There are 4 evolutionary mechanisms : Natural selection, gene flow,mutations and genetic drift.

In our case, we are talking about the natural selection.

Natural selection is an evolutionary mechanism that favors individuals that are the most fit for their environment. Certain individuals in a population can have a trait that gives them a survival advantage over the other individuals in the population. Natural selection favors these individuals and they leave more offspring and are more successful. In the case of lung fishes, their lungs were a trait that gave them a huge advantage because it enabled them to live outside the water and use new resources available on land.

How could the notion of maximum parsimony lead to an error in establishing an evolutionary relationship
Grace [21]

Answer:

The notion of maximum parsimony does not consider the entire evolutionary history, being able to suppress important evolutionary points that would cause errors in the evolutionary relationship of a species.

Explanation:

Maximum parsimony is a criterion for optimizing phylogenetic trees. This is because through this criterion an analysis is made of all possible phylogenetic trees of a species, observing which one is smaller and offers simpler and summary information. On the one hand, the study of the smallest phylogenetic tree can be faster and more understandable, since its information is basic and direct. However, maximum parsimony can lead to errors in the establishment of an evolutionary relationship of a species, because it suppresses the entire history of evolution of that species, being able to suppress really important points in one of the clades, which would result in an incorrect evolutionary conclusion.

Consider the regulation of galactose metabolism through GAL4. Which of the following would result from a mutation that allowed G
evablogger [386]

Answer: Option C.

GAL80 would be able to bind to GAL4, and transcription of the genes involved in galactose metabolism would be repressed.

Explanation:

Gal 3, Gal 80 and Gal 4 are form of proteins which participate in metabolism. They constitute a galactose-responsive switch for the GAL genes When galactose is absent, Gal 80 bind to Gal 4, masking the Gal4AD prevent gene transcription and prevents Gal4-mediated promoter activation

What effect did the development of the first forests have on carbon dioxide in the atmosphere?
Sladkaya [172]
It decreased the amount of carbon dioxide in the air and increased the amount of oxygen because plants go through photosynthesis and convert carbon dioxide to oxygen in the process.
