In an ecosystem, the herring population was reduced by fishermen. As a result, the tuna, which feed on the herring, disappeared.
Mkey [24]

Answer:

                         -------> Herring---------> Tuna

                      /                      

Sand eels ⇒/

                     \

                        \

                           ---------> Cod -----------> Seabirds

Explanation:

Food Web is the complex interplay of  interconnection between food chains and a graphical representation of what-eats-what in an ecological community.

From the question, the herring population was reduced by fishermen and as a result the tuna which feed on the herring disappeared. This implies that the tuna depends solely on the herrings for feeding. without they wont survive.

As we proceed, we were being told that the sand eels which are eaten by herring, increased in number.

If we pay close attention, we will understand that due to the reduction of the herrings  made the sand eels to increased in numbers. The point is that herrings also feed on the sand eels, but as the herrings is being reduced by some anthropogenic factors caused by the fishermen the sand eels increased.

Also, the fishermen overharvested the sand eel population and the aftermath effect shows reduction in Cod and Seabirds. This implies that Cod feeds on sand eels and Seabirds feeds on Cod, but as the food chain is being disrupted by overharvesting of the sand eels, the effect was shown by a decreased in the Cod and Seabirds.

Therefore, the best diagrammatic representation that could fit best for this explanation is:

                        -------> Herring---------> Tuna

                      /                      

Sand eels ⇒/

                     \

                           ---------> Cod -----------> Seabirds

On a hike through the forest, you notice a population of 100 flowering plants that all look identical (phenotypic clones), and t
givi [52]

Answer:

1a. False

1b. False

Explanation:

They are genetic clones which make them identical so there is no difference in phenotype which is the key mechanism for evolution to occur through natural selection.

- since they are of one phenotype(genetically identical) genetic drift can not occur. For genetic drift to occur, there must be a change in the frequency of one allele within a population over a period of time and this genetic variation must occur randomly for a genetic drift to occur.

What is happening in the food vacuoles that causes the yeast to turn blue?
Rom4ik [11]
Answer;
Food vacuoles that causes the yeast to turn blue indicates active digestive processes in the cell.The blue represents the mature food vacuoles as some yeast cells have now entered, and beginning the digestive process. 

Explanation; 
The ingested yeast cells appear red during early stages of being eaten. Later some of the yeast cells will enter into the food vacuoles to which acidosomes have fused, lowering the pH. The yeast cells within the food vacuole will turn blue, indicating active digestive processes in the cell. It is used for yeast uptake in the paramecium food vacuoles.
