Trait | Dominant | Recessive |
Pea Shape | Smooth (S) | Wrinkled (s) |
Pea Color | Yellow (Y) | Green (y) |

1. You cross two pea plants to create F1 progeny that are heterozygous for all 5 traits.
a. What is the probability of one F1 plant generating a gamete with alleles for green peas that are wrinkled OR smooth?
b. If you now cross two F1 plants, what proportion of offspring would have smooth, yellow peas with constricted pods, terminal flowers, and dwarf stems?
c. From this same cross, what proportion of offspring would have smooth, green peas with inflated pods, axial flowers and dwarf stems?

1. "Dr. Meyer wants to study the effect of Kava root on insomnia. She recruits 150 people who experience long term insomnia (more than 4 months experiencing insomnia) and divides them into two groups. One group of 75 individuals takes 125 mg of kavalactones one hour before bedtime. The other group of 75 individuals takes a placebo every day. For the duration of the study, the two groups follow two common guidelines: no added sugars or caffeine intake after 12pm and no screen time an hour before bedtime. Dr. Meyer follows the individuals during four weeks. She collects data on sleep patterns which include the number of hours slept each night and a scale of difficulty to fall asleep scored 1 to 5 (1 = feel asleep right away; 5 = more than one hour awake in bed)."
Answer Following:
What is the independent variable?
What is the dependent variable?
What is the experimental group?
Which is/are Dr. Meyer’s controlled variable(s)?
2. "“If Vitamin C supplementation shortens the length of the common cold, then adults taking 1g of Vitamin C a day will recover from the common cold faster than adults who aren’t taking Vitamin C supplementation.”

A plant is placed in a sealed box with sufficient air, water and sunlight for several months. A chemical is added to the chamber that immediately adds electrons to all the oxygen in the chamber. Assume plants cannot perform fermentation. Also remember that gas diffuses freely across membranes and cell walls.
Which of the following is most likely if the plant is left in the chamber
the plant will die because it will be unable to do respiration |
the plant will die because it can no longer perform the light reactions |
the plant will die because it will not be able to go through the Calvin cycle |
the plant will live because it can perform glycolysis |
the plant will live because it does not require oxygen fo rmetabolism |

It is well known that sugars glucose and fructose are the primary fermentable substrates. However, malic acid can also be fermented but to lactic acid rather than ethanol. This is especially important in red wine, why?

gravis vs. guillain-barré syndrome what’s the
difference? (Links to an external site.)Links to an external
site. Nursing Made Incredibly Easy! 12 (4). 21-30.
Initial Discussion Post:
Select one (1) of the following Nursing Diagnoses:
Impaired Spontaneous Ventilation
Impaired Swallowing
Care Giver Role Strain
Address the following:
Is the nursing diagnoses that you selected appropriate
for the patient with a diagnosis of myasthenia gravis,
Guillain-Barre syndrome or both? Explain your answer.
Provide an outcome for the nursing diagnosis that you selected
making sure that is specific to the needs of the patient with
myasthenia gravis or Guillain-Barre syndrome.
Identify two (2) interventions that will help your patient with
myasthenia gravis or Guillain-Barre syndrome reach the outcome for
the nursing diagnosis.

Based on what you know about transcription, RNA processing, and translation, how can a single sequence variant have different effects on the amino acid sequence across the transcript variants of a gene? How can a single sequence variant appear in different amino acid positions in the polypeptides translated from transcript variants of a single gene?

Having identified each of these cDNAs, you want to determine the intracellular route traveled by each of these glycoproteins, and the speed with which they traverse their biosynthetic pathways to arrive at their final destination. How would you use a pulse-chase experiment in combination with monitoring the glycosylation status of your glycoproteins to determine the speed with which these proteins traverse their biosynthetic pathway?
