describe the day when you wake up on the first day of complete lock down due to covid-19. State what you saw and what were were your feelings English -1st |
|
Answer» Answer: With my end of YEAR assessments finally completed and out of the way, I thought I’d look back at how student life was affected by the Covid-19 pandemic and subsequent lockdown. Alarm clock on stack of books Just before lockdown, I decided to leave London and move in with my family back at my home in Bristol. It was a hastily-packed, stressful whirlwind, not helped by conspiracies drifting around that London was about to enter some kind of drastic, Orwellian state of martial law. Never trust anyone whose primary source is their friend’s brother’s neighbour who ‘knows someone in the GOVERNMENT’. As we headed for the M4, I felt my exam motivation rapidly DISSOLVE, followed by my plans for a relaxing summer. Back home, I fluctuated between boredom and panic. I spent the first few days watching the cases of Covid-19 rise, waiting for the Prime Minister’s next announcement and frantically refreshing my EMAILS in the hopes that the UCL English department had sent news about summer exams. After a few weeks of being home, I learned to cope with the uncertainty of the situation. One of the things that helped me the most was structure. Creating a rough timetable of my day gave me security and made hitting goals more satisfying. This got easier after UCL let me know exactly what was required of me in my summer assessments, so I knew what needed to get done and could plan my TIME around it. This is what a typical day looked like as I settled into a lockdown routine… Explanation: |

What are columnar epithelium tissue?explain with diagram.Don't spam ! wrong answers will be reported immediately. |
|
Answer» Answer: The columnar epithelium is composed of epithelial cells that are column-shaped. The cell comprising the columnar epithelium is taller than it is wide. Its height is approximately four times its width. The nucleus in each cell is elongated and OFTEN found near the BASE. Some of them may have microvilli at the APICAL surface. When present, the microvilli increase the surface area (such as during absorption). Cilia may also be present. CILIATED columnar cells aid in the movement of mucus (as seen during mucociliary clearance). The columnar epithelium may be classified according to the number of layers that make it up. For example, a simple columnar epithelium is one that which is MADE up of a single layer of columnar epithelial cells. Explanation: Mark it as brainlist |

Discuss five kingdom classification with the help of a chart to show organism with their main character |
|
Answer» Answer: Explanation: The five kingdom CLASSIFICATION was proposed by R.H. WHITTAKER in 1969. The five kingdoms were formed on the basis of characteristics such as cell structure, mode of nutrition, source of nutrition and body organisation. It includes Kingdom Monera, Kingdom Protista, Kingdom Fungi, Kingdom Plantae, and Kingdom Animalia. Kingdom Monera: It includes prokaryotic cells lacking ORGANIZED nucleus and membrane bound cell organelles. Some of the Monerans are autotrophic andsome of them are heterotrophic forms. Kingdom Protista: Itincludes ALGAE, diatoms and protozoans. These are unicellular and the simplest form of eukaryotes exhibiting both autotrophic and heterotrophic mode of nutrition. Kingdom Fungi: Theseare multicellular, eukaryotic saprophytes. They include mushrooms, rhizopus and mucor. Some fungi are symbiotic forming an association with algal cells. These symbionts are termed to be lichens. Kingdom Plantae: Itincludes all the plants that are non-MOTILE,multicellular and eukaryotic organisms with their cell walls made up of cellulose. Kingdom Animalia: Itincludes all the animals that are motile multicellular, eukaryotic organisms with their cells possessing no cell walls. It exhibits species diversity. |
