Answer:
age = 63.2 years
Explanation:
Given data
Number of years = 31
number of seconds = 1 billion
Age = ?
Solution
First we convert seconds to minutes
minutes = 1000000000 / 60
minutes = 16666666.667
Now convert minutes to hours
hours = 16666666.667 / 60
hours = 277777.778
Now convert hours to days
days = 277777.778 / 24
days = 11574.074
Now convert days to months
months = 11574.074 / 30
months = 385.802
Now convert months to years
years = 385.803 / 12
years = 32.15
Now add these years with given years
age = 31 + 32.15
age = 63.2 years
I found the rest of the exercise on the internet and these are the options.
"-Undifferentiated vertebrae throughout the body.
-One neck vertebra allowing up and down movement.
-Many neck vertebrae that allow for greater mobility.
<span>-Two neck vertebrae allowing up and down and sideways movement."
The correct answer would be the third. - "</span>Many neck vertebrae that allow for greater mobility." The <span>present-day organism with four limbs has a neck with several vertebrae that allow movements of rotation (mostly because of only two vertebrae at the top of the neck), and side way movements, as well as back and forth movements.</span>

Answer:
The minimum rate of fresh air in the room is 176 moles/min
Explanation:
High exposure of CO₂ has health effects as headaches, increased heart rate, elevated blood pressure, coma, asphyxia, convulsions, etc.
0,500 mole% of CO₂ in air means 0,500 moles of CO₂ per 100 moles of air
As the rate of sublimation of CO₂ is 0,880, the minimum rate of fresh air in the room must be:
X = <em>176 moles of Air/min</em>
<em></em>
I hope it helps!
