In your own words, describe the theory of plate tectonics and the action that occurs at plate boundaries.

Katen [24]

Well, put this in your own words.

At plate boundaries, the tectonic plates rub against each other. They either slide over one another, causing earthquakes; or they smush into each other making mountains or valleys.

When individuals experience fear and pleasure, what part of the brain has been stimulated?

Nataliya [291]

The limbic system of the brain gets stimulated when an individual experiences fear and pleasure.

The limbic system is a part of our brain which is responsible for the regulation of our emotional and behavioral responses, especially the ones we need for our survival. The structures of the limbic system are embedded deep in the brain. The two major structures of the limbic system include the hippocampus and the amygdala. The hippocampus helps us associate emotions and senses with different memories. The amygdala plays a pivotal role in managing our strong emotions like aggression, fear and pleasure. It also helps us in making new memories.

If 32 packed volume units of cells are separated from 46 volume units of plasma from a blood sample, the haematocrit is _______

nordsb [41]

Answer:

If 32 packed volume units of cells are separated from 46 volume units of plasma from a blood sample, the hematocrit is 41,02% percent. The hematocrit value is within the normal range.

Explanation:

Hello!

Hematocrit (or packed cell volume -PCV-)is defined as the percentage of red blood cells (vol%) in a blood sample. One common method of determining it is by centrifuging a heparinized blood sample in a capillary tube at 10 000 RPM for five minutes. This separates the blood sample in two layers, formed elements (RBC and WBC) and Plasma.

The length of the layers is directly measured from the tube and represents the volume of packed cells and plasma. Since the number of white cells is negligible compared to the number of red cells, the formed elements are considered to represent the red blood cells.

The hematocrit can be calculated as the volume of packed cells divided by the total volume of the blood sample.

$\frac{PCV}{TOTAL(pcv+plasma} * 100$

In the question:

$\frac{32}{32+46} * 100$ = $\frac{32}{78} * 100$ = 41,02%

In humans the normal hematocrit range is 40,7% to 50,3% for men and 36,1% to 44,3%. Taking these reference values into consideration, this sample is within the normal range.

I hope you have a SUPER day!
