Cellular respiration transforms glucose and oxygen into carbon dioxide, water, and energy.
C6H12O6 + 602 = 6CO2 + ?H20 + Energy
Based on the law of conservation of matter what is the missing coefficient for water?
1. 6
2. 8
3. 4
4. 2
Answer:
6
Explanation:
The left side of the equation has 6 molucules.
C6H1206
The equation must be balanced so it must be 6 for the coeffciet of water.
On the basis of the law of conservation of matter, the missing coefficient for water is 6 in the process of cellular respiration. Thus, the correct option for this question is 1.
What is Cellular respiration?Cellular respiration may be defined as a chemical process through which the breakdown of food in the cell occurs with the liberation of energy in the form of ATP. It involves the series of chemical reactions by which living organisms produce energy through the oxidation of organic substances.
The entire process of cellular respiration transforms glucose and oxygen into carbon dioxide, water, and energy. According to the process of balancing chemical equations, the number of the hydrogen atom is equal to 12, then the water molecule comprises H20, so there is a need of inserting 6 to complete the missing coefficient for water.
Therefore, the missing coefficient for water is 6, thus, the correct option for this question is 1.

What challenges do you envision that would hinder the progress of a flipped
classroom?
Answer:
Explanation:
Need to Know. How are you creating a need to know the content that is recorded? Just because I record something, or use a recorded material, does not mean that my students will want to watch, nor see the relevance in watching it.
Engaging Models. One of the best way to create the "need to know" is to use a pedagogical model that demands this. Whether project-based learning (PBL), game-based learning (GBL), Understanding by Design (UbD), or authentic literacy, find an effective model to institute in your classroom.
Technology. What technology do you have to support the flipped classroom? What technology gaps exist that might hinder it? Since the flipped classroom is about recorded video, then obviously students would need the technology to do this.
Reflection. Every time you have students watch a video, just like you would with any instruction

Which of the following terms best describes what Ricky is experiencing?
a. Sensitization
b. Habituation
c. Operant conditioning
d. Extinction
Answer:
吧b
Explanation:
Ricky has been struggling to sleep due to the loud noise of police sirens at night, but has noticed that the sirens have been disturbing his sleep less as he gets used to the noise. Ricky is experiencing habituation.
What is habituation?habituation is a type of response where complete elimination of a particular response or zero frequency of occurrence occur.
If the stimulus continues for an additional number of trials, although no changes occur but the response will exhibit lower levels of recovery.
Habituation is a non-associative learning in which an automatic decrease in the intensity of a response occur which is repetitive, weak stimulus, without serious consequences, for example, ignoring stimuli
Habituation defines as the fading of the response over the course of monotonous stimulation, and sensitization refers to processes of increased response.

If two parents are contributing genetic material to their offspring, why don’t the genes and chromosomes double in each generation?
Chromosomes and genes do not double in each generation in se-xual reproduction because they are usually halved before being donated to offspring.
What is meiosis?Meiosis is a reductional division involving s-ex cells. Meiosis happens prior to se-xual reproduction.
In other words, the halving of chromosomes takes place during the formation of gametes. Thus, gametes usually carry half of the chromosome and only a copy of each gene of the parents.
When two gametes combine to result in a zygote, their chromosomes and genes also pair up to arrive at a normal number of chromosomes and genes.
