Answer:
The difference in pH caused the genes for flower color to be expressed differently
Explanation:
Twenty cuttings were taken from one plant and planted in four containers of sand. two containers had a ph of 6.0, and two had a ph of 8.0. when the cuttings matured, all of those grown in a ph of 6.0 had pink flowers, and all of those grown in a ph of 8.0 had blue flowers. one explanation for these results is that the sand at one ph contained a dye that changed the flower color. the best alternative explanation for these results is that difference in pH caused the genes for flower color to be expressed differently
Answer and Explanation:
These lights can, in fact, promote the growth and reproduction of plants.
This is because growth, chlorophyll production, flowering and fruiting only occur if the plant is exposed to a band of light with 640-720 nm. Plants receive this band of light naturally through the sun, but when solar energy is not available it is possible to use cultivation lamps that emit this type of light band, which corresponds to the yellow/red spectra.
Answer: Yes and no. You can use a lemon as a battery to generate electricity, but you cannot "make" electricity out of a lemon.
Explanation: Lemons have citric acid, and acids typically are very grateful and open to receiving electrons. So, if you have good conductors like copper and zinc, the acid will react with the zinc and loosen the electrons allowing them to move towards the copper.
TA-DA. You've just created a battery (a rather weak one) out of a lemon.
I feel like this is more of a chemistry question rather than a biology one, but nevertheless, I hope this helped.
Answer:
False
Explanation:
There are some health issues that make you not able to leave the house. So therefore you can't have a social life.
