ight if we're using the squirrel cage motor as an example, it demonstrates the use of laminations to reduce eddy currents and demonstrates the currents induced in the bars as the magnetic field moves across them. its just easy to elaborate, thus easy marks regardless of the marker.
aight so basically, the dna structure is a double helix or in this case double stranded. in a dna adenine matches with thymine and guanine matches with cytosine to make the "double stranded dna".
so the answer is B
this question is from 2020 hsc bio, it isnt c
from what you have said, and my learning from past paper questions, this is what i would do
so ur data in the zscore formula would look like
62= x-70 / 7
i would just rearrange the formula to ((z-score)x(sd)) + mean)
so now it will look like ((62) x (7)) +70
and that = 504
i might be wrong so idk
