Answer:
I think true statement is A.
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!
The law of conservation of mass states that the mass will stay constant given a chemical reaction because no atoms were created or destroyed. This being said, an example can include water evaporating in a clear bottle outside on a hot day ( the mass of the bottle will stay the same, but the liquid water evaporated into gaseous water).
The correct answer is a - cerebrum
The cerebrum, also called cortex is the largest part of the brain. It is divided into four sections, called lobes and these are the frontal lobe, the parietal lobe, occipital lobe and temporal lobe.
Front lobe helps in speech, reasoning, planning, movement , emotions and problem solving.
parietal lobe helps in orientation, and perception of stimuli and movement.
Occipital lobe helps in visual processing.
Temporal lobe helps in memory, speech as well as perception and recognition of auditory stimuli.
