Evolutionary Biology Question 3 parts: explain why Fst increases with distance.... in thankyou
. It has been observed that Fst increases with the distance between populations in many species. Explain why. (2 marks)
Increased distance leads to more isolation and less access to reproductive opportunities between populations decreasing genetic exchange.

b.   Let us imagine that we observe that Fst increases more rapidly with distance for mitochondrial DNA than for

Drag the labels onto the graph to indicate which presynaptic neuron produced each change in the axon
Question :
 Drag the labels onto the graph to indicate which presynaptic neuron produced each change in the axon hillock’s membrane potential. Assume that the same number of ligand-gated ion channels opens at each synapse. (To review the effect of distance between the synapse and the axon hillock, see Hint 2.) Labels can be used once, more than once, or not at all.

oxygen consumption in cellular respiration.
When seeds germinate, they use cellular respiration to release stored chemical energy that will enable the growth of the seedling. As you have learned in previous science courses, oxygen is an important reactant in this process. In this activity you will investigate the level of cellular respiration of germinating seeds by measuring t
