Answer:
Xiao can use these structures to create a similarity matrix that enables to differentiate between synapomorphies and homoplasies
.
Explanation:
A synapomorphy is a trait that has been inherited from the same ancestor, this trait enables to establish a relation of homology between two or more species; while a homoplasy is an analog structure that doesn't have homology.
<span>By using superposition and cross cutting relationships, geologists can determine relative ages of rocks. This means they can determine which rocks are older and which are younger, but not the exact ages of the rocks. </span>
Measuring photosynthesis via the production of oxygen. Oxygen can be measured by counting bubbles evolved from pondweed, or by using the Audus apparatus to measure the amount of gas evolved over a period of time.The emerging bubbles are either simply counted or they are recorded using light barriers, which is very difficult because of their small size and often varying ascent rate. The gas bubbles generated during photosynthesis by aquatic plants produce distinctive sound pulses when leaving the plants.
