Questions AND 100% CORRECT ANSWERS 2024-
2025
Which chamber of the heart pumps blood out of the heart into the circulatory system? -
✔✔The left ventricle.
Explanation:
The left ventricle pumps blood into the circulatory system via the aorta.
Where are vacuoles found? - ✔✔Inside plant and animal cells.
Explanation:
Vacuoles are organelles used for storage and/or maintaining cell pH and pressure.
What do ribosomes do? - ✔✔Build proteins from amino acids
Explanation:
Ribosomes are molecules which create proteins by linking amino acids together in a particular
order, using messenger RNA molecules as a blueprint.
What is the name of the organelle(s) where photosynthesis takes place? - ✔✔Chloroplasts
Explanation:
Chloroplasts are found in plant cells and contain chlorophyll which converts the energy from
sunlight into sugars.
What is mitosis? - ✔✔The division of a cell nucleus.
,Explanation:
During mitosis, a cell nucleus divides, producing two identical sets of chromosomes.
Name the four primary nucleobases found in DNA - ✔✔cytosine (C), guanine (G), adenine
(A), and thymine (T)
If a genotype consists of two identical alleles, is it homozygous or heterozygous? -
✔✔homozygous
A relationship between two organisms which is of benefit to both, is what kind of symbiosis? -
✔✔Mutualism.
e.g. the relationship between clownfish and sea anemones - the clownfish clean and feed the
sea anemones, while the sea anemones protect the clownfish from predators.
In taxonomy, which ranking is most inclusive, Kingdom or Genus? - ✔✔Kingdom
Explanation:
Kingdom is the second highest rank, containing Animalia, Plantae, Fungi, Protista, Archaea and
Bacteria. Genus comes below Family and above Species.
Casein, found in milk and consisting of amino acids, is what kind of molecule? - ✔✔Protein
Prokaryotes reproduce through which mechanism? - ✔✔Binary fission.
Explanation:
This is a form of asexual reproduction, where a parent cell divides into two identical daughter
cells.
, What is the final stage of mitosis? - ✔✔Telophase.
Explanation:
During telophase, the duplicated genetic material in a parent cell is split into two identical
daughter cells.
Define sublimation - ✔✔It's the change of state directly from solid to gas.
What process produces lactic acid in muscles? - ✔✔Fermentation.
Explanation:
During fermentation, glucose is converted to lactic acid.
What is active transport and where does it occur? - ✔✔The movement of molecules from an
area of lower concentration to an area of higher concentration. It occurs across cell
membranes.
What is cytoplasm? - ✔✔The thick fluid that fills cells
What are the four fundamental states of matter? - ✔✔Solid, liquid, gas and plasma
How many times more basic is pH 10 compared to pH 8? - ✔✔100
Explanation:
The pH scale is logarithmic with a basis of 10, so each unit difference corresponds to a factor of
10.
