"Which of the following has the element correctly matched with its description?
The duodenum is the first section of the small intestine and contains Peyer's patches.
The bile moves upward and backward and pushes the bolus
The bones attaches the liver to the anterior abdominal wall
Tongue toxins prevent water absorption in the large intestine"
Answer:
The duodenum is the first section of the small intestine and contains Peyer's patches.
Explanation:
It is true that the duodenum is the first section of the small intestine where Peyer's patches are located. The duodenum is the place where most of the entire digestive process occurs, in addition, it allows food to mix with bile and digestive juices.
Peyer's patches play an important role in immunological surveillance during digestive processes. This is because it allows the destruction of possible pathogens associated with food, or that interfere with digestion in some way.
Answer:
D. Antenna pigments allow more wavelengths of light and more photons to be captured, increasing the efficiency of light capture.
Explanation:
The photosynthetic pigments can be part of the antenna pigments or part of the reaction center. The role of the antenna pigments (large number of protein-bound pigment molecules) is to absorb photons and transfer their energy to the reaction center. Simply saying, antenna pigments are light-harvesting complexes. They are composed of polypeptides, that bind chlorophyll a, chlorophyll b, carotene and xanthophylls.
