Chemical defenses are an important part of plant-herbivore interactions. The production of these chemical defense compounds resu
mylen [45]

The correct answer is: Individuals that produce chemical compounds are better protected from herbivores and are able to produce more young than individuals that do not produce the compounds.

Natural selection acts on variations-differences in phenotype that exist among individuals. If a certain trait contribute more to survival and reproduction (individuals with that variant survive more than individuals with other variant), natural selection will favor that trait. In this case, production of chemical compounds is favored over non-producing trait.

The table below summarizes Mendel’s results for the F2 generation. Mendel’s Results Plant height 787 tall 277 short Flower color
Gnom [1K]

Answer:

2001

Explanation:

This question showcases a table that displays Mendel's results (figures) when he crossed pea plants and observed different characters in the plant. Mendel worked with different phenotypic characteristics in the pea plant.

According to the table, the result were for seven characteristics including height, flower color, flower position, pod color, pod shape, seed color, seed shape. Based on the observation of the number of F2 offsprings that possessed dominant trait and recessive trait for each character, we will notice that it follows an approximate phenotypic ratio of 3:1

1. Plant height 787 tall 277 short (3:1)

2. Flower color 705 purple 224 white (3:1)

3. Flower position 651 middle of stem 207 end of stem (3:1)

4. Pod color 428 green 152 yellow (3:1)

5. Pod shape 882 inflated 299 constricted (3:1)

6. Seed color 6,022 yellow X green

7. Seed shape 5,474 smooth 1,850 wrinkled (3:1)

This 3 dominant : 1 recessive ratio is the ratio got in the F2 offsprings when he observed the seven characteristics in pea plants. Hence, the seed color will also follow the same 3:1 ratio

Therefore, 2001 is the result Mendel obtained in the F2 offsprings for the recessive trait of seed color characteristics in his experiment, which actually depicts the 3:1 ratio. Hence, X (green seed color) is 2001

Antoine wants to convert millimeters into kilometers. which operation should he choose? he should multiply millimeters by 1,000.
Vadim26 [7]

1\ km =1,000,000\ mm

so

1\ mm =\frac{1}{ 1,000,000}\ km

therefore

<u>The answer is</u>

to convert millimeters into kilometers

Antoine should divide millimeters by 1,000,000
