The correct scientific name for Organism 1 is <em>Phoebis philea</em>.
<u>Explanation:</u>
The species of butterfly scientifically named as <em>Phoebis philea </em>and commonly named as orange-barred sulfur, basically found in Americas. Its scientific classification involve following points: Kingdom is Animalia; Phylum is Arthropoda; Class is Insecta; Order is Lepidoptera; Family is Pieridae; Genus is Phoebis and Species is P. philea.
The environment of this species is in tropical scrub, parks, fields and edges of the forest. The creature takes nectar from plants of red colour. The larvae depend on the species Cassia. Wingspan is between 68 and 80 mm. In Florida there are 2-3 generations a year, and one in the northern region of the range with winged adults from mid to late summer.
Answer:
25%
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⁻

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%
In recent molecular genetic studies, genes associated with the neurotransmitter Dopamine have been linked to ADHD.
ADHD stands for Attention Deficit Hyperactivity Disorder. People with ADHD have a hard time focusing on tasks. Scientists have found that the low levels of dopamine in the brain are associated with the symptoms of ADHD. It is because the neurons in the brain have a high amount of protein called the dopamine transporters. These proteins block the dopamine from passing between the neurons. This decreases the effect of dopamine.
