Distance travelled by Bob was 7 meters and the displacement was 5meters.
<h3><u>Explanation:</u></h3>
Distance is defined as the total length of the path travelled by a body from its initial position to final position. Displacement on the other hand is defined as the length of the straight line joining the initial position and the final position of the body.
Here, Bob travelled from point A to point C via point B which took him to travel more distance. The length of distance from point A to B is 4 meters and from point B to C is 3 meters. So the total distance covered is 
meters = 7 meters.
While the length of path straight from point A to C is 5 meters. So displacement is 5 meters.
Answer:
C. A chain of amino acids
Explanation:
Proteins are made up of hundreds or thousands of smaller units called amino acids, which are attached to one another in long chains. There are 20 different types of amino acids that can be combined to make a protein. ... These proteins bind and carry atoms and small molecules within cells and throughout the body.
1) ctg act gct aat (you are correct)
2) GAC UGA CGA UUA
* remember for mRNA, a pairs with u
3) Aspartic Acid (Asp), Arginine (Arg), Leucine (Leu)
4) substitution (t changed to g)
Explanation: from GAC TGA CGA TTA
to GAC GGA CGA TTA
5) new mRNA strand: CUG CCU GCU AAU
6) yes, because the amino acids changed, which will code for different proteins.
Hope that helped! And your teacher did a really bad job forming this question, like how there is no starting codon and (no clarity) you don’t know which DNA sequences to use.
