Carrie conducted an experiment to see if listening to different types of music would affect a person’s pulse. Her hypothesis was that pulse rate would change with different types of music. She had 10 volunteers. Each of the first 5 volunteers listened to seven different music selections for 30 seconds each. The person’s pulse was taken before the music and after each 30-second interval of music was completed. The other 5 volunteers did not listen to music and had their pulse taken every 30 seconds for 5 minutes. Based on her experiment, Carrie concluded that a person’s pulse rate did change when the person listened to different types of music. Identify the control group, the experimental group, the independent variable, and the dependent variable.

Answers

Answer 1

Answer:

Independent variable: MUSIC

Dependent variable: PULSE

Control group: The 5 volunteers that did not listen to music.

Experimental group: The 5 volunteers that listened to seven different music selections for 30 seconds each

Explanation:

- Independent variable in an experiment is the variable that the experimenter changes or manipulates in order to bring about a measurable response. In this experiment, the independent variable is DIFFERENT TYPES OF MUSIC THAT WAS PLAYED BY CARIE.

- Dependent variable is the variable that responds to the changes made to the independent variable. It is the variable being measured in an experiment. The PULSE, which was measured in this experiment, is the DEPENDENT VARIABLE.

- Control group is the group of an experiment that does not receive the experimental treatment. In this experiment, the GROUP OF 5 VOLUNTEERS THAT DID NOT LISTEN TO ANY MUSIC is the CONTROL GROUP.

- Experimental group is the group that is subjected to the experimental treatment in an experiment. In this experiment, the GROUP OF 5 VOLUNTEERS THAT LISTENED TO SEVEN DIFFERENT TYPES OF MUSIC IS THE EXPERIMENTAL GROUP.

What if researchers followed a similar method used in this activity to calculate the correlation coefficients for the gene expression patterns of every patient with osteosarcoma and they found that all patients fell into two categories of gene expression patterns? What would this tell you about the single disease we call osteosarcoma? How might this information affect osteosarcoma cancer patient diagnosis and treatment in the future?

Answers

Answer:

- Abnormal gene expression patterns can lead to osteosarcoma

- Different signaling pathways (at least two) are involved in osteosarcoma

- Differentially expressed genes might be promising biomarkers for early detection of osteosarcoma

Explanation:

Cancer can be defined as a group of genetic diseases that are characterized by uncontrolled/inappropriate cell growth. In general, cancer pathways are associated with abnormal expression of signaling components that disrupt the regulatory networks capable of controlling cell function, thereby cancerous cells can inhibit programmed death cell (apoptosis). Osteosarcoma is one type of cancer disease that starts in the bones, i.e., this disease may be triggered by overactivity of bone cells. Additionally, it is important to note that different immune-related genes were recently found to be dysregulated in osteosarcoma. For example, differentially expressed immune-related genes involved in PI3K/AKT, MAPK and JAK-STAT signaling pathways have shown prognostic value in this disease.

Abnormal gene expression patterns can lead to osteosarcoma, different signalling pathways are involved in osteosarcoma, and differentially expressed genes might be promising biomarkers for the early detection of osteosarcoma.

What is the cause of osteosarcoma?

Most osteosarcomas are not caused by inherited gene modifications, but instead are the effect of gene changes acquired during the individual lifetime.

Sometimes these gene modifications are caused by radiation therapy used to treat another form of cancer because radiation can harm the DNA inside cells.

Thus, these are the following reasons.

In studying the environment, nature does the experiments, scientists collect the data. How does the principle of uniformitarianism help answer questions about environmental changes?

Answers

Answer:

The principle of uniformitarianism helps answer questions about environmental changes because it gives scientists the idea that the scientific conditions that exist today have always been in existence. This makes it easier to draw correlations.

Explanation:

The principle of uniformitarianism states that the natural conditions that exist today have remained unchanged through the span of human life. This helps scientists in their understanding of nature. For example, they are better able to understand the formation of the earth as well as the uniformity of law across space and time.

Uniformity of law is an aspect of the principle of uniformitarianism which states that the laws of nature are constant across time and space. Uniformity of degree states that geological conditions have remained constant over time. These principles help scientists to better understand environmental changes.

The concentration of a substance inside a cell is greater than outside the cell. What type of transport is needed to move molecules of the substance from outside the cell to inside?

Answers

Answer:

Osmosis

Explanation:

The type of transport needed to move molecules of the substance from outside the cell to inside is active transport.

What is active transport?

Active transport is the movement of molecules against a gradient or other form of resistance, for example from a lower to higher charge area.

Cells use active transport to accumulate molecules such as glucose and amino acids.

A cell must use energy to move compounds against such a concentration or electrochemical gradient.

Active transport mechanisms do exactly that, expending energy more often in the form of ATP to maintain proper ion and molecule concentrations in living cells.

In the given scenario, the concentration of substance is more inside the cell than outside and the substance has to move from outside to inside the cell. This requires energy for processing.

Thus, the given scenario can be accomplished using active transport.

A celestial object is an observable cosmic phenomenon that happens naturally. The terms "object" and "body" are frequently used synonymously in astronomy.

A celestial object, on the other hand, is a complex, less cohesively bonded structure that could include numerous bodies or even other objects with substructures, as opposed to a celestial body, which is a single, tightly bound, adjoining entity. Space objects like the Sun, planets, moons, and stars are referred to as celestial bodies or heavenly groups.

They are normally quite far away from us and are a part of the vast cosmos we inhabit. Such objects are scattered throughout the majestic night sky, and when viewed through a telescope, they reveal intriguing worlds of their own.

Therefore, Mercury, Mars, Venus, Earth, Neptune, Uranus, Saturn, and Jupiter Is smallest to largest.
