Ch. 5 – Sensory‚ Attentional and Perceptual Processes 1 Explain the functional limitations of sense organs. Ans. Our sense organs function with certain limitations. E.g. our eyes cannot see things which are very bright or dim. Our senses function within a limited range of stimulation. In order to be noticed by the sensory receptor‚ a stimulus needs to be of a suitable intensity to be noticed by the sensory receptor‚ i.e. it has to carry a minimum value or weight. The minimum value of a stimulus

factors is slowing down the rate of enzyme reactions‚ it depends on the concentration of those factors. Since enzymes are catalyst of chemical reactions‚ they are responsible to the activities of cells‚ and they determine the function of tissues and organs as well. In plant cells‚ during photosynthesis‚ enzymes are used in chloroplast to catalyse the processes. In light-dependent stage‚ ATP synthase enzyme is used to generate ATP molecules‚ they can be used in light-independent stage. Another enzyme

10/21/14 Nervous system: one of the eleven major body organ systems in animals; coordinates and controls actions of internal organs and body systems; receives and processes sensory information from external environment; coordinated short-term reactions to these stimuli. Cell body: the part that contains the nucleus and most of the cytoplasm and the organelles. Axon: sends messages away from the cell body to other neurons. Dendrite: short‚ highly branched fibers that carry signals toward the cell

DESIGN ANALYSIS A. Determination of the capacity of the Hopper The hopper is a truncated square pyramid which serves as the input unit‚ so it was designed to provide smooth supply of moringa leaves into the pulverizing chamber. Considering AMB‚ EMAM=h260+h 30160=h260+h h=60mm therefore the total height H=60+260=320mm. Volume of hopper=volume of large pyramid – volume of small pyramid Volume of pyramid=1/3[a2H- b2h] Where a=320mm‚ b=60mm Volume = 1/3[(3202x320)- (602)(60)] = 10850667mm3

There are many ways in which substances can move across the cell membrane and in which then helps in the function of the body (cells‚ tissues and organs) overall. There are 3 processes that a substance can move across the membrane‚ theses are diffusion (simple and facilitated)‚ osmosis and active transport. Both diffusion and osmosis are passive processes‚ which mean they do not need energy to occur‚ whereas active transport does require energy. All three processes are involved in many functions

The digestive system is very important to the body. Without it‚ we would not be able to live. It is a series of hollow organs joined in a long‚ twisting tube from the mouth to the anus.
