Does technology have a positive or a negative effect on personal safety?
Technology is ever-evolving. It does more to promote personal safety than it does to compromise it. A sword will protect us only if used safely. Using technology requires us to take certain precautions for it to act in our favor. Whether it is at home, leisure, or workplace, technology serves to enhance our safety. High tech door locks and security systems, further secured by remote functions and alerts through cellphones, protect our homes and cars (Mentalfloss. n.d. para 8-10). Secure and improved electronic record systems protect them from theft and viruses, making them a better option than physical records (Brown, 2017, para 6). Information stored in electronic systems is well secured by data encryption. The use of biometrics to lock devices makes hacking nearly impossible. The True Key app enables the use of our cellphone as a ‘key’ to lock our laptop or tablet for increased security (Mentalfloss. n.d. para 2-6). Online banking through these devices, coupled with limiting the access to a single device, makes infiltration into the account nearly impossible. One can locate a lost device through apps like Prey and LoJack and even lock its hard drive remotely through a second device, like a cellphone. The feature of wireless charging of phones protects its data by eliminating the need to plug it into wire (Mentalfloss. n.d. para 3& 11). The use of technology at the workplace improves worker safety. Training software help to create awareness regarding safety, thus reducing risky behaviors (Melo, 2018, para5). Technologically improved PPEs like high-tech lenses, flame-resistant clothing, and cut-resistant gloves provide better protection. Wearable microchips monitor the vital signs of workers to send alerts when in unsafe environments. They also send alerts to team members in the vicinity of an injured worker. Walkie-talkies and handheld phones allow the passing of information about hazards to team members (Brown, 2017, para5 & 8). Fast communication of risks by workers at remote locations and timely response are all made possible by technological support like voice and video calls, GPS, biometrics tracking, and early detection of chemical exposure. DataScope is a useful app that enables communication between remote workers and base teams and provides automated alerts for employee safety (Melo, 2018, para4-7). Risks involved in the use of any technological system are minimal if used after gaining its apt knowledge understanding. Thanks for reading.References Brown, D. February 6, 2017.

What are the merits and demerits of free healthcare?
The World Health Organization lists access to affordable health services of decent quality as one of the Social Determinants of Health (WHO, n.d., para 2). The basic aim of free healthcare is the provision of healthcare to all, without any financial or demographic discrimination, so that health is protected and maintained, and illness is alleviated (Justice Laws Website,1985, “Interpretation”). All are uniformly entitled to quality healthcare, irrespective of financial, social, or existing health status, without any disparity in services (Justice Laws Website,1985, “Program Criteria”). This prevents any delay in medical care for want of payment in cases of the poor, mentally disoriented, elderly, accident cases, and the like, thus ensuring a healthier society. Treatments are sought early on in the illness, thus reducing the extent of ailment and the expenditure on treatment. Uniform and free healthcare were greatly responsible for Canada getting a relatively early grip on COVID. There are some drawbacks to the system. Patients that need early attention may not receive it, especially those who cannot advocate for themselves like the mentally ill. What services are deemed essential is entirely for the system to decide. The patient has no say. It runs low on finances due to its dependence on government funding. Hence there is a paucity of resources, technology, training, and research (Concordia University Chicago, n.d., “Financial Issues in Human Services”). Often, it allows the system to become lax. It also makes the administration to be overly restrictive in recruiting new healthcare professionals and in building new hospitals, such that there is always a need for more. The government avoids delving into new projects due to excessive accountability. A new hospital with the risk of losses might spell political peril for the government because of the excessive public eye. Thanks for reading. References Concordia University Chicago, n.d.

What are the similarities and differences between DNA and RNA?
Deoxyribonucleic Acid (DNA) and Ribonucleic Acid (RNA) are complex compounds called nucleic acids. They are to living beings what bricks are to buildings. They are the basic units that join together to form living organisms and continue to do so through maintenance, repair, and replication. DNA determines heredity. It expresses itself by acting as a template for protein synthesis through the use of RNA. Both, DNA and RNA, are complex compounds formed by the linking of monomeric nucleotides into linear chains. Nucleotides are complex compounds made by the joining of a pentose sugar and a nitrogenous base to a phosphate backbone (Albert, n.d., para1). The sugar in DNA is deoxyribose, while that in RNA is ribose. Ribose is actually deoxyribose with an extra hydroxyl group (OH−) attached to it. The nitrogenous bases in both are of four types. Adenine, guanine, and cytosine are common to both. The fourth base in RNA is uracil and in DNA is thymine. Thymine is uracil with a methyl group attached to it (Slizewska, n.d., para 4,5). Both, DNA and RNA, are synthesized using DNA as a template (Albert, n.d., para6). DNA is found in eukaryotes while RNA is found in both, prokaryotes and eukaryotes. DNA carries genetic information to transmit traits. RNA acts as genetic material in only retroviruses (Genetic Education. n.d., para 3,4). DNA carries genetic information through the generations of species and needs to be protected from mutations. It is prone to destruction and damage. It is protected by its double-stranded structure. RNA is more resilient. It can move between the nucleus and the cytoplasm, enabling it to function as a messenger for DNA (Albert, n.d., para7,8). References Albert. n.d.
