Answer: The man's genotype is WwLt while the woman's genotype is wwLt.
Explanation: From the information given above, W is the allele for wide jaw, w is the allele for narrow jaw, W is completely dominant to w, L is the allele for large teeth while t is the allele for small teeth.
The man has wide jaw but his mother has a narrow jaw, since narrow jaw is recessive the man must have inherited one recessive allele for narrow jaw from his mother who has two recessive alleles for narrow jaw. Therefore since the man has wide jaw, he must be heterozygous for wide jaw (having one dominant allele for wide jaw and one recessive allele for narrow jaw), his genotype for wide jaw is therefore Ww. The man is heterozygous for teeth size, this means that he has one dominant allele for large teeth and one recessive allele for small teeth. His genotype for teeth size is Lt. Therefore the man's genotype is WwLt.
The woman has a narrow jaw, this means that she has two recessive alleles for narrow jaw (ww) and she is heterozygous for large teeth size, this means that she has one dominant allele for large teeth and one recessive allele for small teeth (Lt). Therefore, the woman's genotype is wwLt.
Answer: Flatworms, Roundworms and Segmented worms
Explanation:
These are not all placed in a phyla because the degree of developmental and morphological similarity is low.
The flatworms also known as platyhelminthes do not have coelom, no respiratory system or a circulatory system. An example is the tapeworm.
The roundworms also known as nematodes are slightly more complex than the flatworms in that they have a pseudocoelom and they are bilaterally symmetrical. An example is Ascaris lumbricoides.
The segmented worms are the most complex of them in that they have a true coelom, a circulatory system found in each segment and a digestive system. An example is the earthworm.
A response to exposure would mean that your body is reacting to the harmful chemical. when your health is at stake, your body reacts with a response. for example, if you get a chemical in your eye, you start tearing up and your eye turns red. that's a response to the chemical.
