One of the main structures of cells is the plasma membrane, responsible for delimiting the internal and external cellular environment. Regarding the structure and function of the plasma membrane, mark the correct alternative:

The Cerrado has a large part of its area on private lands, requiring the involvement of these properties for the preservation of this biome. Thus, some laws have been created to encourage the conservation of this biome. Which of these laws aims to protect the permanent preservation areas of the Cerrado?

In a genetics experiment, a Biology teacher challenged his 3rd-year high school students to analyze a pea plant that exhibits two characteristics: seed color and seed texture. Seed color can be yellow (AA or Aa) or green (aa), and seed texture can be smooth (TT or Tt) or wrinkled (tt). These characteristics are determined by genes on different chromosomes, so they segregate independently, following Mendel's 2nd Law. The teacher challenges the students to determine the expected phenotypic and genotypic ratios in the F2 (second generation) of a cross between two plants that are heterozygous for both characteristics. Additionally, he asks the students to relate the concept of independent assortment to Mendelian inheritance principles. Based on this information: 1. Calculate the expected phenotypic and genotypic ratios in the F2 of the proposed cross. 2. Explain how the independent segregation of alleles for each characteristic relates to Mendel's 2nd Law and how this principle influences the determination of ratios in the F2.

From the stimuli sent by the sensory neurons, the central nervous system has as its main function to send information to the brain, which will process this information so that it can be properly responded to by the human body. What is the other main function of this system?
