*BIOLOGY ANSWERS*
(5ai)
(PICK ANY ONE)
Competition is the process by which living organisms in a habitat struggle or compete with one another for limited essential needs such as food, light, nutrients, shelter or space in the environment.
OR
Competition is an interaction between organisms or species in which both the organisms or species are harmed. It arises when individuals or populations vie for the same resource (such as food, water, space, shelter, mate, ecological status, etc.) that is in limited supply.
(5aii)
(i) Intraspecific competition
(ii) Interspecific competition
(5aiii)
(PICK ANY FOUR)
(i) Food
(ii) Water
(iii) Shelter
(iv) Space
(v) Sunlight
(vi) Nutrients
(5aiv)
(PICK ANY ONE)
During succession, early pioneer species colonize an area with little competition due to harsh conditions. As the ecosystem matures, resources increase, leading to heightened competition among species. This competition drives the succession process, as more competitive species outcompete and replace earlier ones, resulting in a progressively more diverse and stable ecosystem over time.
OR
Competition and succession are linked in ecosystems. Early in succession, pioneer species face little competition. As ecosystems develop, resources increase, and competition among species intensifies. This drives succession, with more competitive species replacing earlier ones, leading to a stable and mature ecosystem.
(5bi)
(PICK ANY ONE)
Structural adaptation refers to physical features of an organism that enhance its ability to survive and reproduce in its specific environment. These adaptations involve the organism's body structure, such as shape, size, and special body parts, that help it to survive in its habitat.
OR
Structural adaptations refer to the changes in the structure of a living organism that enables it to adapt better to its environment. These adaptation consist of special body parts, such as skin, color, and shape.
(5bii)
(i) Camouflage
(ii) Mimicry
(iii) Body Coverings and parts
(iv) Specialized limbs and appendages
(5c)
(PICK ANY FOUR)
(i) Fingerprints
(ii) Facial Recognition
(iii) DNA Profiling
(iv) Retinal Scans
(v) Voice Recognition
(5d)
(PICK ANY THREE)
Adaptive coloration | Example
(i) Camouflage | Chameleon
(ii) Disruptive Coloration | Zebra
(iii) Warning Coloration | Poison dart frog
(iv) Mimicry | Viceroy Butterfly
(v) Countershading | Great White Shark
(5e)
(PICK ANY THREE)
(i) Rubber Tree
(ii) Pitcher Plants
(iii) Giant Water Lilies
(iv) Banana Trees
(v) Orchids
(vi) Bromeliads
(vii) Ferns
*NOTE: BOTH IMAGE AND TYPED ONE IS CORRECT... CHOOSE EITHER IMAGE OR TYPED ONE*
*SECOND VERSION*
*BIOLOGY ANSWERS*
(1ai)
Glomerulus:
(PICK ANY ONE)
(i) It filters blood to form glomerular filtrate.
(ii) It removes waste products and excess substances from the bloodstream.
(iii) It initiates the urine formation process by allowing water and small molecules to pass through while retaining larger molecules like proteins.
(1aii)
Bowman's capsule:
(PICK ANY ONE)
(i) It collects the filtrate produced by the glomerulus.
(ii) It forms primary urine by capturing the filtrate and directing it into the nephron.
(iii) It serves as a funnel, guiding the filtrate into the proximal convoluted tubule for further processing.
(1aiii)
Proximal convoluted tubule:
(PICK ANY ONE)
(i) It reabsorbs water, ions, and nutrients from the filtrate back into the bloodstream.
(ii) It plays a crucial role in secreting waste products such as hydrogen ions and ammonia into the tubular fluid.
(iii) It maintains pH balance by selectively reabsorbing bicarbonate ions and secreting hydrogen ions.
(1aiv)
Distal convoluted tubule:
(PICK ANY ONE)
(i) It reabsorbs sodium and water, thus playing a key role in regulating blood pressure and fluid balance.
(ii) It secretes potassium and hydrogen ions, which helps in maintaining electrolyte and acid-base balance.
(iii) It also regulates calcium and phosphate levels in the blood, contributing to bone health and metabolic functions.
