PTC sensitivity is often used as an example of a simple Mendelian trait with dominant inheritance. However, tasters varygreatly in their sensitivity to PTC. And while the PTC gene has about 85% of the total influence over whether someone is ataster or a non-taster, there are many other things that affect PTC tasting ability. Having a dry mouth may make it moredifficult to taste PTC. What you ate or drank before sampling PTC paper may also affect your tasting ability. And anindividual's sensitivity may change over time. Some people may find that they can taste PTC on some days, but not on others.

"The brown paper bag test" is a term in African-American oral history used to describe a racist discriminatory practice within the African-American community in the 20th century, in which an individual's skin tone is compared to the color of a brown paper bag. The test was used to determine what privileges an individual could have; only those with a skin color that matched or was lighter than a brown paper bag were allowed admission or membership privileges. The test was believed by many to be used in the 20th century by many African-American social institutions such as sororities, fraternities, and social clubs.[1]

The term is also used in reference to larger issues of class and social stratification and colorism within the African-American population. People were barred from having access to several public spaces and resources because of their darker complexion.[2]The test was used at the entrance to social functions wherein a brown paper bag was stuck at the door and anyone who was darker than the bag was denied entry.

Privilege has long been associated with skin tone in the African-American community, dating back to the era of slavery. Mixed-race children of European American fathers were sometimes given privileges ranging from more desirable work, apprenticeships or formal education, to allocation of property or even freedom from enslavement. African Americans "contributed to colorism because they have benefited from the privilege of having a skin color closer to that of European Americans and have embraced the notion that privilege comes with having light skin in America".[3] Lighter-skinned people were afforded certain social and economic advantages over darker-skinned people, even while suffering discrimination. According to Gordon, "light-skinned blacks formed exclusive clubs" after African slavery was abolished in the United States.[4] Some clubs were called "Blue Vein Societies", suggesting that if an individual's skin was light enough to show the blue cast of veins, they had more European ancestry (and, therefore, higher social standing).[4] Such discrimination was resented by African Americans with darker complexions. According to Henry Louis Gates Jr., in his book The Future of the Race (1996), the practice of the brown paper bag test may have originated in New Orleans, Louisiana, where there was a substantial third class of free people of color dating from the French colonial era.[5] The test was related to ideas of beauty, in which some people believed that lighter skin and more European features, in general, were more attractive.

From 1900 until about 1950, "paper bag parties" are said to have taken place in neighborhoods of major American cities with a high concentration of African Americans. Many churches, fraternities, and nightclubs used the "brown paper bag" principle as a test for entrance. People at these organizations would take a brown paper bag and hold it against a person's skin. If a person was lighter than the bag, they were admitted.[6]

Rapid, sensitive, on-site detection of bacteria without a need for sophisticated equipment or skilled personnel is extremely important in clinical settings and rapid response scenarios, as well as in resource-limited settings. Here, we report a novel approach for selective and ultra-sensitive multiplexed detection of Escherichia coli (non-pathogenic or pathogenic) using a lab-on-paper test strip (bioactive paper) based on intracellular enzyme (-galactosidase (B-GAL) or -glucuronidase (GUS)) activity. The test strip is composed of a paper support (0.5 8 cm), onto which either 5-bromo-4-chloro-3-indolyl--D: -glucuronide sodium salt (XG), chlorophenol red -galactopyranoside (CPRG) or both and FeCl(3) were entrapped using sol-gel-derived silica inks in different zones via an ink-jet printing technique. The sample was lysed and assayed via lateral flow through the FeCl(3) zone to the substrate area to initiate rapid enzyme hydrolysis of the substrate, causing a change from colorless-to-blue (XG hydrolyzed by GUS, indication of nonpathogenic E. coli) and/or yellow to red-magenta (CPRG hydrolyzed by B-GAL, indication of total coliforms). Using immunomagnetic nanoparticles for selective preconcentration, the limit of detection was ~5 colony-forming units (cfu) per milliliter for E. coli O157:H7 and ~20 cfu/mL for E. coli BL21, within 30 min without cell culturing. Thus, these paper test strips could be suitable for detection of viable total coliforms and pathogens in bathing water samples. Moreover, inclusion of a culturing step allows detection of less than 1 cfu in 100 mL within 8 h, making the paper tests strips relevant for detection of multiple pathogens and total coliform bacteria in beverage and food samples.

Biology questions held the highest weightage in the NEET 2022 paper as the maximum marks that can be scored in Biology is 360. 90 questions out of a total of 180 appear in the Biology section. More than 80% of this section on average sees questions either directly or indirectly appearing from NCERT content. As a result, students usually score well in this section.

Assign scores or grades on the overall quality of the written response as compared to an ideal answer. Or, compare the overall quality of a response to other student responses by sorting the papers into three stacks:

The TSA and BMAT tests will be taken by candidates on 18 October. Any questions regarding either of these tests should be directed to Cambridge Assessment Admissions Testing (CAAT). CAAT recently announced its decision to withdraw from delivering its admissions testing services over the next two years. In 2023, they will deliver paper-based TSA and BMAT tests for the final time but will not be delivering Oxford's own tests.

Further information on arrangements for Oxford's admissions tests for 2024-entry is available on individual test pages (see menu below). This includes extensive guidance on test preparation, access to past papers and other practice materials and resources. Evidence suggests that people who have researched and practised their test do better. We strongly recommend that all candidates taking one of Oxford's own tests have a go at the online practice test (in most cases the 2022 past paper) available on their test page. This will allow you not only to familiarise yourself with the structure and content of your test but also to learn to navigate the digital test platform and practise using the tools available to support you. On your test day, you will then be able to focus fully on the content of your answers.

Students are required to participate in the ILEARN Biology End-of-Course Assessment (ECA) upon completion of the high school biology course to fulfill a federal participation requirement. The ILEARN U.S. Government ECA is available per state legislation as an optional assessment for students upon completion of the high school U.S. Government course. A student may only have one test attempt for any given ILEARN assessment. There are no retest opportunities available for ILEARN assessments.

This section includes recent GCSE Biology past papers from AQA, Edexcel, OCR (Gateway and Twenty First Century), WJEC, CCEA and the CIE IGCSE. This section also includes SQA National 5 biology past papers. If you are not sure which exam board you are studying ask your teacher. Practicing past papers is one of the best ways to prepare for an exam. You can download each of the exam board's papers by clicking the links below.

Some of the 2022 and 2023 past papers are labelled 'modified'. This means SQA made changes to the question paper in response to the disruption caused by the Covid-19 pandemic, as part of our modifications to assessment in National Courses. For example, a modified past paper may be shorter, have fewer marks or contain fewer topics than past papers from previous years.

Specimen question papers are available for National 5, Higher and Advanced Higher qualifications. These show what a question paper looks like - how it is structured and the types of questions it contains. They also include marking instructions.
