Read the sentence. i have tried many times to get a job. what is the verb tense of the phrase in bold? future present perfect present past

The answer is past for me because it is not saying that you ARE going to try and it is not present because it didn't say "i am trying to get a job".

I believe it's past hope this helps :)

Where is the excerpt? it’s not attached

Okay, biology isn't exactly my strongest subject (it never has been), but i'm pretty sure the answer is nucleotides. dna is made up of nucleotides. each nucleotide contains a phosphate group, a sugar group, and a nitrogen base. there are four different nitrogen bases: adenine (a), thymine (t), guanine (g), and cytosine (c). a always pairs with t, and g always pairs with c.
