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.
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.
|(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
EmSAT achieve biology provides a valuable assessment of student learning, it is also used as one of several factors in determining course placement in Emirates.
|High Proficiency: students at this level are well-prepared for biology courses at the university level
|Proficient: students at this level are at a satisfactory level of preparation to begin first-year biology courses at the university level.
|Borderline Proficient: students at this level are minimally prepared for first-year biology courses at the university level.
|Basic: students at this level do not have sufficient mastery of prerequisite knowledge for first-year courses in biology at the university level, and may need some additional support
|Needs improvement: students at this level need instructions in basic biological concepts and skills before beginning any first-year biology courses.
|Little knowledge of general biology: students at this level need intensive instructional support in basic biological concepts and skills.
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.
This section includes the inheritance of traits and heredity and genetic technology. The Content area includes;
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;
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;
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:
D. A and B
A. The mass has increased because water potential of the cells has decreased.
B. The mass has decreased because water potential of the cells has increased.
C. The mass has increased because water potential of the solution has decreased.
D. The mass has decreased because water potential of the solution has increased.

4. The following graph represents the different phases of the cell cycle in which the X-axis represents the amount of DNA and the Y-axis represents the number of cells. At which phase of the cell cycle are the C population of cells?
B. S phase
C. G1 phase
5. The chart below shows the mRNA codons for different amino acids?
Given the following codon sequence.
5’ AUG UCU UAC CUG GCU CGG … UAA 3’
Which of the following can be described as base substitution causing a nonsense mutation in the mRNA sequence below?
A. Substitution of UAC for UAU in the third codon
B. Substitution of UAC for UCC in the third codon
C. Substitution of UAC for UAA in the third codon
D. Substitution of UAC for UGC in the third codon
6. The following pedigree represents the inheritance of an autosomal recessive syndrome in a family.
If the affected male in generation II marries a normal female who is homozygous for the trait, what is the possibility to have an affected child?
7. All of the following steps occur when subpopulations speciate, EXCEPT
A. natural selection divides a population into two or more, forcing them to differentiate.
B. isolated subpopulations adapt to local conditions through natural selection.
C. once the two divergent subpopulations meet again, hybrids will always occur.
D. active selection on differentiated subpopulations to become reproductively isolated
8. Cystic fibrosis is a chronic and frequently fatal genetic disease of the body’s mucus glands. It is caused by an autosomal recessive mutation. In the European population, one out of approximately 10,000 babies is born with the disorder. What is the frequency of the cystic fibrosis allele in the European population assuming the Hardy-Weinberg conditions are met?
9. A scientist is studying the phylogeny of 4 species (species 1, 2 3, and 4). To this end, she sequenced a fragment of DNA and she obtained the following alignment:
Species 1 A A T C G G A
Species 2 C A G G T A C
Species 3 A A T C T G A
Species 4 C A T G T G C
Using this alignment, she constructed a phylogenetic tree using the parsimony method (a method that minimizes the number of changes on a phylogeny).
Which of the 4 phylogenetic trees below is supported by the DNA sequences?
A. Tree A
B. Tree B
C. Tree C
D. Tree D
10. The ecological relationship between two different species are shown in the graph below.
What ecological relationship does the graph represent?
11. The diagram below represents a food web in an ecosystem.

A. The prey populations of hawks might decrease. Later the hawk population might remain unchanged.
B. The prey populations of hawks might decrease. Later, the hawk population might increase.
C. The prey populations of hawks might decrease, Later, the other populations in the web might decrease.
D. The prey populations of hawks might decrease. Later, the hawks would find another prey population.
12. All of the following could be considered density-dependent factors affecting population growth EXCEPT
A. Climate temperature
B. Limited nutrients
C. Build-up of toxins
