A food allergy is a reaction that occurs when the <u>body</u> system reacts to a harmless substance in food, such as a protein that does not undergo digestion
Answer:
The first thing to look at would be type of symmetry the organism exhibits. If it is asymmetrical then it would be a sponge and the discovery could stop right there. If not, other characteristics need to be investigated.
Knowing the type of body cavity this organism has would be helpful.
It would also be beneficial to know what type of skeleton (endo or exo) this organism has and what its appendages look like.
Finally, the type of digestive tract and the presence or absence of a head would help to determine what this creature is.

Explanation:
When looking at a pedigree remember that:
- squares are males
- circles are females
- the solid colored figure represents an individual affected by a disease
- the empty figure represents a healthy individual
Let us assign the symbol X⁺ to represent the dominant allele linked to the X-chromosome and expressing healthiness, and X⁻ to represent the recessive allele expressing the dissease.
According to this pedigree
- I1 is a man affected by the disease, YX⁻
- I2 is a healthy woman X⁺X⁻
- we can see that among the progeny (generation II) there are two individuals affected (a boy and a girl) and one healthy girl. This means that the mother I2 is heterozygous for the trait.
So, having their genotypes we can know what are the probabilities of getting a son with DMD
Parentals) YX⁻ x X⁺X⁻
Gametes) Y X⁻ X⁺ X⁻
Punnett square)
X⁺ X⁻
X⁻ X⁺X⁻ X⁻X⁻
Y X⁺Y X⁻Y
F1)
- The probabilities of getting a healthy daughter X⁺X⁻ are 25%
- The probabilities of getting a healthy son X⁺Y are 25%
- The probabilities of getting a daughter with DMD X⁻X⁻ are 25%
- The probabilities of getting a son with DMD X⁻Y are 25%
Answer:
i. Maize seed is a monocot seed whereas bean seeds are dicot seed.
(ii) Maize seed only have a single leaf inside, most of the space inside the seed is reserved for endosperm but bean seed have two leaves, both of which store and provide food to the seedling in absence of endosperm.
(iii) Corn seeds (maize) germinates in three days but bean seed takes seven days to germinate.
Explanation:
Die is two, mono is one
