Ohm's law STATES that the electrical current (I) flowing in an circuit is proportional to the voltage (V) and inversely proportional to the RESISTANCE (R). Therefore, if the voltage is INCREASED, the current will increase provided the resistance of the circuit does not change.

Emasculation is the process of removing anthers from bisexual FLOWERS without affecting the female REPRODUCTIVE part (PISTIL), which is used in various plant hybridization techniques. Emasculation is performed by plant BREEDERS in bisexual flowers to obtain the desired variety of a plant by crossing a particular plant with the desired POLLEN grain.Explanation: Hybridization is the process of interbreeding between individuals of different species (interspecific hybridization) or genetically divergent individuals from the same species (intraspecific hybridization).

Explanation:1) Energy or Power: The whole ecosystem is undertaken from the energy of different type – solar power, man power and fuel power including electricity. But solar power is most important which is the natural energy and PROVIDES different type of driving force to all other segments-plants and man. (2) Biotic Factors: The biotic factors of the ecosystem consists of all living organisms found on the earth. These group of factors can be classified into three forms: (i) Consumers, (ii) Producers and (iii) Decomposers or Assimilators. i. Consumers: The consumers as the segments of the ecosystem depend on the plants (producers) for food and energy either DIRECTLY or indirectly. These living organisms are animals and men who belong to this category. The groups of herbivores are primary consumers who directly depend on green plants. The group of carnivores are SECONDARY consumers who indirectly depend on green plants, as they depend on herbivores for their food. Tertiary consumers are those carnivores who depend for their food on the other groups of carnivores. ii. Producers: Plants and trees are said to be the producers on the earth. They use solar energy with other nutrients from the earth and produce fresh oxygen and food for the life of animals. Plants also help to reduce the amount of CO2 in the atmosphere. These living organisms, so called producers, give some positive contribution to the ecosystem. iii. Decomposers: These living organisms-producers and consumers RELEASE a lot of waste during their life. Their dead body when they die becomes a waste on the earth. Micro organisms like bacteria, fungi, etc. play a role as a decomposer on the earth. Consuming this waste, they regenerate the energy out of the waste and back it into the ecosystem. (3) Abiotic or Physical Factors: ADVERTISEMENTS:  Abiotic or physical factors are concerned with the non-living elements found on the earth. In fact, these factors are so important to determine the life of the organisms on the different parts of the earth. These factors are described as under: i. Temperature: It is the optimally regulated temperature on the earth that has developed and supported the life on this planet. The temperature affects the metabolic activities, growth, men, animals, food habits and several other activities. Any change in the temperature which may happen over a long period of time may bring a big challenge to the support of life on the earth. ADVERTISEMENTS:  ii. Topography: The topography represents to the features or the conditions on the surface of the earth. The surface of the earth may have different kinds of features – hilly region, grassland, plateau, desert, ice-caps and plain and smooth region. The soil of the different places also varies. The variety of the soil and surface conditions of the earth determines the vegetation and the quality of life on the particular piece of land. iii. Water: A huge quantity of water is found on the earth which is stored in oceans, rivers, lakes, ponds and in side the land. Water which may be called the “drinking water” on the earth is very limited and not available to the common men. But the quality of water is most essential to the vegetation and the support of life on the earth. iv. Air: The various components of air consist of a number of gases, humidity and wind. It provides the ever important oxygen essential for the life of living organisms on the earth. All these factors determine the living conditions and the habitation pattern among human-beings. Today, air is polluted for the different reasons and the ozone layer has become THINNER, and it has affected the quality of life of the humanity and the health conditions are being deteriorating over the period. v. Light: The sun is the main source of energy and light on the earth. The plants and men use this light as an input in their photosynthesis process and produce oxygen and food which support the life on the earth. Today, the created holes in the ozone layer has permitted ultra-violet rays to enter on the earth and it has become a great challenge to the life on the earth.

There are several protozoa of MEDICAL and ECONOMIC importance. Examples include the FLAGELLATE Trypanosoma, which causes African sleeping sickness; the amoeba ENTAMOEBA HISTOLYTICA, which can attack the intestinal wall and cause amoebic dysentery, and the sporozoans of the Plasmodium species, which cause malaria.

Single Displacement ReactionsSingle displacement reactions are reactions where ONE reactant replaces part of the other:AB + C → AC + BAN example is the reaction between iron and copper sulfate to produce iron sulfate and copper:Fe + CuSO4 → FeSO4 + CuHere, both iron and copper have the same valence. One metal cation takes the place of the other, bonding to the sulfate anion.Double Displacement ReactionsDouble displacement reactions are reactions where the cations and anions in the reactants switch partners to form products:AB + CD → AD + CBAn example is the reaction between silver NITRATE and sodium chloride to form silver chloride and sodium nitrate:AGNO3 + NaCl → AgCl + NaNO3

Impurities are chemical substances inside a confined amount of liquid, gas, or solid, which differ from the chemical composition of the material or compound.Impurities are either NATURALLY occurring or added during synthesis of a chemical or COMMERCIAL product. During production, impurities may be purposely, accidentally, inevitably, or incidentally added into the substance.The LEVELS of impurities in a material are generally defined in relative terms. Standards have been established by various organizations that attempt to define the permitted levels of various impurities in a MANUFACTURED product. Strictly speaking, then a material's level of purity can only be stated as being more or less pure than some other material.HOPE IT HELPED U....I don't know guyz.. why u report the questions?????

In astronomy, Kepler's laws of planetary motion are three scientific laws describing the motion of planets around the Sun, PUBLISHED by Johannes Kepler between 1609 and 1619. The laws state that:1) The orbit of a planet is an ellipse with the Sun at one of the TWO foci.2) A line segment joining a planet and the Sun sweeps out equal areas during equal intervals of time.3) The square of the ORBITAL period of a planet is directly proportional to the cube of the semi-major axis of its orbit.The elliptical orbits of planets were indicated by calculations of the orbit of Mars.[3] From this, Kepler inferred that other bodies in the Solar System, including those farther away from the Sun, also have elliptical orbits. The second law helps to ESTABLISH that when a planet is closer to the Sun, it travels FASTER. The third law expresses that the farther a planet is from the Sun, the longer its orbit, and vice versa.Hope it helps....✌Please mark Brainliest if you can ;)

Specifically, plants use energy from sunlight to react CARBON dioxide and WATER to produce sugar (glucose) and oxygen. MANY reactions occur, but the OVERALL chemical reaction for photosynthesis is: 6 CO2 + 6 H2O + light → C6H12O6 + 6 O. Carbon Dioxide + Water + Light yields Glucose + Oxygen.

The sugar would dissolve in water. You could then pour off the solution and wash the remaining sand with a bit more water. Heat the water to evaporate it from the sugar, and the two are SEPARATED. Because you have not altered the sand or the sugar in a chemical way (the sugar ALWAYS remains as sugar, and is RECLAIMED in the same form), these were PHYSICAL changes.

tion:The microorganisms that break it down can cause disease and produce HARMFUL gases. Non-biodegradable materials are often synthetic products like plastic, GLASS and batteries. Because they don't break down EASILY, if not DISPOSED of properly, non-biodegradable waste can cause pollution, block drains and HARM animals.

A parasitic plant is a plant that derives some or all of its nutritional requirement from another living plant. They make up about 1% of ANGIOSPERMS and are found in almost every biome. All parasitic plants have MODIFIED roots, called haustoria, which penetrate the host plant, CONNECTING them to the conductive system – either the xylem, the phloem, or both. For example, plants like STRIGA or Rhinanthus connect only to the xylem, via xylem bridges (xylem-feeding). Alternately, plants like Cuscuta and Orobanche connect only to the phloem of the host (phloem-feeding).[1][2] This provides them with the ability to extract water and nutrients from the host. Parasitic plants are classified depending as to the location where the parasitic plant latches onto the host and the amount of nutrients it requires.[3] Some parasitic plants are able to locate their host plants by detecting CHEMICALS in the air or soil given off by host shoots or roots, respectively. About 4,500 species of parasitic plant in approximately 20 families of flowering plants are known.[4][3hope it helps
