Answer:
The correct answer is option (d) "both b and c".
Explanation:
Experimental model organisms used in scientific investigations have to fulfill certain criteria in order to be useful in the laboratory. Two of the desired characteristics are being able to reproduce quickly and with enough number of offspring in order to study genetic behaviors. <em>Arabidopsis thaliana</em> characteristics of being able to reproduce in 8–10 weeks and producing thousands of offspring per plant (because it can produce thousands of seeds) makes it a model flowering plant for experimental studies.
The hare is probably the prey for the lynx so when the hare go away the lynx do also
Option B would be correct. Osmosis is the movement of water molecules from higher to lower concentration, while Diffusion is the movement of higher to lower particle concentration.

Answer and Explanation:
a) Frequencies of A and G lalleles are as follows:
f(A) =( 84+24)/174 = 0.62
f(B) = (42+24)/174 =0.38
b) Expected genotype frequencies:
f(AA) = (0.62) (0.62) = 0.384
f (AG)= 2(0.62) (0.38) =0.471
f(GG) = (0.38) (0.38) = 0.144
c) Genotype Observed Expected O-E (O-E)2 (O-E)2/E
AA 42 33 9 81 2.45
AG 24 41 17 289 7.05
GG 21 13 8 64 4.92
Chi squared = 14.42
The number of degrees of freedom is the number of genotypes minusthe number of alleles= 3-2 =1
The p value is much less than 0.05, therefore we reject the hypothesis that these genotype frequencies may be expected from HArdy Weinberg equilibrum
