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).
Answer:
water is constantly moving across the earth. The water is strong enough to break down soil in tiny pieces. What’s happening is a process called erosion. Erosion is: the process of eroding or being eroded by wind, water, or other natural agents.
"the problem of soil erosion".
Water also carries sand and moves it around, this obviously changes the shape of the earths surface!
Explanation:
Answer;
-Birth rate
Explanation;
-The birth rate is the total number of live births per 1,000 in a population in a year or period. For example; in one year, 35 giraffes are born to a population.
-A population is defined as a group of individuals of the same species living and interbreeding within a given area. Members of a population often rely on the same resources, are subject to similar environmental constraints, and depend on the availability of other members to persist over time. Scientists study a population by examining how individuals in that population interact with each other and how the population as a whole interacts with its environment.
Answer:
Ribose
Explanation:
Ribose, also called D-ribose, five-carbon sugar found in RNA (ribonucleic acid), where it alternates with phosphate groups to form the “backbone” of the RNA polymer and binds to nitrogenous bases.
