Q: Q: Sounds, chemicals, and visual cues are examples of what between animals? Read this paragraph and choose the correct option from the provided answers: For individuals to cooperate, they need to communicate . Animals can communicate with sounds, chemicals, or visual cues. For example, to communicate with sounds, birds sing and frogs croak. Both may be communicating that they are good mates. Ants communicate with chemicals called pheromones . For example, they use the chemicals to mark trails to food sources so other ants can find them. Male dogs use pheromones in urine to mark their territory. They are "telling" other dogs to stay out of their yard. You can see several examples of visual communication in Figure below . Choices: - migration - circulation - procreation - communication A:
A: communication

Q: Q: Categorized based on how they produce their mrna using the baltimore classification method, what consist of a nucleic acid core surrounded by a protein capsid with or without an outer lipid envelope? Read this paragraph and choose the correct option from the provided answers: CHAPTER SUMMARY 21.1 Viral Evolution, Morphology, and Classification Viruses are tiny, acellular entities that can usually only be seen with an electron microscope. Their genomes contain either DNA or RNAnever bothand they replicate using the replication proteins of a host cell. Viruses are diverse, infecting archaea, bacteria, fungi, plants, and animals. Viruses consist of a nucleic acid core surrounded by a protein capsid with or without an outer lipid envelope. The capsid shape, presence of an envelope, and core composition dictate some elements of the classification of viruses. The most commonly used classification method, the Baltimore classification, categorizes viruses based on how they produce their mRNA. Choices: - bacteria - amphibians - parasites - viruses A:
A: viruses

Q: Q: The relationships between groups of different species makes up a ___________. Read this paragraph and choose the correct option from the provided answers: A community is made up of the relationships between groups of different species. For example, the desert communities consist of rabbits, coyotes, snakes, birds, mice and such plants as sahuaro cactus, ocotillo, and creosote bush. Community structure can be disturbed by such dynamics as fire, human activity, and over-population. Choices: - species - family - food chain - community A:
A: community

Q: Q: Deceleration is the opposite of what? Read this paragraph and choose the correct option from the provided answers: Discussion The minus sign indicates that acceleration is to the left. This sign is reasonable because the train initially has a positive velocity in this problem, and a negative acceleration would oppose the motion. Again, acceleration is in the same direction as the change in velocity, which is negative here. This acceleration can be called a deceleration because it has a direction opposite to the velocity. Choices: - stopping - stimulation - vibration - acceleration A:
A: acceleration
