Answer:
Convergent evolution
Explanation:
Convergent evolution is a type of evolution of similar features and/or structures between organisms that are not phylogenetically related. This type of evolution is known to create analogous structures/organs that exhibit similar or the same functions but were not present in the last common ancestor of these taxa. An example of analogous structures (and therefore also of convergent evolution) are the wings of bats and of insects (e.g., butterflies). Conversely, divergent evolution is a type of evolution where species phylogenetically related, i.e., species that share a common ancestor, evolve and accumulate differences over time.
The correct answer is True
For peeps in the future, so you dodnt almost get it wrong. Your welcome :3
<span>When Prophase is occur, during this stage, changes occur both in the cytoplasm and in the nucleus. Within the nucleus, the chromatin fibers become more tightly coiled and folded, forming discrete chromosomes that can be seen with the light microscope. The nucleoli disappear. Each duplicated chromosome appears as two sister chromatids joined together, with a narrow waist at the centromere.In the cytoplasm, the mitotic spindle begins to form as microtubules rapidly grow out from the centrosomes which begin to move away from each other.</span>
Options are not provided in the question. The complete question is:
What exactly is the link between the extra glycogen associated with carbohydrate loading and enhanced performance in endurance sports?
a. The extra glycogen serves as a reservoir for glucose, which serves as the main fuel molecule for increased cellular respiration, resulting in more available ATP.
b. The extra glycogen undergoes the process of deamination, which is the first step in the breakdown of the carbon chains needed for ATP synthesis.
c.The extra glycogen is used during beta oxidation, which is a series of chemical reactions resulting in the formation of acetyl coenzyme A, which is essential to start the citric acid cycle of aerobic cellular respiration.
d. All of the listed responses explain the link between carbohydrate loading and enhanced performance in endurance sports.
Answer:
a.
Explanation:
Glycogen is a multibranched polysaccharide of glucose which represents the main storage form of glucose in the body.
During sports, a lot of energy is required. The glycogen serves to fulfil all the enrgy requirement of the body. The extra glycogen associated with carbohydrate or glucose serves energy to cellular respiration due to increase in physical actvities and provide more ATP.
Hence, the correct option is a.
