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.

My following prediction was that Glass A will have the least foam rise, which according to Jared's table was correct. However, the rest of the results did not match my predictions.

When a cell prepares to divide, the chromatin condenses into rod-shaped structures called?

MA_775_DIABLO [31]

Answer:

Chromosome

Explanation:

As the cells prepare for cell division, several events occur. During the prophase of mitosis, the thin threads of chromatin are condensed into rod-shaped visible structures. The process of compaction of chromatin gives rise to chromosomes. Chromosomes are rod-shaped structures made up of DNA and packaging proteins. Since DNA replication has already occurred during the S phase of interphase, each chromosome has two sister chromatids.
