HELP PLEASE!!!!!! The bar-tailed godwit is a type of shorebird that makes an annual migration from Alaska to New Zealand and back. The birds make each 11,500-kilometer (7,145-mile) trip by flying over the Pacific Ocean in about nine days, depending on weather, wind speed, and direction of travel. One bird was observed to make the entire journey uninterrupted, a feat that is comparable to a human running a nonstop seven-day marathon at 70 kilometers per hour (43.5 miles per hour). Would you expect the flight (breast) muscles of bar-tailed godwits to use mainly aerobic respiration or fermentation? Explain your answer.

Answers

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.

2. What does an animal need to survive and grow?

Answers

Answer: Food and water and shelter

Explanation: First, food is need to replenish your energy. All animals need food. This is a part of the food chain. Here's a example:

A bear (imagine a image of one right here)

A bear eats fish

A fish (imagine a image of one right here)

Well what does a fish eat?(it depends but for the purpose of this example I'm just gonna say smaller fish

Smaller fish (imagine a image of one right here)

This is just a rudimentary example of a food chain. The real one is a whole lot bigger.

Pt 2. of explanation. Water. In case you have gone thirsty of water grab some now:) Water is essential for all living organisms. Why? Because you need water to replenish the lost fluid from sweat. Yes, even if you don't work out, your body still sweats.

Shelter. think of it like this, you have a home(probably) and you need a place to stay. What do you do? You go back to your house. Well animals also need a place to stay. Just think of it like that. i personally have a snake den in my backyard lol.

I really hope that this answer helps,  if it did maybe mark my answer as brainiest,

Hope I helped,
