Quiz On Evolution And Classification! Trivia Facts

Early autotrophs had an advantage over early heterotrophs because they were able to produce their own food through processes like photosynthesis. This allowed them to obtain energy directly from the environment, without relying on consuming other organisms. By being able to generate their own food, autotrophs had a more reliable and independent source of energy, giving them a competitive edge over heterotrophs.

A millipede fits the given characteristics as it has many more than 8 jointed legs on a segmented body. It also has 2 pairs of legs attached to each body segment. Additionally, millipedes lack biting jaws, which is another characteristic mentioned. Therefore, the correct answer is millipede.

Early autotrophs had an advantage over early heterotrophs because they were capable of producing their own food through photosynthesis or chemosynthesis. This ability allowed them to utilize energy from the environment and convert it into organic compounds, providing a constant and reliable source of nutrition. In contrast, early heterotrophs were dependent on consuming other organisms for their energy needs, which may have been less efficient and more unpredictable. By being self-sufficient in their food production, early autotrophs had a competitive edge and were able to thrive and reproduce more effectively.

Chimpanzees and gorillas share the most recent common ancestor based on their taxonomic classification. The fact that they belong to the same family indicates that they are more closely related to each other compared to the other pairs of organisms listed. The shared family classification suggests a closer evolutionary relationship, indicating a more recent common ancestor.

Lions, cheetahs, and tigers share the most specific taxonomic level of "Family." This is because they all belong to the same family, Felidae, which is a taxonomic grouping that includes all the big cats. The family level is more specific than the higher levels of Kingdom and Phylum, but less specific than the lower levels of Genus and Species.

The statement "They produce fertile offspring" most likely indicates that the two populations of animals are the same species. This is because the ability to produce fertile offspring is a key characteristic of members of the same species. If two populations can successfully mate and produce offspring that are capable of reproducing, it suggests that they share enough genetic similarity to be considered the same species.

The statement "They produce fertile offspring" most likely indicates that the two populations of animals are the same species because the ability to produce fertile offspring is a key characteristic of a species. If two populations can successfully reproduce and produce offspring that are capable of reproducing themselves, it suggests that they share enough genetic similarity to be considered the same species. The other statements, such as inhabiting the same general area, having similar outward appearance, or consuming the same type of diet, can be indicative of similarity but do not necessarily confirm that the populations are the same species.

The correct answer is "Giraffe necks varied in length, and the shorter-necked giraffes were at a disadvantage." This example best illustrates the process of natural selection because it shows that the variation in neck length among giraffes leads to certain individuals being less suited to their environment. The shorter-necked giraffes are at a disadvantage in reaching food sources, which reduces their chances of survival and reproduction. Over time, this can lead to the longer-necked giraffes being more successful in passing on their genes, resulting in a population with predominantly longer necks.

Viruses require a host cell to reproduce because they are obligate intracellular parasites. They cannot replicate or carry out metabolic processes on their own, so they rely on the machinery and resources of a host cell to complete their life cycle. Once inside a host cell, viruses hijack the cell's machinery to replicate their genetic material and produce new virus particles. This process often damages or destroys the host cell, leading to the release of new viruses that can infect other cells.

The organisms that possess these traits are from the kingdom Plantae. Plantae includes all plants, which are characterized by having eukaryotic cells, being photosynthetic, and having cellulose cell walls.

Biological evolution refers to the change in the genetic makeup of a population over time. This change occurs in the gene pool of a population as new genetic variations arise and are passed on to future generations. The size of individuals, size of a population, and outward appearance of individuals may vary within a population, but these changes do not necessarily represent biological evolution as they do not involve changes in the genetic composition of the population.

In this simulation, the green individuals are more likely to survive and reproduce because they blend in with the green grass, making it harder for predators (represented by the students) to spot and capture them. The red individuals, on the other hand, stand out against the green grass, making them easier targets for the predators. This natural selection process favors the survival and reproduction of the green individuals, leading to a higher likelihood of their population increasing over time.

Larger horses producing a slightly greater number of surviving offspring best explains the increase in the size of horse skeletons over time. This suggests that the larger horses had a reproductive advantage, leading to more successful offspring. As a result, the population gradually shifted towards larger horses, causing an increase in their average size over generations.

A multicellular, nonmotile, autotrophic organism would be classified in the kingdom Plantae. This is because the characteristics mentioned, such as being multicellular and autotrophic, are common traits of plants. Plants are known for being able to produce their own food through photosynthesis and typically have a stationary lifestyle. Therefore, the correct answer is Plantae.

The most likely conclusion about the evolutionary relationship between these organisms is that the wood frog and bullfrog share a more recent common ancestor than the western toad and the spadefoot toad. This conclusion can be drawn because organisms that share a more recent common ancestor are more closely related. Since the wood frog and bullfrog are both in the same genus Rana, while the western toad and spadefoot toad are in different genera, it suggests that the wood frog and bullfrog have a closer evolutionary relationship.

The most accurate conclusion about the relationship of the organisms Homo erectus and Homo neanderthalus is that they are genetically similar. This can be inferred from the fact that they are both classified under the same genus, Homo. The genus classification suggests that they share common ancestry and have significant genetic similarities.

Monerans and protists can be classified as primary producers because they are able to produce their own food through photosynthesis or chemosynthesis. Monerans, such as bacteria, can perform photosynthesis or obtain energy from inorganic compounds. Protists, such as algae, can also perform photosynthesis and are important primary producers in aquatic ecosystems. Therefore, both Monerans and protists are capable of producing organic matter and are essential for sustaining food webs and ecosystems.

A few cockroaches exhibited pesticide resistance due to natural variability within the population. This means that within the population of cockroaches, there is natural variation in their ability to resist the pesticide. Some cockroaches may have genetic traits that make them more resistant to the pesticide, allowing them to survive even after the pesticide has been applied. This explains why Maria continues to see live cockroaches despite reapplying the pesticide.

Alec is most likely studying a bacterium. Bacteria are microscopic organisms that contain DNA and have a cell wall, but no nucleus. Fungi, protists, and viruses do not fit this description.

The entomologist should give the beetle a new species name not used in the genus Tenebrio because although the beetle closely resembles other darkling beetles of the genus Tenebrio, it has been identified as a new species. Giving it a new species name will help differentiate it from other species within the genus Tenebrio and accurately classify it in the taxonomy system.

The correct answer is Phylum. Phylum is a level of biological taxa that groups together organisms with similar characteristics. Chordata, Molluska, Echinodermata, Arthropoda, and Cnidaria are all examples of phyla.

Dr. Romero is raising two different species of damselfishes. Fish A and C are considered to be a single species, while Fish B is a separate species. This conclusion is based on the most commonly accepted definition of a species, which states that members of the same species can interbreed and produce fertile offspring, while members of different species cannot. Therefore, since Fish A and C can interbreed and produce fertile offspring, they are considered to be the same species, while Fish B is a separate species.

Disruptive selection is the process of natural selection that favors extreme phenotypes of a trait and eliminates intermediate phenotypes. This occurs when individuals with extreme variations of a trait have a higher fitness compared to individuals with average or intermediate variations. As a result, the population becomes divided into two or more distinct groups, with each group having individuals that possess extreme phenotypes. This can lead to the development of new species or subspecies over time.

Genetic biodiversity in modern multicellular organisms is accounted for by mutations in gametes being passed on to offspring. Gametes, such as sperm and eggs, carry the genetic information that is inherited by the next generation. Mutations, which are changes in the DNA sequence, can occur in gametes and result in genetic diversity among offspring. This genetic diversity is essential for the adaptation and evolution of species, as it introduces new variations that can be selected for or against in response to changing environments.

A trait that has evolved through natural selection does not necessarily increase individuals' life spans. Natural selection favors traits that increase an individual's reproductive success, not necessarily their longevity. While increased life span can sometimes be a byproduct of traits that enhance reproductive success, it is not a necessary criterion for evolution through natural selection.
