Explanation:
Ans 3) In linguistics, coordination is a complex syntactic structure that links together two or more elements; these elements are called conjuncts or conjoins. The presence of coordination is often signaled by the appearance of a coordinator, e.g. and, or, but.
Ans 4) Vascular tissue is a complex conducting tissue, formed of more than one cell type, found in vascular plants. The primary components of vascular tissue are the xylem and phloem. These two tissues transport fluid and nutrients internally.
Ans 5) A product excreted by a living organism or cell.
Ans 6)The main role of DNA in the cell is the long-term storage of information. It is often compared to a blueprint, since it contains the instructions to construct other components of the cell, such as proteins and RNA molecules.
Ans 7) Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from parents to offspring, DNA contains the specific instructions that make each type of living creature unique.
Ans 8) Prokaryotes are organisms that consist of a single prokaryotic cell. Eukaryotic cells are found in plants, animals, fungi, and protists. They range from 10–100 μm in diameter, and their DNA is contained within a membrane-bound nucleus. Eukaryotes are organisms containing eukaryotic cells.
Ans 9) These include food, water, air, soil and others. Biotic components are the living agents which also influence the life cycle of other living beings. Abiotic components like air is necessary for respiration. Food is necessary for growth.
Ans 10)The cell is the smallest structural and functional unit of living organisms, which can exist on its own. Therefore, it is sometimes called the building block of life. Some organisms, such as bacteria or yeast, are unicellular—consisting only of a single cell—while others, for instance, mammalians, are multicellular.
Ans 11) The various organs and organ systems are separated from each other through the connective tissues. - All the organs combine up together to perform specific tasks in our body.
Ans 12) a unit of astronomical distance equivalent to the distance that light travels in one year, which is 9.4607 × 1012 km (nearly 6 million million miles).
Ans 13) The sky is the region in which sunlight is scattered in the Earth's atmosphere, making it visible from the surface of the planet, while space is everything beyond that. The sky also includes all objects as far as we can see outside of the Earth. For example, Mars is far away but we consider it in our night sky.
Ans 14) The scientific observations on the different circumstances happening in the outer space with the help of modern science and technology is known as the space observation. ... - There are many threats which can come from the outer space and negatively affect our planet,such as meteoroid,space radiation and many more.
Ans 15) Satellite television is a service that delivers television programming to viewers by relaying it from a communications satellite orbiting the Earth directly to the viewer's location.[1] The signals are received via an outdoor parabolic antenna commonly referred to as a satellite dish and a low-noise block downconverter.
