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

Some animals in grasslands can obtain water they need from plants.
Sati [7]

The statement given in this question is TRUE; Some animals in grassland can obtain the water they need from plants.

Grassland is a biome that is characterized by wide range of temperature and uniform distribution of rainfall all through the year. The major plants found in the biome are grasses and herbs. The soil in the biome is not fertile enough for trees to survive there. Different animals can be found in the biome and some of the animals has drought resistance capacity. Some of these animals obtain their water requirement from the grasses, which they consume.

A proton gradient is an important part of both photosynthesis and cellular respiration.
Dennis_Churaev [7]

A proton gradient is an important part of both photosynthesis and cellular respiration because couple the favorable flow of H+ to transport specific metabolites into and out of organelles.

<h3>What is the proton gradient?</h3>

The gradient is sometimes called the proton-motive and can be thought of as a form of energy, force and force in a battery. Like other ions, protons are not able to cross directly through the phospholipid bilayer of the membrane, as the interior of the membrane is hydrophobic.

The proton gradient generated by this manipulation provided a driving force for ATP synthesis in the absence of light. This confirms the chemiosmotic theory, where a chemical potential across the membrane can provide energy for ATP synthesis.

The proton gradient produced by pumping protons during the electron transport chain is used to synthesize ATP.

What are the end products of the electron transport chain?
solong [7]

The end products of electron transport chain are:

Water

Adenosine triphosphate (ATP)

Explanation:

  • Most of the free energy released during the oxidation of  glucose to CO₂ is retained in the reduced co-enzyme NADH and FADH₂, generated during the kreb's cycle.
  • Electron are released from these co-enzymes and are eventually transferred to an oxygen molecule to form water.
  • These transfer of electron from co-enzymes to oxygen molecule occurs through a series of protein complexes in the mitochondrial membrane. And the process is termed as Electron Transport Chain.
  • The large amount of free energy is released during the oxidation of NADH and FADH₂ is used in the production of ATP
