Considering the definition of probability, the correct answer is third option: the approximate probability of a moth being brown and yellow respectively is 33% and 21%
Probability is the greater or lesser possibility of a certain event occurring.
In other words, probability establishes a relationship between the number of favorable events and the total number of possible events.
Then, the probability of any event A is defined as the quotient between the number of favorable cases (number of cases in which event A may or may not occur) and the total number of possible cases. This is called Laplace's Law.
In this case, you know that in a moth population, 48 are brown, 30 are yellow, and 67 are black. So, the total number of possible cases is calculated as:
total number of possible cases= 48 + 30 + 67= 145
The number of favorable cases for a moth to be brown is: 48
Then the probability that a moth is brown is calculated as:
= 0.33= 33%
On the other side, the number of favorable cases for a moth to be yellow is: 30
Then the probability that a moth is yellow is calculated as:
= 0.21= 21%
In summary, the correct answer is third option: the approximate probability of a moth being brown and yellow respectively is 33% and 21%

Answer:
Dihybrid cross: Cp cp W w x Cp cp W w
Gametes= CpW; Cpw; cpW; cpw
Cp Cp: lethal phenotype
Genotypes:
Cp cp W w >> creeper and white phenotype
Cp cp w w >> creeper and yellow phenotype
Cp cp W W >> creeper and white phenotype
cp cp W W >> normal (non-creeper) and white phenotype
cp cp W w >> normal (non-creeper) and white phenotype
cp cp w w >> normal (non-creeper) and yellow phenotype
Since it is a dihybrid cross that involves a lethal allele in homozygous condition (Cp), it is expected a phenotype ratio of 6:3:2:1, it is 6 (Cpcp W_ creeper white) : 3 (cpcp W_ normal white ) : 2 (Cpcp W_ creeper yellow) : 1 (cpcp ww normal yellow). This ratio is expected because it is a distortion from normal segregation proportions (i.e., instead of the 9:3:3:1 phenotypic ratio associated with dihybrid crosses).

Tissues because tissue is made out of celss
Answer:
The correct answer is :
Independent variable: study music.
Dependent variable: test performance.
Explanation:
Independent variable in a experiment is a variable or a factor that is manipulated or changed in a particular experiment to see its the effect on dependent variable of this change. In this case classical music is variable as it is manipulated to see if it has any effect on studying.
Dependent variable is a variable which is measured in experiment to find the result and affected by the independent variable. In this case testing the performance of subject is dependent variable as it is being measured and affected by classical music.
Thus, the correct answer is: Independent variable: study music.
Dependent variable: test performance.
C. find the wind speed and direction
