Answer:
The correct answer is option b. "streamlined bodies in dolphins and ichthyosaurs".
Explanation:
An homoplasy is defined as a trait that is shared between two different species but that they do not originate from a common ancestor. An example of homoplasy is the streamlined bodies in dolphins and ichthyosaurs. Ichthyosaurs were reptiles, not mammals like modern dolphins, therefore their similar streamlined bodies evolved separately.
Answer:
Acquired (or somatic) mutations occur at some time during a person's life and are present only in certain cells, not in every cell in the body. These changes can be caused by environmental factors such as ultraviolet radiation from the sun, or can occur if an error is made as DNA copies itself during cell division.

Explanation:
Glycolysis refers to the metabolic procedure of transforming one molecule of glucose into two molecules of pyruvate via an arrangement of ten enzymatic catalyzed reactions.
Glucose + 2ADP + 2NAD+ + 2Pi -> 2 pyruvate + 2ATP + 2NADH + 2H+ + 2H2O
In this, from three molecules of glucose six molecules of ATPs are generated.
On the other hand, the pentose phosphate pathway can take place to metabolize dietary pentose sugars obtained due to the digestion of nucleic acids as well as to reorganize the carbon skeletons of dietary carbohydrates into gluconeogenic/glycolytic intermediates (F6P and GAP).
The pentose phosphate pathway is a prime producer of NADPH for the production of fatty acids. This pathway is not created to generate ATP.
Here's a picture to help explain and show the steps:
