Bio True/ False

True

Carbohydrates and fats are both used as energy sources.

FALSE descriptive

Collecting data based on observation in nature is an example of an analytical study.

•FALSE •Kreb's Cycle

Glycolysis functions to transfer chemical energy from pyruvate to energy carriers

True

It is important for scientists to communicate their results to fellow scientists because the quality and accuracy of the scientific work can be enhanced by input, further review, and possibly even repetition by other scientists working in the same field.

True

Land biomes are most commonly defined by their climate and physical characteristics that influence the dominant plant life and subsequently animal life in them.

True

Neighboring water molecules are held together with hydrogen bonds because partially negatively charged oxygen atoms and partially positively charged hydrogen atoms on separate water molecules are attracted to one another.

True

Pancreatic cancer is an especially dangerous disease in humans because the pancreas is an organ that manufactures many different kinds of digestive enzymes.

FALSE Bacteria

Plants make up the oldest fossil found on Earth.

True

Scientific literacy means that you understand the process of science and basic scientific facts and theories.

FALSE negative

Subatomic particles that possess a singe positive charge and surround the nucleus are electrons.

FALSE increased

The Cambrian explosion decreased the diversity of animal life on Earth.

true

•A component of our immune system's first line of defense is the acidic environment in the digestive system.

true

•A prokaryote that uses carbon dioxide for photosynthesis and sunlight for energy is called a photoautotroph.

•FALSE •mother

•All mitochondrial DNA is inherited from the father.

•FALSE •bilateral

•An animal that can be divided by just one vertical plane into two halves that mirror each other displays radial symmetry.

•FALSE •Catabolic

•Anabolic reactions release energy by breaking down complex molecules.

true

•Every gene in a human occupies a specific position or locus on a chromosome.

True

•Every living organism is composed of one or more cells, and all living cells arise from preexisting cells.

True

•Genetic drift is a chance evolutionary change occurring in small populations.

false boys

•Girls inherit an X chromosome from mom and a Y chromosome from dad.

True

•Homologous chromosomes consist of a maternal and paternal copy of each chromosome.

False 23

•Humans have 24 pairs of chromosomes.

•FALSE •artificial

•Humans simulate the process of natural selection when they use natural selection to develop new varieties of crop plants that better meet the needs of farmers.

•FALSE •Mitosis

•Meiosis is the process by which organisms grow and maintain their tissues.

true

•Memory cells include B cells and T cells that remain in the body for long periods of time after the first exposure to a pathogen.

true

•Pangaea is an ancient, giant continent.

FALSE rapidly

•Prokaryotes reproduce more slowly than single-celled eukaryotes because prokaryotes have much less DNA than eukaryotes.

true

•The development of upright posture in hominins is likely an adaptation for living on the ground instead of in the trees.

true

•The structures that carry signals away from the cell body of a neuron are called axons.

true

•When ATP breaks down into ADP and a phosphate group, energy is released and can power cellular activities.
