Answer:
The correct answer is B transcription factors.
Explanation:
Transcription factor are specific regulatory protein also known as sequence specific DNA binding proteins which regulates the process of transcription in eukaryotic cell.
Transcription factors may either turn on or off the expression of a particular gene to ensure that they are expressed in right cell along with perfect amount and manner.
Transcription factor such as helix turn helix ,leucine zipper, zinc finger play an important role in regulating the activity of many proteins such as DNA ploymerase, helicase
Answer:
Air travel is usually the largest component of the carbon footprint of frequent flyers. A single return flight from London to New York – including the complicated effects on the high atmosphere – contributes to almost a quarter of the average person’s annual emissions. The easiest way to make a big difference is to go by train or not take as many flights.
2 The second most important lifestyle change is to eat less meat, with particular emphasis on meals containing beef and lamb. Cows and sheep emit large quantities of methane, a powerful global warming gas. A vegan diet might make as much as a 20% difference to your overall carbon impact but simply cutting out beef will deliver a significant benefit on its own.
Organs.
As with organelles, organs serve a specific function.
There are choices for this question namely:
1 Cesarean section
2 Vaginal delivery with forceps extraction
3 Vaginal delivery with vacuum extraction
4 <span>Fetal scalp electrode

The correct answer is "cesarean section". In cesarean section, we are preventing the vertical transfer of the virus from the mother to the baby by bypassing the vaginal mucosa (which has secretions, potentially with high viral load). Fetal scalp electrode, on the other hand, is not a method of delivery.
