The genetic make-up of an organism is described as its
phenotype
genotype
character
chromosome
allele
Correct answer is B
No explanation has been provided for this answer.
A pair of genes that control a trait is described as?
dominant
recessive
allele
variant
hybrid
Correct answer is C
Alleles are different forms of the same gene that are located on the same part of the chromosome.
Alleles contribute to the organism's phenotype (the outward appearance of the organism).
0.02N
0.08N
0.20N
0.80N
1N
Correct answer is D
Upthrust = weight of the water displaced =pvg= 1000 x 2 x \(10^{-5}\)=0.20N \\ Apparent weight = weight in air – upthrust = 1-0.2N=0.8N
\(2.5\times10^{-7}\)m
\(3.8\times10^{-7}\)m
\(4.6\times10^{-7}\)m
\(5.2\times10^{-7}\)m
\(6.1\times10^{-7}\)m
Correct answer is B
n =\(\frac{wavelength\, in\, air}{wavelength\, in \,medium}= \frac{5.9\times10^{-7}}{1.54}= 3.8\times10^{-7}\)m
2.5 minutes
5.7 minutes
6.7 minutes
7.5 minutes
9.5 minutes
Correct answer is C
t = \(\frac{mc\theta}{p}= \frac{2\times4200\times50}{210\times5} \\ = 400s = 6.7\)
