Answer:
E) founder effect and genetic drift
Explanation:
Dunkers moved to Pennsylvania and inhabited a new area to develop a new population. This new population might not have the same gene pool and the same allele frequencies for all the genes as present in the original population. The change in the allele frequencies of a population due to the colonization of a new area by a few members is called the founder effect.
The small size of the new population of Dunkers present in Pennsylvania was more likely to be affected by any chance event which could have added more uniqueness to their gene pool. This is called genetic drift. Therefore, the genetic uniqueness of their population from all the other populations and from their original population might be the result of founder effect and genetic drift.
Answer:
- Lumen of duodenum will be acidic as compard to normal environment of the lumen of abdomen when processing a meal.
- Digestion of some foods will not be be adequate due to the bloackage of enzymes.
- Fat digestion will be decreased greatly because bile will be blocked too.
Explanation:
Breakdown of sugars and proteins occurs by the digestive juices secreted by the pancreas (pancreatic juice) while the bile duct is concenred with the emulsification of fats.
Highly alkaline bicarbonate juices are also produced and secreted by pancreas which raise the pH of the duodenum.
Thus, when both of them are absent, digestion of the food will be affected and becomes impaired and also causing the pH of duodenum to turn acidic. Also the bile salts, bilirubin and biliverd in the bile juice which are important for emulsification of fats and their consequent digestion.
Hence,
- Lumen of duodenum will be acidic as compard to normal environment of the lumen of abdomen when processing a meal.
- Digestion of some foods will not be be adequate due to the bloackage of enzymes.
- Fat digestion will be decreased greatly because bile will be blocked too.
Answer:
Many years ago scientists believed that protein, DNA is not the genetic material because of many reasons like DNA is made up of only four type of nucleotides while proteins are made up of 20 different types of amino acids. So the building blocks of protein are way high than DNA.
Most of the cellular function is performed by proteins, not DNA. The three-dimensional shape of protein is much higher than nucleic acid. So as protein heterogeneity was high therefore it was considered as a molecule of genetic information instead of DNA.

The answer based on the given description above is the term CAPUT. The caput is the area of the bone among dogs that is rounded. Typically, this is found at the top of the femur bone in dogs or at the end of the femur and <span>fits into the acetabulum. Hope this helps.</span>
