Answer:

A <u><em>polypeptide</em></u> chain is a sequence of amino acids that is the foundation for the basic structure of a protein.

Explanation:

The amino acids are composed of an organic molecule with an amino group and a carboxyl group. Its combination forms proteins, which are essential for our body. They are formed of carbon, oxygen, hydrogen and nitrogen. Among its functions, amino acids help break down food and repair body tissues.

Proteins consist of one or more amino acid chains; These chains are called polypeptides. These are peptides when the chains are composed of at least ten amino acids. Then a polypeptide, in other words, is a sequence of amino acids that are linked through peptide bonds. If the chained amino acids are more than a hundred, then we talk about protein. Proteins, therefore, are made of polypeptide chains.

Generally a polypeptide contains between 50 and 100 amino acids.

So:

<u><em>A polypeptide chain is a sequence of amino acids that is the foundation for the basic structure of a protein.</em></u>

A basketball has a mass of 609 g. Moving to the right and heading downward at an angle of 32° to the vertical, it hits the floor

andrezito [222]

Answer:1.549 kg-m/s

Explanation:

Given

mass of basketball =609 g

ball is moving downward right at an angle of $32 ^{\circ}$ with vertical

After hitting the floor it moves with a speed of 3 m/s

change in Momentum in x direction

$P_x=musin32\hat{i} -mvsin32\hat{i}$

where u=3m/s

v=3m/s

m=mass of ball

$P_x=0$

Change in momentum in Y-direction

$P_y=-mucos32\hat{j}-mvcos32\hat{j}=-2mvcos32$

$P_y=-1.549\hat{j} kg-m/s$

A special standard weight, known to weight 10 N to high accuracy, is used to check the accuracy of two spring scales. On the fir

zysi [14]

Answer:

16 % and 9 %

Explanation:

Accurate reading = 10 N

reading of first balance = 8.4 N

reading of second balance = 9.1 N

Percentage difference in first reading

= $\frac{True reading - reading of first balance}{True reading}\times 100 %$

= $\frac{10-8.4}{10}\times 100 %$ = 16 %

Percentage difference in second reading

= $\frac{True reading - reading of second balance}{True reading}\times 100 %$

= $\frac{10-9.1}{10}\times 100 %$ = 9 %

a motorboat is headed at a velocity of 25 kilometers/hour toward the north, while the velocity of the water current is 12 kilome

fiasKO [112]

The magnitude of the boat's resultant velocity will be 13 kilometers/hour.

<h3>What is velocity?</h3>

The change of distance with respect to time is defined as speed. Speed is a scalar quantity. It is a time-based component. Its unit is kilometers/hour.

The magnitude of the boat's resultant velocity is found as;

$\rm V_{resultant}=V_{north}-v_{west} \\\\ \rm V_{resultant}= 26 km/h - 12 km/h \\\\ V_{resultant}=13 \ km/h$

Hence, the magnitude of the boat's resultant velocity will be 13 kilometers/hour.
