Answer; The correct answer for the blank is- Food Chain.

Food chain can be described as a series of living organisms that are dependent on one another as a source of food/ obtaining energy for the survival.

In other words, it represents the flow of energy ( transfer of energy in the form of food) among different living organisms present within an ecosystem.

The organisms in the food chain occupy different ranks ( called trophic level) that occur in a particular order ( such as Producers, primary consumers, secondary consumers, tertiary consumers, decomposers).

Thus, food chain is the right answer.

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:

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

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

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.

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

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.

$\huge \text{Hello there! :)}$

I'm joyous to help you today! :)

Answer:

The conifer phylum also contains the Gnetophyta (Gymnosperms), an order that includes the genera Gnetum, Ephedra, and Welwitschia.

Explanation:

That group includes 70 species across the three genera mentioned above, the difference between the Gnetophytas and other Gymnosperms plants is the presence of vessels, similar to the ones in the flowering plants.

humans developed antibiotics to fight bacterial infections however some antibiotics are no longer effective in killing the bacte

Lapatulllka [165]

Answer:

Changes in genetic makeup occurs with the passage of time.

Explanation:

Antibiotic cause mutation in the bacteria which allowed to develop resistance in the bacteria. This resistance and change in the genetic makeup obeys the theory of evolution which states that all species are changed gradually with the passage of time. The genetic makeup of bacteria also changes with the passage of time and attain resistance due to regular application of antibiotics so due to this resistance, the antibiotic can't work on the bacteria.
