If a portion of a strand of DNA bases reads 5' AGCTAGCGT 3', what would the sequence of bases on the complementary strand read?
3' TCGATCGCA 5'
3' TCGUTCGCU 5'
3' AGCTAGCGT 5'
5' SucGAUCGCA 3'
The Correct Answer is A
The sequence of bases on the complementary strand of DNA would read 5' TCGATCGCA 3'. In DNA, the nitrogenous bases adenine (A) and thymine (T) pair together, and cytosine (C) and guanine (G) pair together. The complementary strand is also antiparallel to the original strand, meaning that it runs in the opposite direction with the 5' end matching up with the 3' end of the original strand. The other options do not accurately represent the complementary sequence of bases or the antiparallel orientation of the strands.

. Atoms, cells, tissues, organs. This is the correct order of structures from simple to complex. Atoms are the smallest and simplest units of matter. Cells are made up of atoms and are the basic units of life.
Tissues are groups of similar cells that work together to perform a specific function. Organs are made up of different types of tissues and perform more complex functions.
A. Cells, tissues, atoms, and organs is not in the correct order from simple to complex.
B. Atoms, organs, tissues, cells is not the correct order from simple to complex.
d. Organs, tissues, cells, atoms is not the correct order from simple to complex.
Correct Answer is C
Explanation
Data are biased by the methodology. The researcher's data should be rejected because they are biased by the methodology used to gather them. By only using a small net, the researcher excluded all large birds from the study. This means that the data do not accurately represent the average wing strength of all birds found in the American Northwest.
A. The data contradicting the control group is not a reason to reject the data in this case.
B. The data being different than expected is not a reason to reject the data in this case.
D. The data not being able to be displayed graphically is not a reason to reject the data in this case.
