Answer:
a. low birthweight
Explanation:
Normal gestation period is around 40 weeks before babies are being born with fully developed system and are capable of leading a normal life without intensive care. Preterm or premature birth are births that occur before the 37th week of pregnancy.
Average weight of full-term babies (babies born between 37–40 weeks) is around 7 pounds (3.17 kg) at birth, with a normal weight ranging from 5 lb 8 oz to 8 lb 13 oz.
Full-term babies who weigh below this range could be said to have low birth weight.

Plasmid vectors are used to transmit gene segments. Plasmid vectors are used as "cloning vectors" which are small genetic pieces taken from an organism's cell. These are used for maintaining stability when foreign DNA gets inserted into the cell itself.
The group in an experiment that all the conditions stay the same is the control group.
As a greenhouse gas that absorbs heat, CO2 raises the temperature of the atmosphere. We refer to this as global warming. The glaciers will melt more quickly as the world's temperature rises, raising sea levels and bringing on disaster. More power is consumed for air conditioning as the temperature rises, which further raises the air's CO2 level.
Since coal is the primary fuel utilized in the creation of power. This creates a vicious cycle.
