Answer:
a system whereby the government undertakes to protect the health and well-being of its citizens, especially those in financial or social need, by means of grants, pensions, and other benefits. The foundations for the modern welfare state in the US were laid by the New Deal programs of President Franklin D. Roosevelt.

Answer:
Las dos técnicas utilizadas para restaurar la biodiversidad son la biorremediación y el aumento biológico.
Explanation:
If a species cannot reproduce then it will die out. This depends on the climatic conditions of the region. If there is a natural disaster, for example, it will affect a species' ability to reproduce. This reduces the number of diverse species on earth. Biodiversity is the recognised variety of different types of life found on the earth. It also measures the variety of number and variety of plants, animals and other organisms found in different ecosystems.
Explanation:
Since the 2 species co-inhabit a similar home ground, home ground isolation will be forgotten as an element keeping the 2species separate. There are but another broad class of mechanisms for reproductive isolation. One is behaviour. several birds specifically have terribly specific coupling rituals, together with coupling dances, specific birdsong, the event of specific coupling animal material, the discharge of specific pheromones and the building of a selected nest structure. Another broad class is mechanical isolation. you'll notice that the reproductive organ organs of specific species are terribly specific, and preclude different shut species from with success coupling. Another broad class is gametic isolation. for many species combos, it's inconceivable for the gametes to fuse with success to make a hybrid. If hybrid games do fuse, in several cases, the hybrids sterile, like mules as an example.
Answer: Coal is primarily used as fuel to generate electric power in the United States. In coal-fired power plants, bituminous coal, subbituminous coal, or lignite is burned. The heat produced by the combustion of the coal is used to convert water into high-pressure steam, which drives a turbine, which produces electricity.
Explanation:
Explanation:
-lipid
Lipids function as energy storage and chemical messengers, these include fats, saturated and unsaturated fatty acids with double bonds and steroids and waxes. However, lipids are comprised of fatty acids and glycerol; they do not contain a fixed set of monomers, and unlike the other biological macromolecules, they are not polymers.
The arrangement of hydrophobic heads and hydrophobic fatty acid tails can give these non-polar macromolecules hydrophilic and hydrophobic properties. Basic makeup: C, H, O; non polar- a triple condensation reaction produces the molecules from a triple hydroxyl (OH) alcohol bonded to three long-chain carboxylic acids.
