My answer will be because these characteristics intervene in the capture and assimilation of the food, having 4 general food behaviors: (1) detritivores, consume a lot of material from the bottom of the water source, (2) herbivores, who consume mostly plant components (filamentous algae and higher plants); (3) periphyton consumers, who are characterized by feeding on microalgae and microinvertebrates and (4) omnivores, in which they indistinctly feed on plant material as an animal of different origin.

Two solutions will be prepared with the mixture of distilled water and stock solution of KMnO4 (10 mM). Give the correct volumes
Yanka [14]

Answer:

See the answer below

Explanation:

<em>Recall that the law of dilution states that the number of moles before dilution must be equal to the number of moles after dilution.</em>

Mathematically,

     molarity x number of moles before dilution = molarity x number of moles after dilution.

For solution A: final molarity = 3 mM, final volume = 2mL, initial molarity of KMnO4 = 10 mM

Applying the equation:

    10 x initial volume = 3 x 2

        initial volume = 6/10 = 0.6

<u>Hence, Tube A should be made with 0.6 mL of 10 mM KMnO4 stock and  1.4 mL of distilled water to give a solution of 2 mL 3 mM KMnO4.</u>

For solution B:final molarity = 8 mM, final volume = 2 mL, initial molarity = 10 mM

    10 x initial volume = 8 x 2

       initial volume = 16/10 = 1.6

<u>Hence, Tube B should be made with 1.6 mL of 10 mM KMnO4 stock and 0.4 mL of distilled water to give a solution of 2 mL 8mM KMnO4. </u>

LUCKY_DIMON [66]

Answer:

Phenotypes

Explanation:

Heritability refers to the extent to which trait variations among individuals are attributable to their differing observable and most often definitive or measurable physical features, often called phenotypes. Examples of this variation could be something like height or eye colour. Basically it has to be traits that depend on genetics that environmental factors
