There is 30 Sec for each question. Students preparing for SSC, BANKING, RAILWAY, or any other competitive exams, can attempt this quiz. 1 / 15 A cockroach has Three pairs of walking legs Two pairs of walking legs Four pairs of walking legs One pair of walking legs 2 / 15 Which of the following branches of science is concerned with the study of the relationship of plants to their environment? Cytology Ecology Morphology Physiology The branch of biology that deals with relationships between organisms and their environments is called ecology. 3 / 15 The basic unit of all living organisms is A drop of blood A molecule of glucose A set of proteins Non of these. Cells are called as the basic unit of life because all the living organisms are made up of cells and also all the functions taking place inside the body of organisms are performed by cells. Cells provide the specific conditions, for the occurrence of the metabolic reactions. 4 / 15 Bacteria do not need sunlight to grow because They lack chlorophyll and so they are incapable of making their own food They hate sunlight They use other kinds of light for their food synthesis They prepare their food without the help of sunlight Chemosynthetic bacteria do not need sunlight to grow because. They do not like sunlight brightness. They prepare their food without the help of light. Due to absence of chlorophyll they are incapable of manufacturing their own food. 5 / 15 Movements due to light are shown by Flowering plants Lower plants All land plants All the plants The flowering plants are plants that produce flowers as their main characteristics. However, these plants move towards the light source. This movement is a type of response that is called phototropism. 6 / 15 Most viruses that infect plant possess single-stranded DNA single-stranded RNA double-stranded DNA and RNA double – stranded RNA only Viruses contain either RNA or DNA as the genetic material and never both. In general, viruses that infect plants have single stranded RNA (ssRNA) while those that infect animals may have either single or double stranded RNA (ssRNA or dsRNA) or double stranded DNA (dsDNA). 7 / 15 Which of the following is the basic characteristic of a living organism? Ability to move Ability to reproduce Ability to eat Ability to breathe Reproduction: A biological process that ensures the survival of a species and genetic material between generations. 8 / 15 Which is regarded as a link between the living and the non-living? Amoeba Virus Bacteria RNA Viruses are connecting links between living and nonliving organisms. An organism is called a connecting link when it possesses characters of two different organisms. 9 / 15 In human body, the cell growth and differentiation are highly controlled and regulated, but in cancer cells. there is breakdown of these regulatory mechanism leading to formation of benign and malignant tumors controlled cell division and over production of genetic material occur RNA is mutated and produced in less amount DNA is mutated and produced in less amount In the human body, cell growth and differentiation are tightly regulated processes. This means that cells divide and specialize in a controlled manner, allowing the body to grow and function properly. However, in cancer cells, these regulatory mechanisms break down, leading to the formation of tumors. 10 / 15 Man has become the dominant species in the biosphere because of his Tool-making capacity Ingenious brainpower Articulated speech and language All the above mentioned qualities 11 / 15 A ‘clinical death’ takes place when There is no pulse There is no heart beat Pupils are fixed and dilated, and there is no reaction to light All the above three conditions are present together 12 / 15 Crows and pigeons are Warm-blooded Cold-blooded Neither (a) nor (b) Both (a) and (b) 13 / 15 All the following are invertebrates except Snail Crab Prawn Fish 14 / 15 Bacteria reproduce By sexual method only By asexual method only Mostly by sexual method Mostly by asexual method 15 / 15 The main difference between the living and non-living is in the growth in the size in the movement in the presence of protoplasm Your score isThe average score is 31% 0% Restart quiz
