EmSAT Biology Practice Test With Answers

EmSAT Achieve Biology test is one of the electronic Emirates standard tests where it is imposed on students of the twelfth grade to measure and determine their skills and information in the subject of biology and their readiness to attend college. 

EmSAT Achieve Biology Public Test Specification

The EmSAT Biology Achieve is a standardized computer-based test that measures the proficiency level of grade 12 students in Biology and determines their readiness for college. The Benefit of the EmSAT exam is that it can evaluate a person’s knowledge and skills in various subjects. 

EmSAT Biology Achieve has four major sections: (1) From molecules to living organisms - Structure and function; (2) Heredity and genetic technology; (3) Evolution and Diversity of Life; (4) Ecology - Interdependence, energy, and dynamics. Test sections, questions, and options are randomized and timed by the computer. Test takers can see how much time they have throughout the test.

EmSAT Achieve Biology: Content Areas

Appendix 1

Below are the major sections and related content specifications that grade 12 students should be able to demonstrate to meet the expectations of this test. 

Section 1: From molecules to living organisms: Structure, function, and behavior 

This section includes the chemistry of life as well as living organisms’ organization and development. The chemistry of life focuses on the importance of biological macromolecules in the body and the properties of water that allow life to exist on earth, as well as the role of enzymes in chemical reactions carried out in living organisms. It also focuses on the major cellular processes of breaking energy (photosynthesis and cellular respiration) and energy transformation. 

Living organisms’ organization and development focus on the role of the cell in different living organisms emphasizing cellular structures and their functions, as well as the use of microscopes in cellular studies. In addition, this part focuses on major body systems and processes in living organisms. It emphasizes the role of body systems in different living organisms in relation to the importance of the interaction between the body systems in maintaining the internal body environment. 

Content Specifications 

  • Distinguish between the four major categories of carbon compounds in terms of composition, energy values, and primary functions in the body. 
  • Relate the properties of water to its roles in living organisms.
  • Explain the role and effect of enzymes and other factors, such as pH and temperature, in the chemical reactions carried out in living organisms.
  • Identify and summarize the major cellular processes of breaking energy-rich molecules to obtain energy. 
  • Demonstrate a good understanding of handling and using the light microscope for examination purposes, and compare it with an electron microscope in terms of resolution, magnification, and use. 
  • Explain the role of the cell in different living organisms and describe the cellular processes to sustain life and maintain homeostasis. 
  • Relate the structure of major body systems in multicellular organisms to their specific functions and their interaction with each other to maintain homeostasis.

Section 2: Heredity and Genetic Technology 

This section includes the inheritance of traits and heredity and genetic technology. The Content area includes;

  • The importance of cell growth and division and explain possible outcomes when errors occur during the cell cycle. 
  • Transcription, post-transcriptional modifications, and translation, and relate these processes to gene expression in prokaryotes and eukaryotes. 
  • Use of genetic code rules to read the DNA sequence, and to identify the amino acids in the polypeptide chain. 
  • Genetic variation and explain how and why it occurs in relation to the importance of population biodiversity and stability. 
  • Understanding the role of genes in determining phenotypes and predicting offspring outcomes based on various inheritance modes, such as dominance, codominance, sex-linked, polygenic, and multiple alleles.
  • Impact of genetic engineering on medicine, industry, and agriculture, and give examples of its use.

Section 3: Evolution and Diversity of Life 

This section includes evolution and diversity of life. A major aspect of this area is determining how species evolve and the effects of natural selection and genetic drift on populations' stability based on theory and evidence of evolution. The content areas for this section also include;

  • The concepts of evolution and the investigation of different evidence to determine the evolutionary relationships among different species. 
  • Identify and explain the mechanisms by which microevolution influences allele frequencies in populations and results in macroevolution. 
  • Describe how living organisms are classified, and categorize them according to specific structural and functional characteristics. 
  • Explain the importance of and the reasons for maintaining biodiversity, and describe the threats that can lead to extinction, including the impact of human activity.

Section 4: Ecology: Interdependence, energy, and dynamics 

Ecological interdependence is discussed in this section. In addition to focusing on ecologies, it examines biogeochemical cycles, energy flow, and food chains and webs. The content areas for this section also include;

  • Differentiate between ecological concepts (e.g., biome, ecosystem, communities, habitats, niches) and provide examples of interactions between them.
  • Identify biotic and abiotic factors that affect ecosystem dynamics by understanding the interactions between organisms at different trophic levels and the flow of energy.
  • Study the impact of human activities, including density-dependent factors and density-independent factors, on carrying capacity and ecosystem dynamics.

How to Prepare for the EmSAT Biology Test?

EmSAT is the first computer-based test in the United Arab Emirates created to measure students' skills independently of the curriculum. For those planning to take the EmSAT biology exam, here are some tips on how to prepare for the EmSAT biology test: 

  • Prepare for the exam as early as possible. This will give you enough time to cover all the topics. 
  • Make a daily routine for studying.
  • Take notes while studying.
  • Study to understand, not just to memorize.
  • Go through the EmSAT biology sample question paper and answers.  
  • Practice EmSAT biology test questions with answers online
