Which of the following best explains the maintenance of a nearly constant average temperature on the surface of the Earth? | The amounts of solar energy absorbed and radiant energy emitted by the Earth exist in equilibrium. |
Acid | A substance with a pH less than 7 |
Activation energy | The minimum amount of energy required to start a chemical reaction. |
Active immunity | Protection against a specific pathogen resulting from the production of antibodies in response to the presence of specific antigens. |
Active transport | Movement across a cell membrane thag travels against the concentration gradient and this requires energy. |
Adaptive defense | A specific response by the immune system to a given pathogen. |
Adaptive immune system | A kind of passive or active immunity in which antibodies to a particular antigen are present in the body. |
Adhesiveness | A measure of how well dissimilar particles or surfaces cling to one another. |
Adrenal | A gland above the kidney that produces hormones to regulate heart rate, blood pressure, and other functions. |
Allele | A specific copy of a gene. |
Allergies | An immune response to a foreign agent that is not a pathogen. |
Alveoli | Tiny air sacs in the lungs where exchange of oxygen and carbon dioxide takes place. |
Amino Acids | The monomers that make up proteins. |
Anaphase | The stage in mitosis in which the chromosomes are pulled apart to the pikes and cell division begins. |
Anaphase 1 | The stage of meiosis 1 in which homologous chromosomes move to opposite ends of the cell. |
Anaphase 2 | The stage in meiosis 2 in which sister chromatids separate and move to opposite ends of the cell. |
Anatomical position | Standard positioning of the body as standing; feet together; arms to the side; with head, eyes, and palms of hands forward. |
Anion | A negative charged ion. |
Antibody | A blood protein that counteracts a specific antigen. |
Antidiuretic hormone | A secretion from the pituitary gland that increases the amount of water able to be reabsorbed from a collecting duct. |
Antigen-presenting cell | A cell that displays foreign antigens with major histocompatibility complexes on their surfaces. |
Antimicrobial | A substance that kills or inhibits growth of micro-organisms with minimal damage to the host. |
Anus | The opening of the refrain from which solid waste is expelled. |
Apocrine sweet glands | Accessory structures of the dermis that are in physical association with hair follicles, producing a secretion with an odor (possibly a sec pheromone to humans). |
Arteries | Vessels that carry blood away from the heart toward other body parts. |
Asthma | A lung disease characterized by inflamed, narrowed airways and difficulty breathing. |
Atom | The fundamental constituent of matter that retains the properties of an element. It is the smallest unit that has a unique identity. |
Atomic mass | The sum of the masses of protons and neutrons in one atom of an element. |
Atomic number | The number of protons in the nucleus of an atom. |
Autoimmune disease | A pathology that results from the immune system mistaking part of the body as a pathogen. |
Autonomic nervous system | The part of the PNS (peripheral nervous system) that regulates unconscious body functions such as breathing and heart rate. |
Axon | A nerve fiber that carries a nerve impulse away from the neuron cell body. |
B cells | Lymphocytes that mature in bone marrow and make antibodies in response to antigens. |
