IDENTIFICATION A. Directions: Identify the following statements Write your answer on the space provided before each number 31. in biology, it is any difference between cells, individual organisms or groups of organisms of any species 32. It is the total number of genetic characteristics in the genetic makeup of a species animals and plant that contain millions of cells. 33. It consists of the large number and all differentkinds, shapes, colors and sizes of organisms that inhabit the Earth 34 .Bacteria that produce their own food 35. Animals with one cell 36. It is the evolutionary process by which populations evolve to become distinct species 37. It is the change in the heritable characteristics of biological populations over successive generations. 38 It deals with the variations in ecosystems within a geographical location and its overall impact on human existence and the environment 39. It is the changing of the structure of a gene, resulting in a variant for that may be transmitted to subsequent generations, caused by the alteration of single base units in DNA, 40. They are all living things whether plants and animals are made up of this basic unit of life following are ahintir or hiotic components of the ecosystem

Variation, in biology, any difference between cells, individual organisms, or groups of organisms of any species caused either by genetic differences (genotypic variation) or by the effect of environmental factors on the expression of the genetic potentials (phenotypic variation). Variation may be shown in physical appearance, metabolism, fertility, mode of reproduction, behaviour, learning and mental ability, and other obvious or measurable characters.
