Using the nonexperimental method, a researcher collects data on exercise and anxiety from a number of people and finds that exer

cise is negatively related to anxiety—that is, the people who exercise more tend to have lower levels of anxiety. What does this scenario demonstrate?

Answer:

Co-variation between variables

Explanation:

Based on the scenario being described within the question it can be said that this scenario demonstrates the Co-variation between variables. This refers to the measure of how much two seemingly random variables vary together as opposed to separately which would otherwise be variance. Which explains why when one variable changes in value the other changes in an un-correlated way.

Answer:

Co-variation between variables.

Explanation:

Co-variance refers to measurement of the relationship between two random variables. That is  how the two variables change proportionately, or  varies  with one another. However, it does not explain how the two variable depends on one another.

Thus when the two variables moves in the same direction with one another, it is called positive co variance. However, when they move in inverse proportion to  one another, they are negative co-variance.(as represented in the question).

Thus it shows how exercise and anxiety varies with one other, but it does not show how  they depend on one another.

Cells are often ground up with abrasive to get to their internal enzymes/molecules, followed by removal of the abrasives. Here a
AlladinOne [14]

Answer:

Option (1).

Explanation:

The RNA is produced from the DNA by the process known as translation. The proteins products are produced from the RNA by the process known as translation. Proteins are the polymers of the amino acids.

The situation 1, radioactive amino acids has been used. In this case, the mRNA is used in this process to make the radioactive proteins by the process of translation. The radioactive amino acids are used for the formation of radioactive protein. The situation 2, the RNAase has used with radioactive amino acids. In this case, the RNAse enzyme breaks the mRNA molecule and the proteins are not translated that contains the radioactive amino acids. No proteins formation occurs in this case.

Thus, the correct answer is option (1).

What Is Chemogeny ( Chemical Evolution ) ? And Explain The Steps Of Chemogeny [Both Answer In Simple Word/ Simple Answer Which I
solniwko [45]

Answer:

Chemogeny may be a theory of chemical evolution that depends on the chemical reactions and formation of drugs on the bases of chemical reactions. This theory says that “Life occurs as a results of evolution of inorganic matter”.

In the 1920's Scientists Oparin and Haldane, developed this hypothesis of the chemical origin of life from the primitive atmosphere of the world having matter like methane, ammonia and water. there have been very low concentrations of oxygen thanks to the presence of high temperatures like 5000-60000C. So, these conditions weren't suitable for the free existence of organic compounds, so reactions started happening .

Under conditions like high sunlight and warmth , inorganic matter gets converted to inorganic compounds. And this might end in the storage of organic compounds, which gets more and more concentrated with the passage of many years.

These compounds interact with one another and end in “life”.

So, chemogeny is that the process of chemical evolution of earth and formation of life from pre-existing matter with the assistance of chemical reactions.

Explanation:

Hopefully I was able to help you with the concept. Good luck!
