Genetics and Evolution - Biology genes ️physical and biochemical characteristics of every living organism is determined by genes, which are DNA sequences that code for heritable traits that can be passed from one generation to the next chromosomes ️all genes are organized into chromosomes, to ensure that genetic material is passed easily from daughter cells during mitosis and meiosis alleles ️each gene has alternative forms called alleles. I.e. IA IB and i for blood genotype ...

AQA biology a-level paper 2 AQA biology a-level paper 2 describe and explain the steps in the light dependent reaction of photosynthesis - ANS 1. photoionisation: light reaches chlorophyll in PSII, which is absorbed by an electron, which becomes excited and moves to a higher energy level. 2. the electron passes to a carrier protein in the thylakoid membrane, and is passed down a series of carrier molecules called an electron transfer chain. 3. as the electron moves down, energy is lo...

This is one of my favourite pieces of work I have written for the IB. The topic and experiment are very straightforward and concise. I believe its coherence and core focus on the criteria is why it scored so well. It is the ideal example to base your own IA on.

This HL Biology IA was graded a 23/24 and then was moderated down to 22/24. Hopefully this high-quality example will guide you through your own IA and offer insight into the structure of the IA as well. The experiment involved two parts - changing the sucrose concentration when enzyme activity was inhibited by sodium chloride, and changing the sucrose concentration when no sodium chloride was added.

Quality Biology IA received a score of 21/24. The IA can be used as guidance and as inspiration when writing your own IA. Make sure to not copy as that can lead to plagiarism and only use this as a guidance to write your own.

What is the effect of acidic substances (pH below 7) on the reaction rate of catalase with hydrogen peroxide as measured by kilopascals per second? Purpose: There are many factors that can affect enzyme catalysis, such as: temperature, pH, substrate concentration etc. Due to these many factors, the purpose of this investigation is to isolate one factor, pH, by identifying the effect of various acidic substances on the enzyme catalysis of a potato. Abstract: This investigation was c...
