Answer:
The activation energy required for an exploding firework is less than the activation energy required for a burning candle.
Explanation:
I did this in class. The height of the activation is lower for the firework than the burning candle.
Answer:
Thus, during the Citric Acid cycle, the breakdown of glucose into carbon dioxide is completed. There are four redox reactions, three of which yield reduced NADH and one FADH2. Thus, the oxidation of glucose is completed in the Kreb's cycle
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:
Of the 23 pairs of chromosomes in any normal human cell, the first 22 pairs provide directions for an individual's body and brain development. Scientists now estimate that about half of a person's personality traits and cognitive abilities can be traced to genetic influence and that psychological disorders arise from the interactions of many genes.
Explanation:
Chromosomes are small molecules that have the ability to carry all the genetic information needed to form a living being. These chromosomes are donated by an individual's parents and are used to form 23 pairs that determine all the internal and external characteristics of an organism. Among these 23 pairs, one pair will be responsible for determining the individual's gender, and the other 22 pairs will be responsible for the instructions that will make up the entire body and brain of the individual. Many scientists believe that chromosomes are responsible for even a part of a person's personality traits and that the genes they carry are directly related to the existence of psychological disorders.
