The digestive tract of the frog is well vascularized because it aids in the absorption of nutrients.
The digestive tract of a frog is a hollow long tube that extends from the mouth to the anus which helps in the ingestion and digestion of food.
The digestive tract of frog has the following characteristics:
- alimentary canal of the frog is not long, that is, it is short.
- It has accessory organs of digestion such as liver, gall bladder and pancreas.
All the digested food substances are absorbed at the small intestine due to the presence of microvilli.
This microvilli is made up of a central core that is vascularized, that is, it contains artery, vein and lymphatic capillary.
Therefore, the vascularized microvilli of the small intestine of frog help in the absorption of nutrients.

Answer:
The correct answer is E.
Explanation:
The options are incomplete, here are the complete options:
A) Both populations would be large and diverse, retaining all of their original alleles in their original frequencies.
B) Both populations would be very small and genetically uniform, having lost many of their original alleles.
C) The population in location A would be large and diverse, retaining all of its alleles in their original frequencies. The population in location B would have reduced genetic diversity and different allele frequencies than it did originally.
D) The population in location A would be large but would show a reduction in genetic diversity and altered allele frequencies. The population in location B, however, would retain its original genetic diversity and allele frequencies.
E) The population in location A would be large, while the population in location B would be small, but both would be equally diverse genetically and have the same allele frequencies as one another.
The answer is E because upon examining the example given in the question, we can say that after reproducing several generations, the flowers in both locations are going to go back to their original numbers and the location A population will be large, location B population will be small but they will not be any different genetically than they were before. They will retain their allele frequencies and differences.
I hope this answer helps.
Answer:
The correct answer is - It is the most common genetic disease in the United States.
Explanation:
Cystic fibrosis is the genetic disease that affects the several body system and organ such as lungs and digestive system. This hereditary disease is autosomal recessive.
It is not common in ethnic populations such as African Americans and Asian Americans while in white population of US it is a very common genetic disease as it occurs in one individual in every 2500 to 3500 white infants.
Thus, the correct answer is - It is the most common genetic disease in the United States.
Answer:
The peasant farmers operate mainly in the rural environment of the country. They operate on very small holdings using mostly traditional method because, their income is relatively low and the capacity to save is poor. Therefore needs for credit in order to meet the small farmers output and input
