The gray squirrel, Eastern fox squirrel, and red squirrel are all different species of squirrels. Why is having a scientific name for each species of an organism important?
A team of students encounters an unknown organism in a field while conducting a biodiversity study. Some students think the organism is a plant, while others think it is a fungus. Which question should the students investigate to classify the organism correctly?
Which list correctly identifies characteristics that protists share with animals?
Four common relationships between organisms are listed in the box.
Which statements best describe these relationships?
The acacia ant (Pseudomyrmex ferruginea) lives in the bulls horn acacia plant, as shown below
The acacia ant nests and feeds in the plant’s hollow thorns. The ant helps protect the bullshorn acacia by attacking insects and grazing animals that come near the plant. The relationship between the acacia ant and the bullshorn acacia is an example of which of the following?
A remora is a fish that has an adhesive disk on the back of its head that it uses to attach itself to a large shark. When food floats away from the shark’s mouth as it feeds, the remora collects the scraps. Drawings of a shark with a remora attached and a remora’s adhesive disk are shown below
The relationship between the remora and the shark is an example of —
Using a light microscope, a student identified the following characteristics of four organisms found in a sample of pond water.
Based on the observations of the student, which organisms most likely belong to the taxonomic group for bacteria?
Bats eat insects that damage crops and mosquitoes that are vectors for disease. One million bats can eat several tons of insects per night, saving billions of dollars in pesticides yearly. Agricultural and public health scientists are concerned about the spread of white-nose syndrome (WNS). WNS is a result of a fungus that can infect cave-dwelling bats. While bats hibernate during winter months, the fungus covers the bats’ face and wings. WNS has a near 100% mortality rate, and 5.7 million bats have died since the discovery of the fungus in 2006. Many scientists are searching for ways to protect these bats. The relationship between this fungus and bats can best be defined as —
A group of students used this diagram to classify three organisms into different kingdoms.
Which table correctly identifies the three kingdoms?
The ocean sunfish (Molamola) is a large, flat fish that spends most of its time in deep water feeding mainly on jellyfish. Sunfish often have many species of copepods, small crustaceans that bury their heads into the soft tissue of the sunfish. Sunfish will swim to the surface of the water and lie sideways, allowing seabirds to eat the copepods from their skin.
Which list describes the types of relationships the sunfish has with other marine organisms?
