Answer:
1,250,000 shrimps per m³
Explanation:
Population density refers to how dense an area is per unit area/volume, and it is calculated by dividing the number of individuals in that area (population) by the area/volume of that area. That is;
Population density = population (N)/volume
According to this question, a certain lake has a volume of about 480 m³ that harbors a 600 million of freshwater shrimp. This means that;
Population density of the lake = population of shrimps ÷ volume of lake
Population density = 600,000,000 ÷ 480
Population density = 1,250,000 shrimps per m³
Because it is heavier air :)
Answer:
In the above question the ratio of phenotype is asked but the options given aren't according to phenotype hence the options need correction.
But, if you consider the ratio of genotype then option ( A= AaBb x aabb a. The A and B genes are on separate chromosomes ) would be the correct answer.
Explanation:
We can say that the water is the solvent, and the powder is the solute. This is also a solution altogether.
<span>Explanation:- A solute is the thing being dissolved into the solvent. While the solvent is what when the solute is being dissolved in. Together, they make a solution. </span>
The statement water is easily polluted..... is true. Water is pretty much the world's best solvent. So even toxic substances are easily dissolved in it and when that happens they pollute the water.
