maks197457 [2]

Answer:

One-fifth

Explanation:

There is a serious and major health issue occurring within individuals of the youngest generation of Americans, with an endangering impact on the nation's future.

The Centers for Disease Control and Prevention reveals that 1 in 5 Northen American children age within 3 to 17 — approximately 15 million — have a diagnosable mental, emotional or behavioral disorder within a certain year.

Recent studies shows that critical depression level is increasing amidst the teens, mostly girls, and the death level amidst girls as attained a 40-year rise in 2015.

Mental health problems might gradually begin much earlier than how it is examined to be as indifferent depression in toddlers may result in increase depression as time proceed in life with increased chances that result in depression and bipolar disorder is nearly twice within age 13 to 18.

Hence, the reason why The Child Mind Institute is gathering brain scans from 10,000 children and teens, with the agenda to observe biological markers of psychiatric illness so as to boost the diagnosis and cure of mental disorders.

After the gram staining procedure, you realized you went too fast and have forgetten to apply the 95% ehtanol. What might be the
LekaFEV [45]

Answer:

In gram staining, 95% ethanol is used to destain the gram-negative bacteria but gram-positive bacteria do not get destain because peptidoglycan layer in gram-positive cell wall does not allow crystal violet- iodine complex to come out of the cell wall.

Gram-negative bacteria do not have peptidoglycan cell wall and so crystal violet comes out of the cell wall by using 95% ethanol because ethanol dissolves the lipopolysaccharide membrane of gram-negative bacteria and allow the dye to leak out.

Therefore if I forgot to apply 95% ethanol than crystal violet dye will not come out of the lipopolysaccharide cell wall of gram-negative bacteria and it will appear violet under the microscope.

Luden [163]
When both daughter cells are the same cell type, this is called symmetric division. That's true whether they continue being stem cells or become something new. When one cell stays a stem cell and the other differentiates, it's called asymmetric division. This happens about 30 percent of the time.

2 Points<br>Which of the following is a good reason to use a simulation in an<br>experiment?​
oksian1 [2.3K]

One of the good reason to use simulation in an experiment is to predict the outcome of an event in the real world.

Explanation:

Simulation is a programming software which helps in imaging or easy understanding of any experimental concept virtually. For example, if we enter the details regarding an element, the simulation can draw the structure of that element. Also it may predict the working of the bonds and other parameters in different conditions based on classical and quantum theoretical laws. So a researcher can compare the results obtained from simulation and also from experimental results.

In other words, simulation will help a researcher to have an assumption about the behavior of the sample in real world conditions.
