Yogurt and cheese are produced by involving lactic acid fermentation. Lactic acid fermentation is a process in which lactose, a sugar present in milk, is converted into lactic acid by bacteria. This process gives yogurt its tangy taste and thick texture. Similarly, in cheese production, lactic acid fermentation is important for curdling the milk and developing the characteristic flavors and textures of different types of cheese. Therefore, the correct answer is B, c.

The correct answer is B. The RDA's for Indian women are based on a reference woman who has a body weight of 55 kg and a height of 1.61 m. This means that the recommended dietary allowances for nutrients and energy intake are determined based on the needs of a woman with these specific body weight and height measurements.

HDL, or high-density lipoprotein, is synthesized and secreted from the liver. The liver plays a crucial role in lipid metabolism, including the production and secretion of HDL particles. HDL is responsible for transporting cholesterol from peripheral tissues back to the liver, where it can be metabolized and excreted. Therefore, the correct answer is B, the liver.

Stewing involves cooking food in liquid, making it a moist-heat cooking method. Dry-heat methods, on the other hand, use air or fat to transfer heat to the food, resulting in browning and crisping.

The correct answer is (B) Both (A) and (R) are correct.
The assertion states that the height or length of children below the age of two years should be measured with an infantometer. This is correct because infants at this age are unable to stand properly, and an infantometer is specifically designed to measure their height or length accurately. Therefore, both the assertion and the reason are correct.

GOTS stands for Global Organic Textile Standards. This is a certification system that ensures the organic status of textiles, from the harvesting of the raw materials to the manufacturing process. GOTS sets strict criteria for both environmental and social responsibility in the production of textiles, including the use of organic fibers, the exclusion of harmful chemicals, and fair labor practices. The certification allows consumers to make informed choices when purchasing organic textiles, promoting sustainability and ethical practices in the industry.

The selection of needle is governed by the type of fabric. Different fabrics have different characteristics and require different types of needles to ensure proper stitching. For example, a heavy fabric may require a thicker needle to penetrate through the layers, while a delicate fabric may require a finer needle to avoid damaging the fibers. Therefore, the type of fabric is an important factor to consider when selecting the appropriate needle for a sewing project.

The degree of polymerization for polyester ranges between 115 and 140. This means that the polyester molecules consist of 115 to 140 repeating units of monomers.

The design repeat refers to the distance between the starting point of a pattern and the next occurrence of that same point. A drop repeat is when the pattern is repeated vertically, a mirror repeat is when the pattern is repeated and flipped horizontally, and a satin repeat is when the pattern is repeated diagonally. However, a rotary repeat does not exist in design terminology, making option C the correct answer.

The given answer, 2,3,5, is correct because the cool colors listed are bluish green (2), blue (3), and green (5). These colors are considered cool because they are associated with calmness, tranquility, and a sense of relaxation. Reddish orange (2) and yellow orange (4) are warm colors and do not fall into the category of cool colors.
