When the left ventricle contracts, it forces blood through the aortic semilunar valve and into the aorta. The aorta and its branches carries the blood to all the body's tissues.
WHAT IS AORTAAorta is the largest artery that carries blood and oxygen from the heart throughout the body. The structure of the aorta begins at the aortic valve which separates the aorta from the left ventricle of the heart. The left ventricle is the last chamber through which blood flows towards the heart.
Just above the aortic valve, there are two branches known as the left main coronary and the right main coronary. These two branches of the aorta are responsible for transporting blood to the heart muscle. From the aortic valve, the aorta moves upward, extending around the second rib.
This section is known as the ascending aorta. Then, the aorta curves down and to the left. This part is called the aortic arch. From here, the aorta runs down the body to a final section called the descending aorta.
FUNCTION OF AORTAAorta is very important for the human body because it is the main blood vessel that supplies oxygenated blood to all tissues and organs of the body to keep them functioning properly.
So, if there is a problem with the aorta, such as a blockage, structural anomaly, or rupture, it can harm other organs of the body. Problems with the aorta can be triggered by uncontrolled high blood pressure and cholesterol.
Thus, several ways can be done to maintain the health and function of the aorta, such as consuming a balanced nutritional diet, doing physical activity, stopping smoking, and regularly seeing a doctor to monitor your blood pressure and cholesterol.

Explanation:
The scatterplot shows data collected by the CDC (Centers for Disease Control and Prevention) about influenza, a flu virus.
a) Describe what the triangles in the scatterplot represent. (2 points)
b) The correlation coefficient for all of the data (r) was calculated as 0.85. What type of correlation does this show? Explain. (2 points)
c) The dark triangles in the graph are outliers. What are outliers, and how do they affect data?
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.
What is the scatterplot?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.
Directly proportional relationship ⇒ while one of the variable values increases, the other variable values increase as well.- High positive correlation ⇒ points are too close to each other
- Low positive correlation ⇒ points are separated from each other
Inversely proportional relationship ⇒ as one of the values of the variables increases the values of other variable decreases.- High negative correlation ⇒ points are too close to each other
- Low negative correlation ⇒ points are separated from each other
No relationship ⇒ There is no tendency in the dispersion of the points. There is a homogeneous cloud. No correlation can be established between variables.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.

What is the formation of proteins by using information contained in DNA and carried by mRNA?
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.
What Are RibosomesRibosomes 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.
Functions of RibosomesThe 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.

What is Calvin cycle is explain it with the help of diagram?
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.

If the time between the capture and the recapture is too long and some of the marked animals die and also new animals are born so that the population size remains constant, then the death of the marked animals will tend to make the estimate of the population size too large because at a specific time marked animals will represent born and dead animals, thereby overestimating population size.
Why is important to have short periods of capture in population estimation?It is fundamental to have short times during the capture and recapture of animals during population estimation because too long periods may lead to overestimating the size of a population having constant size.
