Explanation:
The autonomic nervous system is responsible for regulating the activity of glands, smooth muscle, and cardiac muscle. its under involuntary control, meaning it works without us telling it to do so. it's divided into two divisions: sympathetic and parasympathetic. in sympathetic division, here, the preganglionic fiber is short and the preganglionic fiber is long. sympathetic division is very important during emergancy situationd and is commonly associated with "fight or flight" response. it accelerates the heartbeat, dilates the bronchi, and inhibits the digestive tract. the parasympathetic includes cranial nerves and fibers. it is often referred to as the "rest and digest division". here, the preganglionic fiber is long and the preganglionic fiber is short. it promotes responses associated with a relaxed state, such as pupil contraction, digestion of food, and a reduced heart rate.
hope this helps!!
Answer:
Plants and animals could not live without nitrogen. It is an important part of many cells and processes such as amino acids, proteins, and even our DNA. It is also needed to make chlorophyll in plants, which plants use in photosynthesis to make their food and energy
Ans.
Lac (lactose) operon in a type of bacterial operon, which shows a cluster of genes that are regulated by a single promoter. It is composed of an operator, promoter, a terminator, and three structural genes (lacA, lacY, and lacZ), which are responsible for the transport and breakdown of lactose.
The lac operon is an inducible operon as it gets activated in the presence of lactose and expressed its functional genes in the form of proteins (or enzymes) for lactose metabolism.
Thus, the correct answer to be fill in first blank is 'inducible' and in second blank is 'lactose.'
