A bacillus or bacilliform bacterium is a rod-shaped bacterium or archaeon.
velocity= distance / time
your distance is 180 miles
your time is 3 hours
180 divided by 3 = 60
Answer:
Mutations are permanent changes in the DNA due to changes in nucleotide sequences. Mutations that cause addition of extra nucleotides in a nucleotide sequences are known as frameshift mutations
The correct answer is: A) pontine respiratory centers
The respiratory centre in the pons is responsible for generating and maintaining the rhythm of respiration. Besides this elementary function, it also has the ability to adjust respiration rhythm in c response to physiological changes. Respiratory centre consists of three major respiratory groups of neurons:
• The dorsal respiratory group (DRG)- initiates inspiration (inhalation)
• the ventral respiratory group (VRG)-responsible for exhalation
• Pontine respiratory group- includes the pneumotaxic (controls both the rate and the pattern of breathing) and apneustic centers (promotes inhalation by sending signals to dorsal group).
