Principle of Dominance was given by Sir Gregor Johann Mendel.
<h3><u>Explanation:</u></h3>
Principle of Dominance was given by Sir Gregor Johann Mendel as a conclusion of the monohybrid cross between the different characteristic pea plants. It says that in an organism which is heterozygous for a particular character, only the dominant trait is able to express as a phenotype, not the recessive one. In other words, the recessive allele is completely masked by the presence of the dominant allele. This leads to same phenotype of a homozygous dominant organism and a heterozygous organism.
To test the organism about its heterozygosity, the organism is led through a test cross where the organism is crossed with a recessive organism. If the F1 offsprings are all dominant, then the organism is homozygous dominant, and if the F1 offsprings are of half dominant and half recessive phenotype, then the organism is heterozygous.
Answer:
As objects move around over time, the energy associated with them—e.g., kinetic, gravitational potential, heat—might change forms, but if energy is conserved, then the total will remain the same. Conservation of energy applies only to isolated systems.
Explanation:
Answer:
Chimneys are ventilation channels that guide smoke and other gases that are products of combustion out from a fireplace through the roof of a building. ... The warm air can then leave the house through the chimney through the same process of rising that hot smoke does when wood is being burned.
Explanation:
Long bones have a tubular shaft and articular surface at each end. The major bones of the arms and the legs are all long bones.
Short bones also have a tubular shaft and articular surfaces at each end but are much smaller. The short bones include all of the metacarpals and phalanges in the hands, the metatarsals and phalanges in the feet, and the clavicle.
Flat bones are thin and have broad surfaces. The flat bones include the scapula, the ribs, and the sternum.
<span>Irregular bones are irregular in size and shape and are usually quite compact. They include the bones in the vertebral column, the carpal bones in the hands, tarsal bones in the feet, and the patella.</span>
