The option that is not a disadvantage of dam and reservoir systems is: **d. It reduces water loss through evaporation.** Reducing water loss through evaporation is generally considered an advantage of having a dam and reservoir system, as these structures can help to store water that might otherwise be lost to evaporation in more open water bodies. The other options listed are indeed disadvantages associated with dam and reservoir systems.

Food stability primarily relates to: **b. Access to food at all times with no risk of losing such access.** Food stability encompasses the reliability and consistent availability of food, ensuring that people have ongoing access without the uncertainty of potential shortages or disruptions.

The most accurate statement regarding advances in agricultural biotechnology is: **b. help meet the increasing demand for food in the world and help to offset land demands.** Agricultural biotechnology has the potential to improve crop yields, enhance resilience to pests and diseases, and reduce the need for chemical inputs, thus contributing to food security and reducing the pressure on land use.

The process through which uranium ore from a conventional mine is usually refined into uranium concentrate is: **c. Milling**

Based on your description, I cannot see the figure or the details within it. However, I can provide general insights regarding the immigrant populations of the mentioned countries. 1. **North America vs. South America**: North America typically has a higher percentage of immigrants, especially in the United States, compared to South American countries. 2. **Australia's Immigrant Population**: Australia is known for having a significant

Proses restorative justice dapat bervariasi dalam lamanya tergantung pada berbagai faktor, seperti kompleksitas kasus, jumlah pihak yang terlibat, dan kesediaan semua pihak untuk berpartisipasi. Secara umum, proses ini dapat berlangsung dari beberapa minggu hingga beberapa bulan. Tahapan dalam restorative justice biasanya meliputi: 1. **Persiapan**: Mengidentifikasi semua pihak yang terlibat dan mempersiapkan mereka untuk proses restoratif. Ini

d. A rapidly expanding population An age-structure diagram with a pyramidal shape, featuring a large base of younger individuals and many individuals in the reproductive age group, indicates a rapidly expanding population. This shape suggests that a high birth rate is present, leading to more young people compared to older age groups.

The false statement is: **b. Traditional health hazards are prevalent in industrialised countries and are caused by technological developments.** Traditionally, health hazards such as infectious diseases and conditions related to poverty were more prevalent in less industrialized countries. In industrialized countries, while some health hazards have emerged due to technological developments (like lifestyle diseases), traditional health hazards

The correct answer is: b. neurotoxicants Lead and mercury are known to have toxic effects on the nervous system, classifying them as neurotoxicants.

c. a population overshoots carrying capacity and uses up their resource supply

Cold deserts are best described by: **e. experience freezing temperatures during the winter and any precipitation is in the form of snowfall.** This characteristic highlights the cold temperatures typical of cold deserts and the nature of precipitation they receive.

An ecological niche includes all of the following except: **c. the place where the species lives** While the niche encompasses the role and interactions of a species within its environment (including resource use and requirements), the specific physical location where a species lives is typically referred to as its habitat rather than its niche.

The false statement is: **b. The Red List of Threatened Species is comprehensive and complete.** The Red List, while extensive and valuable, is not comprehensive or complete, as it only includes a portion of the world's species and many species have not yet been assessed or described.

The action that leads to a decrease in biodiversity is: **a. Introduction of exotic species** Introducing non-native species can disrupt local ecosystems, outcompete native species for resources, and lead to a decline in biodiversity.

c. studies the past distribution of species

The diversity that enables species to adapt to and survive environmental changes is known as **c. Genetic diversity**. Genetic diversity refers to the variety of genes within a species, which allows for variations that can help populations adapt to changing conditions over time.

The process that leads to an increase in biodiversity is: **c. Removal of exotic species** Removing invasive or exotic species can help native species thrive, thereby increasing overall biodiversity in an ecosystem. Other options listed are more associated with negative impacts on biodiversity.

I'm unable to view images directly. However, I can provide definitions for the terms you provided to help you identify what might be represented in the image: a. **Primary succession**: This occurs in lifeless areas where soil has not yet formed, such as after a volcanic eruption or glacial retreat. It involves the colonization of bare rock by organisms starting with lichens and mosses. b. **Secondary succession**: This happens in areas where a
