The evidence in the myths "The Maori:Genealogies and Origins in New Zealand" and also the "The Raven and the First Men: The beginnings of the Haida" shows about the Maori and Haida cultures are; they are similar than different because they have important values in common. This will make the correct answer A.

Hemophilia is a genetic disorder that inherited by X-linked recessive pattern. A daughter needs 2 genes to have the disease(or 1 gene to become carrier) but a son only needs to get 1 defect genes from his mother(X  gene in male must come from mother). If Xh defected gene and X normal genes, the <span>punnett square </span>would be:
                       Father(XY)
                        X         Y
Mother   Xh    XhX      XhY    ------>XhX= carrier , XhY= sick
 (Xh X)     X     XX        XY      ------>healthy
        
             
        
        
        
Answer:
The zygote simply is the fertilized ovum or egg cell or female reproductive cell. It is the result of the process of fertilization of the fusion of the male reproductive cell (gamete) and the female reproductive cell ( gamete). In human, the zygote is the resulted cell of fertilization of the sperm and the ovum. It is diploid or 2N which means it contains two sets of chromosomes; one set from the male and the other from the female.
The gamete is the reproductive cell. There are two types of gametes; male gamete and female gamete. In human, the male gamete is called the sperm and the female gamete is called the ovum. The gamete is the last stage of the reproductive cells to be completely formed.
Fertilization is the fusion of the male gamete and the female gamete to form the zygote. Fertilization may be external as in fish or internal as in human.
 
        
             
        
        
        
The correct response is,
the sequences within the promoter region at -10 and -35 are the most important for recognition by the sigma subunit.
Promoter region is the DNA sequence located upstream of the corresponding gene. Promoters for genes are essential as RNA polymerase recognizes the promoter region and binds to it forming the holoenzyme complex which can inititate transcription of the gene located downstream.
Sigma factor is the transcription factor found in bacteria, RNA polymerase has a subunit for the sigma factor, this factor only can recognise the sequences in the promoter region and bind to it thus initiating transcription. 
Promoters usually have 2 parts of conserved regions, -10 element and -35 elements. Both these regions have conserved sequences.
The sigma factor is capable of identifying these conserved sequences at these particular locations of the promoter and can bind to these sequences. 
once the sigma factor binds to these regions, RNA polymerase too binds and forms a transcription initiation complex and then transcription of the downstream gene is initiated.
Therefore promoters need not have identical sequences for the sigma factor to bind, as long as the -10 and -35 regions have conserved sequences the sigma factor can bind and transcription initiation will be followed.
