Iodine test on food implies testing for

Antwoorddetails

Iodine test on food is used to test for the presence of carbohydrates. Carbohydrates are a type of macronutrient found in foods like bread, rice, and pasta. Iodine, when mixed with starch (a type of carbohydrate), reacts by turning from brown to blue-black in color. This is because iodine molecules slip into the coils of starch molecules, forming a complex that reflects light differently and appears blue-black to the human eye. Proteins, fats, and vitamins do not react with iodine in the same way as carbohydrates, and therefore the iodine test is not used to test for their presence. For example, fats do not contain the type of chemical bonds that iodine can react with, so there is no color change when iodine is added to a sample of fat. Similarly, vitamins do not react with iodine in a way that produces a color change. In summary, the iodine test is used specifically to test for carbohydrates in food by looking for a color change from brown to blue-black.

A suitable finishing for materials that do not fray is

Antwoorddetails

If a material does not fray, it means that it does not unravel or develop loose threads along its cut edges. For such materials, a suitable finishing technique is needed to prevent the cut edges from becoming worn or damaged. One common finishing technique is called pinking. It involves cutting the edges of the material with pinking shears, which are scissors with serrated blades that create a zigzag pattern along the edge. This pattern helps to prevent fraying and adds a decorative touch to the finished product. Therefore, the correct answer is "pinking."

The raising agent used in the preparation of omelette is

Antwoorddetails

The raising agent used in the preparation of omelette is air. When beaten eggs are cooked in a pan, air gets trapped within the mixture and creates pockets of air, which cause the omelette to rise and become fluffy. Therefore, no additional raising agent like yeast, baking powder, or baking soda is needed to make an omelette.

Rancidity is a type of spoilage associated with

Antwoorddetails

Rancidity is a type of spoilage associated with butter. Butter is a dairy product made from milk or cream, and it contains fats that can become rancid over time. Rancidity is a process that occurs when the fats in butter are exposed to oxygen, causing them to break down and produce unpleasant flavors and odors. Frozen beef and chicken can also spoil over time, but this type of spoilage is typically associated with freezer burn, which occurs when the food becomes dehydrated and develops a dry, tough texture. Milk can spoil as well, but this type of spoilage is typically characterized by sourness, rather than rancidity. To prevent rancidity in butter, it is important to store it properly in an airtight container in a cool, dark place. It is also important to use butter within its recommended shelf life and to check for signs of spoilage, such as an off odor or flavor, before consuming it.

Antwoorddetails

The cleaning agent recommended for the prevention of blockage in a sink is a nylon sponge. When we use our sinks, small bits of food, grease, and other debris can build up and eventually create a blockage. To prevent this, we need a cleaning agent that can effectively scrub away the debris without damaging the sink. An iron sponge and steel wool are too abrasive and can scratch the sink's surface, making it more difficult to clean in the future. Fresh leaves, on the other hand, will not be able to effectively scrub away the debris and may even contribute to the blockage if they end up in the sink. A nylon sponge, however, is soft enough to prevent damage to the sink while still being tough enough to scrub away any debris. Additionally, it can be used with soap or cleaning solution to further aid in the cleaning process. Overall, a nylon sponge is the best option for preventing blockage in a sink.

Injuries on the skin without any cut but swollen and painful is a

Antwoorddetails

When an injury occurs on the skin without any cut, but the affected area becomes swollen and painful, it is typically a bruise. A bruise, also known as a contusion, happens when small blood vessels underneath the skin are damaged or broken due to an impact or injury. Blood leaks out of the damaged vessels and pools in the surrounding tissues, causing a discoloration that ranges from black and blue to purple and yellow as the body reabsorbs the blood. In contrast, a scald is a type of burn caused by hot liquids or steam, while a burn is an injury caused by heat, chemicals, electricity, or radiation. A tear, on the other hand, refers to a cut or a rip in the skin or other tissues.

Antwoorddetails

The relationship that exists between siblings excludes marriage. Siblings are brothers and sisters who share a bond that is different from any other relationship. They may grow up together, share experiences, and have a lifelong connection. Sibling relationships can be characterized by companionship, love, and support, as well as occasional conflict and rivalry. Siblings can provide each other with a sense of security and understanding that comes from a shared history and a deep emotional connection. While siblings may not always agree with each other, they often have a deep respect for each other's views and opinions. However, the relationship between siblings is not a romantic one, and therefore excludes marriage. Siblings are not allowed to marry each other because it is considered incestuous and against the laws of most countries.

Antwoorddetails

The BCG vaccine is a vaccine that is administered to children to help build immunity against tuberculosis. Tuberculosis is a bacterial infection that mainly affects the lungs but can also affect other parts of the body. It is a serious infectious disease that can be spread through the air when an infected person coughs or sneezes. The BCG vaccine contains a weakened strain of the bacteria that causes tuberculosis, which stimulates the body's immune system to produce a response that helps to protect against the disease. While the BCG vaccine may offer some protection against other related bacteria, it is mainly used to prevent tuberculosis. It is important to note that the BCG vaccine is not 100% effective, and other measures such as good hygiene practices are also necessary to prevent the spread of tuberculosis.

A stitch used in transferring the markings on the pattern to the fabric is

Antwoorddetails

The stitch used in transferring markings on a pattern to fabric is called tailor tacking. When making a garment or other sewing project, it's often necessary to transfer markings from the pattern onto the fabric. Tailor tacking is a type of stitch that is used for this purpose. It involves creating temporary markings on the fabric by sewing through both layers of the pattern and fabric with a contrasting color of thread. This creates a visible line of stitches on the fabric that can be used as a guide for cutting and sewing. Tailor tacking is often used for transferring markings such as darts, pleats, or other design elements from the pattern to the fabric. Once the markings have been transferred, the tailor tacking stitches can be removed by gently pulling on the threads. Basting, over sewing, and herringbone are other types of stitches used in sewing, but they are not typically used for transferring markings from a pattern to fabric.

HIV/AIDS CANNOT be contacted through

Antwoorddetails

HIV/AIDS cannot be contacted through kissing. Kissing involves only saliva, which does not contain enough concentration of the virus to transmit HIV. However, HIV can be transmitted through blood transfusion, unsterilized injection, and sharing of needles. Manicure and pedicure, although involving sharp objects, have very low chances of transmitting HIV, especially when proper sanitation and hygiene practices are followed. It is important to note that HIV/AIDS is primarily transmitted through sexual contact, sharing of needles, and from mother to child during pregnancy, childbirth, or breastfeeding.

Starch is used in laundry to stiffen

Antwoorddetails

Starch is used in laundry to stiffen cotton and linen materials. When starch is applied to these fabrics and then ironed, it creates a crisp and polished look that is desired for some clothing items such as dress shirts, tablecloths, and napkins. Starch works by coating the fibers of the fabric, which creates a smooth surface that is more resistant to wrinkles and creases. Additionally, starch can help to protect the fabric from dirt and stains, as well as make it easier to iron. While starch can be used on other fabrics, such as wool and silk, it is more commonly used on cotton and linen due to their absorbent properties and ability to hold starch well.

Antwoorddetails

The correct option is "change in voice and appearance." During adolescence, boys experience significant physical and hormonal changes, leading to growth spurts, changes in body shape, and changes in voice as their vocal cords lengthen and thicken. These changes are associated with the increased production of testosterone, the primary male hormone responsible for the development of male characteristics. Adolescents may also experience emotional changes, such as mood swings and increased risk-taking behavior, as the brain continues to develop during this stage. However, the production of oestrogen and progesterone is a characteristic of females, not males.

Household pests can be controlled through the use of

Antwoorddetails

Household pests such as cockroaches, ants, termites, bed bugs, and rodents can be controlled through the use of insecticides. Insecticides are chemical substances that are formulated to kill or control pests. They come in various forms such as sprays, baits, powders, and granules, and they are designed to target specific pests. Kerosene and alcohols are not effective for controlling household pests, as they do not contain the necessary chemicals to kill or control pests. In fact, using kerosene or alcohol to try to control pests can be dangerous and may even cause a fire. "Pestifume" is not a commonly used term, and it is not clear what it refers to. If it is a misspelling of "pest fumigation," then it is a method of pest control that involves using fumigants to kill pests. However, fumigation is typically a more expensive and complex method of pest control that is usually only used in extreme cases, and it requires professional training and equipment.

A combination of fat and flour cooked together is asauce

Antwoorddetails

A combination of fat and flour cooked together is called a roux, which is a common base for making sauces. To make a roux, equal parts of fat and flour are heated and stirred together until they are well combined and the flour is cooked, which gives the roux a nutty flavor and removes the raw taste of the flour. The type of fat used can vary, but butter and oil are commonly used. The roux can then be used as a base for a variety of sauces by adding liquid, such as milk or broth, and other flavorings, such as herbs or spices. The resulting sauce can be thickened or thinned to achieve the desired consistency. Roux-based sauces are commonly used in cooking, particularly in French cuisine. Examples of sauces made with roux include béchamel sauce, which is a white sauce made with milk, and velouté sauce, which is a light-colored sauce made with chicken, fish, or veal broth. In summary, a combination of fat and flour cooked together is called a roux, and it is a common base for making sauces.
