Answer:
Here I hope this can help you with your question! :)
Explanation:
You might be travelling with other astronauts in a journey that will take between seven and 12 months, packed in a tight space. So you’ll need to stretch and probably find a way to have part of the spacecraft spinning to create artificial gravity. Having no gravity for a long time can cause a lot of painful health problems for astronauts. Then there’s the powerful cosmic radiation that comes mostly from our Sun. It can damage electronic equipment on board and create health problems for the crew. You and the crew will have to solve these problems on your own. The atmosphere is not breathable: it is only 1% the thickness of our atmosphere, mostly made of carbon dioxide, argon, and nitrogen with only a small amount of oxygen. Growing plants on Mars is not going to be easy. The soil is really salty and acidic. It is still unclear if we should bring bacteria to Mars to help plants grow (as they do on Earth). Finally, I would say any mistake in flight or during the exploration can hurt or kill you. The room for error is really narrow. Why on Earth would you engage in such a dangerous, life-threatening endeavour? I guess the answer lies in what has made humans explore throughout the centuries. We are always looking for the next frontier.
Answer:
- Travelling from Earth to mass requires a greater magnitude of escape velocity in order to overcome the Earth's gravitational attraction.
- Travelling to Mars is a great distance which is approximately the twice of Earth's distance from the sun (approximately 3.0×10^11 m), hence the Traveller has a possibility of not reaching the destination.
- Travelling to Mars requires a skilled Traveller and experienced, yet those travellers are scarce allover the World.
- It is also very expensive.
- Mars has a different and a greater gravitational attraction than that of the earth, hence a person of earth may not cope with it.
-Mars is very hot than Earth, hence the living on it is affected by the climatic diversion
The less energy a wave has, the smaller its
The less energy a wave has, the smaller its amplitude.
In physics, waves are characterized by their amplitude, which is the maximum displacement of particles from their equilibrium position as the wave passes through a medium.
Amplitude is directly related to the energy carried by the wave. Waves with higher energy have larger amplitudes, whereas waves with lower energy have smaller amplitudes.
For example, in sound waves, higher amplitudes correspond to louder sounds with more energy, while lower amplitudes produce softer sounds with less energy.
In the context of electromagnetic waves, such as light, higher amplitudes represent brighter light with more energy, while lower amplitudes indicate dimmer light with less energy.

the consequences by hunting leather backturtle
Answer:
Dune vegetation would miss a significant source of nutrients if sea turtles go extinct and would not be as stable and not large enough to support the dunes, resulting in increased erosion.
Explanation:
While their range is wide, due to extensive egg collecting and bycatch fisheries, the numbers of leatherback turtles have decreased dramatically over the past century.
The motion of a Foucault pendulum provides evidence that Earth
The motion of a Foucault pendulum provides evidence that Earth rotates. A further explanation is provided below.
Foucault's pendulum demonstration seems to be a very confined, readily produced experimentation with a straightforward, compelling, as well as accessible outcome including to non-scientists.The pendulum moves together in-plane perpendicular somewhere at northern or southern poles.Because unless we ignore the knowledge then the Earth has also been rotating in-universe, this same plane does seem to traverse 360° when the globe completes one full circle.
Thus the above response is correct.

Biodiversity and Humans: Question 5 Tasmanian devils are animals that live in Tasmania and Australia. Tasmanian devils almost went extinct in the 20th century. The existing devils come from very few individuals. What can we say about the Tasmanian devil population?
Answer:
Tasmanian devil population has very low genetic diversity
Explanation:
The species that have experienced recent drastic reductions in their population sizes tend to lose genetic diversity due to a process known as genetic drift (i.e., random fluctuations in allelic frequencies). Tasmanian devils represent a well-known case of this process. In this species, many gene variants (alleles) lost when this species reduced its population size during the 20th century. In consequence, the current population of Tasmanian devils has a very low genetic diversity, where individuals are almost genetically identical.

Answer: during exercise, lactate builds up in muscles and causes a burning pain in the affected muscle
Explanation: Exercise increases the energy needs of the muscles used. Increased energy generation requires increased oxygen. If energy demands exceed the body’s ability to supply oxygen, muscle tissues switch from aerobic to anaerobic respiration.
In anaerobic respiration pyruvate is reduced to lactate. Energy production is <10% as efficient as aerobic respiration, so it must be at a high rate.
C3H4O3 + 2NADH + 2ADP + Pi —> C3H6O3 + 2NAD+ + 2ATP
Reducing intensity of exercise or taking breaks can give the body a chance for recovery. Aerobic fitness will increase ability to supply oxygen.
After exercise, lactate is converted back to pyruvate and to replenishing glucose via gluconeogenesis. The enzyme lactate dehydrogense catalyses the pyruvate/lactate reaction in both directions.
The cumulative effect of exercise and converting lactate back to pyruvate creates an ‘oxygen debt’ which is why we breathe heavily after exercise.
Exercise can lead to dehydration (e.g. sweating) which decreases metabolic efficiency. Additional water intake before during and after exercise prevents dehydration.
It has also been shown that light exercise in the recovery phase after strenuous exercise improves the rate of lactate removal

Which situation would deplete freshwater
Answer:
Water demand is greater than its renewal or recharge rate.
Explanation:
Fossilized evidence of Earth’s first forms of life would consist of?
Answer:
prokaryotes from the precambrian
Explanation:
describe 4 ways a temperature increase of only 1c (global warming) would impact humans and / or ecosystems
Answer:
1. Food cycle- With Global Warming on the rise the food cycle is being thrown off due to some animals dying off because they aren't getting used to the extreme sudden heat this can also affect humans especially if we seafood. Global warming affects the ocean too killing off a lot of sea creatures that we eat sometimes like Shrimp for example. Study shows that Global Warming is heating up the ocean cooking the live shrimp in the ocean.
2. Timing of seasonal changes- Study shows that places that don't get hit by snowy weather in the Wintertime are getting pounded by winter storms. A perfect example of this is East Coast getting hit by wintery weather while West Coast sees some high temperatures with no moisture this is caused by global warming.
3. Extinction Risks- Another study shows that some animals such as elephants, Siberian Tigers, red Pandas are all on the Endangered species list due to the sudden change in the weather because of Global Warming which brings the extinction-level to an almost high rate. People all around the world are trying all they can to prevent animal species to go extinct and as I mentioned before if a species goes extinct it'll throw off the food cycle.
4. Range shifts- Since the temperatures are changing dramatically because of global warming it is causing a lot of species to migrate to a new area this is their way of surviving instead of dying off this can also disrupt the food cycle because if a certain species a predator perhaps moves to a different area the prey species will increase and those predators that migrated to a new area is causing a lot of habitat changes to another species its like natural selection and can cause a pretty bad change
So that is why people are up and arms about global warming and why they want to hurry up and come up with a plan to stop global warming or figure out a way to cool down the Earth because it'll not only end in species' extinction but it can lead to Human extinction.

Are there any parts of the human body that get oxygen directly from the air and not from the blood? i don't pay attention in biology
Answer:
The cornea.
Explanation:
The cornea is the only part of the human body that has no blood supply, it gets oxygen directly through the air. Also, did you know that the cornea is the fastest healing tissue in the human body, therefore, most corneal abrasions will heal within about 24-36 hours.
