2026 QUESTIONS WITH SOLUTIONS GRADED
A+
◉ Levels of Organization. Answer: atoms, molecules and
macromolecules, cells, tissues, organs, organisms, population,
community, ecosystem, biosphere
◉ Key Features of Life. Answer: cells and organization, energy and
metabolism, response to environmental changes, regulation and
homeostasis, grown and developments, reproduction, biological
evolution
◉ All Cells. Answer: enclosed by a membrane and use DNA
◉ Eukaryotic Cell. Answer: has membrane-enclosed organelles
- plants, animals, fungi
◉ Prokaryotic Cell. Answer: simpler and smaller, does not contain a
nucleus or other membrane-enclosed organelles
◉ Negative Feedback. Answer: as more product accumulates, the
process that creates it slows and less of the product is created
,◉ Positive Feedback. Answer: as more of a product accumulates, the
process that creates it speeds up and more of the product is
produced
◉ Two Main Types of Scientific Inquiry. Answer: discovery science,
hypothesis-based science
◉ Discovery Science. Answer: describes natural structures and
processes, based on observation and the analysis of data
◉ Hypothesis. Answer: a tentative answer to a well-framed question
◉ A Theory Is. Answer: broader in scope than a hypothesis, general
and can lead to new testable hypotheses, supported by a large body
of evidence in comparison to a hypothesis
◉ Matter. Answer: consists of chemical elements in pure form and in
combinations called compounds
- anything that takes up space and has mass

substances by chemical reactions
, ◉ Compound. Answer: substance consisting of two or more
elements in a fixed ratio
- has characteristics different from those of its elements
◉ Essential Elements. Answer: carbon, hydrogen, oxygen, and
nitrogen
- 95% of matter
calcium, phosphorus, potassium, and sulfur
-4%
remaining amount are trace elements
◉ Atom. Answer: the smallest unit of matter that still retains the
properties of an element
- each element consists of unique atoms
◉ Neutron. Answer: no electric charge
◉ Proton. Answer: positively charged particle
- determines the elements atomic number
