Answer:
Observation is essential in science. Scientists use observation to collect and record data, which enables them to construct and then test hypotheses and theories. Scientists observe in many ways – with their own senses or with tools such as microscopes, scanners or transmitters to extend their vision or hearing
The basic idea of a hypothesis is that there is no pre-determined outcome. ... A key function in this step in the scientific method is deriving predictions from the hypotheses about the results of future experiments, and then performing those experiments to see whether they support the predictions
Answer:
The units and their physical quantities are the second for time, the metre for measurement of length, the kilogram for mass, the ampere for electric current, the kelvin for temperature, the mole for amount of substance, and the candela for luminous intensity.
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.
