If the average length of a double helix in human chromosome is 3.9 cm, approximately how many base pairs are present in such chr
ikadub [295]

Answer:

The average length of a double helix in human chromosome whose length is 3.9 cm has approximately 114.7 million base pairs

Explanation:

Lenght of DNA = number of base pairs * distance between consecutive base pairs

The distance between two consecutive base pairs bonded by hydrogen bonds is 0.34 nm.

If the average length of a double helix DNA molecule in human chromosome is 3.9 cm, the average number of base can then be calculated using the formula below:

Average number of base pairs = length of DNA ÷ distance between consecutive base pairs

Average number of base pairs = 3.9 cm/ 0.34 nm = 0.039 m/ 0.00000000034 m

Average number of base pairs = 114705882.4

Therefore, the average length of a double helix in human chromosome whose length is 3.9 cm has approximately 114.7 million base pairs

You are riding in an elevator that is accelerating upward. Suppose you stand on a scale. The reading on the scale is __________.
trasher [3.6K]

Answer:

Option B, weight greater than your true weight

Explanation:

When a person stand on a scale in an elevator, his inertia tries to remain constant and stable. Thus when a lift starts moving upward it presses against  the feet of that person in order to lift him/her up. In doing so an apparent weight is applied on the person which do not change with speed and it is due to this weight that scale shows a higher reading when elevator moves up.

Hence, option B is correct.
