Answer: Option 'a' is correct.

Explanation:

Researchers can isolate a single factor and examine the effect of that factor alone on a particular behavior through use of a choices is an experiment.

As experiment means when a hypothesis is tested scientifically and check when the cause is changed what would effect that factor alone.

whereas correlational study is the study of two variables understand it and develop the statistical relationship between them without affecting from any variable.

Hence, option 'a' is correct.

A common method of estimating how far a lightning flash is from you is to count the seconds between the flash and the thunder, a
ella [17]

Answer:

FLASH TO BANG RULE.

Explanation:

The “Flash-To-Bang” theory measures the time from when you see lightning to the time you hear the associated thunder. A measure of 5 seconds from Flash-To-Bang means lightning is one mile (1.6km) away. Ten seconds equals 2 miles (3.2km); 15 seconds equals 3 miles(4.8km).

Light travels faster than sound, so lightning will be seen before hearing it (the thunder is the sound of the lightning strike).

The speed of sound travels at around 340m/s, multiplied by 3 is about 1kilometer. So the number of seconds divided by 3 is how many kilometers away the lightning struck is.

The number of miles away a thunder struck is, can be calculated by dividing the seconds by 5.

An analysis of regression is used to test the significance of a linear regression equation based on a sample of n = 20 individua
Vsevolod [243]

The correct answer is option A. 1,18.

Linear regression is a method used to identify the trend Or similarity between two sets of data. All the given points of the data set are plotted and a straight line is drawn with the points. The line is called a line of regression.

F Test is a test that is used to check if the given line of regression is a good fit for the given data set or not.  F ratio is the ratio obtained by dividing the two mean square values of the data set.

The numerator of the given regression is always 1

The denominator of the regression is given by n-2=20-2=18.

How does meiosis differ from mitosis?
aniked [119]

Answer:

In cell biology, mitosis  is a part of the cell cycle in which replicated chromosomes are separated into two new nuclei. Cell division gives rise to genetically identical cells in which the total number of chromosomes is maintained. Therefore, mitosis is also known as equational division. In general, mitosis is preceded by S phase of interphase (during which DNA replication occurs) and is often followed by telophase and cytokinesis; which divides the cytoplasm, organelles and cell membrane of one cell into two new cells containing roughly equal shares of these cellular components. The different stages of mitosis altogether define the mitotic (M) phase of an animal cell cycle—the division of the mother cell into two daughter cells genetically identical to each other.
