Answer:
Option B, Observation 2
Explanation:
The four main observation of Darwin’s areas follows –
Observation 1 – Variation occurs in the species with time leading to evolution. Offspring of two parents vary distinctly in traits such as height, color, weight etc. These variations are also affected by the surrounding environment
Observation 2-
Based on observation 1, Darwin concluded that offspring inherit traits from their parents. These traits improve the odds of survival and only genetic traits will be passed. Traits developed in an individual due to environment will not be passed on.
Observation 3 –
Offspring compete among themselves to survive.
Observation 4
The fittest among the competing species for survival will survive and pass on its traits to the next generation.
Since here the Pigeon breeders want to exemplify the looks (a genetic trait) of parents to their offspring, observation 2 applies here
Hence, observation b is correct

Answer:
The reactants and the products of photosynthesis and cellular respiration are the same but switched around.
Explanation:
For photosynthesis light energy, carbon dioxide, water are needed to create glucose and the<em> waste product</em> is oxygen. But for cellular respiration the things needed to create energy to move around are oxygen and glucose. Mitochondria (aka the powerhouse of the cell) breaks down the glucose to make ATP energy (Adenosine Triphosphate). Plants store some leftover oxygen for cellular respiration. So basically, photosynthesis and cellular respiration kinda depend on each other.
