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.
The carrying capacity of a biological species in an environment is the maximum population size of the species that the environment can sustain indefinitely, given the food, habitat, water, and other necessities available in the environment.
Answer: Testosterone, follicle stimulating hormone
Explanation:
Testosterone is a sex hormone produce by the male sex organs or testes typically in the seminiferous tubules. It incudes male sexual characteristics that is the production and development of sperms in males. The follicle stimulating hormone is involved in causing the maturation of the eggs or female gametes in the female sex organs or ovaries. It also induces the mensuration cycle in females. FSH also have a role in stimulating the spermatogenesis in males as it acts on the Sertoli cells of the testes and stimulates the sperm production.
Answer:
The correct answer is "For different reasons, including: pathogens developed resistance, people traveling much more frequently and practices of terrorism".
Explanation:
Emerging diseases are infectious diseases that are new to a region, or that remerge from a place that were believed to be eradicated. For different reasons emerging diseases are appearing in industrialized countries. One is that pathogens may have developed resistance to the treatments, as they may evolved naturally or it was driven by overuse of antibiotics. Other is that people are traveling much more frequently than in the past, which helps pathogens from distance places to reach industrialized areas. Also, terrorism practices is a cause of introducing pathogens deliberately to a new place.
