None of the above? I’m guessing, secondary, primary and tertiary doesn’t sound right !
Answer:
The correct answer is C) 1 L of 1.0 M NaCl
Explanation:
NaCl is a ionic compound so it dissociates in water into Na⁺ and Cl⁻ ions. Glucose is a covalent solute so it does not dissociates into ions. So, when we dissolve NaCl we have twice the amount of particles in solution in comparison with glucose. According to this:
A) and B) are solutions with the same concentration (0.5 M) but NaCl solution will have more solute particles than glucose.
C) and D) are solutions with more solute amount because they are more concentrated (1 M), but NaCl solution will have more solute particles than glucose solution ( 1 mol of Na⁺ ions + 1 mol of Cl⁻ ions).
The solution with the greatest solute particle number is C).
Answer:
Explanation:
Unicellular or multicellular, most cyanobacteria are a characteristic blue green, but can also be green, brown, yellow, black, or red.
Answer: habitat preference
Explanation:
One of the driving factors for ecological speciation that does not allow interbreeding between the members of a species is habitat preference. Some members of a species have a different preference for habitat than others in terms of habitat preference. They reside and do not interbreed in various environments. These two populations of a species live in diverse environments acquire genetic differences over generations and interbreed only with members of their own populations.
