Answer: lung
Step-by-step explanation:
Attachedfile/picture shows the structure.
Respiration is a process of degradation of complex organic compound with the production of carbon dioxide, water and energy.
Respiration involves two phases, which are;
(1). External Respiration or Breathing: this is a process in which
animals take oxygen in and release carbon dioxide.
(2). Internal Respiration or Cellular Respiration: this process involve the release of energy from food substance with the release of carbondioxide and and water.
Single celled animals or unicellular animals such as amoeba exchange gases through cell surface. The STRUCTURE X IS THE PLASMA MEMBRANE. There is absorption of of Oxygen from the surrounding air or water,hence, giving out carbondioxide through plasma membrane by Diffusion.
PS: Lung is used in respiration process in Human
With the frequecy distribution shown in the 50 cities of pakistan,
- range = 18
- mean = 18.1
- median = 19.8333
- mode = 19.125
- kurtosis = 2.7508
- Standard deviation = 3.75
= highest value - lowest value
= 26.5 - 8.5
= 18
<h3>How to find the mean</h3>= ∑ f x / ∑ f
= ∑ f x / N
= 905 / 50
= 18.1
median
= lower limit + ( N/2 - C ) * h / ( frequency of the class interval )
C = cumulative frequency preceeding to the median class frequency
h = class interval
= 18.5 + ( 50 / 2 - ( 5 + 12 ) ) * 3 / 18
= 18.5 + 1.3333
= 19.8333
<h3>How to find the mode</h3>The mode is the value with the highest frequency occurence. This is under class 18 - 20
mode = lower limit + ( ( f1 - f0 ) / (2*f1 - f0 - f2 ) ) * h
f1 = fequency of the modal class
f0 = freqency of the preceeding modal class
f2 = frequency of the next modal class
h = class interval
= 18.5 + ( ( 18 - 12 ) / (2 * 18 - 12 - 8 ) ) * 3
= 18 + ( 0.375 ) * 3
= 19.125
<h3>How to find the standard deviation </h3>= sqrt ( 1 / N ∑ f ( x - x' )^2 )
= sqrt (1 / 50 * 706.5
= 3.7589
<h3>How to solve for relative dispersion </h3>= standard deviation / mean
= 3.7589 / 3
= 1.2530
<h3>What is the variance? </h3>= ( standard deviation )^2
= ( 3.7589 )^2
= 14.1293
<h3>How to solve for kurtosis</h3>= ∑ f ( x - x' )^4 / ( N * ( standard deviation )^4 )
= 27459.405 / ( 50 * 3.7589^4 )
= 2.7509
