Answer:
Take two potted plants and provide equal conditions to both.
Explanation:
Two potted plants i.e. one is placed near the nuclear accident site while on the other hand, the other is placed far away from the nuclear accident. Provide equal conditions to both plants so that we can find out the hypothesis that the frequency of mutations decreases with the organisms distance from the source of radiation. The result shows that the potted plant that is located near to the nuclear accident site having high frequency of mutation as compared to other plant due to the radiation present at that location.
<span>keeping their stomata open just enough to allow photosynthesis to take place but not so much that they lose an excessive amount of water. Leaves take in carbon dioxide and give off oxygen during photosynthesis.</span>
=3x14 - 13x2 + 4
Apply the FOIL method: (a+b)(c+d) = ac+ad+bc+bd
Which will look like this:
(3x2 x2 + 3x2 (-4) -1 TIMES x2 -1 TIMES (-4)
And then simplify
Answer:
light enters a plant through its leaves O2 enters the plant through the stomata's or open pores
and water enters through the roots then up the stem to the tubes to leave
