Each period within the time scale is different as it represents a unique slice of Earth's history, with different changes in the planet's environment, climate, and life forms.

The Geologic Time Scale is divided into several eons, eras, periods, and epochs, each representing a specific interval of time characterized by distinct changes in the Earth's environment, climate, and life forms.

The largest division of the Geologic Time Scale is the eon. There are two eons: the Precambrian and the Phanerozoic. The Precambrian eon covers the majority of Earth's history, from the formation of the planet about 4.6 billion years ago to the beginning of the Cambrian period about 541 million years ago. The Phanerozoic eon began with the Cambrian period and continues to the present day.

In conclusion, each eon is divided into eras, which are further divided into periods.

The formation of proteins by using information contained in DNA and carried by mRNA to ribosomes. Messenger RNA or mRNA copies the DNA codes in the nucleus in a process called transcription and carries the information to the ribosomes in the cytoplasm.

Ribosomes are the place for the cell to make proteins. Cells that have a high rate of protein synthesis typically have a large number of ribosomes. For example, liver cells in humans are known to have millions of ribosomes. Cells that are actively carrying out protein synthesis will also automatically have nucleoli that are clearly visible.

ribosomes have a small size and a solid round shape. These organelles can be found in eukaryotic cells or prokaryotic cells. In eukaryotic cells, some ribosomes are free and some are bound to the endoplasmic reticulum membrane.

The function of ribosomes in plant cells and other living things is to make proteins and carry out protein synthesis in cells. Cells need to be produced in order to speed up biological processes. Protein is an important part of the body's organs. In the human body, for example, the function of protein is needed to maintain tissues, speed up chemical reactions, maintain body immunity, and form body structures.

Ribosomes build proteins in two cytoplasmic locations. Free ribosomes suspended in the cytosol. While bound ribosomes are placed outside the membrane network or what is called the endoplasmic reticulum. Most of the proteins made by free ribosomes later function in the cytosol.

For example, enzymes that catalyze metabolic processes in the cytosol. Meanwhile, bound ribosomes generally make proteins to be inserted into the membrane, to be wrapped in organelles, or to be sent outside the cell.

Scatterplots represent the relationship between two variables and how correlated they are. Outliers are also identified in these plots. A) Triangles represent how the percentage of individuals expressing symptoms increase as the percentage of positive individuals increases. B) r = 0.85 is a high positive correlation. C) Outliers are atypical values that might cause misinterpretation of results.

A scatterplot is a graphic tool that represents the existing relationship between two variables. It turns out to be an easy and fast way to interpret data.

To make the representation we use a cartesian graph and by looking at the intersection points between dependent and independent variable, we can analyze what type of relationship there is. The pattern of points intersection can show the relationship between the two variables.

- High positive correlation ⇒ points are too close to each other

- Low positive correlation ⇒ points are separated from each other

- High negative correlation ⇒ points are too close to each other

- Low negative correlation ⇒ points are separated from each other

By looking at these intersection patterns, we can also identify the outliers, which are atypical and abnormal values that differ significantly from the whole data set. This value is not consistent with the rest of the observations.

Outliers suggest something went wrong while sampling or something unusual is involved. Usually, these values are eliminated from the experiment to avoid misinterpretations.

In the exposed chart,

A) Triangles represent the relationship between the variables percentage of people in the sample who tested positive and the percentage of people in the sample who experienced symptoms. This is, how the percentage of individuals expressing symptoms increase as the positive individuals increases.

B) r = 0.85 is a high positive correlation. As we can see on the chart, all empty triangles are very close to the straight line and to each other. This is a high correlation.

C) Outliers are atypical values significantly distant from the other values. They suggest a researcher's mistake or something strange in the sampled individual. These values do not represent most of the population, and if including them in the analysis, they might lead to misinterpretations of the results.

Calvin cycle, also known as the dark reaction, is a series of biochemical reactions that occur in the stroma of chloroplasts in photosynthetic organisms.

The cycle is named after Melvin Calvin, who received the Nobel Prize in Chemistry in 1961 for his research on photosynthesis. The Calvin cycle involves the fixation of carbon dioxide into organic compounds and is a key part of the process of photosynthesis.

The Calvin cycle is outlined in the accompanying diagram. The cycle starts with the fixation of carbon dioxide (CO2) by an enzyme called Rubisco, which uses energy from ATP and NADPH to produce a six-carbon sugar called glucose-6-phosphate (G6P).

This sugar is then converted to other organic molecules such as fructose-6-phosphate (F6P), glyceraldehyde-3-phosphate (G3P), phosphoglycerate (PGA), and triosephosphate (TP). These molecules are then used to synthesize other organic molecules, such as glucose, sucrose, and amino acids. The cycle is completed when the products are released from the chloroplast and used in other cellular processes.
