Explain why significantly increasing the blood pH slows down the rate of selective reabsorption of materials in the kidney tubules.

Picture
answers
  • selective reabsorption of materials in the kidney tubules  is energy dependent/require energy ; synthesized through the process of (cellular) respiration/action of respiratory enzymes; whose working (effectiveness)is affected by change in pH/are denatured at high pH; pH affects the working / permeability of the (kidney tubule cells)membrane;

The diagram below illustrates a section of the mammalian kidney.
Picture
​(a) Name the structures labelled E and F.
E 
F
(b) Explain the processes that take place in the regions labelled G and H.
Region G 
Region H 
answers
​ (a) E—Glomerulus; 
F — Interlobular artery/branch of renal artery;
(b) Region G 
At the (glomerulus), the afferent arteriole which brings blood to the glomerulus is wider than the efferent arteriole; this creates high pressure; leading to ultrafiltration; At the proximal convoluted tubule /distal convoluted tubule, substances required by the body/amino acid substances required by the body (amino acids/glucose/vitamins! some water; are selectively re-absorbed (into the blood stream); hence selective reabsorption;
Region H
At the descending arm of/limb of the Loop of Henle, water is selectively reabsorbed; At the ascending arm/limb of the Loop of Henle, sodium ions/salts are actively/selectively reabsorbed; At the collecting duct, water is (selectively) reabsorbed:

Below is a graphical representation of how basal metabolic rates compare in Various animals.
Picture
​From the graph, explain why the mouse has a higher breathing rate than the elephant.
answers
  •  Mouse is active/has a large surface area to volume ratio; hence has a higher metabolic rate (rate of breathing) to cope with the rate at which energy (oxygen) is consumed or lost to the environment; an elephant is less active/has a small surface area to volume ratio hence has a lower rate at which energy (oxygen) is used or lost; or 
  • Mouse is small in size/has large surface area to volume ratio; hence has a metabolic rate (rate of breathing) to cope with the rate at which oxygen is consumed/energy ¡s lost to the environment; an elephant is large in size/has small surface area to volume ratio; hence has a lower rate at which oxygen/energy is lost;

K.C.S.E Biology Q & A - MODEL 2018PP1QN24

Explain why a camel has a longer nephron than a whale.

Picture
answers
  • A camel is a desert animal, a longer nephron increases the surface area for reabsorption of water; to conserve it; a whale is aquatic animal (codes not need to conserve water)

K.C.S.E Biology Q & A - MODEL 2014PP2QN08

Describe the role of the human skin in homeostasis.

Picture
answers
When body temperature is lowered below normal; arterioles in the skin constrict; blood is diverted to a shunt system; less blood flows to the skin/less heat is lost; when body temperature is raised above normal;arterioles in the skin dilate;more blood flows to the skin; more heat is lost by convection and radiation;when body temperature is lowered below normal:erector-pilli muscle s contract, hair stands erect; more air is trapped, air is a bad conductor;and insulates the body against heat loss; when body temperature is raised above normal: erectorpi11i muscles relax, hair lies on skin;less air is trapped, more heat is lost; when body temperature is lowered below normal: less fluids are absorbed by sweat glands;less sweating, less vaporisation of water;
when body temperature is raised above normal:sweat glands are more stimulated and more sweat is produced; water in sweat evaporates and takes up heat from the body;body is cooled/body temperature is lowered;
