The Correct Answer and Explanation is: 2. Choose the substance with the highest viscosity: The viscosity of water generally decreases as temperature increases, because higher temperatures cause molecules to move faster, which decreases the internal friction. Therefore, water at 10°C will have the highest viscosity compared to the other temperatures (20°C, 30°C, 40°C, 50°C). This […]

Which neurotransmitters produce IPSPs? Multiple select question. Glycine Aspartate GABA Glutamate The correct answer and explanation is: The correct answers are Glycine and GABA. Explanation:Neurotransmitters are chemicals that transmit signals across synapses in the nervous system. Depending on their effects on the postsynaptic neuron, neurotransmitters can cause excitatory or inhibitory postsynaptic potentials (EPSPs or IPSPs).

Example of an abiotic factor? The correct answer and explanation is: An example of an abiotic factor is temperature. Abiotic factors are the non-living components of an ecosystem that influence living organisms. These factors include elements like light, temperature, water, soil, and air, and they play a crucial role in determining the types of organisms
