This is the first stage of mitosis and meiosis whereby the specialized cell is undergoing, cell division.

The nuclear envelope starts to break down

The chromosomes start to condense during this phase, from being loose to being tight, held together at the middle.

The mitotic spindles start forming, as well from the spindle apparatus.

Brainliest please.

Species a diverged from species b 60,000 years ago. On a particular gene, they have 15 nucleotide differences. How many nucleoti
a_sh-v [17]

The given question says that b species diverged around 60,000 year ago from species a. Since the divergence, they have a nucleotide difference of 15 nucleotide.

We need to find out the nucleotide difference in another 240,000 year, which means a total of 300,000 year since divergence.

The nucleotide difference in 60,000 years = 15 nucleotide.

The nucleotide difference in 1 year =\frac{15}{60,000}  nucleotide.

The nucleotide difference in 300,000 years = \frac{15}{60,000}\times 300,000 nucleotide.

The nucleotide difference in 300,000 years = 75 nucleotide.

Hence, after another 240,000 years or 300,000 years since divergence, the species and species b would show a difference of 75 nucleotide.

In another 240,000 years, there would be 60 nucleotide difference, as 15 of the nucleotide are already different in initial 60,000 years from the total of 75 nucleotide difference in 300,000 years. So, 60 (75-15) nucleotide difference would be observed in next 240,000 years.

How is the chemical compositon of hydrothermal vents fluid different from surrounding sea water
ICE Princess25 [194]
HEY THERE!!

When seawater seeps down into the ocean crust and is heated by the magma, it undergoes lots of chemical reactions. When the fluid rises up through the seafloor, it carries many new chemicals with it, such as-- copper and zinc.
These chemical reactions also remove chemicals from the seawater, such as oxygen and magnesium.

So clearly vebtus fluid is different from sea water .
