NTA UGC NET-JRF EXAM, December 2023 Paper II (HOME SCIENCE)

The correct sequence for the stages of Kalamkari is:
(A) Fabric is immersed in a solution of cow dung
(E) The cloth is treated in myrobalon solution
(B) The iron acetate solution is filled in for solid space or as an outline
(D) All the portions that are not to be blued are covered with wax and after wax is removed by boiling the cloth in water
(C) Mordanting by applying alum solution
This sequence outlines the traditional steps involved in the Kalamkari process, which includes treating the fabric, applying various solutions for coloration and mordanting, and waxing to preserve certain areas from dye.

Strategies like trying to remake your spouse, using coercive power, and insisting solely on your rights do not lead to marital happiness. These approaches undermine trust, respect, and mutual understanding, which are essential for a healthy and fulfilling marriage. Instead, open communication and respectful consideration for each other promote marital happiness by fostering trust, empathy, and partnership.

Kasuti embroidery, a traditional form of Indian embroidery from Karnataka. The stitches used in kasuti embroidery are:-
Gavanti:- Gavanti stitch is a basic straight stitch used in Kasuti embroidery. It is often used to create outlines and basic geometric patterns in the design.
Murgi:- Murgi stitch, involves creating small straight stitches in a diagonal pattern. This stitch is often used to fill in spaces within the design and add texture to the overall pattern. Methi:- Methi stitch, also known as the zigzag stitch, is another common stitch used in Kasuti embroidery. It is used to create zigzag or crisscross patterns, adding detail and texture to the design. Whereas murri and taipachi are type of stitch commonly used in Chikankari embroidery, particularly in Lucknow, India.

Type I error is a statistical concept related to hypothesis testing.
Rejecting the null hypothesis when it is true: In hypothesis testing, the null hypothesis (denoted as H0) represents the default assumption or the hypothesis of no effect, no difference, or no relationship. Type I error occurs when the null hypothesis is true, but the statistical test incorrectly leads to its rejection. In other words, it’s a false positive result in reality, there isn’t one.
Type I errors are important to consider because they indicate the risk of concluding that an effect exists when it doesn’t. The significance level, denoted as alpha (α), represents the probability of committing a Type I error in hypothesis testing. It’s typically set before conducting the statistical test and serves as the threshold for rejecting the null hypothesis. Understanding and minimizing Type I errors are crucial in statistical analysis, especially in fields where false positives can lead to incorrect conclusions or decisions

Concurrent validity refers to the extent to which the results of a test correlate with those of a similar test administered at the same time. It’s about how well the test scores match up with scores from other tests or measures administered simultaneously. While concurrent validity is indeed important, the statement provided seems to focus more on the relationship between the test and established criteria, which aligns better with criterion-related validity.

Radio is primarily a medium for mass communication because it has the capability to reach a large audience simultaneously. It broadcasts information, news, entertainment, and other content to a wide population regardless of geographical location.
Unlike interpersonal communication, which involves direct interaction between individuals, radio broadcasts are intended for a broad audience and can influence public opinion, disseminate information on a large scale, and shape societal discourse. Therefore, radio is most commonly associated with mass communication due to its ability to reach and impact a significant number of people at once.

The new logo introduced by FSSAI in September 2021 for vegan food is a green-colored ‘V’ inscribed in the middle of a square box, with a small plant on top of it and “vegan” written at the bottom.

Farm and Home Visit is not typically considered a method of group contact. Instead, it involves individualized or family-level interactions rather than group interactions. The other options listed – field trip, conference, and demonstration – are more commonly associated with group contact methods where multiple individuals participate in activities or discussions together.

The scenario described, where a parent puts their arm around the child’s shoulder in a comforting manner and engages in constructive dialogue about handling situations better next time, is characteristic of the authoritative parenting style. Authoritative parenting style emphasizes warmth, support, and clear communication combined with reasonable boundaries and expectations. It encourages independence, self-regulation, and open communication between parent and child while also providing guidance and support.
This approach fosters a positive parent-child relationship based on mutual respect and understanding, promoting the child’s social and emotional development in a supportive environment.

Counter-regulatory hormones work in opposition to insulin, primarily to regulate blood glucose levels. Glucagon, cortisol and growth hormone are counter regulatory hormone :-
1. Glucagon: Glucagon is released by the pancreas and works to increase blood glucose levels by stimulating the liver to break down glycogen into glucose, which is then released into the bloodstream.
2. Cortisol:- Cortisol, often referred to as the stress hormone, is released by the adrenal glands. It increases blood glucose levels by promoting gluconeogenesis (the production of glucose from non-carbohydrate sources) in the liver.
3. Growth hormone:- Growth hormone, produced by the pituitary gland, also contributes to increasing blood glucose levels by reducing glucose uptake in tissues and promoting gluconeogenesis.
Therefore, the correct answer is (4) Antidiuretic hormone. It is not a counter-regulatory hormone of insulin.
Antidiuretic hormone (ADH): ADH, also known as vasopressin, is primarily involved in regulating water balance and blood pressure by controlling the amount of water reabsorbed by the kidneys. It does not directly influence blood glucose levels or act as a counterregulatory hormone to insulin.
