Synthetic compounds found in an organism but not normally produced or expected to be present in that organism are called _____.
nlexa [21]

The correct answer is D. Xenobiotics

Explanation:

In biology, the word "xenobiotics" refers to any substance or chemical compound that is considered as not natural or synthetic is an organism, this means the substance or compound is not produced by the organism and therefore it is not expected to be found on it. In the seam way, a substance that is natural to the organism but that is found in abnormal concentration might be considered as a xenobiotics. This concept differs from pesticides because these are substances used to control pests and from bio remediators because these are used to deal with contamination. Therefore, the word that describes synthetic compounds that are not produced or expected to be present in an organism is xenobiotics.

You measure the pH of your backyard soil and find it is 7. You measure the pH of your friend's backyard soil and find it is 4. H
olchik [2.2K]

Answer:

1000 times.

Explanation:

Hello,

In this case, since the pH is defined by:

pH=-log([H^+])

If we want to compute the concentration of hydrogen we must write:

[H^+]=10^{-pH}

Thus, for both the backyard soils we compute:

[H^+]_{pH=7}=10^{-7}=1x10^{-7}M

[H^+]_{pH=4}=10^{-4}=1x10^{-4}M

It means that:

\frac{[H^+]_{pH=4}}{[H^+]_{pH=7}} =\frac{1x10^{-4}M}{1x10^{-7}M}\\ \\\frac{[H^+]_{pH=4}}{[H^+]_{pH=7}}=1000

It means that the concentration of hydrogen at a pH of 4 is 1000 times greater than the concentration of hydrogen at a pH of 7.

Regards.

Rhonda Runsalot is a 20 year old woman. She is running at VO2max. Her heart rate is 200 b/min. Her stroke volume is 100 ml blood
katen-ka-za [31]

Answer:

Cardiac output = 20 L/min

Explanation:

The cardiac output of a person refers to the volume of blood the heart pumps in a minute. The normal range for cardiac output is about 4 to 8 L/min. However, this can vary depending on the metabolic needs of the individual at any instant of time, for example, it is higher when exercising than  when resting.

Cardiac output is calculated from the product of the stroke volume in liters/min and the heart rate in beats/min

Cardiac output  = stroke volume * heart rate

For the individual who is running; stroke volume = 100 mL/beat or 0.1 L/beat

heart rate = 200 beats/min

Cardiac output =0.1 L/beat * 200 beats/min

Cardiac output = 20 L/min
