Question: Context: Ant & Dec are an English comedy TV presenting duo, consisting of Anthony McPartlin OBE and Declan Donnelly OBE , from Newcastle upon Tyne, England. Formed after their meeting as actors on CBBC's drama, Byker Grove, the duo have led successful careers as television presenters, with hosting credits including SMTV Live, CD:UK, Friends Like These, Pop Idol, Ant & Dec's Saturday Night Takeaway, I'm a Celebrity...Get Me Out of Here!, PokerFace, Push the Button, Britain's Got Talent, Red or Black?, and Text Santa. Due to a difference in height - Ant being the taller at 5ft 8in , and Dec being two inches shorter at 5ft 6in - the pair identify themselves in the media by adopting the use of the 180-degree rule, with the exception of some early publicity shots. In addition to presenting, the duo are accomplished actors - both had leading roles in the 2006 film Alien Autopsy - operate as television producers - they own their own production company, Mitre Television - have presented the annual Brit Awards in 2001, 2015 and 2016, and are former pop musicians who operated under the aliases of their characters from Byker Grove. In a 2004 poll for the BBC, Ant & Dec were named the eighteenth most influential people in British culture. 
 Question: Who is the "Dec" in "Ant & Dec"?

Answer: declan donnelly obe


Question: Context: During active transport, molecules move from an area of low concentration to an area of high concentration. This is the opposite of diffusion, and these molecules are said to flow against their concentration gradient. Active transport is called "active" because this type of transport requires energy to move molecules. ATP is the most common source of energy for active transport. As molecules are moving against their concentration gradients, active transport cannot occur without assistance. A carrier protein is always required in this process. Like facilitated diffusion, a protein in the membrane carries the molecules across the membrane, except this protein moves the molecules from a low concentration to a high concentration. These proteins are often called "pumps" because they use energy to pump the molecules across the membrane. There are many cells in your body that use pumps to move molecules. For example, your nerve cells (neurons) would not send messages to your brain unless you had protein pumps moving molecules by active transport. The sodium-potassium pump ( Figure 1.1) is an example of an active transport pump. The sodium-potassium pump uses ATP to move three sodium (Na+ ) ions and two potassium (K+ ) ions to where they are already highly concentrated. Sodium ions move out of the cell, and potassium ions move into the cell. How do these ions then return to their original positions? As the ions now can flow down their concentration gradients, facilitated diffusion returns the ions to their original positions either inside or outside the cell. 
 Question: which statement is true concerning active transport?

Answer: during active transport, molecules move from an area of low concentration to


Question: Context: Haploinsufficiency of the NSD1 gene due to 5q35 microdeletions or intragenic mutations is the major cause of Sotos syndrome characterized by generalized overgrowth, large hands and feet with advanced bone age, craniofacial dysmorphic features, learning disability, and possible susceptibility to tumors. Here, we report on a 14-month-old boy with a reverse phenotype of Sotos syndrome due to the reciprocal duplication of the 5q35.3 region, including the NSD1 gene, detected by array CGH. The phenotype includes delayed bone age, microcephaly, seizures, and failure to thrive. Our case suggests that the gene dosage effect of the NSD1 gene is the likely cause for the reversed phenotype of Sotos syndrome in this patient. 
 Question: Which gene is responsible for the development of Sotos syndrome?

Answer:
nsd1 gene
