To explain: With regard to anterolateral pathway, the type of sensory receptors involved and the type of sensory information that is being provided to the brain.
Concept introduction: The nerve signals are relayed from the brain to other organs through the spinal cord. Based on the direction of nerve signals, synapse conduction pathways are of two types: sensory pathways or motor pathways. Sensory pathways are also known as ascending pathways and relay sensory input to the brain. There are three somatosensory pathways: posterior funiculus-medial lemniscal pathway, anterolateral pathway, and spinocerebellar pathway.

To explain: With regard to anterolateral pathway, location of each of the sensory neurons within the chain of three neurons that compose this pathway.

- One of the ways for a cell to generate ATP is through the oxidative phosphorylation. In oxidative phosphorylation 3 ATP are produced from every one NADH molecule. In respiration, every glucose molecule produces 10 NADH molecules. If a cell is growing on 5 glucose molecules, how much ATP can be produced using oxidative phosphorylation/aerobic respiration?arrow_forwardIf a cell is growing on 5 glucose molecules, how much ATP can be produced using oxidative phosphorylation/aerobic respiration?arrow_forwardHow do i know which way the arrows go?arrow_forward

Please note that the focus of this assignment are the (biological) scientific issues associated with rewilding. As will be discussed in class, there are a number of non-scientific issues involved or implicated in rewilding, all ultimately affecting the public acceptability of rewilding. Although these issues are important – indeed, critical – in this assignment you should focus on the biological science issues and questions. Details: You must enumerate at least two pros and at least two cons. Your answer should be no more than 500 well-chosen words, excluding references. Think carefully about how best to organize and structure your answer. Aim for high information density: say a lot, but say it succinctly.
