Plant kept in continuous light will live longer, because it will be able to produce oxygen required for its respiration by the process of photosynthesis. Plant remaining in the dark will not photosynthesize and hence it will finally die due to no availability of oxygen.

No photosynthesis will occur in the plant kept in dark due to absence of sunlight. So the plant kept in sunlight will survive and plant kept in dark will not survive as photosynthesis does not occurs.

Sexually transmitted diseases (STDs), or sexually transmitted infections (STIs), are infections that are passed from one person to another through sexual contact. They are usually spread during vaginal, oral, or **** ***. But sometimes they can spread through other sexual contact involving the *****, ******, mouth, or ****. This is because some STDs, like herpes and HPV, are spread by skin-to-skin contact. Some STDs can be passed from a pregnant person to the baby, either during pregnancy  or when giving birth. Other ways that STDs may be spread include during breastfeeding through blood transfusion , or by sharing needles.

Washing soda(Na2CO3.10H2O) is synthesized through Solvay's process. It involves the reaction of sodium chloride(NaCl), ammonia(NH3) and carbon dioxide(CO2) in water. Carbon dioxide(CO2) involved is produced through calcium carbonate(CaCO3) and the calcium oxide(CaO) left is used in recovering ammonia(NH3). At first, sodium bicarbonate(NaHCO3) is obtained which is then converted to sodium carbonate(Na2CO3) on heating. Finally, washing soda(Na2CO3.10H2O) is produced by the recrystallization of sodium carbonate(Na2CO3).
