Answer:
Percent yield is the percent ratio of actual yield to the theoretical yield. It is calculated to be the experimental yield divided by theoretical yield multiplied by 100%. If the actual and theoretical yield are the same, the percent yield is 100%.
Usually, percent yield is lower than 100% because :
1. The actual yield is often less than the theoretical value.
2. Incomplete reactions, in which some of the reactants do not react to form the product.
3. Practical losses during the experiment, such as during pouring or filtering.
4. Side reactions (unwanted reactions that compete with the desired reaction).
So the dark butterfly camouflages better on the tree. Where as the white one can clearly be seen and identified. A predator will also easily spot it and kill it. The dark butterfly has evolved over time to the color that it is, to best help it survive. This is also shown in the tread on the graph.
Hope this helps!!
Answer:
Explanation:
Dispersion and vicariance are the processes by which speciation is generated in biogeography.
A phylogeny represents the evolutionary relationships between different species.
In this phylogeny, species 5, 1, 6 and 3 originated from vicariance processes, and their position in the phylogenetic tree is due to the order of separation of the mentioned regions. Species 2 and 4 originated from dispersal processes, and are expected to have a closer evolutionary relationship with the species that were in the areas from which they were dispersed, in this case, with Africa and Australia respectively.
