THE “DOOMSDAY VAULT” IS IN DANGER Svalbard Global Seed Vault (SGSV) is a seed bank located in Arctic Norway. The seeds are kept at -18 °C with minimum access to oxygen in order to delay aging as much as possible. The vault is also surrounded by frozen soil called permafrost. However, global warming is causing the permafrost to melt and the vault is in danger of flooding. SGSV keeps seeds from almost 4 000 species of plants, focusing on food crops such as wheat, rice and maize. SGSV keeps seeds from more than 865 000 varieties of plants, including 200 000 varieties of wheat and rice. Some of these varieties are rare or extinct in the wild. [Adapted from "The Doomsday Vault Is In Serious Danger" by Alfredo Carpineti, 07 Feb. 2019.] 2.4.1 What are suitable conditions for keeping seeds in a seed bank, according to the article? (1) 2.4.2 What environmental event is threatening the safety of the seeds at the Global Seed Vault? (1) 2.4.3 Give THREE different ways in which seeds provide a source of food for humans. (3) 2.4.4 Why are seed banks important for the future? (2) The purpose of SGSV is to store seeds for use 50 or more years from now. Seeds from three varieties of maize were tested to see the effects of long periods of storage. The results of these tests are shown in the graph. 100 KEY: 90 Variety A Germination (%) --- Variety B ….

The Water Hyacinth is an invasive alien plant that has taken over South African rivers, dams and lakes. If left uncontrolled, Water Hyacinth grows and forms a thick layer that covers the surface of the water. The weevil, Neochetina eichhorniae, has been very effective in controlling the Water Hyacinth. The weevil feeds on the soft parts of the plant, preventing the plant from reproducing and causing it to break up. Researchers wanted to determine the optimum number of weevils to release per plant.  They grew Water Hyacinth in six large water tanks.  They placed a different number of weevils in each tank.  They then recorded the number of days it took the weevils to control the Water Hyacinth. The results are recorded in the table below. Number of weevils per plants Days taken to control water placed in tank hyacinth 4 50 8 40 12 30 16 20 20 20 Control (no weevils) No change in Water Hyacinth 3.2.1 Name the method used when a natural pest is released to control an alien invasive species.

(1) 3.2.6 For the above investigation, give the: (a) Dependent variable (1) (b) Independent variable (1) 3.2.7 Give TWO factors that will need to be controlled to ensure that the investigation is valid. (2) 3.2.8 Explain the negative impact that Water Hyacinth will have for: (a) A farmer (2) (b) A sportsman who enjoys swimming and canoeing (2) 3.3 Read the passage below and answer the questions that follow. SA WONDER PLANT REMOVES MORE CO2 THAN AMAZON Spekboom is our own indigenous wonder plant found in the Eastern Cape and an important ‘weapon’ in the fight against climate change. The Spekboom is ten times more effective than the Amazon rainforest at sucking carbon dioxide out of the atmosphere. It is especially good at photosynthesis, which produces a by-product we desperately need. Kuzuko Lodge, a private game reserve next to Addo Elephant National Park, is able to sell carbon credits due to this miracle bush which occurs naturally there. Governments in Europe want to reduce industrial pollution and tax companies heavily for excess carbon emissions. Therefore, businesses that produce high levels of greenhouse gas emissions, like transport companies, can buy carbon credits to offset their carbon footprint. [Adapted from https://www.getaway.co.za/travel/nature-and-conservation/sa-wonder-plant- removes-more-carbon-dioxide-than-amazon/] 3.3.1 What does the term carbon footprint mean?

However, nowadays they make a very small contribution to South Africa’s gross domestic profit. Unfortunately, they do have a big impact on the environment. Explain the impact of agriculture and mining on the quality and availability of water in South Africa.
