Is HSC biology module 5 hard to do well in?

I worked with an above average student who had jumped two years throughout their high school journey. They wanted to get top in their class for biology but had found they couldn’t finish their year 11 exams in enough time to catch their silly mistakes. Going into year 12, knowing every mark counted towards their ATAR, they wanted to be confident in their exams. Realising that they were great with their grasp of content, but not so much with their speed or accuracy in their exams, I created this curated list of heredity questions. I also provided them with exemplar answers, ones the markers want to see. This way their writing is clear and concise so they have the comfort of knowing they will get their exam finished. Remember, 50% of your mark will come from knowing the content and 50% of your mark will come from knowing how to show the markers you know the content.

How do I get a band 6 in HSC biology?

Fortunately, we have created a straight path to success for you, our HSC Biology Open access resources will give you everything you need to excel at the HSC biology course and earn yourself a band 6. We can’t do the work for you but we can give your the tools you need to do well in biology. Just answer our questions and mark your answers and those around you will wonder what it is you are doing to improve so rapidly.

HSC Biology Module 5 Questions: Short answer

Attempt the following 48 marks of short answer questions before marking your HSC biology heredity questions to get the most from your study time.

Question 1.

A mule is a hybrid animal which is unable to have offspring. It is created through breeding a donkey with a horse. Mules are found to be useful as pack animals due to their ability to travel in rough terrain. 

1a) Complete the following diagram for meiosis to demonstrate the expected genetic information of each cell. [2 marks]

1b) Complete the following diagram for meiosis to demonstrate the expected genetic information of each cell when there is an odd number of chromosomes for the starting cell.

1c)  A donkey has 62 chromosomes and a horse has 64 chromosomes. How many chromosomes would you expect a mule to have? [1 mark]


1d) Justify why a mule breed with a mule can’t have offspring  [3 marks]


Question 2.

Evaluate the usefulness of models in science to communicate scientific concepts. [6 marks]


Question 3.

3a) Explain why external reproduction often generates more offspring than internal [3 marks]


3b) Outline the significance of internal fertilisation for the evolution of ground dwelling animals [3 marks]


Question 4.

4a) Compare and contrast meiosis and mitosis [4 marks]


4b) Explain how genetic diversity is created in meiosis [4 marks]


Question 5.

5a) Explain why DNA replication is a semi-conservative process [2 marks]


5b) Outline the process of DNA Replication [6 marks]


5c) Create a table to compare polypeptide synthesis and DNA replication. [4 marks]

Answers to HSC biology heredity questions

My first ever student had done 15 papers before they sat their trial paper for advanced math. Yet they didn’t do well, relatively speaking. That’s when they called me in. I sat down with them and went through what they were doing when they were studying. They were doing everything right. Just as I was leaving, I asked them what they were averaging in the study papers. This is when they revealed they weren’t marking them to preserve their motivation. They did 3 papers and marked each one the following fortnight. Like that they had improved by 20%, more then the 15 papers they had done. Thats why we provide exemplar answers to the HSC biology heredity questions.

Biology Module 5 exam: Multiple Choice Answers

  1. D: Sexual reproduction is when two different genetic lines join together, D is the only viable option – A is incorrect as pollination leads to the dispersal of seeds – B is for asexual reproduction – C is incorrect
  2. C: First the egg needs to be released via ovulation occurs before the egg is picked up by the tube. It can then be fertilised through the union of sperm and egg. It then needs to implant in the uterus before a placenta can form.
  3. D: Incomplete dominance is when the offspring shows a mix of both parents phenotype.
  4. B: A + T + G + C = 100 | A = T (DNA is double stranded) | G = C (DNA is double stranded) | 2 A + 2 G = 100 | A + G = 50
  5. A: In meiosis II
  6. A: Identical twins have the same genotype, however, their lifestyle choices make them look different.
  7. D: The quaternary structure is when multiple polypeptides in their tertiary form are joined together.
