CSEC Biology and HSB Notes

SYLLABUS REFERENCE [B5.5] explain the concept of homeostasis;  [B5.6] explain the concept of feedback mechanisms;  [B5.7] discuss the regulation of blood sugar;  [B5.9] distinguish between heat and temperature;  [B5.10] discuss the regulation of temperature; 

SYLLABUS REFERENCE  CSEC HSB [B6.9] relate the internal structures of the eye to their functions;  [B6.10] explain how images are formed in the eye;  [B6.11] explain accommodation in the eye;  [B6.12] discuss the causes of, and corrective measures for eye defects and diseases.  CSEC Biology  [B7.9] relate the structure of the human eye to its functions as a sense organ;  [B7.10] explain accommodation; sight defects and the corrections of each; 

SYLLABUS REFERENCE  CSEC HSB [B6.1] describe the main divisions of the nervous system;  [B6.2] distinguish between a neuron and a nerve;  [B6.3] explain the functions of motor and sensory neurons and spinal synapses;  [B6.4] describe the functions of the parts of the brain;  [B6.5] describe the mechanisms of a reflex action;  [B6.6] explain the process by which voluntary actions occur;  [B6.7] distinguish between a voluntary and involuntary action;  [B6.8] explain the response of the sense organs to stimuli;  [B6.13] compare and contrast endocrine and nervous control systems;   [B6.14] identify the sites of hormone production;   [B6.15] explain the roles of selected hormones in the human body;  CSEC Biology  [B7.1] define 'stimulus' and 'response';  [B7.2] describe the response of: (a) green plants to stimuli; (b) invertebrates to variations in light intensity, temperature and moisture;  [B7.3] define r...
