describe how a sound travels from the outside environment to your brain
Answer:
Sound bounces off objects around you an travel close to your body. When sound reaches you the dome shape of your ears let's the sound travel down the ear canal and to your eardrum. When the sound reaches the brain I assume it processes and you assume a sound to what is making the sound. Like fire alarms for example, when we here that specific sound we know to react by evactuating.

The Endangered Species Act was passed in 1973, but many people today feel that the Endangered Species Act has not done enough to protect endangered species from human impacts. do you think that it needs to be updated? Give specific examples why or why not.
Answer:
Absolutely
Explanation:
only 3 percent of species protected by the law have recovered to the point where they are no longer threatened or endangered. The ESA can and should be strengthened so that it not only continues to protect species, but also promotes their full recovery.
In the last 100 years we human beings have eliminated 10 times more species than have disappeared in the past at the natural background rate. Without conservation, we are at risk of losing precious wildlife and depriving future generations of America’s heritage.
With the growing menace of climate change, many more species need our protection. In 1973, there were only 78 species listed in the ESA; now there are almost 1,600.

C. melting of arctic ice leading to higher and higher global
temperatures and more ice melting
D. water moving into the roots of plants and out of leaves
leading to more water moving into the roots
An example of negative feedback is ; ( D ) water moving into the roots of plants and out of leaves leading to more water moving into the roots.
What is a Negative feedback ?A negative feedback is the reverse effect of the output of a stimulus. Feedback is the effect of the output of a system on the stimulus from the origin. Water moving into the roots of plants and out of leaves leading to more water moving into the roots is a negative feedback.because if the water flows into the roots and out of the leaves is suppose to lead to water moving out of the roots.
Hence we can conclude that An example of negative feedback is water moving into the roots of plants and out of leaves leading to more water moving into the roots.

3. The principle of uniformitarianism is a key concept that allows geologists to study Earth's past.
A. What is the principle of uniformitarianism? (5 points)
B. How does this principle make it easier for geologists to understand Earth's past? (5 points)
Answer:
A. What is the principle of uniformitarianism?
Uniformitarianism would therefore be a theory of the Earth characterized by the uniformity of physical laws, processes and the rhythm with which they have acted in nature (gradualism).
B. How does this principle make it easier for geologists to understand Earth's past?
In geology, uniformitarianism has included the gradualist concept that "the present is the key to the past" and that geological events occur at the same rate as they always have, although many modern geologists no longer hold to strict gradualism.

What are the effect of silt on aquatic organisms?Silt refers to small fine particles of sand or mud that forms a suspension in water.
Silt in oceans usually come from rivers opening into the sea
The silt suspended in the water surrounding a coral reef near the coast of a small island community in the Caribbean Sea will originate from rivers and streams opening into the sea.
The silt will reduce the population of algae on the coral reef as they increase water turbidity.
This will reduce fish population in the area and the food source for humans.
Industrial wastes are a source of mercury in lakes.
The presence of mercury will poison the lake and kill the fishes in the lake.
It will also make the water unfit for drinking by humans.

Can snow form with a warm and cold front
Answer:
With a warm front, boundary between warm and cold air is more gradual than that of a cold front, which allows warm air to slowly rise and clouds to spread out into gloomy, overcast stratus clouds. Precipitation ahead of a warm front typically forms into a large shield of steady rain or snow.

It’s multiple-choice I just need the answers please
Answer:
2, 2, 1, 2, 4
Explanation:
Question 1. - Decomposers break apart dead organisms into simpler inorganic materials, making nutrients available to the plants/primary producers.
Question 2. - Energy decreases as it moves up trophic levels because the energy is lost as metabolic heat when the organisms are consumed by other ones from the next level.
Question 3. - Energy moves through an ecosystem in a single direction from the sun to autotrophs/producers, then from producers to heterotrophs/consumers. Never backward from consumers to producers.
Sun ⇒ Producers ⇒ Consumers ⇒ Decomposers
Question 4. - See Question 1.
Question 5. - Autotrophs don't need energy from other organisms. Instead, they use photosynthesis to get their food.
- Note: Fungi cannot make their own food and therefore are not autotrophic. They do not have chloroplasts, instead, they are osmotrophic!
