How much energy is available at the secondary level?

Sidana [21]

<h3>Answer: <u><em>Hope this helps </em></u></h3><h3><u><em /></u></h3><h3>Explanation: </h3><h3><u><em>This pattern of energy transfer continues with each successive level of the pyramid. Secondary consumers receive 10% of the energy available at the primary consumer level (1% of the original energy). Tertiary consumers receive 10% of the energy available at the secondary level (0.1% of the original energy).</em></u></h3><h3><u><em /></u></h3>

A student designed an experiment to determine if air temperature had an effect on the rate of photosynthesis in corn plants. Whi

Gnom [1K]

The provided question was incomplete as it lacks the options. However, the correct option for this question is as follows:

an electronic balance to measure the volume of soil in which each corn plant is grown

a graduated cylinder to measure 30 mL of water for each plant daily

a metric ruler to determine the mass of each plant each week

a Celsius thermometer to determine the pH of the soil

Answer:

The correct answer is - a graduated cylinder to measure 30 mL of water for each plant daily

Explanation:

The basic knowledge requires to answer this question, as it is not asking about the photosynthesis or temperature of the air but the tool which is correctly matched, so let's get the answer from the options:

the first option is talking about the electric balance and measuring the volume of soil with it, as wee know electric balance measures mass or force on the pan downwards which is the mass of the substance. so it is an incorrect match.

Graduated cylinder to measure the 30 ml water which is correct as this tool measure volume of liquid or substance.

A metric scale measures distance or length of an object, not the mass thus, it is an incorrect match.

A thermometer measures the temperature, not the pH of a substance so it is also an incorrect match.

I don't think the answer is A as that seems a bit drastic, I think it's C.

An acidic solution of pH 5 has<br> TIMES as many hydrogen ions (H+) as does a solution of pH 6.

Artyom0805 [142]

The difference in concentration of hydrogen Ions between pH5 and pH6 is - x 10.

The pH scale is a scale or measure to find the strength of acidity or the basic nature of a solution or substance. pH 1 is acidic and pH 14 is the most basic on the scale.

The concentration of hydrogen ions is inversely related to its pH
More hydrogen ions present, the lower the pH
The fewer hydrogen ions, the higher the pH We know,

pH = -log(H+) then,

=> 5 = -log (H+)

=> H+ = $10^{-5}$ (for pH = 5)

=> pH = -log(H+)

=> 6 = -log (H+)

=> H+ = $10^{-6}$ (for pH = 6)

Thus, The substance with the lower pH (5) has 10 times as many hydrogen ions per volume of water.
