Answer: a.myoglobin
Explanation:
Myoglobin (Mb) and Hemoglobin (Hb) are heme proteins and are part of the family of globular proteins. These proteins are characterized by having the spherical or globular wrapped polypeptide chain having various types of secondary structures. Myoglobin is an extremely compact protein found in muscular cells of vertebrate animals, having as their main function the storage and it also facilitates the transport of oxygen in the muscles. This protein is found in the cardiac muscle and skeletal muscle of the mammals and increases the effective solubility of oxygen in the muscle by acting as an oxygen reservoir and facilitating the diffusion of O2 from the capillaries blood to the mitochondria.
Answer:
Probability of having a child with this genotype: CcFf is 
Explanation:
Given -
Curly hair (C) is dominant to straight hair (c)
and
Freckles (F) is dominant to not having freckles (f)
Genotype of man heterozygous for curly hair and no freckles is Ccff
Genotype of woman with straight hair and heterozygous condition for freckles is ccFf
The cross is between Ccff and ccFf
The following offspring would be produced
Ccff and ccFf
Cf Cf cf cf
cF CcFf CcFf ccFf ccFf
cF CcFf CcFf ccFf ccFf
cf Ccff Ccff ccff ccff
cf Ccff Ccff ccff ccff
Genotype –
CcFf – 4 in number
ccFf - 4 in number
Ccff - 4 in number
ccff - 4 in number
Phenotype
CcFf – heterozygous for both the curly hairs and freckles
ccFf – straight hairs with heterozygous freckle condition
Ccff – Heterozygous curly hair with no freckles
ccff – staright hairs with no freckels
probability of having a child with this genotype: CcFf is
