Answer:
I used the names George Clooney and Tim Allen to remember the pairs of nitrogenous bases in DNA.
Explanation:
DNA is composed of nucleotides, however the nucleotides are formed by nitrogenous bases called Adenine, Guanine, Cytosine and Thymine. Each nucleotide has a nitrogenous base, but these bases form pairs, allowing the nucleotides to come together. The pairs are formed solely by Timine and Adenine or Guanine and Cytosine.
As I needed to remember the formation of the pairs to do my biology test, I associated the first letter of each base, with the initials of two famous names.
As Guanina is paired with Cytosine (G-C), I associated this pair with the initial letters of the name George Clooney. As Timina is paired with Adenina (T-A), I associated this pair with the initials of the name Tim Allen.
Answer:
<em>A decrease in the unemployment rate is most likely a topic of discussion in macroeconomics.</em>
Explanation:
Macroeconomics studies the economy as a whole, in a large-scale (e.g.: national or global) level. On the other hand, microeconomics studies the decisions of individuals (e.g.: people or companies).
Keeping this in mind, let's analyze the options that we're given:
- An increase in the price of a hamburger: This would be macroeconomic if, for example, the prices of all products in the economy increase as well (that wold be the inflation); but, since we're dealing with the price increase of a single product, this belongs to microeconomics.
- A decrease in the production of DVD players by a consumer electronics company: In this case, we are also talking about microeconomics since it's just one company that is decreasing its production of a very specific good. If all goods or services decreased within an economy, we would be dealing with a macroeconomic scenario.
- An increase in the wage rate paid to automobile workers: In this scenario, we are dealing with the effect of the increase of the wage rate paid to a single segment of the economy, so it's microeconomic. If we were dealing with an increase of the minimum wage, then it would affect all or most workers in an economy regardless of their sector, so it would be macroeconomic.
- A decrease in the unemployment rate: The unemployment rate measures the amount of unemployed workers out of the total workforce. This is a macroeconomic variable since it describes the aggregate of an economy, is related to other variables such as GDP, and allows us to have an idea of the structure of that economy. It doesn't tell us any information about the decisions of the individuals.
Therefore, a decrease in the unemployment rate is most likely a topic of discussion in macroeconomics.
Active listening, trouble shooting, operations analysis and writing
Answer:
Correct answer is D
Explanation:
open is a function in c++ programming language used to interact with files.The function takes two parameters as input
- File name
- mode
File Name
File name is a string name of file to be opened.This is a compulsory parameter for open method.
Mode
Mode is an optional parameter in open function.Following are the accepted values of mode parameter
Prefix ios:: is added to start of each
- in (Open file in input mode for writing data to file)
- out (Open file in output / read-only mode to read data from file)
- binary (Open file in binary format)
- ate (Set the starting point of file to the end of file. Default starting point of file is start of file)
- "trunc" (If file is opened multiple times all previous data is replaced with new data)
- app (All operations of output are performed the end of file)
Use | operator to use multiple modes at a time.
