exhaled air contains 16% oxygen by volume. Assuming you exhale like the average person does during strenuous exercise (that is,

you exhale 1L of air per breath and you exhale 40 breaths per minute) ad assuming the dive will take 90 minutes, what volume of oxygen will you end up exhaling?

Exhaled air for 90 minutes would be 40 breaths per minute (at 1 litre per breath) x 90 minutes =3600 litres x 0.16= 576 litres of oxygen, In other words, first work out the amount of air breathed out in litres/minute and then multipy by the number of minutes to get the total litres of air breathed out and then multiply that figure by 0.16 (16 % oxygen per volume of air) to get total litres of oxygen breathed out.

Write a Claim based in this question: What happens in the atmosphere and how
gregori [183]

Answer:

The atmosphere is the superhighway in the sky that moves water everywhere over the Earth. Water at the Earth's surface evaporates into water vapor which rises up into the sky to become part of a cloud which will float off with the winds, eventually releasing water back to Earth as precipitation.

Dna is approximately 2.5 nm in length. of an average man is 5 ft 10 in. tall, how many dna molecules could be stacked to extend
Angelina_Jolie [31]
To determine the number of dna molecules that can be stacked as requested in this item, we convert the given measurements in a single unit. For simplicity, we convert all the lengths to meters.

Length of DNA molecule = (2.5 nm)(1 x 10^-9 m/1 nm) = 2.5 x 10^-9 nm

Height of a person = (5 ft 10 in)(12 inches/ 1ft)(2.54 cm/1 in)(1 x 10^-2 m/ 1 cm)
               = 1.778 m

Then, divide the height of the person by the length of a single DNA molecule.

       n = 1.778 m / (2.5 x 10^-9)
       n = 7.112 x 10^8

Hence, the number of DNA would be 7.112 x 10^9.
