What is the definition of density anomaly ?

Biology
1 answer:
Ahat [919]3 years ago
5 0

Answer:

Most liquids become monotonically denser when cooled from room temperature, but liquid water reaches its maximum density at approximately 4°C, below which it expands to become less dense as it is cooled further. To explain this density anomaly, several ideas have been proposed.

The type of inheritance that involves the partial expression of two different<br> alleles is called
belka [17]

Answer: Incomplete dominance

Explanation:

In incomplete dominance, both alleles are expressed but have become blended giving rise to a new trait with one also been more noticed than the other although both are expressed. For instance a red flower and a white flower are crossed, giving rise to a pink flower. As compared to codominance, both alleles are equally expressed and are equally dominant. For example, a white college crossed with a black hen giving rise to a black and white (checkered) chick.

WARRIOR [948]
Semi permeable membrane will allow something to pass  through them and something not and it will allow on the basis of size particles
while differentialy permeable will include other factors also other than size and will depend on the need of the cell
this is the main difference between them

What is the pH if 20 mL of pH = 2 solution is diluted to a final volume of 600 mL?
Mashutka [201]

Explanation:

Hydrogen atoms contain 1 proton and 1 electron while being devoid of neutrons. When they lose their electron they form an ion or H+, a particle carrying a unit of positive charge.  pH measures how basic or acidic a water-based solutions are, with a formula for pH is

pH = -log[H+].

...where pH is -base 10 log of the concentration of hydrogen ions within the solution.

Initial volume= 20 mL

Final volume= 600 mL

# of dilutions= \frac{600}{20} = 30

for a pH 2= [H+]= 10^{=2}

∴ [H+]=  \frac{10^{-2}}{30} = 3.333 * 10^{-4}

and pH is an antilog of [H+]= - log \frac{10^{-2}}{30} = 3.333 * 10^{-4}

∴pH = 3.47
