A swimmer sprints a short distance for competition. The swimmer is not able to take in enough oxygen to make the ATP needed for the sprint. Which of the following processes is most likely going to occur in the swimmer's muscle cells during the competition? (2 points)
A. Aerobic respiration would continue until oxygen is no longer available, leading to cell death.
B. Aerobic respiration will continue to make the same amount of ATP since oxygen is not required.
C. Anaerobic respiration would be used to produce small amounts of ATP in the absence of oxygen.
D. Anaerobic respiration will produce more ATP than the process used in the presence of oxygen.
<u>Answer:</u>
A swimmer sprints a short distance for competition. The swimmer is not able to take in enough oxygen to make the ATP needed for the sprint. Anaerobic respiration would be used to produce small amounts of ATP in the absence of oxygen and it is the process happens in the swimmer's muscle cells during competition.
<u>Explanation:</u>
- A Swimming sprinter will spend his maximum energy while to cover a short distance in his competition. Quickly he will reduce his oxygen level.
- Oxygen will produce an ATP molecule (Adenosine Triphosphate) which is required for a sprinter.
- The ATP molecule will produce energy for the cells. Aerobic respiration takes place only when in the presence of oxygen.
- While swimming they will not get enough oxygen so the Anaerobic respiration takes place to produce ATP molecule.
Answer: mucilaginous sheath
Explanation:
These algae are known as "blue algae" because of their pigmentation or "cyanobacteria" because they are prokaryotes. Microbiologists classify cyanobacteria in the realm of Eubacteria. They are the only prokaryote algae. The cellular organization is prokaryotic, without nuclei or organelles. Respiration takes place at the level of plasmalemma and thylakoids. In the center (nucleoplasm), cells contain their genome and circular plasmids. Cyanobacteria often also have a mucilaginous sheath common to many trichomes.
These organisms contain several carotenoid pigments, particularly myxoxanthophyll, which does not occur in any other algae group. Some cyanobacteria are strictly phototrophic, others are optional: they are phototrophic when in the presence of light, but may grow in obscurity using an organic carbon source. Others can use a source of organic carbon as well as inorganic carbon, but only in the presence of light.

D. All of the above
Answer:
<u><em>Galapagos finches</em></u><u> have various beak sizes that make foraging for food more successful.</u>
Explanation:
Organisms evolve over time due to changes in their genome. These are pontaneous, and occur in DNA at random. These changes are called mutations and form alleles or different forms of a gene.
Over time within a population, the number alleles increase the variation of the population. These variants may confer specific traits within an individual, that may confer a biological advantage.
Thus, the trait may make the organisms more capable of obtaining food, shelter a mate etc. or ensure survival, i.e. they are able to pass on their genes to the next generation.
