Question and answers already passed
2025/2026
Know the order to know what makes up what group. Biological Organization: - correct answer
✔biosphere →ecosystems → communities → populations → organism →organs
→tissues →cells → organelles → molecules.
Bacteria - correct answer ✔tiny, single-celled organisms
Archaea - correct answer ✔A group of microorganisms that are similar to, but evolutionarily distinct
from bacteria.
Eukarya - correct answer ✔All cell based organisms containing nuclei or membrane bound organelles
the difference between
prokaryote and eukaryote - correct answer ✔Prokaryote: no nucleus
Eukaryote: nucleus
natural selection - correct answer ✔the process through which populations of living organisms adapt
and change
Hypothesis - correct answer ✔a testable explanation for a set of observations based on the available
data and guided by inductive reasoning
Qualitative vs. Quantitative Data - correct answer ✔Qualitative data is representing information and
concepts that are not represented by numbers while Quantitative data is measures of values or counts
and are expressed as numbers.
, Common (4) elements in humans - correct answer ✔hydrogen, oxygen, carbon, nitrogen
atomic number - correct answer ✔the number of protons in the nucleus of an atom
atomic mass - correct answer ✔Number of protons and neutrons
isotopes - correct answer ✔A similar atomic number but have different mass numbers
Pattern of periodic table - correct answer ✔Metals, Metalloids, Nonmetals
Know how to determine the number of electrons in the shell - correct answer ✔The maximum number
of electrons that can be filled in the second shell (L - Shell) = 2(2)2 = 8 electrons. Q
covelant bond - correct answer ✔The atoms are bound by the sharing of electrons
ionic bond - correct answer ✔One atom donates an electron to stabilize the other atom
Non-polar - correct answer ✔equal sharing of electrons
Polar - correct answer ✔having a pair of equal and opposite charges
Identify compound - correct answer ✔A compound is identified by its name and chemical fomula
Examples of identifying compounds - correct answer ✔Water (H20)
Sodium chloride (NaCl)
