Which can modern taxonomy do? design tables based on physical characteristics compare the length of DNA among members of a species compare the length of RNA among members of a species distinguish how closely related organisms are

Some species form social groups only with members of the same gender. For example, elephants form groups with only females and their offspring. Once the male offspring reach a certain age, they leave the group and become solitary. Which is a benefit of this type of social group structure? Females do not have to compete for a mate. Male offspring can belong to more than one social group. Adult males can mate with females in several different social groups. Females are the only ones responsible for taking care of the offspring.

Which protist exhibits both animal-like and plant-like characteristics? a protist that has pseudopods and swims by using cilia a protist that makes its own food and has glass-like cell walls a protist that is a heterotroph and has chlorophyll a protist that can move or be stationary

Which correctly distinguishes between how a pine tree and an apple tree reproduce? The pine tree bears flowers; the apple tree does not have any flowers. The pine tree has unprotected seeds; the apple tree has seeds in fruit. The pine tree is vascular; the apple tree is a seedless, nonvascular plant. The pine tree is nonvascular; the apple tree is vascular.

Consider these phylogenetic trees. The first tree is based on physical characteristics. The second tree is based on structure, genetics, and evolutionary history.Which can be concluded from a comparison of the two phylogenetic trees? Phylogenetic trees are not subject to change. Classification can change with new discoveries and evidence. Classification does not change with more evidence. Phylogenetic trees are inaccurate.

Which best describes the difference between protists that have cilia and those that have flagella? Those that have cilia are animal-like protists, and those that have flagella are plant-like protists. Those that have flagella are animal-like protists, and those that have cilia are plant-like protists. Those with cilia move using hair-like extensions, and those with flagella move using a single whip-like extension. Those that have cilia are heterotrophs, and those that have flagella are autotrophs.

Which of the labeled structures in the image allows bacteria to exchange genetic material and thus evolve to be better pathogens? A B C D

Once the body has begun shivering, what happens to make it stop shivering? When body temperature returns to normal, the respiratory system sends a message to the skeletal system to stop shivering. When body temperature returns to normal, the nervous system sends a message to the muscular system to stop shivering. When body temperature is below normal, the nervous system sends a message to the skeletal system to stop shivering. When body temperature is below normal, the respiratory system sends a message to the muscular system to stop shivering.

The lungs, nose, and trachea are organs of the respiratory system. Which best describes these organs? They deliver nutrients to the other tissues. They deliver oxygen to the blood. They are both used for support. They help break down food.

An organism has the following characteristics: cell wall, autotrophic, unicellular, and eukaryotic. What kingdom does it most likely belong in? Animalia Protista Plantae Eubacteria

Which statement best describes the flower based on its physical characteristics? The tulip plant is classified as a dicot. The tulip plant has netted veins. The tulip plant has ring-like vascular bundles. The tulip plant is categorized as a monocot.

Which type of bacterial reproduction is depicted in the diagram? binary fission transduction conjugation transformation

Brown bears pant, which means they breathe with short, quick breaths. This helps circulate cool air over moist surfaces in the mouth. What are brown bears doing as a result of panting? maintaining internal water levels by releasing moisture maintaining internal water levels by taking in moisture maintaining body temperature by warming up maintaining body temperature by cooling down

Termites are insects that live in colonies. In a colony, the king and a queen are responsible for reproduction. Workers spend most of their time caring for the other termites and building the nest. Soldiers protect the nest from attacks. The organization of the termite colony is an example of which benefit of social behavior? foraging protection reproduction division of labor

A biologist is studying two organisms, X and Y. She knows that at least one of them is an animal. Organism X only reproduces sexually. Organism Y reproduces both sexually and asexually. Which conclusion is best supported by the information? Organism X is an animal, and organism Y is not. Organism Y has the benefit of not having to find a mate. Organism X has offspring that are not genetically diverse. Organism Y is a heterotroph, and organism X is not.

When protists and fungi are compared, which feature is unique to protists? spores hyphae flagella pseudopods

The classification levels of a human are listed below from largest to smallest.EukaryaAnimaliaChordataMammaliaPrimatesHominidaeHomosapiensWhich level of biological classification do Mammalia and Hominidae represent, respectively? class and family order and class family and species species and kingdom

A biologist is in the process of classifying a newly discovered fungus. The fungus is a decomposer and has saclike structures. The organism most likely belongs in the same group as which of the following? fungi that are rusts fungi that are associated with bread mold fungi that makes blue cheese fungi that are autotrophic decomposers

A group of sheep run in random directions to confuse a single predator. This is an example of which social behavior? migrating herding schooling cooperative hunting

Which characteristic describes the whale but not its food source, the phytoplankton? The whale is heterotrophic. The whale has cell walls. The whale is unicellular. The whale is a prokaryote.

Neurons and neuroglia work together to form nervous tissue, which is part of the nervous system. Which describes neurons and neuroglia? They are specialized organs that form an organ system. They are organs that form tissue. They are specialized tissues that form an organ system. They are cells that form tissue.

Lewis is exercising and his muscles need oxygen. Which best describes how systems interact to bring his body into homeostasis? The circulatory system brings oxygen to the respiratory system, which delivers oxygen to the muscular system. The respiratory system brings oxygen to the circulatory system, which delivers oxygen to the muscular system. The respiratory system brings oxygen to the circulatory system, which delivers oxygen to the skeletal system. The circulatory system brings oxygen to the respiratory system, which delivers oxygen to the skeletal system.

Which type of social behavior is shown in the image? herding dividing labor schooling flocking

A botanist has discovered a new plant species and is trying to classify the plant. Its seed has one cotyledon, it has six flower parts, its leaves have parallel veins, its stem is herbaceous, and the vascular bundles in its stem are scattered throughout the stem.
