Answer:
a. lactic acid fermentation
Explanation:
Under conditions of intense exercise, the oxygen gas obtained by pulmonary respiration may be insufficient to meet the needs of muscle cells in the work of obtaining energy from cellular respiration.
However, even in the absence of oxygen gas, our muscle cells can release the available energy in glucose, leading to even smaller amounts of ATP molecules. Under these conditions, muscle cells perform lactic fermentation, a process that is virtually identical to glycolysis (the first set of cellular respiration reactions), except that pyruvic acid is transformed into lactic acid with the formation of 2 ATPs. Despite the lower energy yield, fermentation ensures the energy supply to the muscle. Lactic acid formed under these conditions has been associated with muscle pain and fatigue characteristic of intense physical exercise. Recent research, however, has shown that pain is caused by muscle fiber micro-injuries rather than lactic acid as it is rapidly metabolized and eliminated.
Explanation:
It would allow them to examine and see the similarities and differences of the species richness data among sets with different sample. Moreover, it is not just for measuring the variety and diversity of the species, but at the same time of knowing and understanding diversity at advanced taxonomic stages. Generally, the number of species is tested to foresee the number of kinds of species in a specific community. It is also used to analyze species diversity of newly examined ecosystems, which includes micro-biomes of humans, along with applied studies in community ecology, for instance understanding the impacts of pollution on communities as well as other management applications.

Answer:
Watching a baby hummingbird grow up can be a very rewarding experience. Knowing what to look for will help you understand what the hummingbirds are doing and why they are doing it.
Costa's Hummingbird, Calypte Costae, Nest with Eggs, California, USA
Baby hummingbirds are hatched out of hummingbird eggs. When a mother hummingbird is laying an egg, she can be seen sitting on her nest and shaking alternated by wiggling every few seconds. Mother hummingbirds will usually have two eggs laid on different days. The little eggs will be about the size of a pea or small jellybean. Even though the eggs will be laid on different days, both the eggs will usually hatch on the same day. The mother hummingbird can do this by not completely starting the incubation process until the second egg is laid.
The female hummingbird is the only one who will care for these little eggs. A male hummingbird does not assist with any of the childcare. In fact, if a male hummingbird comes around, the female hummingbird will consider his brightly colored feathers a threat that will attract predators and will chase him away.
The hummingbird eggs will remain in the nest incubating for approximately 16-18 days before they hatch. If the weather is cooler it may cause them to hatch a few days later. While the eggs are incubating in the nest, the mother hummingbird will sit on eggs to keep them at a constant temperature of 96 degrees.
