PAPER 2026 QUESTIONS WITH ANSWERS
FULL SOLUTION.
Community. Answer: Twelfth level. Populations can interact with
each other in positive and negative ways, and together they form this.
Ecosystem. Answer: Thirteenth level. Consists of all the living
things in a particular area together with the abiotic, or nonliving, parts of
that environment.
Biosphere. Answer: Fourteenth level. The highest level of
organization in living systems. The collection of all ecosystems on
Earth. Includes all habitable zones on the planet, including land, soil,
and rocks to a great depth in the Earth's crust; water and ice; and the
atmosphere to a great height.
Emergent Properties. Answer: Characteristics of a system that are
not present in any of its component parts.
, Biology. Answer: The scientific study of life and is the branch of
science that studies living organisms and the way organisms interact
with their environments.
Homeostasis. Answer: The ability or tendency of organisms and
cells to maintain stable internal conditions.
Nutrient. Answer: Any matter an organism needs but cannot make
for itself.
Energy. Answer: The capacity to do work or to make a change in the
location, temperature, or structure of matter. Does not have mass and it
does not take up space, but it can be measured in terms of what it does.
Growth. Answer: An increase in size.
Development. Answer: Structure and function change in an orderly
way as an organism passes through its life cycle. An individual's pattern
of _______ is partly determined by genetic instructions.
Reproduction. Answer: Occurs when an individual organism passes
on its genetic information to a newly independent organism, or
offspring.
, Evolution. Answer: A scientific theory that explains how and why
life changes over time. Provides the explanation for why all living
organisms share profound similarities, and yet, the life forms on our
planet are so incredibly diverse.
Natural Selection. Answer: Individuals are always a bit different
from their parents and from each other, partly because of changes to
their genes. These differences may be helpful or harmful to the
individuals that inherit them. In nature, individuals often have very low
odds of surviving to reproduce. Individuals with slightly harmful or even
average characteristics might be less likely to make it, and those with
traits that fit in very well with the local habitat will have the greatest
chance to survive and reproduce. This sorting process goes on
generation after generation.
Atomic Mass. Answer: The sum of the number of protons and the
number of neutrons. The mass of an atom.
Atomic Number. Answer: The number of protons in an atom,
displayed for each atom in the periodic table.
Chemical Bonds. Answer: Attractions between atoms that hold
atoms and molecules together.
, Covalent Bonds. Answer: Strongest chemical bond. Occurs between
atoms of in the same molecule. Electron pairs are shared, creating a
strong bond between atoms.
electron. Answer: Subatomic particle, located in shells on the
outside of the nucleus, has a negative charge and almost no mass.
electronegativity. Answer: A measure of the tendency of an atom to
attract a bonding pair of electrons. How strongly does an atoms attract
bonding electrons to itself?
element. Answer: Atoms with unique properties, designated by the
atomic number.
hydrogen bond. Answer: Weak chemical bond. Occurs between
atoms in different molecules or parts of molecules. Weak electrostatic
attraction between areas of molecules with opposite partial charges.
ion. Answer: Positively or negatively charged atom.
ionic bond. Answer: Moderately strong chemical bond. Occurs
between atoms in the same molecule. Electrons transfer from one atom
to another.
