Viruses have their own peculiarities. They are a group of very simple and very small organisms, which consists of a strand of nucleic acid surrounded by a coat of protein. All are now known as parasites, which are capable of reproducing in the living cells of host animal, plant, or microorganism. They cannot be cultivated on artificial media as many bacteria can. These peculiarities, together with the production of crystal like forms, are unusual in living organisms and have led some investigators to regard viruses as lying athwart the line dividing the inanimate from the animate. 1.  A virus can be cultured in an artificial media to study its life cycle. a.

Photosynthesis   10.  In plants the solar energy is trapped and converted into chemical bond energy through photosynthesis by: a. Leucoplast b. Chlorolast c. Chromoplast d. Chloroplast     This Question is based on the following passage:   Mitochondria are membrane-bound organelles, and like the nucleus have a double membrane. The outer membrane is fairly smooth. But the inner membrane is highly convoluted, forming folds called cristae. The cristae greatly increase the inner membrane's surface area. It is on these cristae that food (sugar) is combined with oxygen to produce ATP - the primary energy source for the cell. Mitochondria's main role is the production of ATP (adenosine tri-phosphate) which is the principal energy storage molecule of the cell (it is also a component for the synthesis of nucleic acids (RNA and DNA) and it can act as a neurotransmitter) ATP is produced in the electron transport chain which uses products of the Krebs cycle which is itself linked to the metabolism of sugars, fats and amino acids. Mitochondria contain their own DNA which codes for some but not all the proteins found in mitochondria. It is believed that originally mitochondria were independent organisms that early on in evolutionary history have entered a symbiotic relationship with unicellular organisms. Mitochondria are inherited only through the mother line (the sperm does not contribute mitochondria to the egg) 11.  What is the similarity between a mitochondrion and  nucleus? a. Both are bound with a double membrane b. Both produce ATP c. Both have DNA d.

Any group of living and nonliving things interacting with each other can be considered as an ecosystem. In an ecosystem, the food relation in its simplest form, representing a producer, primary consumer, a secondary consumer and decomposer, is called a food chain. Within each ecosystem, there are habitats which may also vary in size. A habitat is the place where a population lives. A population is a group of living organisms of the same kind living in the same place at the same time. All of the populations interact and form a community. The community of living things interacts with the non-living world around it to form the ecosystem. The habitat must supply the needs of organisms, such as food, water, temperature, oxygen, and minerals. If the population's needs are not met, it will move to a better habitat. Two different populations can not occupy the same niche at the same time, however. So the processes of competition, predation, cooperation, and symbiosis occur. 14.  What is each step in a food chain called? a. Trophic Stage b. Trophic Grade c. Trophic level d.

Fungi and Bacteria     This Question is based on the following passage:   Hormones in animals coordinate body functions by being produced in one place and acting in another. This would be true for animal hormones but plant hormones are often produced in the structure or tissue in which they act. Plants do not have a circulatory system and "action at a distance" may not be a feature of plant hormones. Plant hormones seem to coordinate growth and development in different parts of the plant, and help the plant respond to environmental signals. They are molecules that are not directly involved in metabolic or developmental processes but they act at low concentrations to modify those processes. There are five generally recognized classes of plant hormone. They are auxins, cytokinins, ethylene, abscisic acid and gibberlins. Some of the classes are represented by only one compound, others by several different compounds. They are all organic compounds, they may resemble molecules which turn up elsewhere in plant structure or function, but they are not directly involved as nutrients or metabolites. 18.  Plants do not have which of the following? a.

Photosynthesis and respiration are complementary processes in the living world. Photosynthesis uses the energy of sunlight to produce sugars and other organic molecules. These molecules in turn serve as food for other organisms.

The sequence and properties of side chains determine all that is unique about a particular protein, including its biological function and its specific three-dimensional structure. 45.  Gametes are generated as a result of which kind of cell division? a. Meiosis b. Mitosis c. Photosynthesis d. Phosphorylation     This Question is based on the following passage:    Proteins make up about 15% of the mass of the average person. Protein molecules are essential to us in variety of different ways. Much of the fabric of our body is constructed from protein molecules. Muscle, cartilage, ligaments, skin and hair - these are all mainly protein materials.

Bat- Mammalia b. Amoeba- Protozoa c. Lizard- Arthropoda d. Crocodile - Reptilia     This Question is based on the following passage:   Hardy Weinberg equilibrium- Hardy-Weinberg equilibrium describes a state in which genotype frequencies are constant from generation to generation and in which genotype frequencies are a product of allele frequencies. This condition prevails in situations in which there are an absence of mutations, migrations, non-random mating and environmental factors favoring particular genotypes. In a paper published in 1908, G. H. Hardy sought to disprove the Mendelian idea that dominant genetic characteristics would tend to appear in the whole population, while recessive characteristics would tend to disappear. A population is a set of interbreeding individuals all belonging to the same species. In most sexually reproducing species, including humans, each organism contains two copies of virtually every gene—one inherited from each parent. Any particular gene may occur in slightly different forms, called alleles. An organism with two identical alleles is called homozygous for that gene, and one with two different alleles is called heterozygous. During the formation of gametes, the two alleles separate into different gametes. 53.  What is a set of interbreeding individuals all belonging to the same species called? a. Pollution b.
