Approximately 4.6 billion years ago, the solar system was a cloud of dust and gas known as a solar nebula. Gravity collapsed the material in on itself as it began to spin, forming the sun in the center of the nebula.
With the rise of the sun, the remaining material began to clump together. Small particles drew together, bound by the force of gravity, into larger particles. The solar wind swept away lighter elements, such as hydrogen and helium, from the closer regions, leaving only heavy, rocky materials to create terrestrial worlds. But farther away, the solar winds had less impact on lighter elements, allowing them to coalesce into gas giants. In this way, asteroids, comets, planets and moons were created.
Answer:
The feasibility and profitability of game ranching have been amply demonstrated by a number of studies. The rationale behind advocating game ranching in Africa is that conditions in many parts of' the continent, whether resulting from inadequate rainfall or presence of certain disease organisms' are not appropriate for production of exotic cattle and other domestic stocks. Indigenous wild animal species on the other hand have evolved in the African ecosystem and are better adapted to the prevailing conditions and should therefore be more productive.
Game ranching is currently most developed in southern Africa (particularly South Africa Namibia and Zimbabwe), although a private game ranch, the Galana Ranch, was established in Kenya in the 1970s (King and Heath, 1975; Thresher, 1980). The ranch initially focused on three species: the fringe eared oryx, Oryx beisa callotis, the African buffalo and the eland. Reported advantages of the eland over the Boran cattle included much lower water requirement, faster breeding and growth, earlier maturity and ability to put on weight in grazing conditions under which the Boran cattle began to lose weight and approximately 14 % higher dressing out weight. In addition to these biological and physiological advantages a cost-benefit analysis of maintaining a breeding herd of 11,000 oryx and 5000 Boran on the ranch showed clearly that the financial returns on the oryx was far superior to that of cattle (Thresher, 1980).

Answer:
The correct answer is -
1. Blending - C
2. Straining - D
3. Detergents - B
4. Meat tenderizer (protein enzymes) - E
5. Alcohol - A
Explanation:
To extract protein from various parts of the organisms there is a scientific process that helps in successfully extract it. Organisms such as plants have a rigid cell wall that is required to be broken in order to follow the scientific process of extracting DNA and protein.
Blending use to break the cell wall of the plants such as pea cells. After breaking the cell wall one needs to dissolve the cell membrane made up of lipids with the help of soap or detergents. After the dissolving cell membrane, there is a chance to DNA gets damaged by various chemicals, therefore, alcohol is used to allow DNA to form clumps or precipitate.
Straining is used to separate the cell organelle, dissolved cell membrane from DNA and protein. Papain is a meat tenderizer and a protein enzyme that cuts or breaks the protein.
