Genetic variation is a term used to describe the variation in the DNA sequence in each of our genomes. Genetic variation is what makes us all unique, whether in terms of hair colour, skin colour or even the shape of our faces. genetic disorder is when these thing are not working properly.
Radial symmetry can be likened to a pizza or bicycle wheel, where all the parts are equal and arranged around a central axis.
An example of organism with radial simetry is the hydra if you take a central axis and planes that contain that axis both sides would be symetrical
X^H X^H, because Irene does not have the recessive gene therefor her chromosomes are both dominate showing that she does not have the recessive trait

B — to relate the type of box material to the warmth of air within the box
Explanation:
She changed the box material and measured the warmth of the air in the box.
A is wrong. The question does not mention the mass of the box.

This is actually a Physics question, but who cares, A spoiler, most commonly called a wing is to add pressure to the back of the car to keep the back tires on the road, thus causing the back tires that propel it to have more traction and grip better, Spoilers are used on Rear wheel drive cars, if you put it on a front wheel drive car it is just drag being added. Spoilers are used to enhance grip so that the driver can get to point A to B easier, also a lot of faster cars like Stock car racing and Drag racing, without it the car would go flying due to all the air under it, it would act like an airplane wing...
Short answer: Air pressure forces the back tires down to the ground more causing more friction so the car can grip better.
