The gene for tallness (T) in a pea plant is dominant over the gene for shortness (t).
astra-53 [7]

Answer:

C. 75%

Explanation:

From a heterozygous cross (Tt x Tt) the produced offspring would consist of:

  • 25% TT -it would be tall-.
  • 50% Tt -it would be tall as the gene T is dominant-.
  • 25% tt -it would not be tall-.

Thus the produced offspring that would be tall is (50% + 25%) 75%. The answer is option C.

`Let's just consider the concept of stoichiometry without any confusing chemicals. Here is a generic equation: 2A + 6B ? 3C. If
lesya [120]

Answer:

Option D. 5.5

Explanation:

The equation is this:

2A + 6B  ⇒  3C

With the amounts that we were given, let's determine which is the <em>limting reactant</em>

2 A reacts with 6 B

4 A will react with ( 4 .6)/2 = 12B

I have 11 B, so the limiting is B

6 B react with 2 A

11 B will react with (11 .2 )/6 =3.66 A

I have 4 A, so A is the excess.

6 B produce 3 C

11 B will produce ( 11 .3)/6 = 5.5C

Red lights on a traffic light have a frequency of 4.3 X 10^15 Hz. What is the red light’s wavelength in meters? (Speed of light
Juliette [100K]

Answer:

The correct answer to this problem is B. 7.0 X 10^-8 meters

Explanation:

To solve this problem, we have to use the following equation:

c = λν, or speed of light = wavelength*frequency

If we substitute in the values we are given by the problem, we get:

3.00 * 10^8 m/s = (4.3 * 10^15 Hz)*(wavelength)

wavelength = 6.98 * 10^-8 m

Since the given value has 2 significant figures, our answer should similarly include two significant figures since the operation in the problem was multiplication.

Therefore, the answer is B. 7.0 X 10^-8 meters.

Hope this helps!
