Answer the following question given this paragraph: 44.3 | Terrestrial Biomes By the end of this section, you will be able to: Identify the two major abiotic factors that determine terrestrial biomes Recognize distinguishing characteristics of each of the eight major terrestrial biomes The Earth's biomes are categorized into two major groups: terrestrial and aquatic. Terrestrial biomes are based on land, while aquatic biomes include both ocean and freshwater biomes. The eight major terrestrial biomes on Earth are each distinguished by characteristic temperatures and amount of precipitation. Comparing the annual totals of precipitation and fluctuations in precipitation from one biome to another provides clues as to the importance of abiotic factors in the distribution of biomes. Temperature variation on a daily and seasonal basis is also important for predicting the geographic distribution of the biome and the vegetation type in the biome. The distribution of these biomes shows that the same biome can occur in geographically distinct areas with similar climates (Figure 44.12). Q: The earth's biomes are categorized into two major groups named what? Choices: - icelandic and aquatic - aquatic and galactic - terrestrial and galactic - terrestrial and aquatic A:
terrestrial and aquatic
Answer the following question given this paragraph: Sensory-Somatic Nervous System The sensory-somatic nervous system is made up of cranial and spinal nerves and contains both sensory and motor neurons. Sensory neurons transmit sensory information from the skin, skeletal muscle, and sensory organs to the CNS. Motor neurons transmit messages about desired movement from the CNS to the muscles to make them contract. Without its sensorysomatic nervous system, an animal would be unable to process any information about its environment (what it sees, feels, hears, and so on) and could not control motor movements. Unlike the autonomic nervous system, which has two synapses between the CNS and the target organ, sensory and motor neurons have only one synapseone ending of the neuron is at the organ and the other directly contacts a CNS neuron. Acetylcholine is the main neurotransmitter released at these synapses. Humans have 12 cranial nerves, nerves that emerge from or enter the skull (cranium), as opposed to the spinal nerves, which emerge from the vertebral column. Each cranial nerve is accorded a name, which are detailed in Figure 35.28. Some cranial nerves transmit only sensory information. For example, the olfactory nerve transmits information about smells from the nose to the brainstem. Other cranial nerves transmit almost solely motor information. For example, the oculomotor nerve controls the opening and closing of the eyelid and some eye movements. Other cranial nerves contain a mix of sensory and motor fibers. For example, the glossopharyngeal nerve has a role in both taste (sensory) and swallowing (motor). Q: Motor neurons and sensory neurons are part of what nervous system? Choices: - peripheral - central - autonomic - sensory-somatic A:
sensory-somatic
Q: Answer the following question given this paragraph: Habitats Although fungi are primarily associated with humid and cool environments that provide a supply of organic matter, they colonize a surprising diversity of habitats, from seawater to human skin and mucous membranes. Chytrids are found primarily in aquatic environments. Other fungi, such as Coccidioides immitis, which causes pneumonia when its spores are inhaled, thrive in the dry and sandy soil of the southwestern United States. Fungi that parasitize coral reefs live in the ocean. However, most members of the Kingdom Fungi grow on the forest floor, where the dark and damp environment is rich. Q: Most members of what kingdom of spore-making organisms grow on the forest floor, where the dark and damp environment is rich? Choices: - algae - moss - bacteria - fungi A:
A: fungi
Question: Answer the following question given this paragraph: Plants have evolved three pathways for carbon fixation. Q: How many pathways do plants have for carbon fixation? Choices: - two - five - eleven - three A:
Answer: three
*Question*
Answer the following question given this paragraph: All chemical reactions involve energy. Some chemical reactions consume energy, whereas other chemical reactions release energy. Chemical reactions can be either spontaneous, which do not require an input of energy, or non-spontaneous, which does require an input of some type of energy. Energy may be in the form of heat, light or electricity. Each of the energy changes that occur during a reaction are graphed in Figure below . In the reaction on the left, energy is released. In the reaction on the right, energy is consumed. Q: What types of energy is released during a chemical reaction? Choices: - human, magnetic, electrical - temperature , electricity , light - magnetism, electricity, light - heat, electricity, light A:
**Answer**
heat, electricity, light
Q: Answer the following question given this paragraph: Intraspecific competition occurs between members of the same species. For example, two male birds of the same species might compete for mates in the same area. This type of competition is a basic factor in natural selection. It leads to the evolution of better adaptations within a species. Q: Competition between members of the same species is known as? Choices: - interspecies competition - egregious competition - nuchal competition - intraspecific competition A:
A: intraspecific competition
