Explanation:
Gregor Mendel developed the model of heredity that now bears his name by experiments on various charactersitics of pea plants: height (tall vs. Short); seed color (yellow vs. Green); seat coat (smooth vs. wrinkled), etc. The following explanation uses the tall/short trait. The other traits Mendel studied can be substituted for tall and short.
Mendel started out with plants that "bred true". That is, when tall plants were self-pollinated (or cross-pollinated with others like them), plants in following generations were all tall; when the short plants were self-pollinated (or cross- pollinated with others like them) the plants in following generations were all short.
Mendel found that if true breeding Tall [T] plants are crossed (bred) with true breeding short [t] plants, all the next generation of plants, called F1, are all tall.
Next, he showed that self-pollinated F1 plants (or cross- pollinated with other F1 plants) produce an F2 generation with 3/4 of the plants tall and 1/4 short.
A. 1/4 of the F2 generation are short plants, which produce only short plants in the F3 generation, if they are self- pollinated (or crossed with other short F2 plants;) these F2 plants breed true.
B, 1/4 of the F2 generation (1/3 of the tall plants) are tall plants that produce only tall plants in the F3 generation, if they are self-pollinated; these tall F2 plants breed true.
C. 1/2 of the F2 generation (2/3 of the tall plants) are tall plants that produce 1/4 short plants and 3/4 tall plants in the next [F3] generation, if they are self-pollinated. This is the same proportion of tall to short that F1 plants produce.
<span>The car is passed by a motorcycle that is moving faster than it which means both the car and the motorcycle is moving in the same direction. Since both object move in the same direction, the relative speed of the motorcycle would be slower. The speed would be:
relative speed= motorcycle speed - car speed
</span>relative speed= 80MPH- 55MPH= 25MPH
Answer:
53.3
Explanation:
If the objective lens is 3 times the magnification
and the magnification lens is 160X
160÷3=53.33 recurring, rounded down to be
53.3
Hi recent research on the type A behavior pattern suggests that the
*Hostility* subcomponent is the best predicator of subsequent cornet heart disease.
Hope this helps you. Please help me by saying brainliestor or by saying thanks.
Try reading back and think about it. I probably shoudn't help you on that, however. I'm very sorry. But good luck!
