- Nitrogen: Required by proteins. (Remember, nitrogen is included in the amino acid structure) Essential to enzymes required for plant function.
- Calcium: The mineral that strengthens bone and teeth uses calcium. Also important in nerve synaptic transmission of nerve impulses and muscle contraction. Regulates the cell wall construction in plants.
- Phosphorus: Part of the phosphate groups in ATP and DNA molecules. In plants it is needed for cell reproduction and division. It is part of the cell membrane.
- Iron: found in the structure of haemoglobin and essential for the production of red blood cells. It is involved in the light energy transferring compounds involved in photosynthesis in plants.
- Sodium: Major ion associated with the propagation of a nerve impulse. Can replace potassium in some plants.
- Sulfur: It is a component of amino acids.

Why only certain cells produce certain products?
Control genes impede certain genes from expressing themselves and allow others to express themselves/ Thus a liver cell will have basically the same genome as a neuron, but will not express axon development and the neuron will not express bile development.
What does knowing the sequence of an organisms DNA allow researchers to do?
Knowing the sequence of an organism's DNA allows researchers to study specific genes, to compare them with the genes of other organisms, and to try to discover the functions of different genes and gene combinations.
What the mechanisms in mitosis that allow them to produce more identical cells?
DIVISION
What allows humans to have different traits?
Different alleles allow people to have different traits from each other.
Selection in which humans allow only the best organisms to produce offspring?
Artificial Selection
What technology's allow us to alter our genes?
Genetics

What minimum amount of KO2 is required for the apparatus to produce enough oxygen to allow the user 15 minutes to exit in an emergency?
This question can not be answered because KO2 is not an existing chemical compound and the probable mistaken compound K2O (potassium oxide) does not produce free oxygen (O2) in a normally possible chemical reaction.
What happens to allow a new species to develop?
the genes form together
Which of these is not an important part of the process of evolution mutation inheritance adaptation or morphology?
Evolution always involves adaption. The genes that allow an organism (s) to adapt to the environment will pass on their genes.Mutation may produce that gene and the organism will inherit them and their shape (morphology) may be what the genes produce but adaptation is the key to evolution. "The fittest survive".
What do microarrays allow scientists to do?
With a micro array , scientists can examine how active thousands of genes are.
How do you stop growing tall?
that is impossible to stop, you will grow as tall as your body and genes allow.

S the ethics and principles of organic farming and explain why organic products are more expensive than non organic produce?
Many folks believe that using chemicals on plants will allow the fruits to carry over residue and when people eat the fruit, they will then be eating the chemicals. The reason organic food is more expensive is because it is harder to grow and the organic fertilizers and pest control methods are more expensive. I have linked a good article that talks about the major differences between the two types of foods.
What does photosynthesis allow a plant to produce?
Sugars.
Regulatory genes in cells fail to function properly and allow cancer to develop what are they called?
oncogenes
Why are phospholipids used in a membrane?
Phospholipids form membranes because they have hydrophobic (water repelling) heads and hydrophilic (water attracting) tails. The hydrophobic heads will congretate together to avoid contact with the water so the hydrophilic tails will then be left on the outside in contact with the water. This creates a lipid bilayer membrane.
