CLICK HERE TO SEE QUESTION 1 Mr аnd Mrs Smith аre bоth keen cyclists аnd adventurers. They are cоnsidering cycling frоm Cape Town to Cairo to raise awareness of a cause special to their hearts – animals. The map on the next page indicates the major routes that connect all the major cities in Africa, collectively known as the Trans African Highways, which they will use to plot their routes. Use the map to answer the questions that follow: 1.1.1 Which two cities indicated on the map are the closest to Cape Town? (2) 1.1.2 Which number represents the Single Trans African Highway that connects Cape Town to Cairo? (2) 1.1.3 Which two cities will they drive through when travelling from Cairo to Algiers along the Trans African Highway? (2) 1.1.4 Would they travel along paved or unpaved roads between Cairo and Algiers? (2) 1.1.5 Which two highways would they have to travel on to drive from Dakar, located on the West Coast of Africa to Djibouti, which is situated on the east coast of Africa? (Provide only the numbers of the highways) (2) 1.1.6 According to the scale, 20 mm on the map represents 1 000 km on the ground. Help complete the following calculation: 20 mm represents (a) __mm on the ground therefore the scale is 1: (b) (4) 1.1.7 If the distance on the map from Cape Town to Gaborone is 128 mm, determine the actual distance in kilometres. (3) 1.1.8 Determine how many full hours it would take to complete the 16750 km distance between Cape Town and Cairo if Mr and Mrs Smith averaged a speed of 11 km/h. (The average speed includes the stops and the rests on route.) You may use the following formula:Distance = speed x time (3) 1.2 When Mr and Mrs Smith reached Mozambique and landed in Maputo, the capital of Mozambique, they noticed a bridge crossing one of the rivers connecting Maputo to the district of Catembe. It was newly built. The population in the district had increased and will aid Maputo in its growth in infrastructure. Refer to the map on the next page and answer the questions that follow. 1.2.1 Determine any two countries that lie on the western border Mozambique. (2) 1.2.2 Give the direction: “Madagascar lies to the _______________ of Mozambique.” (2) 1.2.3 According to an estate agency, Catembe once had a population of 20 000, but since the bridge was built, this figure increased to 400 000. Calculate the percentage increase in population. You may use the following formula: (3) 1.2.4 The bridge is 60 metres high and around 3 kilometres long with six lanes for traffic with three lanes in each direction. 1.2.4.1 What will the total length be, in metres, if all six lanes' lengths are added together? (2) 1.2.4.2 The average length of a car is approximately 16 feet. If 1 meter = 3,28 feet, how long is a car on average in metres? (3) 1.2.4.3 Determine the maximum number of cars that will fit across all six lanes of the length of the bridge. Hint: The lanes are not one long lane/interconnected (4) 1.2.4.4 If the probability of a car being blue in colour in Mozambique is one in five, determine the expected number of blue cars that could be on the bridge across all six of the lanes.

The fоllоwing cоde performs а hierаrchicаl clustering of the 10 protein in a DNAseq. Using the height and merge component yields the same distance conclusion with the cluster dendrogram.mytree = hclust (dna.dist, method="complete") our.tree$height## 79 89 90.5 95 97 105.75 106 108.5 111.33 120.68 Using the above results, answer the following: i) What is the maximum height of the tree? Give the exact value. [max] ii) Which proteins are grouped in cluster 6? [clust6]
