Question 22 (Essay Worth 3 points) (02.01 HC) A prediction of the theory of Plate Tectonics is that new volcanoes can form at th

e boundary of two plates as magma seeps between them. To test this hypothesis, a scientist makes a map of existing volcanoes along a tectonic plate and measures the number of new volcanoes that appear over a decade. What would be the expected result of the experiment? How would you interpret the results if the scientist observes no new volcanic activity?

Answer:

What would be the expected result of the experiment?

For the drawing of the map part, the scientific will find that effectively, a very large number of volcanoes are located near the meeting points of tectonic plates. The volcanoes that aren't now at the edge of the plate were most probably at the moment of their formation, and were moved away by the movement of the plate.

But I doubt the scientist would be able to identify many new volcanoes, because the creation of a volcano isn't something happening overnight.

How would you interpret the results if the scientist observes no new volcanic activity?

I would say that does NOT invalidate the theory because the observation period is extremely short.  10 years is an insignificant amount of time geologically speaking... the study would have to be conducted over at least 1,000 years to maybe have some results at all.   Just imagine how many volcanoes there would be if a new one was created every 10 years along the side of a tectonic plate.

A bacterial sample has a cell density of 1.85 x106 CFU/mL. What plate dilution should yield a countable plate? Which two dilutio
insens350 [35]

Answer:

Explanation:

Bacterial count in stock- 1.85x10^6 cfu/ml

Dilution methods

Take 100 uL or (0.1ml) from stock and add to 900ul (0.9ml) saline and mixed it- this makes 10^1dilution.

Now take 100ul from 10^1 dilution and add to next 900ul saline this is 10^2 dilution, similarly do upto 10^5 dilution.

Then take 100ul from 10^ 4 and 10^5 dilution seperately and plate on LB agar plate seperetely and count the colonies.

Cfu/ml formula= (No.of colonies x dilution factor)/0.1 ml

So suppose, 18 colonies formed on 10^4 dilution then total no. Of cells in stock will be 18x10^4/ 0.1= 18x10^5 cfu/ml.

If we dilute 10^4 or 10^5 that's leads to colony count of 18-19 colonies on 10^4 dilution while 2 colonies should come on plate of 10^5 dilution.

What is the first step in the treatment process for addiction where the addiction is systematically and safely withdrawn?
solniwko [45]

Answer:

Medical Detoxification

Explanation:

Detox or detoxification is the process of safely and systematically withdrawing from a substance such as drugs or alcohol. For many, it’s an important first step in recovery, allowing the body to withdraw from potentially dangerous substances without risking hospitalization.

Many drugs have significant withdrawal symptoms once you quit using them, you tend to experiencing considerable discomfort and pain. Without proper medical attention, these withdrawal symptoms can become dangerous to your health and even become life‐threatening.

Objectives of Detoxification include

1. Evaluation‐the testing of substances in the bloodstream, their concentrations and any co‐occurring mental or physical conditions that may accompany substance abuse as well as other medical and social assessments.

2. Stabilization‐assisting patients through the withdrawal process towards a stable and substance‐ free state.

3. Fostering Entry into Treatment‐preparing clients to enter formal treatment and providing encouragement and support.
