ENSF 461 MIDTERM UPDATED EXAMINATION
TEST 2026 TESTED QUESTIONS WITH FULL
SOLUTION GRADED A+
◉ reproduction. Answer: all organisms reproduce their own kind.
◉ growth and development. Answer: information carried by genes
controls the pattern of growth in all organisms.
◉ energy use. Answer: every organism takes in energy, converts it to
useful forms, and expels energy. Ex. elephant; an elephant is taking
in energy by eating a plant. it can use the energy to move. it also
releases energy as heat.
◉ order. Answer: each living thing has a complex but well-organized
structure.
◉ cells. Answer: all living organisms consist of cells. some living
organisms have just one cell, but others have trillions.
◉ response to the environment. Answer: all organisms respond to
changes in the environment. many of these responses help to keep
an organism's internal environment within narrow limits even when
,the external environment changes a lot. Ex. elephant: an elephant is
responding to the heat of the day by taking a bath, which helps keep
its body temperature steady.
◉ evolution. Answer: individuals with traits that help them survive
and reproduce pass the genes for those traits to offspring. over many
generations, such adaptations drive the evolution of populations. Ex.
modern elephants and woolly mammoths evolved from a common
ancestor species that lived until about 5 million years ago.
◉ The levels of biological organization. Answer: biosphere,
ecosystem, community, population, organism, organ system, organ,
tissue, cell, organelle, molecule, atom
◉ Biosphere. Answer: consists of all life on Earth and all of the
environments that support of life, from the deepest oceans to high in
the atmosphere.
◉ Ecosystem. Answer: includes all the living organisms in one
particular area as well as the nonliving components that affect life,
such as soil, air, and sunlight.
◉ Community. Answer: consists of all the interacting populations of
organisms occupying an ecosystem. includes plants, animals, and
even microscopic organisms.
, ◉ Population. Answer: a group of interacting individuals of one
species.
◉ Organism. Answer: an individual living being
◉ Organ System. Answer: a group of organs that work together to
perform a vital body function.
◉ Organ. Answer: consists of multiple tissues that cooperate to
perform a specific task. a part of an organism that is typically self-
contained and has a specific vital function.
◉ Tissue. Answer: an integrated group of similar cells that work
together to perform a specific function.
◉ Cell. Answer: the fundamental unit of life. the smallest structural
and functional unit of an organism. microscopic and consisting of
cytoplasm and a nucleus enclosed in a membrane.
◉ Organelle. Answer: a component of the cell that performs a
specific function. within the cell.
◉ Molecule. Answer: a group of atoms bonded together.
