When might a dominant trait appear?

Chemistry
1 answer:
daser333 [38]2 years ago
7 0

Answer:

A dominant allele will always allow a specific trait to show up no matter if we have two dominant copies (BB) or just one (Bb). A trait from a recessive allele will only appear if it is paired with another recessive allele

the student records the concentration of the stock solution of H2O2 to be 0.950 M. The student proceeds to prepare the reaction
lana [24]

Answer:

0.0400M of KI

Explanation:

Molarity is an unit of concentration defined as the ratio between moles of solute and liters of solution.

When you add 10.0 mL of 0.10M KI and 15.0mL, total volume is:

25.0mL = <em>0.025L of solution</em>

<em />

And moles of KI are:

0.0100L × 0.10M = <em>0.00100 moles of KI</em>

<em />

Thus, molarity is:

0.00100 moles / 0.025L = <em>0.0400M of KI</em>

A galvanic cell generates a cell potential of 0.32V when operated under standard conditions according to the reaction above. Whi
Ugo [173]

The complete question is shown in the image attached to this answer.

Answer:

C

Explanation:

Let us quickly remember that the EMF of a cell under non standard conditions in given by the Nernst equation.

This equation states that;

E = E°cell - 0.592/n log Q

Where

E = EMF under non standard conditions

E°cell= standard EMF of the cell

n = number of electrons transferred

Q = reaction quotient

If the reaction quotient is greater than 1 then cell potential is less than the standard cell potential.

The cell that generates the lowest cell potential is the cell depicted in option C because Q has the greatest positive value(Q<1).

The discovery of the electron as a subatomic particle was a result of
swat32

Answer:

4)experiments with cathode ray tubes

Explanation:

when sufficiently high voltage is applied across the electrods, current starts flowing through a stream of particles moving in the tube the negative electrode (cathode) to the positive electrode (anode). These were called Cathode Rays or Cathode Ray Particles

Which type of reaction is represented by this graph?
enot [183]

Answer:  

D. Exothermic.  

Explanation:  

Hello there!

In this case, since the potential energy versus reaction progress diagrams are related to the energetic profile of a chemical reaction, we can set the initial point at the beginning of the reaction as the energy of the reactants and the final point as the energy of the products.

Next, since the change in the enthalpy of a reaction is quantified by subtracting products minus reactants, we can see that the products have less energy than the reactants and therefore ΔH for this reaction is negative, which matches with the definition of D. Exothermic  reaction.

Regards!
