A light year is used for measuring distance.
Answer:
C: They all have some mutation in some wing-development gene. Each strain may have a different mutation in a different gene, but all strains within a complementation group have the same phenotype.
Explanation:
From the situation of the question given, we can say that the true statement about flies that belong to different complementation groups is option C primarily because Strains existing in different complementation groups obviously would have mutations in different genes.
Herbicides are not a type of biological contamination since they are toxic substances that are not living things.
The given statement is True.
The transport process that does not requires the consumption of ATP molecules is called as passive transport. The movement of solute molecules along the concentration gradient (from higher concentration to lower concentration) is called diffusion. This process does not requires ATP for the movement of molecules from one place to another.
