Evening Biology Model with Solution 2024

The AMSAT Biology exam is one of the most popular tests in the UAE for university admission. This exam aims to assess students’ knowledge, understanding and abilities in the field of life sciences. The exam is designed to test a variety of concepts and skills learned over the specified time period. The questions in the exam vary to measure their ability to apply them in different contexts. The exam may include a set of different questions such as practical and theoretical questions and multiple choice questions. One of the things that are focused on is biological classification, where students are asked to classify a specific group of living organisms and explain the relationships between them. The exam also includes questions about the structure of cells and the functions of their different parts.

In addition, the focus is on environmental and sustainability topics and questions related to the impact of human activities on the environment and possible measures to preserve biodiversity and sustainability. One of the important aspects of the exam is the ability to analyze and think critically. Scenarios and problems are included that students have to solve using biological concepts and apply them in practical life. In addition, comprehensive conclusions and interpretations of the results and data presented in the questions are required. Students must wait for the exam results, which will be a clear indication of their level of understanding and performance in the field of biology. Regardless of the final results, students should be proud of their efforts and diligence in preparing for the exam and interacting with the study materials.

10. What is the role of DNA in cells?

Answer : The role of DNA in cells DNA is the main genetic material in cells, as it contains the genetic information that determines the hereditary traits of living organisms. This information is stored in a specific sequence of nitrogenous bases in the DNA duplex ladder. DNA directs the processes of growth, development, and cellular functions by converting information into genetic messages and directing cellular activity based on these messages.

Answer: It is the process by which living organisms use the energy contained in food materials to achieve vital functions, growth and development. Metabolism includes two main processes: entropic metabolism (decomposition) and anabolic metabolism (building).

  1. Explain the concept of evolution and how it happens?

Answer: It is the gradual change in the characteristics of living organisms from generation to generation due to environmental pressures and genetic adaptations. Evolution is represented by changes in the composition of genes and hereditary traits across generations, which leads to changes in the composition, behavior, and adaptation of organisms to the environment.

Answer: Meiosis: The process of cell division that produces two cells with the same number of chromosomes as the parent cell. Meiosis occurs in somatic (body) cells and includes branching division (simple duplication) and contractile division (cell division).

Meiosis: A process of cell division that produces two daughter cells with different numbers of chromosomes. Meiosis occurs in gametes (corolla) and involves a single reproductive phase that results in the formation of gametes.

  1. What is the difference between a plant cell and an animal cell?

Answer: - Plant cell:

- It contains an outer cell wall that gives it support and protection.

- It contains chloroplasts that carry out photosynthesis to convert sunlight into chemical energy.

- They can vary greatly in size and shape, including long cells such as the cells of the transition tissue in leaves.

- Animal cell:

- It does not contain a cell wall, but is surrounded by a cell membrane.

- Does not contain chloroplast.

Their shapes are more varied between species, but they are often smaller than plant cells.

  1. What are the main organs in the digestive system and what are the functions of each?

Answer: Examples of the main organs in the digestive system and the functions of each:

- Stomach: It digests food, analyzes it, and converts it into absorbable substances.

- Small intestine: It is responsible for the effective absorption of nutrients and important nutrients into the bloodstream.

- Large intestine: absorbs water and salts, forms waste and excretes it from the body.

  1. What is the role of chlorophyll in plants?

Answer: The role of chlorophyll in plants:

Chlorophyll is the green pigment responsible for the green color in plants, and is the molecule that absorbs sunlight to carry out photosynthesis. When light is absorbed, it is converted into chemical energy that can be used in the process of energy storage and the production of organic matter.

  1. What is the importance of ecological balance and how can we contribute to preserving it?

Answer: - Ecological balance refers to maintaining the balance of different ecosystems, including biological, chemical and physical systems, to ensure the sustainability of life on Earth.

The importance of environmental balance includes preserving biological diversity, providing natural resources for living organisms, and providing suitable conditions for life and growth.

- You can contribute to preserving the ecological balance by:

- Raising awareness of the importance of the environment and the need to preserve it.

- Adopting sustainable practices such as saving natural resources and reducing waste.

- Support efforts to protect the environment, including preserving natural spaces and combating pollution.

- Participation in local and international activities and initiatives aimed at preserving the environment and promoting sustainable development.

  1. What are the differences between photolysis and pyrolysis?

Answer: Differences between photolysis and pyrolysis:

- Photolysis:

- It is the process of converting light into chemical energy, which is the process in which green organisms (such as plants) use sunlight to carry out photosynthesis.

- It occurs in the chloroplast inside plant cells.

- Pyrolysis:

It is the process of converting chemical energy into thermal energy, and it is the most common type of decomposition in living organisms.

- It occurs in all living organisms as part of cellular metabolic processes, where food compounds are broken down to release the chemical energy stored in them.

  1. What are the four main tissues in the human body and what are the functions of each?

Answer: The four main tissues in the human body and the functions of each:

Structural tissues: include epithelial tissue (skin), connective tissue (bone and connective tissue), muscular tissue (muscles), and nervous tissue (nerves).

- Functions of each:

- Epithelial tissue: provides protection for internal organs and controls the exchange of materials with the external environment.

Connective tissue: Provide structural support and provide a place for other tissues to grow and develop.

Muscle tissue: generates movement, reduces stress, and pushes blood and nutrients through the body.

Nervous tissue: transmits electrical and chemical signals in the body and regulates vital functions.

20. The main function of enzymes in living organisms is:

- a) Energy storage
