Fruit flies produce offspring relatively fast and have specific traits, such as eye color and body color/shape. They are easy to observe and their traits are easily traced throughout the next generations.
Answer:
Random mutations led to evolution of pesticide resistance genes in bed bugs.
Explanation:
Random mutations in genome of bed bug imparted them the pesticide resistance. Since the bed bugs having the mutation of pesticide resistance were able to survive under presence of pesticides, this variation was favored by natural selection. The bugs with pesticide resistance transmitted this trait to their progeny. In time, the bed bug population consisted of most of the bugs having the pesticide resistance.
Answer:
Chromosomes can exchange genetic information during a process called "crossing over." This occurs when homologous chromosomes are lined up in pairs. This recombination of maternal and paternal genetic material is a key feature of meiosis.

Through "cellular respiration" process energy is stored in the form of glucose.
<u>Answer:</u> Option A
<u>Explanation:</u>
The series of metabolic reactions and mechanism take place in organism ranging from microscopic bacteria to large organisms cells in order to transfer biochemical energy from food nutrients (stored in glucose form which is transferred) to adenosine triphosphate (ATP) and then waste product is also released, the whole process is known as "cellular respiration".
The energy required for ATP synthesis extracted from the breakdown of foods and phosphocreatine (creatine phosphate). It is stored inside muscle cells because phosphocreatine is readily available to produce ATP quickly.
