Answer:

<h2>1.45 + 3.55 = 5.0 (total blood volume);  1.45/5.0 × 100 = 29% (low),</h2>

Explanation:

HCT is calculated as:

HCT = Volume of red blood cells / (Volume of red blood cells + volume of plasma) x 100  

1.45 + 3.55 = 5.0 (total blood volume);  1.45/5.0 × 100 = 29% (low), normal range for an adult female HCT  ranges from 38 to 46% (some sources claim 34.9-44.5%).

*for calculating this, one must know two of these three values: packed cell volume, total blood volume, plasma volume.

Total blood volume = Packed cell volume + plasma volume.

How do scientists explain the discovery of crinoids in the Wasatch Mountains?
Nostrana [21]
<span>The mountains were once seas. The land was forced up by tectonic motion when the mountains were formed. The Sahara also used to be a sea and has a valley full of the fossilized remains of an extinct species of whale. It is generally agreed upon that two plates colliding caused the uplift that created the mountainous zone. Same for the Himalayas.</span>

What is the first way in which biology researchers present the results of their latest research?
Inga [223]
Generally people would say that the result are published in journals, and it is true that Journals are often the first opportunity for many people to read about those results.

However, it takes a long time to publish in a journal, and people often present their results to a smaller audience at a conference before the journal is ready.
