A Level Biology Paper 1
Questions And Verified Answers
What is the full name of ATP? - Correct Answer - Adenosine triphosphate.
What molecule is formed when two molecules of glucine are joined together?
- Correct Answer - Water.
Why are no organelles visible in the cytoplasm of a red blood cell? - Correct
Answer - The cytoplasm of a red blood cell is filled with haemoglobin.
Why is it when cells are prepared for using the electron microscope, they are
stained byt the appearance of the cell surface membrane appears as two
dark lines? - Correct Answer - The 2 lines are the phospholipid bilayer and it
shows the inside and outside of the membrane.
When asked a question about taxon, what must you have in mind? - Correct
Answer - Kingdom, Phylum, Class, Family, Order, Genus and Species.
What does meiosis do to the number of chromosomes and what symbol is
used for that? - Correct Answer - Halves the number of chromosomes and n.
What is one advantage of sexual reproduction of a species? Suggest and
explain this. - Correct Answer - It increases genetic diversity so there's a
greater chance of survival.
What does more diversity of a species lead to? - Correct Answer - More
animals...more habitats and niches.
The scientists decided to collect animals from the soil samples for 40
minutes. How did the scientists decided that 40 minutes was an appropriate
time? - Correct Answer - Through a trial, they count at 20 minutes then 30
minutes then at 40 and at 50+ minutes they find the same results as 40 and
realise anything above then wastes time so 40 is the optimum time.
How do you find out the range in biology? - Correct Answer - (From where to
where?) e.g.
