Basic Concepts in Elementary Biology
Cell Structure and Function
Cells are the basic units of life. Two basic types – prokaryotic cells, that lack a nucleus and organelles, and eukaryotic cells that have a nucleus and organelles like mitochondria and ribosomes.
Genetics and Heredity
The study of how traits are passed from parents to offspring. Genetic information is carried by DNA. RNA helps in protein synthesis.
Evolution and Natural Selection
The process that species change over time is evolution. Organisms adapt to their environment by natural selection.
Ecology and Ecosystems
Ecology is the study of organisms interacting with each other and their environment. An ecosystem includes all living (biotic) and non-living (abiotic) components in an area.
Photosynthesis and Cellular Respiration
Photosynthesis is the process that plants convert sunlight into chemical energy or glucose which is then converted into energy (ATP) by the plant, called cellular respiration.
Human Anatomy and Physiology
Human anatomy is the study of the body’s structure, while physiology is the study of how the body functions. Major systems include the circulatory, respiratory, and nervous systems. Anatomy and Physiology practice questions Anatomy and Physiology practice II
Microorganisms and Viruses
Bacteria, fungi, and protists are essential for decomposition and nitrogen fixation. Viruses are infectious agents that require a host cell to replicate.
Plant Biology
Roots, stems, and leaves allow plants to ingest nutrients perform photosynthesis. Plants reproduce through seeds, spores, or vegetative parts.
Biochemistry
The study of the chemical processes in living organisms. Important biomolecules are carbohydrates, proteins, lipids, and nucleic acids.
Cell Division
Cells reproduce by Mitosis (two identical child cells), and meiosis, which produces four genetically diverse gametes (sex cells).

how many marks does each question carry?
Usually 1 mark per question. A few tests will subtract a mark for a wrong answer, so watch out for that – but not too common.
Can someone explain why answers for 5 and 6 are from a lesser concentration to a higher??
I thought because solutions seek to be isotonic, that solutions would disperse to move *from* a high concentration *to* a lower one (and therefore be balanced on both sides of the membrane, or generally be evenly dispersed if not across a membrane)
If they’re moving from a lesser concentration to a higher (like the answer key says, twice) wouldn’t that be a form of active transport? and therefore not be diffusion/osmosis, which are both passive??
I know this is YEARS too late but basically during osmosis WATER moves from an area of high concentration of water to low concentration of WATER. Therefore, when there is a high concentration of WATER there is a low concentration of SOLUTES and when there is a low concentration of WATER there is a high concentration of SOLUTES. Those questions were asking about the solute concentration. Hope this makes sense and helps you and others with the same question!
Osmosis goes both ways to equalize – diffusion goes from greater to lesser
yes osmosis goes in both direction ,but net direction of water is from its lower water potential to its high
good point – could be interpreted either way — During prophase and metaphase of mitosis, each chromosome exists in the above state. For humans, this means that during prophase and metaphase of mitosis, a human will have 46 chromosomes, but 92 chromatids (again, remember that there are 92 chromatids because the original 46 chromosomes were duplicated during S phase of interphase)
Can u please upload more quiz
Thank you so much Brian, these tests have been so helpful!
