Always take note of the unit in which the answer must be given – this will usually be m² or km².
ACTIVITY 1: [LO 1.3]
The length of a rectangular object is 5,6 cm and the width is 3,4 cm on a 1 : 50 000 topographic map. Calculate the area of the object in km².
The length of a building is 1,1 cm and the width is 0,6 cm on a 1 : 50 000 topographic map. Calculate the area of the building in m².Calculating time between 2 points.
Remember the following:
The distance completed will have to be calculated from the map and be given in real km. Speed or time will always be provided.
How long will it take to travel by car at 60 km/h from point A to point B?
Steps:
ACTIVITY 2: [LO 1.3]
At what time will a person arrive at a destination if he or she leaves the house at 7:00 and travels a distance shown as 8 cm on a 1 : 50 000 map? Reading and analysing maps
Topographic maps are among the most useful and precise maps that are available because of the amount of detail that they contain and the precision with which the minutest details are indicated.
Topographic maps and orthophoto maps provide the geographer’s tools (SOURCE) and the reader needs to understand the language of the map. This makes it possible to give scientific explanations of features.
The activities that follow will help the learner to master map-reading techniques and skills and to extend his or her knowledge of Bloemfontein.
ACTIVITY 3: [LO 1.7]
Consult your atlas to answer the following questions:
Find out where Bloemfontein is situated by using the index at the back of the atlas.
In which province of South Africa is Bloemfontein?
Indicate the direction to Durban from Bloemfontein.
Measure the distance between Edenburg (south of Bloemfontein) and Bloemfontein in km, using the linear scale given for the map in your atlas.
At what time will a bus arrive in Bloemfontein if it leaves Edenburg at 10:00 and travels at an average speed of 120 km/h, without stopping along the way?
Read the accompanying text and answer the questions dealing with Bloemfontein’s past.
Provide reasons for the city’s:
origin;
development as a city.
The development of Bloemfontein
More that a hundred years ago, trekkers from the Cape settled in the environment of Bloemfontein, which quickly developed into a centre for trading. In 1846, the location of the present city was selected by Major Warden as the most convenient site for building a fort and a residential area. From this beginning, and in spite of setbacks resulting from unrest and wars, which inhibited its development, the small town developed into an attractive city.
Bloemfontein forms the geographical hub of South Africa’s railway, road and airline services. The development of the Free State gold mines, less than 160 km from the city, has brought additional prosperity to the city, which is fast becoming an important industrial centre.
The city is situated in a picturesque environment in the heart of the Free State plateau, surrounded by hillocks and hills rising high above the plains. To the north is Naval Hill, from where there is a particularly beautiful view of the city.
Bacteria doesn't produce energy they are dependent upon their substrate in case of lack of nutrients they are able to make spores which helps them to sustain in harsh environments
_Adnan
But not all bacteria make spores, l mean Eukaryotic cells have Mitochondria which acts as powerhouse for them, since bacteria don't have it, what is the substitution for it?
Assimilatory nitrate reduction is a process that occurs in some microorganisms, such as bacteria and archaea, in which nitrate (NO3-) is reduced to nitrite (NO2-), and then further reduced to ammonia (NH3).
Elkana
This process is called assimilatory nitrate reduction because the nitrogen that is produced is incorporated in the cells of microorganisms where it can be used in the synthesis of amino acids and other nitrogen products
There are nothing like emergency disease but there are some common medical emergency which can occur simultaneously like Bleeding,heart attack,Breathing difficulties,severe pain heart stock.Hope you will get my point .Have a nice day ❣️

define infection ,prevention and control
Innocent
I think infection prevention and control is the avoidance of all things we do that gives out break of infections and promotion of health practices that promote life
