Answer: False
Explanation: The density of the liquid will always be the same, no matter how much of the liquid you have.
For example, the density of the water in a pool is the same density as the water in a small cup.
Saponification is the hydrolysis of fats or oils under basic conditions to afford glycerol and the salt of the corresponding fatty acid. ... It is important to the industrial user to know the amount of free fatty acid present, since this determines in large measure the refining loss.
Answer:
There are now two oxygen atoms on the left and four on the right (in one N2O and three H2O's), so we balance the oxygen atoms by placing a 2 in front of the O2.
Answer:
A) It is a practical source of energy on Earth.
Explanation:
The reaction shown is a nuclear fusion reaction. Nuclear fusion refers to the combination of two light nuclei to produce a heavier nuclei with a release of tremendous amount of energy. The energy released in a fusion reaction is so great and it is often difficult to achieve fusion reactions in a controlled nuclear reactor.
Fusion reactions just like the one shown is the source of energy on earth. The energy reaching the earth is obtained by fusion reactions in outer space.
Answer:
The food we humans eat every day throughout our lives comes from agricultural biodiversity. Biodiversity is the basis of agriculture and our food systems. It has enabled farming systems to evolve since the origin of agriculture about 10,000 years ago. Our civilization evolved when human beings started domesticating plants and animals.
Agricultural biodiversity includes all components of biological diversity of relevance to food and agriculture. It includes plants’ genetic resources: crops, wild plants harvested and managed for food, trees on farms, pastures and rangeland species, medicinal plants and ornamental plants of aesthetic value. Animal genetic resources include domesticated animals, wild animals hunted for food, wild and farmed fish and other aquatic organisms, insect pollinators and microbial and fungal genetic resources.
Agricultural biodiversity provides humans with food, raw materials for goods such as: cotton and wool for clothing; wood for shelter and fuel; plants and roots for medicines; and materials for biofuels. Agricultural biodiversity also performs ecosystem services such as soil and water conservation, maintenance of soil fertility, conservation of biota and pollination of plants, all of which are essential for food production and for human survival. In addition, genetic diversity of agricultural biodiversity provides species with the ability to adapt to changing environments and to evolve by increasing their adaptation to frost, high temperature, drought and waterlogging as well as their resistances to diseases, insects and parasites.
The importance of agricultural biodiversity encompasses socio-cultural, economic and environmental elements. All domesticated crops and animals result from management of biodiversity, which is constantly responding to new challenges to maintain and increase productivity under constantly varying conditions and population pressures. Agricultural biodiversity is essential to satisfy basic human needs for food and livelihood security
