When an auditor is concerned about the omission of an account payable which of the following assertions do they need to collect evidence for?

Which of the following is the correct order from most broad to most specific?

A financial statement audit is designed to:

The ability to roll your tongue is a dominant trait (R = tongue rolling allele, r = non-rolling allele).  If Gina is able to roll her tongue, but her father is not, what is Gina’s genotype?  

Assume you are trying to replicate the findings of Mendel by conducting a series of studies on his beloved pea plants.  Flower color and flower position are characters found on different chromosomes in the pea plant genome (thus they sort independently of one another).     Character Dominant Trait  Recessive Trait Flower Color Purple (P) White (p) Flower Position Axial (A) Terminal (a)   If a plant that is heterozygous for both characters is allowed to self-fertilize (PpAa x PpAa), what proportion of the offspring would you expect to be as follows?  NOTE: The same answer can be used on multiple problems.   A.  Heterozygous for both characters? B.  Homozygous dominant for both characters? C.  Terminal and white? D.  Purple and axial?

If you have a dihybrid cross of a pea plant for the following two traits: R = round, r = wrinkles (Round (R) is completely dominant over wrinkled (r)), and V = violet flowers, v = white flowers (Violet is completely dominant over white). What is the probability of getting a plant with Round peas and white flowers from the following cross:   RrVv  x   rrVv    

BONUS QUESTION:  Up to 4 EC pts. Many photosynthetic organisms carry out a process known as cyclic electron flow (also known as cyclic photophosphorylation). Given your knowledge about the Calvin cycle and about what happens in cyclic electron flow, explain: Be sure to answer both parts (a and b) and start your answer with an indication of which part you are answering.    (a) why it is beneficial for the plant to undergo this alternative route in electron transfer  (2 pts), (b) Why can’t the cell continuously use this cyclic mechanism of photosynthesis in order to always conserve water? In otherwords, why must all plants do linear photosynthesis sometimes?  (2 pts)
