You just came back from a class in which the topic was egocentrism in the preoperational stage. You have a 4-year-old and thought that you would see whether what you learned was accurate. You are sitting directly across from your child and ask her to look at the front and back cover of her favorite book. After she does this, you ask her to describe "the part of the book I am looking at." What does she tell you?
Solution 1

Question -
You just came back from class in which the topic was egocentrism in the preoperational stage. You have a 4-year-old and thought that you would see if what you learned was accurate. You are sitting directly across from her and ask her to look at the front and back cover of her favorite book. After she did this you asked her to describe "the part of the book I am looking at." What does she tell you?
a) how many pages there are in the book
b) what she sees
c) what you see
d) what the story is about
Solution
As per Piaget's theory of cognitive development, when a child is at the preoperational stage he/she is able to think only at symbolic level and cannot use his/her cognitive thinking.
He/she is unable to derive senses or meaning associated with symbols and also his/her communication is egocentric which means they cannot think from the perspective of other people.
Hence, option B is correct

Answer:
The correct answer is - option B.
Explanation:
The head tilt or lift chin maneuver is the method that helps in the prevention of the blocking the airways by obstructions due to tongue more often. It is the procedure which is performed by the lifting the chin backwards or tilting the head towards back so the applied pressure that cause the ventilation normal again in the patient. If the person is not showing any improvement one should ease his/ her head forward a little so the pressure could be released.
Thus, the correct answer is - option B.
Answer:
2.688 x 10^-6 oz
Explanation:
The recommended amount of blue fish in pregnant women is 0.5 pounds once a month. So, 0.5 pound is solely 8 ounces. If 0.336 oz of mercury is present in 1 x 10^6 oz of fish then (8 / 1000000) x 0.366 = 2.688 x 10^-6 oz is the amount of mercury a pregnant woman will consume if she eats half a pound of blue fish one per month.
Answer:
secretion
Explanation:
Epithelial cells are usually cells located or found outside the body, skin, urinary tract, vessels, cavities, and organs of the body, and have special modifications of their surfaces which depends upon the specific roles they perform and where they are found. However, many types of epithelial cells perform a common function of secretion. Epithelial cells are closely packed together.
Answer:
The correct answer is d. atmospheric O2 levels.
Explanation:
Cyanobacteria were considered to be the first aerobic organism on earth. Before the appearance of cyanobacteria, the earth atmosphere was reducing. Cyanobacteria were able to use light energy and perform photosynthesis.
As oxygen was the byproduct of photosynthesis it is released in the atmosphere and that increased the level of oxygen in world. Due to this oxygenic environment is created on the earth. Chloroplast in plants which helps in photosynthesis shows similarities with cyanobacteria.
So cyanobacteria changed the atmosphere on earth because they increased the atmospheric O2 level.
Answer: D
Cyanobacteria changed the atmosphere on early Earth because of their unique property- their ability to turn into increased atmospheric O2 levels.
Hope this helps!
Answer:
Four
Explanation:
Four photons are sufficient to generate one glucose molecule and necessary ATP. In photosystem II, a photon initiates the process of photosynthesis after the splitting of water molecule and then travels it through the electron transport chain thereby pumping hydrogen ion. An electrochemical gradient is formed which allows ions to flow from thylakoid into the stroma and generate ATP and sugar molecule. A second photon is then absorbed in the photosystem I to form NADPH molecule which provides energy for Calvin cycle.
Answer: Chemiosmosis
Explanation
Photosynthesis and respiration generate ATP by thesame mechanism, Chemiosmosis. In plants cells it occurs in the chroplast and mitochondrial in animal cells. An electron transport chain is assembled in a membrane pumps protons across the membrane as electrons are passed through a series of carriers that are progressively more electronegative.
In both kinds chloroplasts and mitochondrial electron transport chain pump protons (H+) across a membrane from a region of low (H+) concentration to high H+ concentration. The protons then diffuse back across the membrane through ATP synthase, driving the synthesis of ATP.
Answer:
Taking away land for preserving the environment from people is seen as a punishment instead of this government must give incentives to people to maintain the their lands that have resources sustain ably thereby promoting sustainable ownership
Explanation:
It is believed that instead of punishments, private properties must be incentivized in order to conserve resources and encourage sustainable development.
Lands are being privatized in order to provide direct benefits of the environment to the people. In lieu to that people are expected to take care of the land and treat the surrounding environmental resources respectfully. Government has also come up with special plans to incentivize the owner for promoting and maintaining sustainable land ownerships instead of taking up the lands that have endangered species
Answer:
Both gene expression and DNA micro array study about the expression of gene during different stages of development.
Explanation:
The main purpose of gene expression studies is to determine the level of mRNA expressed at different stages of transcription in a tissue or at different stages of cellular development. If a gene is not “ON” during synthesis of RNA and protein, then the desired proteins are not produced. Such studies allow us to turn on such genes.
DNA microarray assays easily identify and determine the network of gene expression across the entire genome. The common application of DNA microarray include – mutation analysis and detection, assessment of gene cop, immunoassays etc.
Answer:
Answer is Serous membrane.
Explanation:
The serous membrane is known to be or can be described as a thin membrane usually consisting of two layers which are separated by a space filled with serous fluid, which is derived from the serum.
The serous membrane are lying the cavity of some certain internal organs of the body, such as the lung and the heart. The fluid produced by the serous membrane,[ serous fluid], serves as lubricant to reduce friction occurring from muscle movement.
Examples of serous membrane are peritoneum and pericardium.
Answer:
a. First Step: The sugars are broken down to simple glucose molecules and the proteins and lipids are broken down to acetyl-CoA molecules. No energy is produced in this first step.
b. Second Step: Glycolysis converts the glucose to two molecules of pyruvate. Six ATP molecules are produced in this step.
c. Third Step: Oxidation of each pyruvate produces two molecules of acetyl-CoA. Six ATP molecules are produced in this step.
d. Fourth Step: Two acetyl-CoA molecules go through the Krebs (citric acid) cycle. Twenty-four ATP molecules are produced through this process.
e. All of the above steps are part of the break down of the candy bar's macromolecules.
