Explain how the various abiotic factors may affect plants

-
Temperature;  affects  soil  formation  and  distribution  of  plants;  affect  transpiration  rate  as  high temperatures  lead  to  high  rates  of  transpiration;  It  also  affects  the  rate  of  photosynthesis  with the  direct  influence  on  enzyme  activity;  Light  intensity;  affects  the  rate  of  photosynthesis; Wind;  increase  the  transpiration  rates;  affects  dispersal  of  seeds  and  fruits;  agents  of pollination;  affect  distribution  in  terms  of  wind  storms/breakages;  Atmospheric  pressure;  high atmospheric  pressure  leads  to  low  rates  of  transpiration;  high  oxygen  and  carbon  (IV)  oxide concentration;  high  photosynthetic  rates;  while  low  atmospheric  pressure  leads  to  high transpiration  rates;  less  concentration  of  oxygen  and  carbon  (IV)  oxide;  leading  to  low  rates  of photosynthesis;  Water/Rainfall;  forms  a  raw  material  for  photosynthesis;  helps  in  support  in plant  tissues;  affects  distribution  of  plants;  Humidity;  low  humidity  leads  to  high  transpiration rates;  while  high  humidity  leads  to  low  rates  of  transpiration;  pH;  affects  distribution  of  plants; some  grow  in  acidic  soils;  others  in  alkaline  soils;  Edaphic/soil  factors;  affects  plant distribution;  in  terms  of  being  sources  of  water  and  mineral  salts;  provide  a  substratum  for anchorage  of  plants;  Max.  20  mks

DESCRIBE THE ADAPTATIONS OF THE ILEUM TO ITS FUNCTION (20 MARKS)

-
Has secretory glands/crypts of lieberkuhn which secretes enzymes (maltase/sucrase/lactase/peptidase/lipase to complete digestion of sugars/proteins/lipids. Goblet cells secrete mucus which allows for smooth movement of food and protect wall of ileum from action of digestive enzymes Very long to provide large surface area for absorption. Highly folded/coiled to slow movement of food to allow more time for digestion/absorption/ and to increase surface area for absorption. Has numerous villi which increase surface area for absorption/microvilli which further increase surface area for absorption. Ileum wall/villi have thin epithelium which is only one cell thick to reduce distance over which digested food has to diffuse. Villi are highly vascularised/have a rich network of blood capillaries for rapid transport from small intestines and maintain a steep concentration gradient for rapid absorption. Villi have lacteals for absorption of fatty acids and glycerol Cells of ileum wall h...

Explain how structures of the human ear are adapted to their functions. (20 marks)

Image
The pinna;- is funnel shaped to trap sound waves; cartilaginous to maintain the funnel shape; collects and directs sound waves into the external auditory meatus ear; The external auditory canal; - a tube connected to the pinna that directs sound waves from the pinna to the eardrum lining the auditory canal; has hair that trap foreign particles; The canal contains wax-secreting cells; and hair which traps dust particles; and pathogenic bacteria hence prevent them from getting into the ear; The eardrum; - has a thin tough membrane; that easily vibrates when hit by sound waves; transferring them into vibrations. The ear ossiscles; - they act like a layer and they easily move forward and backward to amplify sound vibrations that hit them; The suspensory ligaments; - suspends the ear ossicles and prevents excessive vibration that would otherwise damage the inner parts of the ear; The eustachian tube - it connects the middle ear with the pharynx; and it equalises air pressure between...

KCSE 2010 Q8. Describe how a finned fish such as Tilapia moves in water. (20 marks)

-
The following describes how  a finned fish such as Tilapia moves in water . v       Water is denser than air. The density of water supports fish and provides a medium in which it swims. v       It has a streamlined body; reducing resistance, thus easily swims in the water. v       The scales overlap pointing backwards allowing water to pass over the fish without obstruction. Mucus is also secreted over the scales reducing friction during movement. v       They have a flexible backbone onto which segments of muscle blocks, myotomes, are attached. The muscles contract and relax bringing about undulating movements. v       The fish have fins that help in steering and balancing fish during swimming. v       The pectoral and pelvic fins are paired. They are used for braking, steering and v   ...
