In a multicellular organism, all cells generally contain the same genetic information. This is because they arise from a single fertilized egg through the process of mitosis, which is a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus.

Here's a step-by-step explanation:

  1. Origin from a Single Cell: Multicellular organisms begin as a single fertilized egg, or zygote. This zygote contains a complete set of genetic information.

  2. Mitosis: As the organism develops, the zygote undergoes numerous rounds of mitosis. Mitosis is a process where a single cell divides to produce two genetically identical daughter cells. During mitosis, the DNA is replicated so that each daughter cell receives an exact copy of the genetic material.

  3. Genetic Consistency: Because mitosis involves the replication of DNA and equal distribution of the replicated chromosomes to the daughter cells, all cells derived from the original zygote contain the same genetic information.

  4. Cell Differentiation: Although all cells contain the same genetic information, they can differentiate into various cell types with specialized functions. This differentiation is due to the regulation of gene expression, where different genes are turned on or off in different cell types, rather than differences in the genetic code itself.

In summary, all cells of a multicellular organism contain the same genetic information because they arise from the same original cell through mitosis, which ensures the faithful replication and distribution of genetic material.

Your school will be hosting a regional educational conference in a few weeks and the dean has asked several student groups to help get the campus ready. He asks the service fraternity to plant flowers outside of the student union. The dean asks the student government members to paint the benches around campus and he asks the marching band to place mulch around the trees on campus. Unfortunately, it rained the entire week leading up to the educational conference and the student government members lacked because they were unable to paint all of the benches on campus. Mary is a baker who makes the most beautiful and delicious cakes in town. Unfortunately, her cakes are also very expensive because for every cake she produces, she throws away three cakes that aren't just right. What is the best way to describe Mary's work?

The tropopause is a defined boundary that separates the troposphere (below) from the stratosphere (above). At the tropopause, the temperature trend changes from decreasing significantly as altitude increases to nearly constant (isothermal) or begins to increase with altitude (called a temperature inversion) in the lower stratosphere. Based on the temperature pattern you plotted, the tropopause in the Salt Lake City example sounding was located at a pressure level above mb . a. 700 b. 500 c. 300 d. 200 The tropopause over Salt Lake City occurred at an altitude nearest km above sea level, according to the altitude scale on the Stüve diagram. This can be confirmed from the observed altitude reported in Table 2B-1. a. 6 b. 9 c. 12 d. 16 This Salt Lake City tropopause was altitude compared to the altitude of the tropopause in the Standard Atmosphere. The Standard Atmosphere tropopause occurs at 11 km . a. at a lower b. about the same c. at a higher Since the weight of the overlying air determines air pressure, this means about half of the weight of air over Salt Lake City's atmosphere was above 500 mb and half below. In Table 2B-2, the pressure of 500 mb occurred at an altitude of m. a. 2943 b. 5390
