Answer:

Sam's average speed  = 2.22 m/s

Explanation:

The average speed refers to the speed with which a distance is covered within a particular time duration. The average speed of a moving object can be obtained by summing up all the varying speeds as the object moves from one point to another, within a particular time frame.

Sams average speed can be calculated using this formula:

Average speed = distance / time

Distance covered = 2000 meters

Time taken to cover the distance = 9:15 am - 9:00 am = 15 minutes = 15 X 60 seconds = 900 seconds

Sam's average speed = 2000meters / 900 secs = 2.22 m/second

The backbone of nucleic acids consists of
V125BC [204]

Answer:

c. a phosphodiester bond between the 3' and 5' hydroxyl groups of neighboring sugars

Explanation:

Phosphodiester bond is the bond which is formed between the hydroxyl group of one nucleotide to the phosphate group of the another nucleotide. These are ester bonds. These bonds are central to all the life which is in existence on Earth. These bonds forms the backbone of the strands of the nucleic acid.

The bond is formed by the linkage of 3' carbon atom of one of the sugar unit to the 5' carbon atom of the another succeeding sugar unit.

<u>Hence, the answer is:- c. a phosphodiester bond between the 3' and 5' hydroxyl groups of neighboring sugars</u>
