Here is a question about this article: Some viruses store their entire genomes in the form of RNA, and contain no DNA at all. Because they use RNA to store genes, their cellular hosts may synthesize their proteins as soon as they are infected and without the delay in waiting for transcription. On the other hand, RNA retroviruses, such as HIV, require the reverse transcription of their genome from RNA into DNA before their proteins can be synthesized. RNA-mediated epigenetic inheritance has also been observed in plants and very rarely in animals.
What is the answer to this question: Besides viruses, where has RNA-mediated epigenetic inheritance been observed?
****
So... in plants and very rarely in animals


Here is a question about this article: The Royal Australian Navy is in the process of procuring two Canberra-class LHD's, the first of which was commissioned in November 2015, while the second is expected to enter service in 2016. The ships will be the largest in Australian naval history. Their primary roles are to embark, transport and deploy an embarked force and to carry out or support humanitarian assistance missions. The LHD is capable of launching multiple helicopters at one time while maintaining an amphibious capability of 1,000 troops and their supporting vehicles (tanks, armoured personnel carriers etc.). The Australian Defence Minister has publicly raised the possibility of procuring F-35B STOVL aircraft for the carrier, stating that it "has been on the table since day one and stating the LHD's are "STOVL capable".
What is the answer to this question: How many helicopters is the LHD capable of launching?
****
So... multiple helicopters at one time


Here is a question about this article: On runways, green lights indicate the beginning of the runway for landing, while red lights indicate the end of the runway. Runway edge lighting consists of white lights spaced out on both sides of the runway, indicating the edge. Some airports have more complicated lighting on the runways including lights that run down the centerline of the runway and lights that help indicate the approach (an approach lighting system, or ALS). Low-traffic airports may use pilot controlled lighting to save electricity and staffing costs.
What is the answer to this question: What may low-traffic airports use to save electricity and staffing costs?
****
So...
pilot controlled lighting
