Answer:
See the explanation below.
Explanation:
Chemical digestion in the small intestine relies on the activities of three accessory digestive organs: the liver, pancreas, and gallbladder.
- The digestive role of the liver is to produce bile and export it to the duodenum.
- The gallbladder primarily stores, concentrates, and releases bile.
- The pancreas produces pancreatic juice, which contains digestive enzymes and bicarbonate ions, and delivers it to the duodenum.
The liver, pancreas, and gallbladder are considered accessory digestive organs, but their roles in the digestive system are vital.
Answer:
- PLQ (Double Recombinant gamete)
- plq (Double Recombinant gamete)
Explanation:
Cross:
Parentals) pLq/PlQ x plq/plq
Gametes) pLq (Parental) plq (Parental)
PlQ (Parental)
pLQ (Recomb)
plQ (Recomb)
PLq (Recomb)
Plq (Recomb)
PLQ (Double Recom)
plq (Double Recom)
Parentals)
- p----L-----q
- P.....l........Q
Simple recombinant)
Recombination occurs between p and L, OR between l and q.
- P----L-----q
- p......l.....Q
- p----L-----Q
- P.....l........q
Double recombinant)
Recombination occurs between p and L, AND between l and q.
- p-----l------q
- P......L.......Q
Answer:
Phenotypic changes:
When Rhodobacter is cultured in total darkness for multiple generations, the ability to produce it's own photopigment reduces with time with little or no ability to undergo its own photosynthesis due to absence of enzymes or pigment for photosynthesis.
It becomes expensive for the Rhodobacter to undergo photosynthesis. This allows mutants that can grow in the dark to take over from the culture grown in the dark.
Evolutionary processes:
It's natural selection that allows the fittest organism to survive. As in the case of the mutants
Organic matter in soil is also called humus.
