Explanation:
Classification systems function in order to organize a group of organisms into smaller groups according to some kind of logic. For example, the most used classifications system in biology is the phyllogenetic, which classifies living beings according to their evolutive affinity.
In the other hand, a dichotomous key is a "guide" used by biologists when they need to indentify an individual. It is organized in several steps regarding some key characteristics in order to guide you to which species/genus/family your individual belongs to. A dichotomous key never provides any kind of trustworthy phyllogenetic information, and should be understood only as a tool.
Answer:
Explanation:
Human activities have a tremendous impact on the carbon cycle. Burning fossil fuels, changing land use, and using limestone to make concrete all transfer significant quantities of carbon into the atmosphere. As a result, the amount of carbon dioxide in the atmosphere is rapidly rising.
Meiosis occurs in a series of different phases and creates genetically unique reproductive cells. The process which helps make meiotic cells genetically different and occurs during prophase I, but not during prophase II, is crossing over (C). Crossing over is the exchange of genetic material between two homogenous chromosomes. It is one of the final phases of prophase I. This process is called synapsis. It occurs when the matching regions on the matching chromosomes break and then reconnect to the other chromosome
Part one is a semi-permeable membrane that separates the two solutions and allows bi-directional transport
Answer:
Sensory transduction
Explanation:
Sensory transduction is a process by which the sensory neuron transforms the obtained sensory information into an electric signal. Sensory neurons are the afferent neurons and are activated when they receive stimulus from a sensory receptor. This is followed by the firing of action potential to convey the sensory information into the CNS through the cranial or spinal nerve.
Change in temperature serves as a stimulus for thermosensory neurons present in the skin. The activated thermosensory neuron then produces an electric signal by the process of sensory transduction during which a nerve impulse is generated and action potential to convey the information.
