Answer:
D) Enzymes make nonspontaneous reactions become spontaneous
Explanation:
Being spontaneous or non-spontaneous in nature depends on the difference in energy levels between substrates and products of the reactions. A reaction with substrates at higher energy levels than the products are spontaneous ones. On the other hand, the reactions wherein products have higher energy content than the substrates are non-spontaneous.
Enzymes do not change the energy levels of substrates and products, so, they can not make a non-spontaneous reaction to become a spontaneous one. Enzymes only lower down the activation energy for a reaction and thereby make the non-spontaneous reaction to occur at a faster rate.
Photosynthesis is important to living organisms because it is the number one source of oxygen in the atmosphere. ... Green plants and trees use photosynthesis to make food from sunlight, carbon dioxide and water in the atmosphere: It is their primary source of energy.
According to the Punnett square for this cross, 50% of offspring is predicted to have blue feathers. This is because the trait of a blue feather is dominant over the trait of a white feather. Thus, the correct option is B.
<h3>What is Punnett Square?</h3>
Punnett square may be defined as a kind of table in which all of the probable products for a genetic cross between two individuals with known genotypes are presented in a precise manner.
The complete question is described in the image given below:
When a Parakeet that is heterozygous (Bb) for blue feather (dominant) is crossed with a Parakeet that is purebred (bb) for white feather (recessive), the genotypes of the resultant offspring are Bb, bb, Bb, and bb.
In which 50% of the offspring possess blue feathers (Bb) while 50% of the offspring possess white feathers (bb).
Therefore, the correct for this question is B.
