It's not cilia because cilia found in nearly all the cells in the body.
It's not mitochondria; those are found in liver cells and others.
It's not lysosomes because those function as the digestive system in the cell.
That means the answer is flagella
Sperm are the only human cells to have flagella.
The correct answer is A. Flower color is a recessive trait.
The recessive gene does not show its effect in heterozygous condition according to Mendel’s law of dominance. Thus, in heterozygous condition, dominant gene determines the phenotype for a trait. In this question a plant is homozygous for flower color. This indicates that pink flower determining gene can only be expressed in homozygous condition. Therefore, flower color is a recessive trait.
I could be wrong here but I think factories and animals are 2 ways carbon gets into the air because animals breath out carbon, while factories pollute the air with carbon. If anything I would think plants are responsible for removing it because they give out oxygen.
