Children at ages 1 – 7 only
cares about playing. This is the range of age where utmost care is exhibited.
When they reach their pre-teen period, they slowly are aware of the
surroundings around them. By the time they reach their teenage years, they are
now conscious of their physical appearance and are conscious. You must guide
them what they are seeing and point out things that are good or bad.

Answer: c. 2 pyruvate molecules
Explanation:
Glycolysis is the first step it the cell respiration cycle. It turns one molecule of glucose into two molecules of pyruvate by a series of reactions catalyzed by different enzymes.
It starts by using 2 ATP to turn glucose into fructose-1,6-bisphosphate, which then divides in two and releases 4 ATP when it turns into two pyruvate molecules.
Thus glycolysis consumes 2 ATP and releases 4 ATP (giving a net gain of 2 ATP) and 2 pyruvate molecules.

Answer:
Dust bowl resulted from extreme drying and loosening of the soil that resulted in soil erosion by wind. Thus, it can be related that poor agricultural practices like over plowing , over grazing and leaving the land barren are human activities that must have contributed to the dust bowl.
Explanation:
- Dust bowl is referred to a period in early twentieth century when the the American and Canadian prairies faced severe dust storms.
- These dust storms resulted from severe drought and failure of practices to prevent soil erosion.
- Several people and livestock died as a result of choking.
- Over plowing, removal of top soil and small grasses exposed the soil to eroding winds and caused the dust storms.
Answer:
Increasing the alveolar ventilation rate will increase the partial pressure of oxygen in the alveoli.
Explanation:
Alveolar Ventilation rate is the rate of air flow in the alveoli of the lung during normal breathing. It is measured in milliliters of air per minute (mL/min). The alveolar ventilation rate is an important factor in determining the concentrations (partial pressures) of oxygen and carbon dioxide in the functioning alveoli.
A high rate of alveolar ventilation, would result in a rapid influx of oxygen-rich air and efflux carbon dioxide-filled air from the alveoli. This ultimately results in an increase in the concentration of oxygen and a decrease in the concentration of carbon dioxide within the alveoli.
Effects of alveolar ventilation on partial pressures of alveolar carbon dioxide and oxygen (PACO₂ and PAO₂)
If the alveolar ventilation rate is increased (and carbon dioxide production is unchanged), then the partial pressure of carbon dioxide in the alveoli, PACO₂ will decrease.
If the alveolar ventilation rate increases, then the partial pressure of oxygen in the alveoli, PAO₂ will increase.
