Question:

Which statement best​ explains how Sarah Zielinski introduces and develops her points in the article about​ Henrietta Lacks?

  1. Zielinski explains how her interest in the Henrietta Lacks story began then provides details about the first  immortal human tissue sample and tells why it has been both important and controversial.
  2. Zielinski explains the need for using human tissue samples then introduces Rebecca Skloot who gives an  account of her experiences of researching the origin of the HeLa cells.
  3. Zielinski explains how the first immortal human cells were found then provides Rebecca Skloot’s answers to  questions about the importance of using human tissue samples, the Lacks family’s responses to learning of its  link to the HeLa cells, and the issues arising from their discovery and use.
  4. Zielinski explains the importance of the first human tissue samples to life and their widespread use, the  reason for the confusion about those samples as well as the ethical issues faced by the Lacks family after learning they had not shared in profits from the sale of the HeLa samples.

Answer:

The correct answer is number 3

Explanation

The article devotes the first three sentences to describing how the Immortal cells came to be. In sentence 4, she makes reference to a book by Rebecca Skloot titled <em>The Immortal Life of Henrietta Lacks. </em>The book explains the history of Henrietta's cells and its impact on Henrietta's family as the medical world.

A manufacturer makes two types of drinking straws: one with a square cross-sectional shape, and the other type the typical round
Harlamova29_29 [7]

Answer:

\frac{Q_{square}}{Q_{circle}} =  0.785  

Explanation:

given data

types of drinking straws

  1. square cross-sectional shape
  2. round shape

solution

we know that both perimeter of the cross section are equal

so we can say that

perimeter of square  = perimeter of circle  

4 × S = π × D

here S is length and D is diameter

S = \frac{\pi D}{4}        ....................1

and

ratio of  flow rate through the square and circle is here

\frac{Q_{square}}{Q_{circle}} = \frac{AV^2}{AV^2}  

\frac{Q_{square}}{Q_{circle}} = \frac{S^2}{\frac{\pi D^2}{4}}  

\frac{Q_{square}}{Q_{circle}} = \frac{(\frac{\pi D}{4})^2}{\frac{\pi D^2}{4}}  

\frac{Q_{square}}{Q_{circle}} = \frac{\pi }{4}  

\frac{Q_{square}}{Q_{circle}} =  0.785

The stagnation chamber of a wind tunnel is connected to a high-pressure airbottle farm which is outside the laboratory building.
Natasha2012 [34]

This question is not complete, the complete question is;

The stagnation chamber of a wind tunnel is connected to a high-pressure air bottle farm which is outside the laboratory building. The two are connected by a long pipe of 4-in inside diameter. If the static pressure ratio between the bottle farm and the stagnation chamber is 10, and the bottle-farm static pressure is 100 atm, how long can the pipe be without choking? Assume adiabatic, subsonic, one-dimensional flow with a friction coefficient of 0.005

Answer:

the length of the pipe is 11583 in or 965.25 ft

Explanation:

Given the data in the question;

Static pressure ratio; p1/p2 = 10

friction coefficient f = 0.005

diameter of pipe, D =4 inch

first we obtain the value from FANN0 FLOW TABLE for pressure ratio of ( p1/p2 = 10 )so

4fL_{max} / D = 57.915

we substitute

(4×0.005×L_{max}) / 4  = 57.915

0.005L_{max} = 57.915

L_{max} = 57.915 / 0.005

L_{max}  = 11583 in

Therefore, the length of the pipe is 11583 in or 965.25 ft

What is the magnetic force on a moving electric charge called
crimeas [40]
The magnetic force on a free moving charge is perpendicular to both the velocity of the charge and the magnetic field with direction given by the right hand rule. The force is given by the charge times the vector product of velocity and magnetic field.
