forming hydrogen bonds

Answer 60

is manufactured by re-arranging the carbon skeleton and other elements in food molecules

Answer 61

cannot be stored in a cell for future use

Answer 62

is both used and made in cellular respiration

Answer 63

is a carbohydrate

Answer 64

mitochondria

Answer 65

rough endoplasmic reticulum

Answer 66

golgi apparatus

Answer 67

WBCs manufacture digestive enzymes for intracellular destruction

Answer 68

Destruction of phagocytized material takes place in the cytosol of the WBC

Answer 69

Phagocytosis is one form of active transport across the plasma membrane of the cell.

Answer 70

Lysosomes are unique to some WBCs; not all cells have lysosomes since not all cells phagocytize bacteria.

Answer 71

cytokinesis

Answer 72

karyokinesis

Answer 73

are arranged as a bilayer with their polar heads sandwiched between the nonpolar tails

Answer 74

are arranged in a bilayer with their non-polar tails sandwiched between polar heads

Answer 75

around a central layer of cholesterol

Answer 76

prevent the passive transport of most water soluble solutes across the membrane

Answer 77

serous membrane

Answer 78

epithelium

Answer 79

skeletal muscle cell

Answer 80

is diploid

Answer 81

is the origin of the tissues creating the embryo, but not the tissues that produce the placenta

Answer 82

implants in the uterus

Answer 83

is another name for an egg in the ovary

Answer 84

produces the three embryonic germ layers

Answer 85

is called cleavage

Answer 86

results in fertilization

Answer 87

results in morphogenesis

Answer 88

would be lined by an epithelial tissue

Answer 89

is a space through which light is meant to pass

Answer 90

is the hollow interior of an organ

Answer 91

the surface of the body is considered a lumen, since it is covered with epithelial tissue

Answer 92
