Answer:
Answer is D "Genes for the two traits are located close together on the same chromosome, and crossing over occurred between the two gene loci"
Explanation:
Traits are distinguishing characteristics of an organism. The Phenotypic crossing of the Drosophila melanogaster specie with Gray body and long wings over that of the same specie but female with black body and apterous wings produced a total of 100 offspring, which showed a that genetic crossing were done on the closely related chromosomes of the body traits for the individual species.

Blue winged warblers are the popular species having distinct Buzz Buzz sounds. They are most likely to live in bushy fields and known as worm eater. Their favorite food is insects and spiders.
As the springs arrives, it will affect the blue winged warbles in a very positive way. They will be more likely to reproduce in spring. They will also find more food and shelter in spring.
The correct answer is option (A) leaves > deer > wolf.
A food chain is a linear sequence of organisms through which the nutrients and energy flow as one organisms feeds on the other. They show organisms starting from the producers and end with consumers or sometimes with detrivores or decomposers. Each level of the food chain is called the trophic level. The producers which use solar energy and prepare their food occupy the first trophic level, followed by the primary, secondary, tertiary, quaternary consumers occupying the next trophic level.
In the food chain given above, leaves > deer > wolf, deers feed on the leaves which are maximum in number comparitively, wolf feeds on the deer which are comparitively more in number than the wolves. This is the correct sequence of food chain showing the tranfer of energy and decreasing number of organisms with subsequent increase in the trophic levels.
