Answer:
No we don't.
Explanation:
Us humans keep reproducing without a care in the world. Some newborns make it out alive to get a chance in life and some die. It is the circle of life for us. Out of the womb into the tomb. We don't follow the rules of mother nature because we are dealing with better things (jobs, school, etc.)
The correct answer is A) Foot. The irregular plural form of this noun is feet. Hope this helps.
The second option is definitely more complicated
First add the whole numbers.
Then find the LCM (least common multiple) of 3 and 2, which are the denominators of both fractions. In this case, the LCM of 3 and 2 are 6.
As you can see in the photo, I multiplied a number than can result in 6 in both denominators. Then multiply that same number to the numerators.
Finally, add 21+2, but keep the denominator as 6.
This is how I learned it, hope it helps.
