It also reabsorbs water found in the undigested food
Answer:
The kidneys take of up more Ca2+ and release vitamin D. The bones release Ca2+. The intestines increase reabsorption of Ca2+.
Answer:
What occurs when too much of a population rely on something?
This leads to overcrowding after which competition sets in and it would diminish the resources and death of the unfit organism while the fittest survives.
Explanation:
Answer:
You can use an iodine solution to detect the presence of complex carbohydrates.
Explanation:
The yellow-orange iodine will turn blue-black as it reacts with starch. (The iodine solution will show no reaction with simple carbohydrates or sugars.)
The rate of volume change can be used to find out how different lights (different wavelengths) affect photosynthesis and plant growth. To calculate it, we just need to record data of volume change and time.
------------------------------------------------------
To determine the rate of volume change, you need to use the following formula.
Rate of volume change (mL/hr) = <u>Final volume</u><u> - </u><u>Initial volume </u><u> </u> x 60
Time

To calculate the rate of volume, we will use the following data.
If these values are different from yours, you just need to replace them acoording to the data in your table.
<u> Time (min) White light volume </u>
0 3
5 4.3
10 5.6
15 6.9
<u> 20 8.2 </u>
So, according to these values
- Final volume, Vf = 8.2 mL
- Initial volume, Vi = 3 mL
- Time, T = 20 min
Rate of volume (mL/hr) = ((Vf - Vi)/ T) 60



The rate of volume change for Elodea in white light is 15.6 mL/hr.
