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

Tasya [4]

Answer: Blood plays a very important role before cellular respiration. The blood provides oxygenated blood for the aerobic processes that takes place during cellular respiration. Glycolysis, link reaction, Kreb's Cycle and Electron Transport Chain are all the aerobic process of Cellular respiration that requires oxygen. Without blood aerobic cellular respiration cannot occur as the source of oxygen is blood. The blood provides oxygen before cellular respiration. After cellular respiration the waste materials are carried away by blood only.

Hence, blood plays an important role before cellular respiration.
