ANSWER: Primary succession
Answer;
-The bacterium would exhibit positive chemotaxis.
Explanation;
-Chemotaxis is the movement of cells or organisms in response to chemicals, whereby the cells are attracted (positive chemotaxis) or repelled (negative chemotaxis) by substances exhibiting chemical properties.
Flavonoids play a crucial role as signal molecules in promoting the formation of nodules by symbiotic bacteria commonly known as rhizobia. The roots of leguminous plants use positive chemotaxis to attract rhizobia. Flavonoids are the chemicals associated with attraction of Rhizobium bacteria.
Answer:
Grasshoppers are primary consumers.
Explanation:
Autotrophs serve as primary producers in a food chain as they can make organic food by the process of photosynthesis. In the given food chain, tall grass is the primary producer. Grasshoppers derive their nutrition from the tall grass. The organisms that derive nutrition directly from the primary producers are said to be primary consumers. This makes grasshoppers primary consumers.
Mice the secondary consumers as they feed on the grasshoppers, the primary consumers. Red-tailed hawks are the top consumers in the given food chain. The bacteria, beetles, fungi, and worms are the decomposers that derive nutrition from the organic matter present in the dead bodies of the red-tailed hawks.
The experiment is to prove that the semiconservative model is more accurate than the dispersive model of DNA replication
<h3>What is DNA replication?</h3>
DNA replication is the process where new copies of DNA are made from existing DNA copies.
DNA replication was suggested to occur in two ways:
- The semiconservative model
- the dispersive mode
The Semiconservative replication produces two helices, each containing one old strand and one new strand
The Dispersive replication produces two helices in which each strand contains alternating segments of old and new DNA.
The semiconservative model is the accepted model because it produces more accurate copies by ensuring continuous replication in the replication mechanism.
Therefore, the experiment is to prove that the semiconservative model is more accurate than the dispersive model of DNA replication.
