Like the right atrium, the left atrium also has valve in its auricle.

<h3>What is heart?</h3>

The heart is defined as the major organ of the cardiovascular system which is used by the body to pump blood through out the cardiovascular system.

The heart is made up of the following:

Left atrium,

Left atrium,

Right ventricle and

Right ventricle.

Both the left and right atrium are separated from the ventricle by the valves which helps to prevent the back flow of blood.

Classify each description as applying to organisms in one, several, or all of the domains of archaea, bacteria, and eukarya.

noname [10]

The correct descriptions of each of the organisms are as follows:

Archaea:

cells do not have a nucleus
cells contain genetic material
most inhabit extreme environments.

prokaryotes

Bacteria

cells do not have a nucleus
prokaryotes

E. coli

Eukarya

eukaryotes
cells have a nucleus
many are multicellular
cells have membrane-bound organelles
plants

Archaea and Bacteria

cells do not have a nucleus
cells contain genetic material
prokaryotes

All three domains

cells contain genetic material

<h3>What are living organisms?</h3>

Living organisms are those things that have life in them.

Living organisms are classified into the following domains:

archaea,
bacteria, and
eukarya

A common feature of all three domains is that they all have genetic material.

In conclusion, living things are classified into three domains.

Two ice skaters stand facing each other. The first skater has a mass of 100 kg and the second has a mass of 50 kg. They push eac

olga_2 [115]

The second skater accelerates at 6 $m/s^2$ to the right.

Let the first skater be F.

Let the second skater be S.

<u>Given the following data:</u>

Mass of F = 100 kg

Mass of S = 50 kg

Acceleration of F = 3 $m/s^2$

To find the acceleration of the second ice skater, we would apply Newton's Second Law of Motion:

Mathematically, Newton's Second Law of Motion is given by this formula;

$Force = Mass$ × $acceleration$

Substituting the given values, we have;

$Force = 100$ × $3$

<em>Force </em><em>= </em><em>300 Newton</em>

<u>Note:</u> The same force is acting on the two ice skaters and the second ice skater would be pushed in the opposite direction (right).

Now, we would find the acceleration of the second ice skater:

$Acceleration = \frac{300}{50}$

<em>Acceleration of S </em><em>=</em><em> 6 </em> $m/s^2$ <em />

Therefore, the acceleration of the second ice skater is 6 $m/s^2$ to the right.
