What causes genetic variation in a population

Answers

Answer: Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).

It is true/falseit that when hydrogen cyanide, h c n , dissolves in water, the solution is weakly conducting and acidic in nature. This is because hydrogen cyanide, h c n is a blank that blank support the movement of charge. In addition, since specifically blank formed, the solution is blank.It is blank that when acetone, CH3COCH3, is dissolved in water conducting solution results. This is because acetone, CH3COCH3 is a blank that blank support the movement of charge

The words are:
True, false, weak electrolyte, strong electrolyte, non-electrolyte, does not, does, H+ is, OH- is, no ions are, acidic, basic, neutral.

Answers

Final answer:

HCN is a weak electrolyte that partially ionizes in water and forms an acidic solution as H+ ions are formed, while acetone is a non-electrolyte that does not form ions in water and the resulting solution is neutral.

Explanation:

It is true that when hydrogen cyanide, HCN, dissolves in water, the solution is weakly conducting and acidic in nature. This is because hydrogen cyanide, HCN, is a weak electrolyte that only partially ionizes in water, and hence does support the movement of charge, albeit to a lesser extent than a strong electrolyte. In addition, since H+ ions are specifically formed from the ionization of HCN in water, the solution is acidic.

It is false that when acetone, CH3COCH3, is dissolved in water a conducting solution results. This is because acetone, CH3COCH3, is a non-electrolyte. It does not ionize in water, and therefore does not support the movement of charge. As such, no ions are formed when acetone is dissolved in water and the solution remains neutral.

A rock at the top of a 30 meter cliff has a mass of 25 kg. Calculate the rock’s gravitational potential energy when dropped off the cliff. Assuming that energy is conserved and there is no air friction and gravity is 9.8 m/sec., at the bottom of the cliff the rock’s potential energy is completely converted to kinetic energy. Use the formula for kinetic energy to calculate the rock’s speed at the bottom of the cliff. Show all calculations.

Answers

Lets see:-

We have our formula for potential energy, which we are trying to solve for,

PE = mgh or potential energy = mass * gravity * height

So we know that PE all depends on these.

Height : 30 meters
Mass : 25 kg
Gravity (which is always constant) : 9.8 m/s/s

Now add into formula.

PE = 25*30*9.8
PE = 7350 Joules

Answer: PE = 7350 Joules

Now calculate speed:-

7,350 joules/12.5 kg = speed-squared
588 m²/s² = speed-squared
about 24.248 m/s

Which statement about reversible reactions is correct? At equilibrium, the forward and reverse reactions stop at the appropriate concentrations. At equilibrium, the forward and reverse reactions continue indefinitely. At equilibrium the rate of reaction of products divided by the rate of reaction of reactants equal the equilibrium constant, K.

Answers

The correct answer is At equilibrium the rate of reaction of products divided by the rate of reaction of reactants equal the equilibrium constant, K.

The chemical reactions which occurs in forward direction as well as backward direction under particular conditions is said to be reversible reactions. In these reactions, concentration of reactants and products remain same and both reactions i.e. forward and backward reactions occurs at similar rates.

Equilibrium is the state of reaction in which formation of reactants into products and formation of products into reactants occurs simultaneously at similar rate.

Now, equilibrium constant is equal to the ratio of concentration of the products to the concentration of the reactants.

For example: $A+B\rightarrow C+D$
