DEFINITION 55 2.only living things have macromolecules arranged into organelles, as components of cells, that form tissues, that combine to make organs, as components of organisms, that are parts of populations and species, that interact as members of a community
The second law of thermodynamics states that the entropy of an isolated system never decreases, because isolated systems spontaneously evolve toward thermodynamic equilibrium-the state of maximum entropy. TERM 62
DEFINITION 62 The prokaryotes are a group of organisms whose cells lack a membrane-bound nucleus. The organisms whose cells do have a nucleus are called eukaryotes. TERM 63
DEFINITION 63 A eukaryote is any organism whose cells contain a nucleus and other structures (organelles) enclosed within membranes. TERM 64
DEFINITION 64 Diffusion is one of several transport phenomena that occur in nature. A distinguishing feature of diffusion is that it results in mixing or mass transport, without requiring bulk motion.the moving of particles down their concentraion gradient TERM 65
DEFINITION 65 Osmosis is the spontaneous net movement of solvent molecules through a partially permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides.
Mitosis is the process by which a cell, which has previously replicated each of its chromosomes, separates the chromosomes in its cell nucleus into two identical sets of chromosomes, each set in its own new nucleus. TERM 67
DEFINITION 67 Meiosis is a special type of cell division necessary for sexual reproduction in eukaryotes, such as animals, plants and fungi. TERM 68
DEFINITION 68 Cell surface receptors are specialized integral membrane proteins that take part in communication between the cell and the outside world. TERM 69
DEFINITION 69 Catalysis is the increase in the rate of a chemical reaction due to the participation of a substance called a catalyst. TERM 70
DEFINITION 70 Cellular respiration is the set of the metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate, and then release waste products.

Pleiotropy occurs when one gene influences multiple, seemingly unrelated phenotypic traits, an example being Phenylketonuria, which is a human disease that affects multiple systems but is caused by one gene defect. TERM 82

DEFINITION 85 Epithelium is one of the four basic types of animal tissue, along with connective tissue, muscle tissue and nervous tissue.
Sexual reproduction is a process that creates a new organism by combining the genetic material of two organisms.can not happen without meiosis TERM 92
DEFINITION 92 The Red Queen hypothesis, also referred to as Red Queen's, Red Queen's race or The Red Queen Effect, is an evolutionary hypothesis which proposes that organisms must constantly adapt, evolve, and proliferate not merely to gain reproductive advantage, but also simply to survive while pitted against ever-evolving opposing organisms in an ever-changing environment. TERM 93
DEFINITION 93 Fertilization which takes place inside the female body is called internal fertilization. Internal fertilization in animals is done through copulation, which involves the insertion of the penis or other intromittent organ into the vagina or to the cloaca in monotremes, most reptiles, some birds, the amphibian tailed frog and some fish, the disappeared dinosaurs, as well as in other non- vertebrate animals. TERM 94
DEFINITION 94 External fertilization is a strategy of fertilization in which a spermcell unites with an egg cell in the open, rather than inside specialised organs within the bodies of the parents. TERM 95
DEFINITION 95 The central nervous system is the part of the nervous system that integrates the information that it receives from, and coordinates the activity of, all parts of the bodies of bilaterally symmetric animals-that is, all multicellular animals except sponges and radially symmetric animals such as jellyfish.
Endocrine glands are glands of the endocrine system that secrete their products, hormones, directly into the blood rather than through a duct. TERM 97
DEFINITION 97 The endocrine system is referring to the collection of cells, glands, and tissues of an organism that secrete hormones directly into the bloodstream to control the organisms' physiological and behavioral activities. TERM 98
DEFINITION 98 In the animal kingdom, the general term gland falls into two major categories with further subtypes falling under each of these. TERM 99
DEFINITION 99 A hormone is a class of regulatory biochemicals produced in particular parts of organisms by specific cells, glands, and/or tissues and then transported by the bloodstream to other parts of the body, with the intent of influencing a variety of physiological and behavioral activities, such as the processes of digestion, metabolism, growth, reproduction, and mood control. TERM 100
DEFINITION 100 The nervous system is the part of an animal's body that coordinates the voluntary and involuntary actions of the animal and transmits signals between different parts of its body.
