Albinism is a recessive trait. A man and woman who both have normal pigmentation have one child out of three who has albinism (without melanin pigmentation). The genotypes of this child's parents: (C) Both parents must be heterozygous.
Albinism is an autosomal and not a sex-linked recessive trait.
Only homozygous recessive (aa) offspring will be albino, both homozygous dominant (AA) and heterozygous dominant (Aa) offspring will possess the normal phenotype.
Since it is given that both the father and the mother have normal pigmentation, thus they must both have the genotype Aa.
From the Punnett square it can be observed that a cross between the parents would result in the creation of three offspring with the normal genotype (one with AA and two with Aa) and one offspring with the genotype aa (albino).

Answer:
1.) the nervous system outside the brain and spinal cord.
2.) the somatic nervous system and the autonomic nervous system.
3.) The somatic nervous system has sensory and motor pathways, whereas the autonomic nervous system only has motor pathways. The autonomic nervous system controls internal organs and glands, while the somatic nervous system controls muscles and movement. Both, receives input from sensory neurons.
Explanation:
The fertilized ovule becomes the seed, and the ovary becomes the fruit.
Hope this helped :)
More information is required to completely answer the question. Based on the experiment, feeding one group wood only and the other wood and antibiotics, the conclusion to be drawn is that the bacteria that lives in the gut of termites does not aid in digestion of the cellulose in wood.
Antibiotics only affect bacteria and so would leave the protozoa and the archaea in the gut of the termites. Both groups received the same amount of energy at the end of the experiment so it means that digestion is aided by either the protozoa or archaea and not bacteria.
