One of the primary traits that appears in the phyla Bilateria is the presence of a body cavity. That is, there are three distinct layers of cells, the endoderm, mesoderm and ectoderm.
Yes, a cat's head typically exhibits bilateral symmetry, meaning that its left and right sides are mirror images of each other. This symmetry is evident in features such as the eyes, ears, and whiskers, which are generally aligned and proportionate on both sides of the head. However, natural variations can occur due to genetics or injury, which may affect the degree of symmetry. Overall, symmetry plays a role in a cat's visual appeal and functionality.
They occur across an axis of symmetry.
They occur when you divide something on a line of symmetry.
the line of symmetry would occur at x=0
The bilateral abdominocrural creases are located where the abdomen meets the thighs. They are the natural creases or folds that occur at this junction due to the different skin tension and movement in these areas.
A rectangle. Obviously the right angles are in the four corners of the rectangle. The lines of symmetry occur across the horizontal and vertical. There are no lines of symmetry on the diagonal.
Almost all cases of papilledema are bilateral (affect both eyes).
Yes, a trapezoid may have two lines of symmetry, but the trapezoid must also be a rectangle.If the trapezoid is not also a rectangle, the the most symmetry lines it can have possible is 1 (this can only occur it's an isosceles trapezoid.)
incomplete dominance
Most commonly sex linked traits are on the X chromosome, but rarely they can occur on the Y chromosome.
a dominant gene.
