Traits are the expression of alleles combination in a genotype, and depend on the inherited alleles and the inheritance pattern. Option D. Jane can say that she and Matt inherited eye color from their mother.  

Traits are the expression of the allelic combination in a genotype. The expressed phenotype will depend on the alleles inherited from each parent and the inheritance pattern.

According to the segregation principle, alleles separate during gamete formation. And during fertilization, two gametes from different parents merge to produce a zygote.

Each gamete carries one of the parental alleles. During fertilization occurs a combination of alleles that will express a phenotype.

Traits inheritance do not depend on each other, they are inherited by separate.

In the exposed example, eye color and hair type expression depend on the combination of the alleles in each genotype. And each trait is independently inherited from the other one.

Equivalent resistance: 13.589 Ω

Explanation:

R series = R1 + R2 + R3 ...

[tex]\frac{1}{R_{eq} } = \frac{1}{R1} +\frac{1}{R2} +\frac{1}{R3} ...[/tex]

Find the equivalent resistance of the right branch of the circuit:

[tex]R_{eq} = R_{2} +R_{3} \\R_{eq} = 20.7 + 25.8 = 46.5 ohms[/tex]

[tex]\frac{1}{R_{eq} } = \frac{1}{19.2} +\frac{1}{46.5}\\\\\frac{1}{R_{eq} } = 0.0735887097\\\\R_{eq} = 13.5890411[/tex]

The initial velocity of the train  is 12.56 m/s.

The initial velocity of the train can be determined by using the first kinematic equation as shown below;

v = u + at

u = v - at

where;

u = 30.56 - (36 x 0.5)

u = 12.56 m/s

Thus, the initial velocity of the train  is 12.56 m/s.

To find the final volume of oxygen, we have to use Boyle's law which states that the volume of a gas is inversely proportional to the pressure of the gas provided that temperature remains constant.

v ∝ 1/p

[tex]v = \frac{k}{p} \\k = pv\\p_1 v_1 = p_2 v_2[/tex]

Let's substitute the values into the equation and solve.

[tex]p_1v_1 = p_2v_2\\101325*300 = 16630 * v_2\\30397500 = 16630v_2\\v_2 = \frac{30397500}{16630} \\v_2 = 1827.87cm^3[/tex]

1/80 Hour...................

Answer:

0.58 L

Explanation:

For this problem we need to simply use the ideal gas equation to create a proportional comparison for the initial information to the final information.

(P_1 * V_1) / T_1 = (P_2 * V_2) / T_2

Using this, we can solve for V_2 to find the new volume of the gas once pressure and temperature changes.

(P_1 * V_1) * T_2 / T_1 = (P_2 * V_2)

(P_1 * V_1) * T_2 / (T_1 * P_2) = V_2

Consider our givens:

P_1 = 110atm

T_1 = 303K

V_1 = 2L

P_2 = 440atm

T_2 = 353K

Now we simply plug in these values to the equation to find the new volume, V_2.

(P_1 * V_1) * T_2 / (T_1 * P_2) = V_2

(110atm * 2L) * 353K / (303K * 440atm) = V_2

77660 atm*L*K / 133320 K*atm = V_2

0.583 L = V_2

Hence, the new volume is 0.583 L.

(b) The angular displacement of the flywheel during this acceleration is 17,455.6 rad.

(c) The torque required to accelerate the flywheel is 35.23 Nm.

The average angular acceleration of the flywheel is calculated as follows;

[tex]\alpha = \frac{\Delta \omega}{t} \\\\\omega_f = 1850\frac{rev}{\min} \times \frac{2\pi \ rad}{1 \ rev} \times \frac{1\min}{60 \ s} = 193.76 \ rad/s\\\\\alpha = \frac{\omega _f - \omega_i}{t} \\\\\alpha = \frac{193.76 -0}{3\min\times 60 \ s} \\\\\alpha = 1.076 \ rad/s^2[/tex]

The angular displacement of the flywheel during this acceleration is calculated as follows;
