Adaptations like gills, streamlined bodies, and a development of tails are common in aquatic organisms. 8 / 50 8. A plant that grows on another plant without harming the host is A) thallophyte B) epiphyte C) ectoparsite D) saprophyte Epiphytes live on other plants but do not harm them, unlike parasites, which take nutrients from the host. 9 / 50 9. Which of the following is not faced with the uncertainty of hunting for food A) snake B) goat C) hawk D) hyena 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. 10 / 50 10. a density factor that regulates the population of organisms in an area is A) disease outbreak B) fire outbreak C) flood D) drought Disease can significantly affect population density by increasing mortality rates, unlike factors like flood or drought, which can cause temporary changes. 11 / 50 11. Which of the following is not correct about a tapeworm (Taenia ) A) tapeworm feed by diffusion through body surface B) tape worm has no alimentary canal C) tapeworm interact with man in a symbiotic behavior D) tapeworm has a knoblike head called scolex Tapeworms are typically parasitic and cause harm to their hosts rather than providing mutual benefits, which is what symbiosis implies 12 / 50 12. which of the following is not correct about nematodes A) they feed by diffusion B) they are roundworms C) the have separate male and female D) they have nervous system Nematodes have a complete digestive system and do not rely on diffusion for feeding. They actively ingest food. 13 / 50 13. dumping pile of sewage and garbage on land is A) air pollution B) environmental pollution C) soil pollution D) land pollution The act of dumping sewage and garbage on land results in land pollution, which negatively impacts soil and the surrounding environment. 14 / 50 14. which of the following is systems is absent in a tapeworm A) nervous system B) alimentary system C) reproductive system D) circulatory system Tapeworms do not have a circulatory system; they rely on diffusion for nutrient and gas exchange.

Which of the following is not a parasitic adaptation A) hermaphrodite nature B) presence of hook C) presence of nephridium D) presence of haustorium or sucker 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 41 / 50 41. which of the following causes soil pollution A) dumping of garbage B) dredging C) Using pesticides D) plantign trees 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. 42 / 50 42. which of the following is not present in tapeworm A) reproductive system B) circulatory system C) nervous system D) respiratory tube Tapeworms do not have a respiratory system; they exchange gases through their body surface 43 / 50 43. which of the following is the function of the ozone layer A) prevent flooding B) prevent excess irradiation from the earth C) prevent lightening D) prevent sandstorm The ozone layer protects the Earth by absorbing the majority of the sun's harmful ultraviolet (UV) radiation, preventing excessive irradiation. 44 / 50 44. which of the following least affects population size A) water supply B) disease C) food availability D) countershading 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. 45 / 50 45. 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) the plant root provide organic nutrients(sugar and nutrients) for rhizobium C) rhizobium causes blighting of the plant leaves D) it is mutualistic This statement is incorrect; rhizobia form a mutualistic relationship with leguminous plants, fixing nitrogen and providing benefits rather than causing harm. 46 / 50 46. which of the following is not caused by tapeworm A) rickets B) anemia C) malnutrition D) indigestion 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. 47 / 50 47. which of the following is not correct about smog A) smoke damages vegetations B) it is a combination of smoke, chemical polutant and water droplet C) it occurs in small undeveloped cities D) smoke damages lungs , eyes and nose Smog typically occurs in large, industrialized cities due to high levels of pollution, not primarily in small or undeveloped areas. 48 / 50 48. 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. 49 / 50 49. which of the following is water storage structure in plants A) stomata B) xylem C) succulent D) cuticle Succulents are specialized plant structures that store water, allowing plants to survive in dry conditions. 50 / 50 50.
