Did the direction the seed was facing change how the roots and stems grew? Include in your answer how the growth looked for each of the four seeds. Plants do not have any sensory organs so how do the stems of a plant know to grow up toward the light and the roots of a plant to grow down toward the water?
Describe how the roots looked in comparison to the stems; include color and any other characteristics you could see.
Plants may not be motile but they are capable of movement. Research phototropism and geotropism, how are they different and how are they the same?

Apopulation has 1000 individuals. over a period of 1 year, 500 newindividuals are born. which equation shows how to calculate the birthrate ofthis population? a. 500 - 1000 = 0.5b. 1000 x 0.5 = 500c. 1000 - 500 = 2d. 1000 + 500 = 1500

6. in domesticated cats, the following are independently assorting: normal ears (t) is dominant to tufted ears (t); curved whiskers (c) is dominant to straight whiskers (c); the presence of six toes (s) is dominant to five toes (s); gene for hair length is an x-linked codominant. the three phenotypes for hair length are long (xhxh), medium (xhxh), and short (xhxh); medium is the heterozygous condition. given two parents: ttccssxhxh x ttccssxhy how many different gametes could be formed in the female cat with respect to these four traits? how many phenotypes are possible in the offspring from this mating?
