Look at the diagram above of a marine food web. What might happen to this ecosystem if the non-native populations of smelt and a

lewife increase greatly?
Question 1 options:


1.The smelt will eat the alewife.


2.The salmon will starve.


3.The smelt and alewife may out-compete the native fish by consuming all of the zooplankton.


4.Nothing should happen to this ecosystem if the populations of smelt and alewife increase greatly.

The correct answer is 3- <span>The smelt and alewife may out-compete the native fish by consuming all of the zooplankton.

The diagram tells us that zooplankton is eaten by smelts and alewifes. If these two species increase in number, less of the zooplankton will be left for plankton-eating fish, which is a native type of fish, to eat.
</span>
<span> smelt and alewife eat most of the existing plankton so, they are out-competing the native fish.</span>

Marianna [84]

Answer:

Explanation:

Active cellular transport:

  • It is the movement of molecules against the concentration gradient  (from low concentration to high).
  • Active transport requires expense of energy supplied by ATP.
  • It is a rapid way to transport of large sized molecules.

Passive cellular transport:

  • It is the movement of molecules along the concentration gradient (from high concentration to low).
  • Passive transport does not require expense of energy.
  • It is a slow process and small sized molecules get transprorted.

Create an experiment where you would use both a Southern blot and a Northern blot to determine if a newly isolated bacterium con
natta225 [31]

Answer:

■Gene sequences would be used to make Probes for both the Southern and Northern blots.

■The probes will be used to view the presence of each gene with the use of isolated genomic DNA obtained from the isolated bacterium

■Each probes hybridized to the genome shows the pathway is isolated and point of the genes were involved in the substrate catabolism

■The carbon source in the isolate is derived from the substrate inducing the catabolic pathway as RNA determine transcripts present

■Probes hybridizing to the same sequences would be used to determine the gene activity for the pathway as seen in the southern one

■since all the genes present in the genome couldn't be identified, the northern would be important to work on

■Catabolic pathway is determined by the same genes. Hence, the need for gene/transcript probes to hybridize to the transcriptome.

The conversation between madame valmondé and désirée gives an example of _____. select all that apply.
NeX [460]
The conversation between madame valmonde and desiree gives an example of Foreshadowing; situational irony;
Considering this Quote;
Madame Valmonde "shuddered at the first sight of it.....It was a sad lokking place.......The roof came down steep and black like a cowl, reaching out beyond the wide galleries that encircled the yellow stuccoed house. Big, solemn oaks grew close to it, and their thick-leaved, far-reaching branches shadowed it like a pall."

The imagery in this quote reveals the darkness of a place that is ironically called a shelter, and Madame Valmonde mentions the "pall" that is cast over the house , that being a term related to death.
