Yes, it also holds all the organelles.
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
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.
Answer: B
Explanation: I think the answer is B because natural selection leads to evolution because they happen in a line or like a chain reaction.
