CLEP Natural Sciences Test 1 Part 01

Cold-blooded animals with bony skeletons, webbed feet, and separate sexes Amphibia (Frogs, Salamanders)
Cold-blooded animals with horny scales and a bony skeleton that lay eggs Reptilia (snakes, lizards)
Cartilaginous fish Chondrichthyes (sharks, rays)
Warm-blooded animals, mostly with wings, that lay eggs Aves (birds—ducks, sparrows, etc.)
Animals with a hairy body and highly developed brain that have live births (in most cases) and produce milk Mammalia // They fertilize internally, give birth to live young (except monotremes), and produce milk (cows, humans, platypus, apes, etc.).
Communication channel between the cytoplasm and nucleoplasm Nuclear pores are holes in the nuclear membrane where the double nuclear membrane fuses together, forming a break or hole, allowing the selective intake and excretion of molecules to or from the nucleus.
Extensions that provide extra surface area for absorption Microvilli are filaments that extend from the cell membrane, particularly in cells that are involved in absorption (such as in the intestine).
Contain digestive enzymes Microvilli also contain enzymes that are involved in digesting certain types of nutrients
Packets that carry substances (hormones, fats, etc.) synthesized within the cell Secretory vesicles are packets of material packaged by either the Golgi apparatus or the endoplasmic reticulum.
Network of membranes that deliver lipids and proteins throughout the cytoplasm Smooth endoplasmic reticulum is a network of continuous membranous channels that connect the cell membrane with the nuclear membrane and is responsible for the delivery of lipids and proteins to certain areas within the cytoplasm
Atoms are held together with network covalent attraction. Silicon carbide (SiC) is held together with network covalent bonds, which creates a crystal entirely from covalent bonds and confers unusual strength (and a high melting point) upon the crystal.
Atoms are held together with covalent attraction. Acetic acid is a molecular compound that is held together with covalent bonds, in which electrons are shared between atoms, so that both atoms in the bond end up having a full octet of electrons.
Atoms are held together with metallic attraction. As a metal, copper is held together by metallic bonds, which involve delocalized d-orbital electrons.
