Because the three-horned alien is heterozygous, we know that three must be dominant to four, because the gene for the three horns is "hiding" the gene for four horns. Therefore, the three-horned alien has the genotype Tt (T for three horns, and t for four horns). The four horned alien must be tt, because that is the only way that a recessive trait may be seen. If you solve the punnet square on a cross between Tt and tt, you end up with half three (heterozygous) and half four (homozygous recessive) it is a bit easier to explain with something a little "closer to home" if you want me to explain it again, just say so, I don't mind!
This statement about matter is true: MATTER IS MADE UP OF ATOMS AND HAS MASS.
Matter is defined as anything that has mass and occupies space. The mass of an object is the measure of the extent to which the object can resist a change in its direction when a force is applied to it. A matter is usually made up of atoms, which is defined as the smallest component of any matter. Therefore matter is made up of atoms and it has mass.
An anatomist studies the parts of the body by looking at the physical components of the that body part and identifying its functions. A physiologist looks at the mechanism at how a body part functions. The components of the eye according to an anatomist would be based on the different physical components of the eye while to a physiologist, the components would be based on the functions.
