Aviolet-flowered, long-stemmed hybrid pea plant was crossed with a true-breeding white-flowered, short-stemmed pea plant with the following offspring:

47 violet, long-stemmed plants, 40 white, long-stemmed plants, 38 violet, short-stemmed plants, 41 white, short-stemmed plants.

if two of the violet, long-stemmed plants above were crossed you would expect to get which of the results listed below?

a. all violet, short-stemmed

b. 1/2 violet, short-stemmed; 1/2 white, short-stemmed

c. 3/4 violet, short-stemmed; 1/4 white, short-stemmed

d. 9/16 violet, long-stemmed plants, 3/16 white, long-stemmed plants, 3/16 violet, short-stemmed plants, 1/16 white, short-stemmed plants

e. they do not all have the same genotype so the expected progeny can not be determined.

In tossing one coin 10 times, what are your chances for tossing a head? a tail? 2. in tossing one coin 100 times, what are your chances for tossing a head? a tail? 3. in tossing one coin 200 times, what are your chances for tossing a head? a tail? deviation = ((absolute value of the difference between expected heads and observed heads) + (absolute value of the difference between expected tails and observed tails)) divided by total number of tosses. this value should always be positive. 4. what is the deviation for 10 tosses? 5. what is the deviation for the 100 tosses? 6. what is the deviation for 200 tosses? 7. how does increasing the total number of coin tosses from 10 to 100 affect the deviation? 8. how does increasing the total number of tosses from 100 to 200 affect the deviation? 9. what two important probability principles were established in this exercise? 10. the percent of occurrence is the obtained results divided by the total tosses and multiplied by 100%. toss the coins 100 times and record your results. calculate the percent occurrence for each combination. percent head-head occurrence: percent tail-tail occurrence: percent head-tail occurrence:

Which of the following is a possible reason for sleep? a) growth b)digestive c)speed d)intelligence

When in solution, a molecule that moves slowly across an artificial membrane moves rapidly across a plasma membrane. this molecule rapidly enters the cell regardless of whether its concentration is higher inside or outside the cell. using this information, which transport mechanism is most likely to be responsible for the movement of the molecule across a plasma membrane? view available hint(s)when in solution, a molecule that moves slowly across an artificial membrane moves rapidly across a plasma membrane. this molecule rapidly enters the cell regardless of whether its concentration is higher inside or outside the cell. using this information, which transport mechanism is most likely to be responsible for the movement of the molecule across a plasma membrane? active transportexocytosis
