Answer:
They probably use aerobic respiration.
Explanation:
A travel distance of 11.500 kilometers in 9 days covered by flying surely requires a lot of energy.
- If cells are fermenting, the ATP (energy) they generate only comes from glycolysis, which produces 2 ATP molecules.
- If they are using aerobic respiration, glucose is completely oxidized to CO₂ through glycolysis and the Citric Acid Cycle, and the electrons enter the electron transport chain to finally reduce oxygen into water. In the complete process, up to 36 ATP molecules are produced.
In sum, aerobic respiration is much more efficient to generate energy than fermentation, so it's probably the main metabolism of the flight muscles in bar-tailed godwits.
Answer:
2. Stimulating antibody production.
Explanation:
Answer:
Temperature is an essential aspect in any experiment as it can affect the various variables of the experiment. It can affect the result and outcomes of an experiment as per the interaction various molecules shows with the temperature.
In molecular biology related experiments that deals with the protein related experiments are also effected by the temperature as enzymatic reactions are slow on low temperature and proteins are also act like enzymes. On high temperature protein may lead to increase in collisions of the molecules of protein and fasten the enzymatic reaction and may lead to degrade the protein.
Answer:
about 525 billion sperm cells
Explanation:
In fact, the average male will produce roughly 525 billion sperm cells over a lifetime and shed at least one billion of them per month. A healthy adult male can release between 40 million and 1.2 billion sperm cells in a single ejaculation.
Answer:
The correct answer is: (A).
Explanation:
- In the question, it is mentioned that the algae can grow under the conditions of "enough sunlight" and "enough nutrients".
- Sunlight reaches the algae, by first falling on the surface made up of ice and snow and then refracting from there into the top layer of the ice where the algae grows.
- However, the capability of both snow and ice to reflect sunlight is far more than that of refracting sunlight.
- Therefore, the amount of light received by the algae is similar in absence or presence of the layer of snow on the top layer of ice.
- However, on deposition of snow on the layer of the ice, the weight of the ice increases and it sinks below into sea water.
- This allows more nutrient rich sea water to percolate into the ice and reach the algae.
- The algae receive more nutrients from the sea water and hence is capable undergoing better metabolism and growth.
- Hence, more algae are produced under such a situation.
