Answer:

1- The amount of time passed in hours before getting a sunburn.

2- 30 minutes, 1 hour 30 minutes, 5 hours

3- SPF 15 so that person C won't get a sunburn until after 15 hours.

4- SPF 15 is more effective because when you add the time passed until you got a sunburn with SPF 4 and compared that to what you got when adding up the data from using SPF 15, you can see that it is more effective.

5- The number in the SPF rating stands for about how much time an average person can go without getting sunburned.

Hope this helps!

Transposable elements make up 44% of the human genome. What is thought to be their function?
AfilCa [17]

Transposable elements are considered to be responsible for vast range of genome diversity and gene silencing.

Explanation:

Transposable elements are short sequences of DNA that have the ability to move from one location to another in the genome. During this process they copy themselves.

The entire process carried out by transposable elements to copy themselves and move from one location to another is called transposition.

Transposition may result in mutation and is potentially a major source of genome diversity and change. If a transposon inserts itself into the coding region of a gene,it interrupts the coding sequence and inactivates the gene expression.

In addition to this, a transposable element may contain transcription or translation termination signal that will block the gene expression downstream of insertion site.
