D
B makes no sense
C makes so sense as variation causes natural selection so if they were all the same natural selection wouldnt happen
A isnt right
the answer is D as the organisms must have some variation in order to be different enough and less/more well adapted to their habitat in order for the less well adapted ones to die- and the more well adapted ones to live and pass on advantageous alleles/genes
Neurotoxin !!!!!!!!!!!!!!!
Answer:
C.
Explanation:
The chemical RuBP, is not even mentioned in that cycle, making it the least viable answer.
Basically it has chemicals that break down its food and it poops the left overs out
Answer:
0.0177
Explanation:
Cystic fibrosis is an autosomal recessive disease, thereby an individual must have both copies of the CFTR mutant alleles to have this disease. The Hardy-Weinberg equilibrium states that p² + 2pq + q² = 1, where p² represents the frequency of the homo-zygous dominant genotype (normal phenotype), q² represents the frequency of the homo-zygous recessive genotype (cystic fibrosis phenotype), and 2pq represents the frequency of the heterozygous genotype (individuals that carry one copy of the CFTR mutant allele). Moreover, under Hardy-Weinberg equilibrium, the sum of the dominant 'p' allele frequency and the recessive 'q' allele frequency is equal to 1. In this case, we can observe that the frequency of the homo-zygous recessive condition for cystic fibrosis (q²) is 1/3200. In consequence, the frequency of the recessive allele for cystic fibrosis can be calculated as follows:
1/3200 = q² (have two CFTR mutant alleles) >>
q = √ (1/3200) = 1/56.57 >>
- Frequency of the CFTR allele q = 1/56.57 = 0.0177
- Frequency of the dominant 'normal' allele p = 1 - q = 1 - 0.0177 = 0.9823
