Calculate the volume change for respiration in the dark. As you already saw from earlier questions, oxygen production is fairly
Tatiana [17]

Answer:

-1.9mL/min

Explanation:

The rate of O₂ production can be calculated by the formula

= ( Final volume - initial volume)/time(min).

From the graph provided and attached below, the rate of O₂ production or rate of photosynthesis at light intensity of 8 is about 3.75 mL/min.  

The rate of O₂ production is taken as the rate of photosynthesis. It is expected to progressively increase from light intensity 0 as light intensity increases. However, at very high light intensity, the rate slows down as water becomes limiting and the stomata closes in order to conserve water.

Question in order

Experiment 2: Respiration in the Dark

Calculate the volume change for respiration in the dark. As you already saw from earlier questions,

oxygen production is fairly constant. You will not need to calculate the individual volume changes.

Just subtract the original volume at 00:00:00 from the final reading at 00:02:00. Record your answer

for use in a later question.

<em>Note: depending on when you started the timer there is a range of possible answers. Pick the answer that is closest to this</em>

What was the volume change for respiration in the dark?

Correct answer:

-1.9 mL/min

What is the difference between climate change and climate variability ​
vaieri [72.5K]

Answer:

Climate change is the change of temperature in the worlds climate system and climate variability is the variations in a certain climate that last longer then  certain weather events.

Explanation:

To explain more climate change is the change in the daily weather in a area for example rain forest to desert or cold to hot climate change goes along with global warming which is the heating of our Earth which causes ice to melt in the arctic rising our sea levels creating stronger storms. While in a climate variability its only a certain time of that specific climate change for example its only cold for a certain period of time then the temperature rises to hot again. So, the key difference is that "climate change is the change of temperature in the worlds climate system and climate variability is the variations in a certain climate that last longer then  certain weather events."

When a plant dies, most of the nitrogen in the plant's tissues is:​
Lubov Fominskaja [6]

Answer:

The Nitrogen Returns into the Soil (Nitrogen Cycle)

Explanation:

After a plant dies it's the job of a decomposer to carry along the nitrogen back to the surface so that it may continue to cycle along, until it eventually returns back to the decomposer through the death of another plant. This part of the cycle is small compared to the whole Nitrogen cycle.
