Temperature and pH levels are both correct
The different degrees of sleep and wakefulness through which newborns cycle, ranging from deep sleep to great agitation, are called states of arousal. These states are regular sleep, irregular sleep, drowsiness, quiet alertness and crying. About eight to nine hours each of an infant's day is dedicated to regular and irregular sleep. So, most of the time of the infant is spent in these states. These are the states where the brain of an infant is developing the important connections for growth and survival. Crying is the means for infants to communicate their needs. Different type of cries would represent different needs of the infant.
Answer: supersaturated
Explanation: A supersaturated solution is a solution in which the dissolved solute is more than the solvent can hold at that particular temperature.
A solution is a substance which sontains a dissolved solute. A solution can be saturated, unsaturated or supersaturated.
A saturated solution contains the maximum amount of dissolved solute a solvent can hold at that temperature.
An unsaturated solution contains less amount of solute than the solvent can hold at that temperature, this means that more solute can still dissolve in the solution.
A supersaturated solution contains more solute that can be dissolved in the solvent at that temperature.
Answer: B
Explanation:
Photosynthesis uses CO2 and water to make oxygen and glucose.
6CO2 + 6H2O → C6H12O6 + 6O2 This is the chemical reaction that occurs. Products are on the right and we can see glucose and oxygen are formed.
