10th Grade BiologyMr. Sparaco

GOAL:Assess your understanding about Ecology,

Evolution and Human Anatomy

STANDARD 4—ECOLOGY THE STUDENT WILL EXPLAIN THAT STABILITY IN AN ECOSYSTEM IS A BALANCE BETWEEN COMPETING EFFECTS.

4.1 Define biodiversity as the sum total of different kinds of organisms and is affected by alterations of habitats.

4.2 Analyze changes in an ecosystem resulting from changes in climate, human activity, introduction of nonnative species, or changes in population size.

4.3 Explain how birth, death, immigration, and emigration influence population size in an ecosystem.

4.4 Explain how water, carbon, and nitrogen cycle between abiotic resources and organic matter in the ecosystem and how oxygen cycles through photosynthesis and respiration.

4.5 Use a food web to identify and distinguish producers, consumers, and decomposers, and explain the transfer of energy through trophic levels. Describe how relationships among organisms (predation, parasitism, competition, commensalism, mutualism) add to the complexity of biological communities.

4.6 Distinguish between the accommodation of an individual organism to its environment and the gradual adaptation of a lineage of organisms through genetic change.

STANDARD 5—EVOLUTION THE STUDENT WILL DEMONSTRATE AN UNDERSTANDING OF BIOLOGICAL EVOLUTION AND THE DIVERSITY OF LIFE.

5.1 Summarize the process of natural selection. why natural selection acts on the phenotype rather than the

genotype of an organism why alleles that are lethal in a homozygous individual may be

carried in a heterozygote and thus maintained in a gene pool new mutations are constantly being generated in a gene pool how natural selection determines the differential survival of groups

of organisms

5.2 Explain how variation within a species increases the likelihood that at least some members of a species will survive under changed environmental conditions.

5.3 Explain how a great diversity of species increases the chance that at least some organisms survive major changes in the environment.

5.4 Trace the relationship between environmental changes and changes in the gene pool, such as genetic drift and isolation of sub-populations.

STANDARD 6—HUMAN ANATOMY THE STUDENT WILL DEMONSTRATE AN UNDERSTANDING OF THE COORDINATED STRUCTURES AND FUNCTIONS OF ORGAN SYSTEMS THAT RESULT IN THE RELATIVE STABILITY OF THE INTERNAL ENVIRONMENT OF THE HUMAN BODY, DESPITE CHANGES IN THE OUTSIDE ENVIRONMENT.

6.1 Explain how the complementary activity of major body systems provides cells with oxygen and nutrients and removes toxic waste products such as carbon dioxide.

6.2 Explain how the nervous system (brain, spinal cord, sensory neurons, motor neurons) mediates communication among different parts of the body and mediates the body’s interactions with the environment. Identify the basic unit of the nervous system, the neuron, and explain generally how it worksthe role of neurons in transmitting electrochemical impulsesthe roles of sensory neurons, interneurons, and motor neurons in sensation, thought, and response

6.3 Explain how feedback loops in the nervous and endocrine systems regulate conditions in the body.

6.4Explain the individual functions and sites of secretion of digestive enzymes (amylases, proteases, nucleases, and lipases), stomach acid, and bile salts.

6.6 Explain the cellular and molecular basis of muscle contraction, including the roles of actin, myosin, Ca+2, and ATP.

6.7 Explain how hormones (including digestive, reproductive, and osmoregulatory) provide internal feedback mechanisms for homeostasis at the cellular level and in whole organisms

6.8 Explain the role of the skin and of antibodies in the body's response to infection. 6.9 Explain how vaccination protects an individual from infectious diseases. 6.10 Compare and contrast bacteria and viruses with respect to their requirements for growth
