Predict the potential impact of severe solar weather on Earth's communication systems.

DaniilM [7]

Severe solar weather has the potential to cripple communication systems on earth.

Solar weather occurs when solar activity increases. Sudden bursts called Coronal Mass Ejections are the main culprits of solar weather. These CME's release bursts of plasma and charged particles straight towards the Earth. Once these particles impact the upper atmosphere they cause geomagnetic storms that interfere with radio signals and communication and possibly fry electronic devices.

Severe geomagnetic storms can cause devastation for Earth's communication network. These storms interfere with radio communication, meaning that phone service, radio broadcasts, and even internet connection would be disabled. Even worse, these storms can often damage electronics, specifically satellites. Damage to satellites can cause severe damage to modern-day infrastructure.

The blood group from the observation is O negative.

The blood groups can be determined practically with the help of anti-serums.

One of the groups into which people or their blood can be classified based on the presence or absence of particular antigens in the blood (such as those labelled A, B, AB, or O) is called as blood group.

There are 4 main blood groups (types of blood) – A, B, AB and O.

Red blood cells, white blood cells, and platelets are contained in a fluid called plasma, which is the blood. Antibodies and antigens found in the blood help identify your blood group.

Plasma contains proteins called antibodies. They are a component of your body's built-in defenses. They identify alien objects, like bacteria, and notify your immune system, which then eliminates them.

Protein molecules called antigens can be detected on the outer layer of red blood cells.

The ABO system distinguishes 4 major blood types:

Red blood cells with blood group A antigens have anti-B antibodies in their plasma.
B antigens and anti-A antibodies are present in the plasma in blood group B.
Blood group O - has both anti-A and anti-B antibodies in the plasma but no antigens.
A and B antigens are present in blood group AB, however there are no antibodies.

So, as the question tells that Sara's blood doesn't coagulate with anti serum a, b and rh this means that her RBCs have none of the proteins on its surface leading to Blood group O negative.
