The rigth answer is D.

The wavefront or wavefront is an equal phase surface of a wave, i.e., these points have the same travel time from the source. The concept is used to describe the propagation of waves such as sound or electromagnetic radiation (light, radio waves, etc.). In a homogeneous and isotropic medium, in which the waves propagate without deformation, two types of particular waves are distinguished according to whether the wavefronts are spheres (spherical wave) or planes (plane wave).

D.perceptual constancy

The CORRECT ANSWER IS D.

D.perceptual constancy

Explanation:

Perceptual constancy, is also know as Object Constancy, or Constancy Phenomenon. It is the ability of the brain to view perception of objects not minding the variations in retinal image when an object adjusts position or distance from the viewer. It helps animals and humans to view familiar objects as possessing standard shape, size, colour, or location irrespective of variations in the angle of perspective, distance, or lighting despite the fact that the illumination and retinal images may vary.

Another example is the distance between a door and an individual such that no matter the distance between a door and a person, the person still perceive it as possessing a constant size.

Andrei [34K]

Answer:

Seeds- form through <u><em>sexual </em></u>reproduction and contain an embryo that gives rise to a new plant.

Explanation:

The formation of seeds occur when a ripened ovule is fertilized by pollen. If the pollen and the ovule are from the same plant, then it is termed as self-pollination. If the pollen fertilizes the ovule of another plant then it is known as cross pollination. The seed contains the embryo which has the capability to form and generate into a new plant. Hence, the formation of seeds is a phenomenon which occurs in sexually reproducing plants.

scZoUnD [109]

Answer:

Al children would have a Tall head shape

Explanation:

Patrick is purebred for the dominant tall head shape so his genotype would be TT. Patti on the other hand is short headed, which is recessive, so the only possible genotype would be tt. If we put that in a Punnet, you can see the result:

TT x tt

T T

t Tt Tt

Since all the results are Tt, that means the tall head shape would be expressed because it is dominant and it will mask the recessive trait. So the answer would be:

All children would have a tall head shape.
