Answer:
Replacing a lipid containing 18 C fatty acids with one containing 16 C fatty acids.
Given what we know, we can confirm that the basic idea resulting from these studies is that a creature's metabolism is related to its lifespan.
<h3 /><h3>How is metabolism related to lifespan?</h3>
From the studies done and the comparison of the lifespan of certain species in relation to their metabolic rates, scientists have noticed that <u>metabolism</u> and <u>lifespan </u>are inversely proportional. The <u>slower </u>the metabolism of an organism, the <u>longer </u>that organism can live.
Therefore, we can confirm that the basic idea is that a creature's metabolism is inversely proportional to its lifespan, meaning that the faster the metabolism, the shorter the lifespan of the creature in question.

<span>The pancreas secretes digestive enzymes in the slender instincts, these enzymes produce endocrine secretions through the hormones and pass through the blood. Endocrine cells called pancreatic islets secrete insulin and glucagon and have endocrine functions that are formed through the hormones and pass through the bloodstream.</span>
The organism would be a secondary consumer and a carnivore. An example could be an snake in the following food chain: grass -> bunny -> snake
Answer:
Adaptations to a common environment and examples of convergent evolution
Explanation:
Convergent evolution is a process by which two independent and phylogenetically separated organisms, get to develop similar structures or behavior to survive. These structures make possible a better performance in a similar environment. These organisms are morphologically or ethologically similar in their whole bodies or just in parts.
Convergent evolution occurs in different phylogenetic branches independently from each other. It results from the need of different organisms to adapt to a similar environment and to solve a problem from that particular ecological niche. Ecological pressures acting on them might be similar, modeling the organisms´ phenotype. Each evolutive branch ends by developing the same structures, which they both find effective in their environment.
In the exposed example, Ichthyosaurs (reptile) and fishes are separated species on evolutive time, corresponding to different phylogenetic lineages. Both of them inhabit the same aquatic environment. Pressures of the habitat acted on them and modeling their phenotypes. These species need to adapt to living in water, moving, feeding, scaping, chasing, etc. So both species arrived at the same solution. They developed dorsal fins and tails, which are important to stabilize the body in the water while swimming, making it more hydrodynamic and getting to propel better.
