bm_2C_2T_2%7D%7Bm_1C_1%2Bm_2C_2%7D)
Then, plug in the masses, specific heat and temperatures to obtain:
![T_F=\frac{760g*0.87\frac{J}{g\°C} *52.2\°C+70.7g*3.071\frac{J}{g\°C}*154\°C}{760g*0.87\frac{J}{g\°C} +70.7g*3.071\frac{J}{g\°C}} \\\\T_F=77.4\°C](https://tex.z-dn.net/?f=T_F%3D%5Cfrac%7B760g%2A0.87%5Cfrac%7BJ%7D%7Bg%5C%C2%B0C%7D%20%2A52.2%5C%C2%B0C%2B70.7g%2A3.071%5Cfrac%7BJ%7D%7Bg%5C%C2%B0C%7D%2A154%5C%C2%B0C%7D%7B760g%2A0.87%5Cfrac%7BJ%7D%7Bg%5C%C2%B0C%7D%20%2B70.7g%2A3.071%5Cfrac%7BJ%7D%7Bg%5C%C2%B0C%7D%7D%20%5C%5C%5C%5CT_F%3D77.4%5C%C2%B0C)
Yet, the values do not seem to have been given correctly in the problem, so it'll be convenient for you to recheck them.
