At the base of their TAIL, there are preen glands, which secrete oil. Birds carefully apply this oil to each of their feathers. This TYPE of preening by anointing is important particularly for those that dive into the WATER to get preys, such as the Kingfisher and other water birds LIKE the Mandarin Duck.Explanation:its my pleasure to HELP you.please mark me as a brainliest

your QUESTION is not UNDERSTANDABLE!!!

but why hxExplanation:sodiumpotassiumcloride

n has more protons than electrons consequently giving it a net positive charge. For a cation to form, one or more electrons must be LOST, typically PULLED away by atoms with a stronger affinity for them. Extra points :Electrode attached to - cathode (negative) Charge - positive.

Energy technologies are the primary DETERMINANTS of energy availability, fuel CHOICE, END use efficiency, and the degree and nature of by-product emissions, and energy research and development (R&D) is the vehicle by which new technologies become AVAILABLE.

Biennials are usually sold with perennials and include sweet william, FOXGLOVE, money plant and hollyhock.please follow me and like ✌️✌️

Why is this so? Because plants and ANIMALS are not able to use NITROGEN gas in that form. For nitrogen to be AVAILABLE to make proteins, DNA, and other biologically IMPORTANT COMPOUNDS, it must first be converted into a different chemical form.

tion:DENSITY is ONE factor AFFECTING upthrust (buoyant FORCE). if the density of the substance is more than the density of the fluid, then the upthrust will be less and thus the substance SINK. if the density of the substance is less than the density of the fluid, then the upthrust will be more and thus the substance float.

Use Soil-friendly Agricultural Practices Terraces prevent EROSION and allow more water to flow to crops. In addition, hillside FARM fields need full crop cover to HELP keep the soil in place.

Volume of 1 sphere =1.76cm 3 Volume of 25 spheres =1.76×25=44cm 3 Since volume of a sphere is expressed in 3 SIGNIFICANT FIGURE, the ANSWER should have 3 significant digits=> Volume of 25 spheres =44.0cm 3

Decantation, fractional distillation, and evaporation are methods that can be used in separating the liquids like honey,WATER,coconut OIL, mustard oil and vinegar. Explanation: When the whole mixture would be KEPT still in a BEAKER, the honey, the oils, and the water would make SEPARATE

density is ONE factor affecting upthrust (BUOYANT force). if the density of the SUBSTANCE is more than the density of the FLUID, then the upthrust will be LESS and thus the substance sink. if the density of the substance is less than the density of the fluid, then the upthrust will be more and thus the substance float.

put up the point than I will you answer okkkkkkk PLEASE bro GIVE you a lot of fun and be SAFE and SOUND LIKE a good day

Before the European Union began streamlining emissions standards, there were several differing sets of rules. Members of the European Economic Community (EEC) had a unified set of rules, considerably more lax than those of the United States or Japan. These were tightened gradually, beginning on cars of over two liters displacement as the price increase would have less of an impact in this segment.[1] The ECE 15/05 norms (also known as the Luxemburg accord, strict enough to essentially require catalytic converters) began taking effect gradually: the initial STEP applied to cars of over 2000 cc in two stages, in October 1988 and October 1989.[2] There followed cars between 1.4 and 2.0 liters, in October 1991 and then October 1993. Cars of under 1400 cc had to meet two subsequent sets of regulations that applied in October 1992 and October 1994 respectively.[6] French and Italian car manufacturers, strongly represented in the small car category, had been lobbying heavily against these regulations throughout the 1980s.[7]Within the EEC, Germany was a leader in regulating automobile emissions. Germany gave financial incentives to buyers of cars that met US or ECE standards, with lesser credits available to those that partially fulfilled the requirements. These incentives had a strong impact; only 6.5 percent of new cars registered in Germany in 1988 did not meet any emissions requirements and 67.3 percent were compliant with the strictest US or ECE standards.[1]Sweden was one of the first countries to instill stricter rules (for 1975), placing severe limitations on the number of vehicles available there. These standards also caused drivability problems and steeply increased fuel consumption - in part because manufacturers could not justify the expenditure to meet specific regulations that applied only in one very small market. In 1982, the European Community calculated that the Swedish standards increased fuel consumption by 9 percent, while it made cars 2.5 percent more EXPENSIVE.[8] For 1983 Switzerland (and then Australia) joined in the same set of regulations, which gradually increased the number of certified engines.[9] One problem with the strict standards was that they did not account for catalyzed engines, meaning that vehicles thus equipped had to have the catalytic converters removed before they could be legally registered.In 1985 the first catalyzed cars entered certain European markets such as Germany. At first, the availability of unleaded petrol was limited and sales were small. In Sweden, catalyzed vehicles became allowed in 1987, benefitting from a TAX rebate to boost sales.[10] By 1989 the Swiss/Swedish emissions rules were tightened to the point that non-catalyzed cars were no longer able to be sold. In early 1989 the BMW Z1 was introduced, only available with catalyzed engines. This was a problem in some places like Portugal, where unleaded fuel was still almost non-existent, although European standards required unleaded gasoline to be "available" in every country by 1 October 1989.[11]

Having now SORTED solar, WIND, and tidal power into three “boxes,” let’s keep going and investigate another source of non-fossil energy and put it in a box. Today we’ll look at hydroelectricity. As one of the earliest renewable energy RESOURCES to be exploited, hydroelectricity is the low-hanging fruit of the renewable world. It’s steady, self-storing, highly efficient, cost-effective, low-carbon, low-tech, and offers a serious boon to WATER skiers. I’m sold! Let’s have more of that! How much might we EXPECT to get from hydro, and how important will its role be compared to other renewable resources?
