The right answer is B) gene.
A gene, in genetics, is a basic unit of heredity which in principle predetermines a specific trait of the form of a living organism, as defined in 1909 by Wilhelm Johannsen. From the physical point of view, a gene is a fragment of the determined locus of a DNA sequence.
A gene "parameter" the synthesis of a given RNA, by predefining its structure and, therefore, that of the possible protein or possible polypeptide synthesized from this RNA: this is what molecular biology studies .
These two aspects of the notion of gene are supposed to correspond, one at the physical and molecular level, the other at the level of principle and heredity.
Answer:
In complete dominance, only one allele in the genotype is seen in the phenotype. In codominance, both alleles in the genotype are seen in the phenotype. In incomplete dominance, a mixture of the alleles in the genotype is seen in the phenotype.
Explanation:
Answer:
Locomotion and feeding
trapping dust
Explanation:
Paramecium is an organism that belongs to kingdom protoctista. They swim in water through beating of the cilia. They also feed on tiny organisms that are swept into the oral groove through beating of the cilia.
During gaseous exchange in mammals, along the nasal passage are cells with cilia that trap dust particles and beats to move mucus and dust trapped up to the larynx.
A. Lungs are strenghtened through cardiovascular exercise.
