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:
I think the answer is D
Explanation:
organisms can migrate to other areas and become an invasive species which can cause global problems. other things such as air pollution, water pollution, fires ect dont just remain in one area and all contribute to global warming which is a global issue.

Answer:
Lysosomes
Explanation:
Tay-sachs disease is a rare Autosomal recessive disease that causes neurodegenerative disorder.
Deficiency of an enzyme Hexosaminidase A results in excessive accumulation of gangliosides (sialic acid containing glycosphingolipids) in the brain and nerve cells.
It is a lysosomal storage disease .Absence of the enzyme Hexosaminidase A ,that breakdowns substance like fats results in accumulation of such substance in the lysosomes.Too much accumulation of fats in the lysosomes destroy the cell.
