Answer:
Explanation:crystal size in igneous rocks is determined by how quickly magma or lava cooled to form it.
The answer is; the melanin in darkly pigmented skin protects DNA from UV radiation, and UV radiation can cause skin cancer
In Africa, due to its equatorial latitude location, receives direct sunlight at more or less 90 degrees most of the year. These highly concentrated rays increase the UV radiation exposure that can cause damage to cell DNA. Selection pressure, therefore, favored individuals with high melanin concentrations that protect against UV. Therefore population evolved towards high melanin densities in the skin.
Genes is found in the DNA. It decides a specific characteristic. Genes can transform and take two or more option structures and these structures are called Alleles. Presently allele happens in an altered spot in a chromosome and in people we have two arrangements of chromosomes.
There are 46 chromosomes in the human. 23 from the dad, 23 from the mother = 46 chromosomes.
The complete question is as follows:
If a researcher only wanted to examine the relationship between exercise and grade point average, _________ would be used to test the variables.
A. correlation analysis
B. regression
C. hypothesis
D. central tendency measures
Answer:
The correct answer would be - A. correlation analysis.
Explanation:
To find the relationship between two variables the correlation analysis is the statistical method is used. It is used to find the what and how the one variable is related to the other variable in this method.
It is used to evaluate the relationship between any two quantitative variables.To examine the relationship between exercise and grade point average,b this method would be best as it also shows how strong is the relationship of variables.
