what is cell address?in how many ways a cell address can be given? |
| Answer» <p>Ans :- The cell ADDRESS function is categorized underLookup and Reference functions. It will provide a cell reference (it’s “address”) by taking the row number and column letter. The cell reference will be provided as a string of text. The function can return an address in a relative or absolute format and can be used to construct a cell reference inside a formula.</p><p>As afinancial analyst, cell ADDRESS can be used to convert a column number to a letter, and vice versa. We can use the function to address the first cell or last cell in a range.</p><p>Formula</p><p>=ADDRESS(row_num, column_num, [abs_num], [a1], [sheet_text])</p><p>The formula uses the following arguments:</p><p>Row_num(required argument) – It is a numeric value specifying the row number to be used in the cell reference.</p><p>Column_num(required argument) – It is a numeric value specifying the column number to be used in the cell reference.</p><p>Abs_num(optional argument) – It is a numeric value specifying the type of reference to return:</p> | |

how blood flows in heart |
| Answer» <p>How Does Blood Flow Through the Heart?</p><p>The right and left sides of the heart work together. The pattern described below is repeated over and over, causing blood to flow continuously to the heart, lungs, and body.</p><p>Right side of the heart</p><p>Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium.</p><p>As the atrium contracts, blood flows from your right atrium into your right ventricle through the open tricuspid valve.</p><p>When the ventricle is full, the tricuspid valve shuts. This prevents blood from flowing backward into the right atrium while the ventricle contracts.</p><p>As the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs, where it is oxygenated. The oxygenated blood then returns to the heart through the pulmonary veins.</p><p>Left side of the heart</p><p>The pulmonary veins empty oxygen-rich blood from the lungs into the left atrium.</p><p>As the atrium contracts, blood flows from your left atrium into your left ventricle through the open mitral valve.</p><p>When the ventricle is full, the mitral valve shuts. This prevents blood from flowing backward into the atrium while the ventricle contracts.</p><p>As the ventricle contracts, blood leaves the heart through the aortic valve, into the aorta and to the body.</p> | |

(1)Epiphytic roots (2) Sucking roots.(L.A.) |
| Answer» <p>(1) The orchids (of family Orchidaceae-monocotyledons) are epiphytes. They possess the aerial roots hanging in the air.The velamen consists of several layers of dead cells often with spirally thickened and perforated walls, which act as sponge, soaking up water that runs over it. The velamen is multiple epidermis. The velamen is thought to function as a protective tissue, preventing undue water loss from the delicate cortical cells of the exposed aerial root.</p> <p>(2) Sucking Roots These are the rootsof parasites. The parasites penetrate the small adventitious rootlets into the tissues of the host so that there is connection between the conducting systems of the two plants. This is the channel through which food is sucked in by the parasite from the host. Such sucking roots or haustoria are found in many total and partial parasites.</p> | |

far from us?9. Explain why there is a need of variety of animals and plants in a forest.17 10 the artist has forgotten to put the labels and directions on |
| Answer» <p>The variety of plants and animals are needed to maintain a balance in the ecosystem. The herbivores eat different types of plants. But to avoid extinction of plants, there are carnivores who eat herbivores. The nature controls the balance by introducing various species. There are plants which depend on one another for nutrients and live in a symbiotic relationship. If this was not the case, Earth would have been a barren land with no species.</p> <p>What means Reflection of Light </p> | |

Answer the following questions in aboutName the factors that determine the weather of a placeand briefly explain their role.a.ur during the day? |
| Answer» <p>There are many factor that influence weather,The Water CycleAs the sun warms the surface of the Earth, water rises in the form of water vapor from lakes, rivers, oceans, plants, the ground, and other sources. This process is called evaporation.</p><p>Water vapor provides the moisture that forms clouds; it eventually returns to Earth in the form of precipitation, and the cycle continues.</p><p>Air MassesWhen air hovers for a while over a surface area with uniform humidity and temperature, it takes on the characteristics of the area below. For example, an air mass over the tropical Atlantic Ocean would become warm and humid; an air mass over the winter snow and ice of northern Canada would become cold and dry. These massive volumes of air often cover thousands of miles and reach to the stratosphere. Overtime, mid-latitude cyclonic storms and global wind patterns move them to locations far from their source regions.Jet StreamA jet stream is the name given to the area of air above where two air masses of different temperature converge e.g. a cold front meeting a warm front. The greater the temperature difference between the air masses, the greater the air pressure difference, and the faster the wind blows in the jet stream. This river of air has wind speeds which often exceed 100 mph, and sometimes over 200 mph. Jet streams more commonly form in the winter, when there is a greater difference between the temperature of the cold continental air masses and warm oceanic air masses.</p> | |

How water can be helpful for agricultural need? |
| Answer» <p>Since the 1960s the global nutrition has considerably improved, providing more food per capita at progressively lower prices. This performance was possible through high-yielding seeds, irrigation and plant nutrition. As population keeps increasing more food and livestock feed need to be produced in the future and more water applied to this purpose. Irrigate agriculture will have to claim large quantities of water to produce the food required to feed the world. The main source of food for the population of the world is agriculture: this term also includes livestock husbandry, manages fisheries and forestry.</p><p>The composition of meals changes gradually as lifestyles change. What agriculture produces is driven by consumer demand, and changes in consumer preferences have an influence on the water needed for food production.</p> | |
