Construct the sequence of events leading from a dietary vitamin C deficiency to symptoms such as bruising and breakdown of supporting tissues. Rank the events from the first to the last.
collagen breaks down
enzyme prolyl hydroxylase is inactive
the triple helix is inadequately stabilized
defects in tissues that depend on collagen
proline is not hydroxylated
tissue levels of ascorbic acid is low
tissues that depend on collagen are subject to breakdown and bruise.
First Last

The question is not complete. Here is the full question:

Construct the sequence of events leading from a dietary vitamin C deficiency to symptoms such as bruising and breakdown of supporting tissues. Rank the events from first to last.

- enzyme prolyl hydroxylase is inactive

- the triple helix is inadequately stabilized

- tissues that depend on collagen are subject to breakdown and bruising

- tissue levels of ascorbic acid is low

- collagen breaks down

- defects in tissues that depend on collagen

- proline is not hydroxylated

Explanation:

Here is the right sequence of events:

"do a testcross with a homozygous recessive plant."

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
