The other statements are generally true for nematodes. 3 / 50 3. what is the goal of color adaptation A) to escape predator B) to attract prey C) to prevent water loss D) to attract mating partner Color adaptation often serves to camouflage organisms, helping them avoid predation. 4 / 50 4. what is the function of contractile vacuole in paramecium A) for absorbing oxygen B) for mobility C) for absorbing nutrients D) for expelling excess water The contractile vacuole functions to expel excess water that accumulates in the cell, maintaining osmotic balance. 5 / 50 5. which of the following is not correct A) birds that feed on fish have long pointed beaks B) birds that feed on nectar have long slender beak C) birds that feed on grains have long wide beaks D) birds that hunt preys have curved strong beak Birds that feed on grains typically have stout, short beaks suitable for cracking seeds, not long wide beaks. 6 / 50 6. which of the following is not corect about tapeworm A) it has mouth and well developed intestinal tract B) each proglottides has a reproductive system C) the head has a scolex D) it has segments called proglottides Tapeworms lack a mouth and digestive tract; they absorb nutrients directly through their skin. 7 / 50 7. which of the following is not an effect of noise pollution A) headache B) blindness C) poor sleep D) high blood pressure Noise pollution can lead to various health issues such as poor sleep, headaches, and high blood pressure, but it does not cause blindness. 8 / 50 8. which of the following is not correct about mesophytes A) the have poorly developed roots B) they have large leaves C) they have waxy cuticle D) they live on land with just enough water Mesophytes, which thrive in environments with moderate water availability, typically have well-developed roots to access moisture. 9 / 50 9. which of the following is not a cause of water pollution A) dredging B) crude oil drilling C) fishing D) agricultural waste Fishing itself does not directly cause water pollution. In contrast, crude oil drilling, dredging, and agricultural waste are activities that can lead to water contamination. 10 / 50 10. which of the following is not caused by food shortage A) canibalism B) competition C) migration D) increase natality An increase in natality (birth rate) typically occurs when resources are plentiful, not during food shortages. Food shortages can lead to competition, cannibalism, and migration, but not to increased birth rates. 11 / 50 11. which of the following is not present in tapeworm A) circulatory system B) reproductive system C) nervous system D) respiratory tube Tapeworms do not have a respiratory system; they exchange gases through their body surface 12 / 50 12. which of the following is the correct order of food chain A) grass, grasshopper, toad, snake, hawk B) grasshopper, agama lizard, hawk, snake C) grass, lion, antelope, man D) grass, grasshopper, snake, fowl This sequence represents a correct food chain, starting from a primary producer (grass) to primary consumers (grasshoppers), and then moving up to secondary consumers (toads), tertiary consumers (snakes), and finally quaternary consumers (hawks). 13 / 50 13. which of the following worms is transmitted by mosquito A) round worm B) pin worm C) filarial worm D) tapeworm Filarial worms are transmitted by mosquito bites, causing diseases like lymphatic filariasis, whereas the other worms listed do not have mosquito vectors. 14 / 50 14. which of the following is not caused by tapeworm A) rickets B) indigestion C) anemia D) malnutrition Rickets is primarily caused by a deficiency of vitamin D, calcium, or phosphate, not by tapeworm infection. The other conditions (anemia, malnutrition, indigestion) can be related to parasitic infections. 15 / 50 15. which of the following is caused by blackfly A) River blindness B) night blindness C) elephantiasis D) anemia River blindness (onchocerciasis) is caused by the filarial worm transmitted by blackflies. 16 / 50 16. which of the following causes acid rain A) neon B) hydrocarbon C) carbondioxide D) oxide of Nitrogen Oxides of nitrogen also contribute to acid rain, reacting with water to form nitric acid. 17 / 50 17. which of the following is not a mutualistic relationship A) rhizobium and leguminous plant root B) flatworm and intestine of man C) epiphyte and tall trees D) cattle and cattle egret The relationship between flatworms and the human intestine is parasitic.

Which of the following is not a parasitic adaptation of tapeworm A) hermaphrodite nature B) ability to live in the absence of oxygen in the intestine C) ability to make use of established food chain(from grass to cow and to man) D) ability to produce few tiny eggs This refers to a food chain, not an adaptation of the tapeworm itself. Tapeworms exploit hosts for nutrients rather than utilizing the food chain. 20 / 50 20. which of the following is not an effect of noise pollution A) malnutrition B) restlessness C) deafness D) headache Noise pollution primarily affects health and well-being, leading to issues like deafness, restlessness, and headaches, but it does not directly cause malnutrition. 21 / 50 21. which of the folowing is not corect about xerophytes A) they have broad leaves B) they have long deep roots C) they have succulent D) they live in desert Xerophytes typically have narrow or reduced leaves to minimize water loss, not broad leaves. 22 / 50 22. which of the following is not a common cause of water pollution A) household wastes B) agricultural waste C) nuclear waste D) industrial waste While nuclear waste can contaminate water, it is not as common as agricultural waste, household wastes, or industrial waste, which frequently contribute to water pollution. 23 / 50 23. which of the following is not correct A) the body fluid of fresh water organism are more concentrated than the surround fresh water B) the vacuole of amoeba is for osmoregulation C) the cuticle of plant is an adaptation to prevent water loss D) large acquatic animals have well developed support system than terrestial animals Large aquatic animals typically have buoyancy support from water, reducing the need for a robust skeletal structure compared to terrestrial animals, which require strong support systems against gravity. 24 / 50 24. which of the following is not correct about the relationship between rhizobium and leguminous plants A) rhizobium fixes nitrogen in the soil to nourish the plant B) it is mutualistic C) rhizobium causes blighting of the plant leaves D) the plant root provide organic nutrients(sugar and nutrients) for rhizobium This statement is incorrect; rhizobia form a mutualistic relationship with leguminous plants, fixing nitrogen and providing benefits rather than causing harm. 25 / 50 25. Which of the following is not correct about the proglottis of tapeworm A) a new proglottis is formed near the head or scolex B) A proglottis is a single segment of the tapeworm C) each segment has stomach and intestine for feeding D) each proglottis has male(testis) and female organ(ovary) for hermaphroditic reproduction Proglottids do not have a digestive system; they absorb nutrients through their body surface. 26 / 50 26. Which of the following is not a parasitic adaptation A) ability to moult B) ability to burrow or penetrate tissue C) ability to produce enzymes that dissolve tissue D) ability to cling The ability to moult is a general adaptation seen in many organisms for growth and development, not specifically a parasitic adaptation. The other options directly relate to adaptations that help parasites survive in their hosts. 27 / 50 27. which of the following is not a adaptation for acquatic life A) development of gills B) steamlined body structure C) development of tail D) long neck A long neck is not a typical adaptation for aquatic life.

Preventing overgrazing and deforestation, as well as crop rotation, are effective strategies for preventing soil pollution. 30 / 50 30. which of the following is not a way of clearing crude oil pollution of water A) using chemical dispersants B) growing oil eating bacteria C) dredging D) using adsorbents to remove the oil Dredging is used to remove sediment and debris from the bottom of water bodies, but it is not effective for clearing crude oil. The other methods (using adsorbents, growing oil-eating bacteria, and using chemical dispersants) are specifically designed to address oil pollution. 31 / 50 31. Which of the following is not correct about a tapeworm (Taenia ) A) tapeworm interact with man in a symbiotic behavior B) tapeworm has a knoblike head called scolex C) tapeworm feed by diffusion through body surface D) tape worm has no alimentary canal Tapeworms are typically parasitic and cause harm to their hosts rather than providing mutual benefits, which is what symbiosis implies 32 / 50 32. which of the following least affects population size A) variation B) abiotic factor C) immigration D) disease Variation refers to genetic diversity within a population and does not directly affect population size like disease, immigration, or abiotic factors do. 33 / 50 33. which of the following causes soil pollution A) plantign trees B) dumping of garbage C) dredging D) Using pesticides The use of pesticides contributes to soil pollution through chemical residues that can harm soil health. Dredging and dumping of garbage can also cause pollution, but planting trees helps improve soil quality. 34 / 50 34. Which of the following is not correct A) the part of water plant below the water level have thin cuticle B) hydrophytes have less developed roots compared to terrestrial plants C) water plants have air spaces for holding oxygen D) hydrophytes have well developed conducting system to transport water Hydrophytes often have less developed conducting systems compared to terrestrial plants because they live in water, where water is readily available. 35 / 50 35. which of the following is not correct about smog A) smoke damages lungs , eyes and nose B) it occurs in small undeveloped cities C) it is a combination of smoke, chemical polutant and water droplet D) smoke damages vegetations Smog typically occurs in large, industrialized cities due to high levels of pollution, not primarily in small or undeveloped areas. 36 / 50 36. which of the following is the function of the ozone layer A) prevent lightening B) prevent excess irradiation from the earth C) prevent sandstorm D) prevent flooding The ozone layer protects the Earth by absorbing the majority of the sun's harmful ultraviolet (UV) radiation, preventing excessive irradiation. 37 / 50 37. which of the following least affects population size A) water supply B) food availability C) countershading D) disease Countershading is a form of camouflage that helps animals avoid predation, but it does not directly influence population size. In contrast, food availability, disease, and water supply are critical factors that can significantly impact population dynamics. 38 / 50 38. a density factor that regulates the population of organisms in an area is A) fire outbreak B) disease outbreak C) drought D) flood Disease can significantly affect population density by increasing mortality rates, unlike factors like flood or drought, which can cause temporary changes. 39 / 50 39. which of the following is not correct A) symbiosis is relationship in which both parties benefit B) parasitisim is relationship in which one party benefits C) mutalism is relationship in which both parties benefit D) commensalism is relationship in which no party benefits Commensalism is actually a relationship where one party benefits while the other is neither 40 / 50 40. dumping pile of sewage and garbage on land is A) air pollution B) soil pollution C) land pollution D) environmental pollution The act of dumping sewage and garbage on land results in land pollution, which negatively impacts soil and the surrounding environment. 41 / 50 41. which of the following is not correct about adaptation in plants A) they have roots for absorbing water B) the have waxy leaves for preventing water loss C) they have stomata for absorbing oxygen D) the have swollen stem for water storage Stomata are primarily for gas exchange, allowing for the uptake of carbon dioxide and the release of oxygen, not for absorbing oxygen directly. 42 / 50 42. which of the following causes acid rain A) hydrocarbon B) oxygen C) carbondioxide D) sulphur dioxide Sulphur dioxide is a primary contributor to acid rain, as it reacts with water in the atmosphere to form sulfuric acid. 43 / 50 43. which of the following is systems is absent in a tapeworm A) circulatory system B) reproductive system C) alimentary system D) nervous system Tapeworms do not have a circulatory system; they rely on diffusion for nutrient and gas exchange. They also lack an alimentary system 44 / 50 44. A plant that grows on another plant without harming the host is A) saprophyte B) epiphyte C) thallophyte D) ectoparsite Epiphytes live on other plants but do not harm them, unlike parasites, which take nutrients from the host. 45 / 50 45. which of the following is water storage structure in plants A) succulent B) stomata C) cuticle D) xylem Succulents are specialized plant structures that store water, allowing plants to survive in dry conditions. 46 / 50 46. Which of the following is not faced with the uncertainty of hunting for food A) snake B) hyena C) hawk D) goat Goats are herbivores that graze on plants, and they have a predictable food source. In contrast, hyenas, snakes, and hawks rely on hunting, which involves uncertainty in finding prey. 47 / 50 47. which of the following is not a way of preventing soil pollution A) crop rotation B) manuring and prevening over grazing C) proper waste disposal D) preventing soil erosion Proper waste disposal is a general practice for managing waste, but it is not specifically a method for preventing soil pollution compared to crop rotation, manuring, and preventing overgrazing. 48 / 50 48. which of the following is not correct about nematodes A) they are roundworms B) the have separate male and female C) they feed by diffusion D) they have nervous system Nematodes have a complete digestive system and do not rely on diffusion for feeding. They actively ingest food. 49 / 50 49. Which of the following is not a parasitic adaptation A) presence of hook B) presence of haustorium or sucker C) hermaphrodite nature D) presence of nephridium Nephridia are excretory organs found in some invertebrates, not specifically adaptations for parasitism. The other options (haustorium, hook) are adaptations that assist in attachment and nutrient absorption 50 / 50 50. which of the following is not correct about tapeworm A) it is flat or plathyhelminth B) it is hermaphrodite C) it feeds by diffusion D) it has a hook for digging soil Tapeworms do not have hooks for digging; they have hooks or suckers for attachment to the host's intestinal wall.
