3. Viruses containing RNA as their genetic information are called > Retroviruses.
4. In the six-kingdom classification system, bacteria are divided into two kingdoms, Eubacteria and Archaebacteria. The main difference in the cell structures of the two groups of bacteria is that > Archaebacteria do not have peptidoglycan in their cell walls, but Eubacteria do.
5. How do bacteria contribute to an ecosystem? > Some bacteria provide nutrients and raw materials for organisms in an ecosystem.
6. Which of the following roles of bacteria is not a benefit to human bodies? > acting as a pathogen

8. Antibiotics are often effective treatments for diseases caused by > bacteria.
9. What is one reason biologists have difficulty classifying protists? > Protists are incredibly diverse, and the different groups probably evolved independently of each other.

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 <u>41,02%</u> percent. The hematocrit value is <u>within the normal</u> 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

<u>In the question:</u>

\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!

Which of the following would most likely be key to gathering evidence that the RNA World hypothesis is valid?
muminat

Answer:

The answer is; Simulation of early Earth conditions and long-term study of the resulting molecules

Explanation:

It is believed that the first molecules on earth were made spontaneously through reaction spurred by energy from lightning and also the heat from the earth. It is believed that these molecules over time then formed polymers through the catalysis by metals in the oceans. These polymers were able to self-replicate and also act as enzymes since they were able to fold up. This hypothesis was coined by Carl Woese, Francis Crick and Leslie Orgel in the 1960s. To prove it, the then conditions of early earth need to be replicated, data collected, and analyzed.
