Answer:
The phylogenetic graph uses several types of variables to be formed, while other models use only one type of variable.
Explanation:
To create a phylogenetic chart, matrices with data on the studied species are used. These data are composed of morphological, chemical and / or genetic information that allow a detailed investigation about the ancestry of each species, in addition to allowing the correct grouping based on this ancestry and evolution.
A phylogenetic graph is different from other molecular models due to the number of data considered by it, since other models, such as the molecular clock, for example, only consider genetic based information.
Answer:
The correct answer will be option-pollen.
Explanation:
The pollen are the male gametophyte which is produced in the seed plants.
The pollen produce male gametes after entering the female gametophyte. The male gametes fuse with the egg cell and form the embryo inside ovary which matures and forms seeds. The vascular seed plants lack these pollen but instead produces male gametes in gametangia which are replaced by the pollen in the seed plants.
Thus, option-pollen is the correct answer.
Answer:
it is every organisms goal to "survive and repopulate" therefore, with natural selection the weaker organisms die because they did not possess the traits necessary to survive, and the strong survive and repopulate
