Beta ( β ) sheets are a type of secondary structure in proteins. A segment of a single chain in an antiparallel β sheet has a length of 193 Å . How many residues are in this segment?

55 residues

Step-by-step explanation:

We are given that length of sheet= 193 Å

We need to find out the number of residues in this segment.

Now in an anti parallel  β sheet, the repeat comes out after every 7Å.

In every repeat, there are 2 residues.

So, to find out the number of residues in segment, we multiply the number of segments with the residues in every segment.

Residues in segment=

Residues in segment= 55.14

Or 55 residues.

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

13

step-by-step explanation:

divide the cost of the total of sodas you bought by the cost of one soda, for example:

$24.57 divided by $1.89 is 13 which means you bought 13 sodas
