Answer:

Total time split from a common ancestor = 30 million

Explanation:

Given:

Number of nucleotide = 6

Number of organism = 2

Rate one nucleotide = 10 million year

Computation:

Total time split from a common ancestor = [Rate one nucleotide / Number of organism]Number of nucleotide

Total time split from a common ancestor = [10 million / 2] 6

Total time split from a common ancestor = [5 million] 6

Total time split from a common ancestor = 30 million

This could affect the chemical balance in his brain, resulting in depression/schizophrenia/other issues, including eating disorders. Cutting down on fats might also result in overeating carbs and protein, which leads to an overbalance of nutrients -- and a host of other health issues.Not getting enough fat could also affect bone growth.</span>

Why do you think air pressure is greatest at the lowest part of the atmosphere?
Alex777 [14]

Answer:

At sea level, air pressure is greatest because it is caused by the weight of the entire column of atmosphere at that altitude over that location. As altitude increases, the column of atmosphere gets shorter, and so less weight is pressing down at a given altitude, so atmospheric pressure is reduced.

They have  helical thickening of lignin in their walls to prevent collapse

Explanation:

the primary function of Xylem and its conducting vessels tracheids is to provide  support and tranport  water and  minerals  in plants.

Xylem vessels  have layers of dead materials in the walls called LIGNIN.   Lignin is a polymer; a  very strong, hard materials that stop water passage  through it,because it contains dead cells,

Therefore  the presence of  deposit of these strong  impermeable, ligified  walls  in its  walls  prevent its collapse during mass flow of water of transpiration pull.
