Answer:
Option (1).
Explanation:
Acanthamoeba infection may be defined as the eye infection that may cause permanent loss of vision in serious infection. This infection may cause blurred vision with redness of eye.
Acanthamoeba is a microscopic organism that are mainly found in water, lake, soil and swimming pool. Hence, swimming in lake while wearing contact lenses can easily cause Acanthamoeba infection.
Thus, the correct answer is option (1).
1. The non-native species are considered to be invasive only when they cause harm. Some of the features that increase the possibility of a non-native species in becoming an invasive species are they reproduce easily, they are habitat generalist, they out-competes other plant species, possesses the tendency to produce abundant seeds, and are not influenced by the native diseases and pests.
2. If an ecosystem were identical to the local ecosystem of a species, it would possibly be easier for the species to invade. For example, if the species is found in a novel location, which is the identical biome as its local ecosystem, then it is probably more common to turn into an invasive species.
3. The introduction of a non-native species to monitor the invasive species does not always work. However, even if it works, the other native species could also get influenced adversely. If the population of the introduced species enhances too much, it can result in competition for space and food with the native species. The non-native species may also result in the introduction of diseases, which might kill or harm the local species.
Answer:
a. whale and tuna
b. pig and chicken
c. tuna and fly
Explanation:
Following, you will find characteristics of each species that differ in the contrasting groups. These descriptions reflect the divergence degree between groups.
a. whale and tuna
- Whales: Vertebrate and Big-sized marine mammals. They are long-lived and pulmonate animals. They are relatively slow, and only breathe while they are on the surface, opening the blowhole which covers the narines. Despite being mammals, they lack hair, so they have naked soft skin. They have one dorsal fin, two lateral flippers, and a caudal horizontal fin, which they move up and down. They are viviparous, with internal fecundation, and females carry mammal glands to feed their offspring. They feed on krill and other small animals, which they filtrate using their baleens. Whales exhibit the Type I survivorship curve. Mortality often occurs at the end of the cycle. They have long cycles of life and high probabilities to survive until they are old enough. These species have few descendants and spend too much time and energy in parental care to ensure their reproductive success. They are used to swim deep depth or near the surface depending on the reproductive cycle stage.
- Tuna: Bony marine fish. Fusiform and medium-sized body, fast swimmers. They can live for 15 years. Their body is covered with scams. They have two dorsal fins, two ventral fins, two lateral fins, and a caudal fin which they move from side to side. It swims near the surface and interchange gas using the grills. They have many teeth and feed on anything they can, such as small fishes, zooplankton, crustaceans, and mollusks. They have external fecundation and exhibit the Type III survivorship curve. Significant mortality during the early stages of life. Only a few individuals reach the later life stages, getting to survive their first period of life. Survivors usually have a long life. These species produce big offsprings at the same time, but they provide little or no parental care. Their reproductive success relies on the number of descendants.
b. pig and chicken
- Pigs: Heary Mammal, with thick hairs, called bristles and mammal glands. They are four-legged, have hooves and four fingers. Their snout is long and flexible, with sharp teeth. They have a curly tail and thick and sensitive skin. Naturally, they are herbivorous but became omnivorous in captivity. They can live for ten or fifteen years. Viviparous. Well-developed smell sense and no sudoriparous glands. Territorial, dominant, and highly communicative with partners. They can use more than twenty different sounds. They also exhibit the Type I survivorship curve.
- Chickens: Birds. They have two legs and two wings however, it has never been successful in flying. Their body is cover by feathers. They have no hair, and they do not have teeth either, but they have a corneous peak instead. They are omnivorous. They show sexual dimorphism, especially in feathers and crests. They exhibit the type II survivorship curve. The probabilities of dying are equals all along the cycle, at any age interval. The number of dead individuals remains constant from the beginning to the end of the life cycle. These species have reduced offsprings, and they ensure their reproductive success by providing some significant parental care.
c. tuna and fly
- Tuna: Already described above
- Fly: Flying and small-sized Insects. Dipterous, with their bodies divided into three regions: Head, thorax, and abdomen. They have six appendixes to walk, one pair of wee-developed wings, one pair of vestigial wings, eyes very sensitive to light. The mouthparts are used to lick, suck or bite. Some species can sting and suck blood from humans. Their body is covered with thin hairs and sensory bristles used to taste, feel, and smell. They are attracted by smelly matter, from which they feed on. In general, flies are associated to matter in decomposition and wastes. They have a short life cycle and can live up to twenty-five days. Ovoviviparous species, laying too many eggs that will turn into larvae and finally to the adult fly stage.
B. Air pollution that's right because the poisonous fumes going into the air
