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:

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.

Answer:

D. A warm front brings rain in humid air on occasion, but a cold front brings thunderstorms in summer.

Explanation:

Weather can be defined as the atmospheric conditions of a particular area over a short period of time. Some examples of elements of weather includes clouds, precipitation, air pressure, wind, relative humidity, temperature etc.

In meteorology, precipitation is the end result of condensation of atmospheric water vapour falling under gravity from clouds. Precipitation is rain, snow, sleet, hail, drizzle, pellets, ice and graupel falling from the sky.

A warm front refers to the transition zone or boundary where a mass of cold air is being replaced by a mass of warm air.

On the other hand, cold front refers to the transition zone or boundary where a mass of warm air is being replaced by a mass of cold air

Generally, the weather caused by a warm front compare to the weather caused by a cold front based on the fact that, a warm front brings rain in humid air on occasion, but a cold front brings thunderstorms in summer.

D) A warm front brings rain on occasion, but a cold front brings thunderstorms in summer

Explanation:

A warm front brings gentle rain or light snow, followed by warmer, milder weather. Commonly, when the cold front is passing, winds become gusty; there is a sudden drop in temperature, and heavy rain, sometimes with hail, thunder, and lightning. Lifted warm air ahead of the front produces cumulus or cumulonimbus clouds and thunderstorms.

Answer:

Cleavage and fracture are not commonly used to identify minerals

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.

Answer:

Wave length x Wave frequency

Explanation:

The wave length is measured in meters X the wave frequency, measured in hertz (Hz)

Answer:

The speed of a wave is a property of the medium changing the speed actually requires a change in the medium itself. If the medium does not change as a wave travels, the wave speed is constant.

TO CALCULATE IT

Wave Speed Formula

Speed of the tsunami (meters/second) is equal to the square root of g (the acceleration due to gravity, which a constant 9.81 meters/second) times the water depth (d) at which the disturbance occurred (meters).

Explanation:

a. i believe it's called lactic acid? when you don't get enough oxygen to the muscle, it starts to cramp up

b. you can do stretches to ease up tense muscles

c. because it gets oxygen to your muscles

d. to hydrate, helps to keep the muscle cells to relax and more hydrated, becoming less irritable.

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

Menzies et al. Blood lactose clearance during active recovery after an intense running bout depends on the intensity of the active recovery. J. Sports Sci 2010; doi 10.1080/02640414.2010.481721
