Vitek1552 [10]

Answer: supersaturated

Explanation: A supersaturated solution is a solution in which the dissolved solute is more than the solvent can hold at that particular temperature.

A solution is a substance which sontains a dissolved solute. A solution can be saturated, unsaturated or supersaturated.

A saturated solution contains the maximum amount of dissolved solute a solvent can hold at that temperature.

An unsaturated solution contains less amount of solute than the solvent can hold at that temperature, this means that more solute can still dissolve in the solution.

A supersaturated solution contains more solute that can be dissolved in the solvent at that temperature.

(70pts) Recall the story of Three Blind Mice where the farmer’s wife cuts off the mouse tails with a carving knife. Because of t
omeli [17]

Answer:

What will happen to the population of mice that it will keep growing at a tremendous rate without a fear of being caught by a predatory. This will increase the population curve of mice but will decrease the population curve of the cat at similar speed.

What else can happen is that cats will no longer be depending on Mice for their food and they will be finding some alternate food host.

What else can happen is the trait of tailless cannot  be favored by environment as proposed by Lamarack in his theory of evolution that if organism acquires some favorable trait during his life then it is possible that he will pass this trait to offspring. Though this trait is not naturally induced therefore,  there are no chances that tailless mice can born and nature choose it as a favorable trait.

In 1880 August weismenn did experiment of similar nature, he cut off the tails of 20 successive generations of mice abut not a single tailless mouse was born. Therefore, he proved that until nature selects some traits, they are not that easily passed from one generation to another if induced by human.

Conclusion: <em>Therefore, after 50 generation mice will be just like parent mice with tails however they will have good population and less predators.</em>

kipiarov [429]

The graph pictured shows bacterial growth, in a petri dish, in which no additional resources are added over time, The graph pictured shows bacterial growth, in a petri dish, in which no additional resources are added over time.

<h3>How does the bacteria actually grow in the petri dish?</h3>

Sterile powdered agar with nutrients can be mixed with moisture, heated and then rushed into empty petri plates or ready-to-use dishes can be purchased.

The undigestible agar is a gelatin-like substance with a semi solid surface on which the bacteria can grow while they engulf the added nutrients

Thus, option "D" is correct.
