Esta questão está relacionada com a proporcionalidade entre variáveis. A proporção é um valor referente a razão de dois números. Por isso, a proporção está atrelada a fração, onde temos um numerador e um denominador. Desse modo, temos uma relação de equivalência entre dois valores.

Nesse caso, vamos resolver o problema por meio da semelhança entre triângulos. A semelhança entre triângulos ocorre quando existem dois ou mais triângulos com mesmos ângulos internos. Desse modo, existe uma proporção entre suas medidas, que devem ser equivalentes sobre uma determinada razão. Portanto:

what are the ways to conserve soil erosion​

Answers

afforestationconstruction of damschecking overgrazechanging agriculture practices

Answer:

-Maintaining a healthy, perennial plant cover.

-Mulching.

-Planting a cover crop – such as winter rye in vegetable gardens. Includes annual grasses, small grains, legumes and other types of vegetation planted to provide a temporary vegetative cover. Cover crops are often tilled under serving also as a “green manure” crop.

-Placing crushed stone, wood chips, and other similar materials in heavily used areas where vegetation is hard to establish and maintain.

Explanation:

Soil erosion is a concern not only for its impacts on plant growth, but also for its impacts to water quality. Soil is a valuable natural resource that nourishes and supports plant growth among many other things. When soil is left bare and exposed, wind and water can erode it.

Sediments that are transported to storm drains and surface waters can choke aquatic life and increase water temperatures. Various pollutants such as bacteria, nutrients and heavy metals may also be attached to these sediments, further degrading water quality.

difference and similarity between biodiversity at local, regional and global ​

Answers

Answer:

The “fact” that biological diversity—biodiversity—is declining and that humanity is ultimately responsible has become common knowledge among scientists, citizens, and policymakers. Biodiversity loss is the mantra for conservation; we are exhausting biodiversity on the planet at a far greater rate than it can replenish itself (1). Furthermore, these losses could greatly reduce the benefits (ecosystem services) that humans obtain from nature, such as the pollination of crops, absorption of carbon dioxide from the atmosphere, and provision of wild foods . However, is biodiversity truly declining? Remarkably, Vellend et al. export that, on average, the local diversity of plants has not decreased in recent decades. If anything, it has increased.

Vellend et al. searched the literature for studies that examined changes in local plant diversity. They found 168 studies from around the world, where the number of plant species had been counted, in over 16,000 plots in total, over periods of 5–50 or more years. They analyzed their global-scale dataset, finding an average 7.6% increase per decade in the number of species present in plots. This average was not significantly different from zero, so they concluded that there has been no overall change in local plant diversity, a finding that is extremely interesting.

What is gdp and how is it useful

Answers

Answer:

Gross domestic product (GDP) is a monetary measure of the market value of all the final goods and services produced in a specific time period. GDP (nominal) per capita does not, however, reflect differences in the cost of living and the inflation rates of the countries; therefore, using a basis of GDP per capita at purchasing power parity (PPP) may be more useful when comparing living standards between nations, while nominal GDP is more useful comparing national economies on the international market. Total GDP can also be broken down into the contribution of each industry or sector of the economy. The ratio of GDP to the total population of the region is the per capita GDP and the same is called Mean Standard of Living.
