Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).
Ricin comes under the category of functionally related toxins, in a combination known as RIPs (ribosome inactivating proteins). This disables ribosomes and stops the process of protein synthesis.
They directly associate with and inactivate the ribosomes or modify the factors taking part in the process of translation, generally the elongation step. These proteins bring about depurination of adenine at position 4324 in the 28 S rRNA.
This further inhibits the generation of a critical-stem-loop configuration to which the elongation factor is considered to combine at the time of the translocation step of translation. The ultimate outcome of this activity is the complete inhibition of cellular translation.
Under a microscope, gram-positive bacteria (when dyed with the gram stain) appear in purple-colored structures due to the peptidoglycan cell wall.
<h3>What are gram-positive bacteria?</h3>
Gram-positive bacteria are microorganisms (bacteria) that may be colored with crystal violet stain due to the presence of a peptidoglycan-based cell wall.
In conclusion, under a microscope, gram-positive bacteria (when dyed with the gram stain) appear purple-colored structures due to the peptidoglycan cell wall.

Answer: DNA polymerase I is able to proofread; DNA polymerase III is not.
Explanation:
Escherichia coli is a gram negative anaerobic bacteria that is found in the gastrointestinal tract of and humans and animals. Escherichia coli has 5 types of DNA polymerase.
a. Polymerase I is used to repair any damaged DNA and proof reading
b. Polymerase II is used in proof reading, DNA Replication and repairs.
c. Polymerase III is primarily responsible for DNA replication. It also has the ability to proof read.
d. Polymerase IV is used to change genetic information of Escherichia coli.
e. Polymerase V is used in DNA repair in Escherchia coli.
The circular fish pond equation from the information given will be 
+(y -3)² = 9
<h3>How to explain the circle?</h3>
At this location, it is easy to draw a radius along the y-axis to a point of tangency at the origin. That radius is a vertical line, so the tangent line will be perpendicular to a horizontal line.
We choose a fish pond of radius 3 centered at (x, y) = (0, 3). The equation of the circle will be:
(x -0)² +(y -3)² = 3²
x² +(y -3)² = 9
On a coordinate plane, construct the circular fish pond at a given location and specify your center point and radius. Write your circular fish pond equation.
On the coordinate plane, identify the point to represent the location of the water main connection. Construct the pipe so that it is tangent to the fish pond from the water main. Include all steps to creating tangent line.
The examples of tangents in the real world are:
- When a cycle moves along a road, then the road becomes the tangent at each point when the wheels roll on it.
- When a stone is tied at one end of a string and then rotated from the other end, the stone will follow a circular path.
