A scientist bred fruit flies in two separate containers with different food sources for many generations. When she put the fruit
flies from the two containers together again, she observed that the flies preferred mates raised on the same food. Which conclusion can the scientist draw? A. Fruit flies mate randomly regardless of how they were bred.
B. Fruit flies can adapt to eating different food sources.
C. Fruit flies prefer the container where they were bred.
D. Fruit flies prefer mates adapted to the same food source.
As per the given information in the question, initially fruit flies were in two different containers having different food sources for several generations. Due to this, they got adapted to the specific food sources to which they were exposed. As a consequence, they started preferring mates that were adapted to the same food source.
Therefore, when fruit flies from the two containers were put together, Fruit flies preferred mates adapted to the same food source.
quantitative inheritance results in a continuous range of multiple phenotypes. The final phenotype results from both gene and environmental influences. For example, human height
WHILE
Qualitative inheritance results in distinct and separate phenotypic categories. The final phenotype results from gene action. For example, fruit fly eye color.
DNA replication is a process in which the synthesis of the new strand takes place from parental DNA or strand.
DNA polymerase is an important enzyme that is responsible for the adding of the nucleotide and thus forms a new strand.
During the process of synthesis one strand is synthesized in continuous forms that goes toward the replication fork and called as a leading strand that moves in 3' to 5' direction.
The other strand that is synthesized in pieces form that is known as lagging strand and the pieces of the DNA is joined by an important enzyme known as DNA ligase.
Explanation: The sun can be used by solar panels, wind can be used by windmills, and hydroelectric energy comes from water. All of these are renewable resources.
