Tanzania [10]2 years ago

Answer:

Explanation:

Mitochondrial DNA is the small circular chromosome present inside the cell organelle called mitochondria used for energy production. This type of DNA passes from the mother to the offspring. Mitochondrial DNA (mtDNA) has several advantages over nuclear DNA (nDNA):

for species identification purposes

including a higher copy number

a lack of sequence ambiguities from heterozygous genotypes

a faster rate of mutation

Thus, the advantages of keeping some DNA needed by mitochondria in the cell’s nucleus and some in the mitochondria itself are given above.

Africa and South America are 4,000 km apart. If the plates move away from each other at a rate of 30 km per 1 million years, how
yulyashka [42]

Answer:

The majority of the research shows that the plates move at the average rate of between approximately 0.60 cm/yr to 10 cm/yr. Some sources state that in the North Atlantic, the rate of movement is only about 1 cm (about 0.4 in) per year, while in the Pacific it amounts to more than 4 cm (almost 2 in) annually, while others say that plates, in general, travel from 5 to 10 cm/yr.



The Eurasian Plate is moving away from the North American Plate at a rate the is about 3cm per year. That is about the same rate at which your fingernails will grow.



The distance from New York to London is in 3459 miles (5567 km). What will the distance be in 5 million years?.





The distance from New York to London in 5 million years will be 3552 miles (5717 km). So if today it takes us 7 hours and 30 minutes to fly to London at a speed of 460 miles per hour, in 5 million years at the same rate of speed will take us close to 8 hours.

If there are 32 sister chromatids in a normal somatic cell, what is the haploid number for that cell?
malfutka [58]

Answer:

The answer is 16.

Explanation:

Somatic cells include all the cells in the body except for the reproductive cells. Haploid cells are used to represent the reproductive cells which have half the chromosome as the somatic cells. So if there are 32 sister chromatids in a somatic cell, which means there are 16 chromosomes, then the haploid number for it is 16 chromatids. I hope this answer helps.
