1) recessive allele is b
dominant allele is B
When an X chromosome contains the dominant allele,is written as:
![X^B](https://tex.z-dn.net/?f=X%5EB)

2) the genotype of the woman is
She is not color-blind but she is a carrier of red-green color blindness, who passed the allele to their sons.
Woman, have two X chromosomes. If she is not colorblind is because there is the dominant allele making her see normally. But, she is a carrier, so while one X chromosomes has the dominant allele, the other has the recessive (making her carry the disease).

Answer:
SA Node
Inter-nodal Pathways
AV Node
AV Bundle
Bundle Branches
Purkinje Fibers
The SA nodes functions first for setting pace for the heart, then the inter-nodal pathway make link b/w SA and AV node. AV node is site of delay when contraction of atria occurs. AV bundle is the mean of electrical link b/w atria and ventricle. The conveying of impulse to the inter-ventricular septum occurs through bundle branches, while conveying of impulse throughout and along the walls of ventricle occurs through Purkinje fibers.
Carbon dioxide is emitted as a by-product of clinker production an intermediate product in cement manufacture, in which calcium carbonate (CaCO3) is calcinated and converted to lime (CaO), the primary component of cement. CO2 is also emitted during cement production by fossil fuel combustion.
