Option are not provided in the question. The complete question is:
Which activity would help decrease the greatest carbon-releasing activity in US homes?
limiting time in hot showers
wearing layers of clothing
turning off lights when leaving a room
unplugging electronics when not in use
Answer:
wearing layers of clothing
Explaination:
Increasing carbon emission in environment is one of the major cause of global warming and climate change. There are several human activities that contribute to increament in carbon-releasing such as burning of fossil fuels, industrial manufacturing and deforestation et-cetra.
Wearing layers of clothes can decrease the greatest carbon-releasing activity in US homes because the weather of US is cold and people use a lot of fossil fuel to make their surrounding warm. Wearing layered clothes will help US people to feel warm and reduce the burning of fossil fuel which is major contributor to carbon emission.
Hence, The correct option is wearing layers of clothing.
Meiosis is the process of reduction of diploid cells to haploid cells and it involves two process meiosis 1 and meiosis 2.
Meiosis 1 involving the crossing over of the genetic material between the pair of chromosomes whereas meiosis 2 involves the separation of the chromosomes into sister chromatids.
Answer:
