Answer: A (colored feathers.)
Explanation: There are many birds with colors that are variously different on the Galapagos.
So, Darwin carefully observed the finches of the Galapagos island. What he noticed was that they were similar to the mainland finches, but each island finch has different colored feathers.
The regression equation is:
y = 1.15 – 0.251 x₁ + 0.078 x₂ + 0.306 x₁x₂

Where,
x₁ = -0.2508
x₂ = 0.0777
x₁x₂ = 0.3058
Inserting the values,

</span></span>y = 1.15 – {0.251 × (-0.2508)} + {0.078 ×(0.0777)} + {0.306 × (0.3058)}
</span></span></span>
y = 1.15 - (- 0.0629508) + 0.0060606 + 0.935748
y = 1.15 + 0.0629508 + 0.0060606 + 0.935748
y = 1.3125862
Answer:
x₁ and x₂ are main effects (a type of tuna and type of packing liquid) that contribute significant information for the prediction of <span>y.</span>
In autotrophic bacteria, chlorophyll is located in the infolded regions of the plasma membrane.
Autotrophic bacteria are those that can synthesize their own food. The energy can be derived either from sunlight or from chemical reactions. Only a few amount of bacteria are autotrophic. The examples of such bacteria are: green sulfur bacteria, purple sulfur bacteria, heliobacteria, etc.
Chlorophyll is the green colored pigment involved in the process of photosynthesis. The chlorophyll acts as a reaction center that absorbs the energy from sunlight to initiate the process of photosynthesis. The energy absorbed by other pigments is also transferred to the reaction center.
