In this experiment, researchers compared how fast the junco populations adapted.
<h3>What is the focus of the study?</h3>
This study focuses on the adaption process of Juncos (a specific bird population) in urban environments and how they behave in terms of stress and boldness behavior (interest in exploring unknown areas).
<h3>How did the study work?</h3>
In this study, scientists compared the behavior of a population of birds in an urban area with the behavior of another population of birds that lived in a novel urban area to determine the adaptation process of the second population.
Note: This question is incomplete because the information about the study is missing; here is the name of the possible study: Boldness behavior and stress physiology in a novel urban environment suggest rapid correlated evolutionary adaptation

Answer:
The correct option is D. Crossing over and independent assortment are the causes of genetic variation.
Explanation:
In the process of meiosis, crossing over is a phenomenon through which exchange of genetic segments takes place among the homologous chromosomes.
The process of independent assortment describes how different genes assort differently during meiosis.
Both the process of crossing over and independent assortment are the basis of the genetic variations seen in the world.
Answer: The correct answer is- C. to neutralize the acidic chyme
Bicarbonate is secreted by pancreas and released into the duodenum ( first part of small intestine) during the process of digestion.
The digestive enzymes that are secreted by the pancreas ( such as protease, amylase, lipase) into the small intestine, require an alkaline pH for their optimum functioning.
Since the chyme ( partly digested food with acidic pH, coming from the stomach) is acidic in nature, thus, the release of bicarbonate and water by the pancreas helps in neutralizing it.
This aids the final process of digestion in small intestine.
