Introduction Enzymes are biological catalysts that speed up chemical reactions in the body. Botanic gardens are sites where many plant species are planted in controlled environments to maintain their species.

Considering the colour change, this indicates that there is higher concentration of apple juice in the quantity which could be used for cordials and dilute squash drink productions. Independe The sampling of A standard quadrat was used during the sampling of the nt different reactional reactional areas was conducted under uniform dimensions, areas: Time gap between boiling the water and pouring the lemon Juice into it was controlled, by checking the temperature of water.

Remove and pour contents of each into a filter-papered funnel inside a 20ml measuring cylinder. In effect, the concentration of pectinase had varying effects on the results Graph 1.

Helicase unwinds the double helix and separates the two strands by breaking hydrogen bonds. Discuss the international measures that would promote the conservation of fish.

IB Correlations for Biology

Calcium, magnesium and potassium ions are leached out of the soil, reducing fertility and plant growth. Water is needed for vital functions, so only animals that can conserve water are found in deserts.

Increasing the concentration of pectinase, in grams, in a 50ml solution, will not have any bearing on juice production, volume or concentration, of 5g of apple when reacted with the solution; any difference that occurs is entirely due to chance or random variables not under control, and not due to the manipulation of the independent variable.

What are the essential variables that need to be kept constant e. There are 20 different amino acids in polypeptides synthesized on ribosomes.

This is by far not an exhaustive list and you are free to propose any sort of question that you would like to study that is feasible to carry out at LCHS and surrounding areas in Sanford. Keep one cuvette named F with distilled water as a control. That would be useful in industry to enhance products and profit, resulting in more successful company.

In effect, the concentration of pectinase had varying effects on the results Graph 1. Smoking is one such stress, and smokers should ensure they eat foods and drinks containing vitamin C.

Retrieved December 20,from Biology Mad: Experiments with bacteria populations in the lab of Russian ecologist G. Divide into five 10ml measuring cylinders using a funnel and the pipette. Outline the damage caused to marine ecosystems by the over-exploitation of fish.
