Answer:
Stomata - specialized cells that contract and expand to open or close pores for gas exchange. Stomata can adjust to temperature, staying closed when temperatures are hot and dry to prevent gas and water loss.
Explanation:
Stomata (singular stoma) are pores found in the epidermis of plant leaves. Stomata open and close in response to the change in structure of two guard cells either side of the pore opening. When the guard cells are turgid, the stomata open, when they are flaccid, they are closed.
This functions to permit gas exchange while preventing the loss of water, especially during hot, dry weather. The stomata can only open when the guard cells are turgid, pulling the stomata apart.
Hi there!
This would be an example of an energy pyramid! In an energy pyramid, the next trophic level gets only 10% of the energy from the level below it. In this example, lets say that there is 100 energy in the eggs. Then, 10% of that goes to the snake, so the snake gets 10. Lastly, the hawk eats the snake, so the hawk gets 1. The answer is 1%, option A.
Hope this helps!! :)
If there is anything else that I can help you with, please let me know!
The given values are 14,000 sample size and 5% p-value. Statistical significant results are achieved when p-value is less than the significance level. This shows a 95% confidence of results in the samples. The rejection region is composed of 5% of the sample distribution.
This should be correct, but it is not a 100% guarantee on my part.
1. Moles Fe = 209.7 g/ 55.847 g/mol= 3.75
The ratio between Fe and CO is 2 : 3
Moles CO = 3.75 x 3 /2 = 5.63
<span>Mass CO = 5.63 mol x 28.01 g/mol= 157.7 g
2. </span><span />2Na + 2H2O --> 2NaOH + H2<span>atomic weight of sodium is 23 48.7/23 = 2.12 moles of sodium
2.12/2 x 24 = 25.44dm^3 hydrogen = 1.06 moles
so multiply it by Avogadro's number1.06 X 6.02x10^23 = 1.204x10^24 molecules of hydrogen
