How many cell divisions would you think need to occur during the life of an onion? With this thought, describe the marvel of the

continuity of life considering that after thousands of years onions are still onions.

Answer:

The number of cell divisions is too large to even estimate.

Explanation:

Think, for every cell to be formed, a parent cell needed to divide. on top of that, for every parent cell is the result of another parent cell. Think of how small a cell is, and think of how many cells are in the onion.  The fact that onions are still onions is incredible, because a DNA mutation occurs at a very high rate during cell division.  When DNA divides, it sometimes doesn't divide evenly, resulting in too much DNA is one cell, and not enough in another.   Science has proven that the composition of DNA is what makes humans humans, trees trees, and onions onions.  The fact that onions have withstood the millions upon millions of DNA mutations while still remaining a species, is astonishing.

What is the most important factor that determines the rate of diffusion in biological systems?
miv72 [106K]
The factors that determines the rate of diffusion in the biological system include: temperature, size of the particles, diffusion distance and concentration gradients. Of all these factors, the most important  one is the TEMPERATURE.
The relationship between temperature and the rate of diffusion is a direct one, that is, the higher the temperature the higher the rate of diffusion and vice versa. At high temperature the molecules in the particles move faster because they have higher amount of energy.

Sequence of amino acids in a polypeptide chain of protein molecule coresponds to the sequence of nucleotides on mRNA for that pr
tamaranim1 [39]

Answer:

330

Explanation:

A codon is the sequence of three nucleotides on mRNA that refers for particular amino acid during translation (protein synthesis) process. The four nucleotides arrange themselves in various combinations to produce different codons. The tRNA with corresponding anticodon attach the particular amino acid to polypeptide chain during translation.

Remember there is always a stop (UAA) and start codon (AUG) for the synthesis of polypeptide and stop codon does not contribute for any amino acid. It just terminate the polypeptide chain synthesis. We know that a codon is made up of three nucleotide so our calculation will be.

                                     993-stop codon =990

                                     990/3=330

So that's why 330 amino acid will be incorporated in the polypeptide chain.
