Gene Regulation Quiz
Regulation of gene expression, or gene regulation,includes a wide range of mechanisms that are used by cells to increase or decrease the production of specific gene products (protein or RNA). Sophisticated programs of gene expression are widely observed in biology, for example to trigger developmental pathways, respond to environmental stimuli, or adapt to new food sources.

DNA as the Genetic Material Quiz
Deoxyribonucleic acid is a molecule composed of two polynucleotide chains that coil around each other to form a double helix carrying genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses. DNA and ribonucleic acid are nucleic acids.

Photosynthesis Quiz
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms' activities. This chemical energy is stored in carbohydrate molecules, such as sugars, which are synthesised from carbon dioxide and water

Classical and Molecular Genetics
Molecular genetics is a sub-field of biology that addresses how differences in the structures or expression of DNA molecules manifests as variation among organisms. Molecular genetics often applies an "investigative approach" to determine the structure and/or function of genes in an organism’s genome using genetic screens. The field of study is based on the merging of several sub-fields in biology: classical Mendelian inheritance, cellular biology, molecular biology, biochemistry, and biotechnology. Researchers search for mutations in a gene or induce mutations in a gene to link a gene sequence to a specific phenotype. Molecular genetics is a powerful methodology for linking mutations to genetic conditions that may aid the search for treatments/cures for various genetics diseases.

Cellular Respiration Quiz
Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules or nutrients into adenosine triphosphate (ATP), and then release waste products. The reactions involved in respiration are catabolic reactions, which break large molecules into smaller ones, releasing energy because weak high-energy bonds, in particular in molecular oxygen, are replaced by stronger bonds in the products.

Membranes and Transport Quiz
The cell membrane is also known as the plasma membrane. It is the outermost covering of animal cells. It is a semi-permeable membrane composed of lipids and proteins. The main functions of the cell membrane include: Protecting the integrity of the interior cell. Providing support and maintaining the shape of the cell. Helps in regulating cell growth through the balance of endocytosis and exocytosis. The cell membrane also plays an important role in cell signalling and communication. It acts as a selectively permeable membrane by allowing the entry of only selected substances into the cell.

Structure of a Cell Quiz
Cells are the structural, functional, and biological units of all living beings. A cell can replicate itself independently. Hence, they are known as the building blocks of life. Each cell contains a fluid called the cytoplasm, which is enclosed by a membrane. Also present in the cytoplasm are several bio molecules like proteins, nucleic acids and lipids. Moreover, cellular structures called cell organelles are suspended in the cytoplasm.

Energy and Enzymes Quiz
In biology, energy is often stored by cells in bio molecules, like carbohydrates (sugars) and lipids. The energy is released when these molecules have been oxidized during cellular respiration. The energy released from them when they are oxidized during cellular respiration is carried and transported by an energy-carrier molecule called ATP.Enzymes are biological molecules (typically proteins) that significantly speed up the rate of virtually all of the chemical reactions that take place within cells. They are vital for life and serve a wide range of important functions in the body, such as aiding in digestion and metabolism.

Macro Molecules Quiz
A macro molecule is a very large molecule, such as protein, commonly composed of the polymerization of smaller subunits called monomers. They are typically composed of thousands of atoms or more. The most common macromolecules in biochemistry are biopolymers (nucleic acids, proteins, and carbohydrates) and large non-polymeric molecules (such as lipids and macrocycles). synthetic fibers as well as experimental materials such as carbon nanotubes.

Immune System In Bio science Quiz Test
Play quiz on Immune System In Bioscience, In biology, immunity is the balanced state of multicellular organisms having adequate biological defenses to fight infection, disease, or other unwanted biological invasion, while having adequate tolerance to avoid allergy, and autoimmune diseases.
What is immunity immunity type?
Two types of immunity exist — active and passive: Active immunity occurs when our own immune system is responsible for protecting us from a pathogen. Passive immunity occurs when we are protected from a pathogen by immunity gained from someone else

Biochemistry Quiz Biology
Biochemistry, sometimes called biological chemistry, is the study of chemical processes within and relating to living organisms.[1] Biochemical processes give rise to the complexity of life.
Biochemistry is the branch of science that explores the chemical processes within and related to living organisms. It is a laboratory based science that brings together biology and chemistry. By using chemical knowledge and techniques, biochemists can understand and solve biological problems.

Chromosomes And Recombination Quiz
Most recombination is naturally occurring. During meiosis in eukaryotes, genetic recombination involves the pairing of homologous chromosomes. This may be followed by information transfer between the chromosomes. ... In meiosis and mitosis, recombination occurs between similar molecules of DNA . In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes

Human Anatomy/Osteology/Skull Quiz
Skull Anatomy Quiz Test. Before starting the quiz about skull-anatomy, couple of things needs to be discussed. The English word "skull" is probably derived from the Old Norse "skulle", while the Latin word cranium comes from the Greek root κρανίον (kranion). To make the definition easy to understand- The skull is a bony structure that forms the head in vertebrates. It supports the structures of the face and provides a protective cavityfor the brain. The skull is composed of two parts one of them is the cranium and another one is mandible. In humans, these two parts are the neurocraniumand the viscerocranium or facial skeleton that includes the mandible as its largest bone. The skull forms the anterior-most portion of the skeleton and is a product of cephalization-housing the brain, and several sensory structures such as the eyes, ears, nose, and mouth. In humans, these sensory structures are part of the facial skeleton. Functions of the skull include protection of the brain, fixing the distance between the eyes to allow stereoscopic vision, and fixing the position of the ears to enable sound localization of the direction and distance of sounds. In some animals such as horned ungulates, the skull also has a defensive function by providing the mount (on the frontal bone) for the horns. The skull is made up of a number of fused flat bones and contains many foramina, fossae, processes, and several cavities or sinuses. In zoology, there are openings in the skull called fenestrae. Now it’s time to answer those quizzes.
