AP BIO CONCEPTS EXAM 2025
QUESTIONS AND ANSWERS
A feature of amino acids NOT found in carbohydrates is the presence of - ANS Nitrogen
Atoms
Active Transport - ANS movement of a substance against its concentration gradient (from
low to high concentration)
Alleles - ANS is one of two or more forms of a gene. Different alleles can result in different
traits, such as color. Other times, different alleles will have the same result in the expression of
a gene.
Altruism - ANS selfless concern for the welfare of others.
An action potential - ANS A short-term change in the electrical potential on the surface of a
cell.

,Anaphase I - ANS begins when the two chromosomes of each bivalent (tetrad) separate and
start moving toward opposite poles of the cell as a result of the action of the spindle.
Annelid - ANS Any of various worms or wormlike animals of the phylum Annelida,
characterized by an elongated, cylindrical, segmented body and including the earthworm and
leech.
Arteries - ANS are blood vessels that carry blood away from the heart.
Asexual reproduction - ANS a mode of reproduction by which offspring arise from a single
parent, and inherit the genes of that parent only, it is reproduction which does not involve
meiosis, ploidy reduction, or fertilization.
Auxins - ANS A class of plant growth substances and morphogens.
Binary fission - ANS Asexual reproduction in bacteria.

, Biomass - ANS A renewable energy source, is biological material from living, or recently living
organisms, such as wood, waste, (hydrogen) gas, and alcohol fuels.
Bone - ANS rigid organs that constitute part of the endoskeleton of vertebrates
Bryophytes - ANS embryophytes (land plants) that do not have true vascular tissue and are
therefore called 'non-vascular plants.
Budding - ANS Asexual reproduction in yeasts in which smaller cells grow from a parent cell.
Calcitonin - ANS A 32-amino acid linear polypeptide hormone that is produced in humans
primarily by the parafollicular cells thyroid, and in many other animals in the ultimobranchial
body.
Cartilage - ANS flexible connective tissue found in many areas in the bodies of humans and
other animals
Cellulose - ANS A substance that cannot be broken down by cows.
