During exhalation, your respiratory muscles contract to push air out of your lungs.
Your respiratory muscles contract each time you exhale.
When you exhale, the primary muscle responsible for this action is the diaphragm, which contracts and moves upwards, reducing the volume of the lungs and forcing air out. Additionally, the intercostal muscles, located between the ribs, also contract and help in the process of exhalation.
In summary, your respiratory muscles contract during exhalation to push air out of your lungs.

B. 1/2
C. 1/256
D. 81/256
E. 9/256
Answer:
C. 1/256
Explanation:
In the tetrahybrid cross, we have different four groups. Let name them Part (A, B, C & D).
Let Part A be Aa and Aa... If both traits crosses; we have
A a
A AA Aa
a Aa aa
Hence, there is a total of 4 combinations
Let Part B be Bb and Bb... If both traits crosses; we have
B b
B BB Bb
b Bb bb
Hence, there is a total of 4 combinations
Let C be Cc and Cc ... If both traits crossses; we have
C c
C CC Cc
c Cc cc
Hence, there is a total of 4 combinations
Let D be Dd and Dd... If both traits crosses; we have
D d
D DD Dd
d Dd dd
Hence, there is a total of 4 combinations
A genotype has the 4 groups together. Therefore the possible number of ways of forming the genotype = 4 x 4 x 4 x 4= 256
