75% of Puerto Ricans who immigrated to the United States After the earthquake at the beginning of 2020, they plan to return to the Island during the summer months 2021. According to the southern newspaper, in the past months there has been an increase in visitors from other countries to the beach areas of the northwest and southwest. On average, a Puerto Rican hostel hosts 45 foreign tourists per week and the standard deviation of 13.5 guests. It is important to establish that 60% of tourists from the Paradores are residents of Puerto Rico. We are interested in knowing how many the average hours employees work and to achieve this we selected a random sample of 32 weeks. Determine: a) What is the probability that the average number of foreign tourists from the sample is between 40 and 48 weekly tourists? b) What is the probability that the average number of foreign tourists be at least 43 a week? .

7-1 Discussion: WorldCom: What Happened? Communication and group dynamics are important elements within the leading facet of the P-O-L-C framework. Read the following article from CNN describing Bernie Ebbers' downfall as CEO of WorldCom: Ex-WorldCom CEO Ebbers guilty. Based on what you read in the article, in your initial post, identify which two barriers to effective communication were most prominent within WorldCom and explain how these barriers led to the downfall of the company. Be specific and identify the communication barriers based on the information in Chapter 11 of your text. .

7.) Some molecular data place the giant panda in the bear family (Ursidae) but place the lesser panda in a very different family, the raccoon family (Procyonidae). Consequently, the morphological similarities of these two species are probably due to: a) the inheritance of acquired characteristics b) sexual selection c) inheritance of shared derived characters d) possession of analogous structures e) possession of shared derived characters 8.) A paraphyletic group includes: a) a basal taxon b) the groups that form the nodes on a phylogenetic tree c) an ancestral species and all of its descendants d) species that show convergent evolution e) an ancestral species and some of its descendants 9.) Since all organisms share a common ancestor, it comes as no surprise that some characteristics are shared while others are not. If we consider hair and the backbone of mammals (which are vertebrates), we can say that the former is a(n) while the latter is a(n) a) monophyletic characteristic, paraphyletic characteristic b) monophyletic characteristic, polyphyletic characteristic c) shared derived character, shared ancestral character d) shared ancestral character, shared derived character e) ingroup, outgroup 10.) Refer to the figure to the right. A group that includes taxa C, D, E, F and G , but not the ancestor is called ... a) a monophyletic group b) the outgroup c) a polyphyletic group d) a paraphyletic group e) the ingroup 11.) An outgroup is an important part of a phylogenetic analysis. What is the function of the outgroup in this type of analysis? a) It reflects the ancestral states of the characters used in the analysis b) It is the species for which we are interested in studying its evolutionary relationship c) It reflects the derived states of the characters used in the analysis d) It reflects the shared derived states (synapomorphies) of the characters used in the analysis 12.) An outgroup should be: a) part of the ingroup b) as closely related to the ingroup as possible without being part of the ingroup c) as distantly related to the ingroup as possible d) the predator of the species in the ingroup .

7. What are the similarities between these surface features? What does this suggest about the possibility of water on Mars? 8. Scientists who disagree with the hypothesis that the Martian channels were caused by flowing water often point out that it is not clear where the water comes from, or where it goes. In the US Rivers image, the waters of the Mississippi River flow from the top of the image in a number of tributaries that combine to form the river that flows off into the Gulf of Mexico at the bottom of the image. Examine the Mars Channels. Which direction (N, NE, E, SE, S, SW, W, NW) is downhill? How do you know? Part 4: Giant Planets Look at the images of the outer Gas Giant Planets. 9. How are the outer (Jovian) planets different from the inner terrestrial planets? Give at least four differences. 10. The bands and stripes on Jupiter, Satum and Neptune are common to all planets with atmospheres. On the Earth, these bands are trade winds (westward surface winds), and jet streams (eastward high-altitude winds). On the Earth, and Venus, the energy that drives the winds comes from the Sun, which heats the ground and the lower atmosphere, starting the process of convection. However, Jupiter, Saturn, Uranus and Neptune have no "ground", and are much too far from the Sun for their winds to be "solar-powered". Where does the energy to drive these winds come from? .

The leaving group that will be displaced (coupling step). c. The oxygen, that if unreacted will be capped (capping step). d. The phosphorus that will be oxidized (oxidation step). 3. What is the phosphorous oxidation state (III or V) in the above monomer? Does this make it more or less reactive than the form found naturally in DNA/RNA? .

The fact that the vast majority of bacteria multiply by binary fission indicates that A. the mother cells constituents must be evenly distributed between the two daughter cells during cell division B. the parent cell gives rise to another cell, identical in size and shape C. the dividing cell does not increase in mass before cell division D. only one of the progeny cells gets the parental genome 8.

7. Over time, mitochondrial DNA accumulates non-lethal mutations at a constant rate. There isa higher degree of variation in mitochondrial DNA in earlier populations than in more recent populations. Scientists have taken samples of mitochondrial DNA from people living on different continents and compared the number of mitochondrial DNA mutations in these samples. They used this data as evidence to determine the order in which Earth's continents were populated. In this study, the manipulated variable was the time of migration from one continent to another geographic location of subjects whose sample of mitochondrial DNA was testec amount of variation in mitochondrial DNA base sequences amount of mitochondrial DNA tested .
