<span>Phylogenetic tree is a tree that shows the evolutionary relationships between several species or other entities that are believed to have a common ancestry. A phylogenetic tree is a form of a cladogram.
In addition, a phylogenetic tree serves to determine the minimum number of divisions necessary to obtain a specific cell or tissue. From here, you can study, for example, the mutations generated throughout the process.</span>
Answer:
eukaryotic cells have a nucleus whereas prokaryotic cells do not
The factors that determines the rate of diffusion in the biological system include: temperature, size of the particles, diffusion distance and concentration gradients. Of all these factors, the most important one is the TEMPERATURE.
The relationship between temperature and the rate of diffusion is a direct one, that is, the higher the temperature the higher the rate of diffusion and vice versa. At high temperature the molecules in the particles move faster because they have higher amount of energy.
High pressure. Clouds form due to air rising so if the pressure is high, it pushes down on the air which prevents cloud formation.
Answer:
The trilobite is the oldest.
Explanation:
In general terms (disregarding specific examples), the lower the level in the stratosphere, the older it is. In this case, the lowest level is taken by the trilobite.
Note however, that this is not always the case, especially near edges of the plates. Sometimes plates shift, which can cause certain older fossils to be moved upwards, while newer ones are shifted downward, as one plate "eats the other". Territory creations, including valleys and mountains when plates crash into each other, can also shift where a fossil is located.
