During which type of solar weather would one predict power grid operations on Earth could degrade?
Verdich [7]

The type of solar weather during which we can predict power grid operations on Earth to degrade is Coronal Mass Ejections

Coronal Mass Ejections are what we call the sudden bursts of plasma and charged ions released from the suns solar corona. These CMEs tend to occur during solar flares and release the charged ions into the solar wind.

Despite the presence of all of the options during a solar storm, the correct option is option 3, Coronal Mass Ejections because without the presence of the CME , solar wind and flares are not dangerous to the Earth. The charged ions from the CME collide and warp the Earth's magnetic field, removing it's protection and causing <u>power grid failures and radio communication disruptions throughout the Earth.</u>

7. Which land biome has the greatest diversity of plant species, and which has the least? a.grassland: most; tundra: least b.rai
Aleks [24]

A) Grassland: Most & Tundra: Least - This answer is incorrect, because grassland biomes are definitely not known for their high plant diversity. As one could imagine, the primary plant found here is grass (and large shrubs.)

B) Rain Forest: Most & Taiga: Least - While this answer is pretty close, a taiga biome does not hold the least amount of plant diversity.

C) Rain Forest: Most & Tundra: Least

D)Temperate Forest: Most & Taiga: Least: As mentioned in B, Taigas do not hold the least amount of plant diversity.

ANSWER:

C) Rain Forest: Most & Tundra: Least

The graph below shows the percentage of acres in the United States that is dedicated to genetically engineered crops.
Alexus [3.1K]
The best description of the graph is that "the percentage of of acres that is dedicated to genetically engineered crops grew from 1996 to 2005"
The y-axis of the graph has the percentage of acres dedicated to genetically modified crops, while the x-axis has the years. The four lines show the four types of crops that are grown. All of the lines are observed to have a direct correlation between the values of y and x, so the percentage of acres dedicated is increasing with time.

Which of the following best describes the process of transcription during protein synthesis?
jonny [76]

Answer:

The answer is 'D'. Transcription is the process by which a single stranded mRNA is formed from the double stranded DNA.

Explanation:

The central machinery of biology involves three processes- replication, transcription and translation. The process by which DNA doubles itself is called <u>replication</u>. In translation, protein is formed from the messenger RNA or mRNA. The major steps involved in transcription are:

  1. <em>Initiation</em>
  2. <em>Elongation</em>
  3. <em>Termination</em>

In the process of translation, amino acids bind together in the <u>ribosome</u> to form a polypeptide chain.
