Grasslands are characterized as lands dominated by grasses rather than large shrubs or trees. In the Miocene and Pliocene Epochs, which spanned a period of about 25 million years, mountains rose in western North America and created a continental climate favorable to grasslands. Ancient forests declined and grasslands became widespread. Following the Pleistocene Ice Ages, grasslands expanded in range as hotter and drier climates prevailed worldwide. There are two main divisions of grasslands: (1) tropical grasslands, called savannas, and (2) temperate grasslands.
Answer:
to describe how proteins are produced
Explanation:
The main function of DNA is to carry information contained in its sequences, called genes. Genes are excerpts from the DNA present in chromosomes that initiate protein manufacturing processes with various functions in the body. For proteins to be formed, DNA has to "work". That is, DNA has to start the replication process in order for RNA transcription to be done, so that protein manufacture can finally be done. For this reason, we can conclude that if an author writes "Your DNA at Work", he probably wants to describe how proteins are produced.
Gregor Mendel's research Formed the basis of the field of genetics.
Answer:
Predation and Competition. Two of the main ways that populations interact with one another is by competition and by predation. In competition, individuals seek to obtain the same environmental resource. In predation, one population is the resource of the other.
