Why do simple animals, such as flatworms and sea stars, survive without special circulatory systems but more complex organisms, like reptiles and humans, cannot?

Answers

Answer 1

Answer:

Flatworms get most of their oxygen through diffusion.

Explanation:

The flatworms and the tapeworms all are single-celled organisms and don't have any complicated structure or compound type of the cells and thus can survive with the presence of the gills like that of the complex organism have. Their flatness gives them a greater surface area to absorb more oxygen and they can take the oxygen from the skins.

b. Relative humidity
c. Absorption
d. Angle of incidence
e. Albedo

Answers

Answer:

e.Albedo

Explanation:

Albedo is the reflectance of solar energy from the earth’s surface. Albedo is said to determine the amount of shortwave radiation to be absorbed by surfaces. When initial absorption of shortwave radiation is limited, it impacts the longwave energy radiated by the earth’s surface, as well as energy availability for evapotranspiration and energy to be converted to sensible heat. Ice, barren land, and sand have higher albedo, which causes higher reflectance of shortwave radiation.

Which of these would be indications that a given mountain range was NOT formed by subduction:

A. It is not along an ocean coastline.


B. There are no volcanoes.


C. There a glacial caps.


D. There are deep valleys.

Answers

It is not along an ocean coastline. and there are no volcanoes. Hence options A and B are correct.

What are mountain ranges ?

The mountain ranges are sorts of hill ranges that are arranged in a line form and are connected by the ground. They form a mountains system or a group of mountains and have been aligned at the same height at the same frequency nd speed. They have been firmed due to the result of the tectonic activity.

Find out more information about the ocean floor.

brainly.com/question/626506.

The correct answer is option (b) because deep valleys are more characteristic of mountain ranges formed by other processes, such as erosion or the collision of continental plates.

Mountain ranges formed by subduction typically exhibit certain characteristics due to the nature of their formation process.

Subduction occurs when one tectonic plate moves under another, leading to the melting of the descending plate and the creation of magma that rises to the surface, often resulting in volcanic activity. Here's the logic behind the correct options:

B. There are no volcanoes: Volcanoes are a common feature in mountain ranges formed by subduction, as the rising magma can erupt at the surface to form volcanoes.

D. There are deep valleys: Mountain ranges formed by subduction tend to have a more jagged and steep topography, with less pronounced deep valleys.

The other options do not necessarily indicate that a mountain range was not formed by subduction:

A. It is not along an ocean coastline: While many subduction zones are found along ocean coastlines, this is not a strict requirement. Subduction can also occur in intra-oceanic settings or along continental margins that are not necessarily coastal.

C. There are glacial caps: The presence of glacial caps does not provide information about the origin of the mountain range. Glacial caps can form on any high mountain range, regardless of how it was formed.

Answers

Answer:

Option (A)

Explanation:

The use of the word "although" is a subordinate conjunction that makes the whole first part of the sentence a subordinate clause.

The second part of the sentence provides an added role of the ice particles while the last part of the sentence gives the demerit of these ice particles. The whole sentence depends on the independent clause which is the last part of the sentence.

So, the form of the sentence is correct with the middle part adding an extra detail of the subject, while also completing the meaning of the whole sentence. The sentence needs no change.

Thus, the correct answer is option (A).

The key word in that question is "range" of temperatures. When it's cold, it gets really cold and when it's hot, it gets really hot. In areas near large bodies of water, there is also water in the atmosphere, (know as "humidity").
There is a property of matter know as "specific heat". A substance with a high specific heat is hard to heat up but also hard to cool down. It is easier for a substance with a high specific heat to maintain a steady temperature. Water has a high specific heat. It is hard to heat it up and hard to cool it down So areas with a lot of water, including atmospheric humidity, are harder to get hot and harder to get cold. In areas where there is little humidity because they're far away from large bodies of water, it is easier to heat up the atmosphere and also easier to cool it off. So you have a larger range of temperatures. In the desert it is hot during the day and cold at night. In the rain forest, (where there is very high atmospheric humidity) it can be very hot during the day and stay hot at night.
Get it?

Answers

Answer:

Temperature difference occurring in various terrains is due to terrain construction.

Explanation:

As it is rule of nature that every material is different in physical and chemical properties to others. Sand has very high absorption capability of gases and heat. As the day shines desert get hot because sand consisting of various materials mostly glass and silicon reflects the light and due to which humidity level decreases and day become hot. In night there is no light so internal vibrational momentum of atoms comes on its original pace it means that their drift decreases so night is cold.

Forests on other hand face humidity and sunlight in the day and in night humidity level does not considerably decreases and heat gets trapped which is absorbed in the day.

​During the early years of Earth, lighter elements such as silicon, magnesium, and aluminum rose to the surface, forming Earth’s crust.True / False.

Answers

Answer:

TRUE

Explanation:

The earth is comprised of three distinct layers namely the core, mantle and the crust. The core is the extreme interior layer which is comprised of the denser elements like iron, nickel and other siderophile elements. Thee denser minerals are deposited, by sinking into the core of the earth forming the highest density layer. The core was formed about 1 to 1.5 billion years back.

Whereas, the least dense elements were concentrated in the upper region of the earth forming the crust. These are the lighter elements so it did not get sink into the bottom. But still many of these elements are found in association with the core rocks. There occurred constant evolution on the crustal portion of the earth.

Thus, these elements are found in larger proportions in the crust and were formed during the initial formation of the earth.

Hence, the above-given statement is True.

If you compress geologic time into a single year, how much time has elapsed since Columbus arrived in the New World?

Answers

Answer: 3.6 seconds

Explanation: Geologic time is a way of measuring time based on events in the history of the Earth. If we compress this into one year, a single geologic year equals 4.6 billion years because the planet  was formed 4.6 billion years ago.  

Columbus arrived in the New World in August 1492, 528 years ago.

If 4.6 billion years = 1 year in geologic time,

528 years = 528 X  [tex]\frac{1X365daysX24hoursX60minutesX60seconds}{4600000000}[/tex]

=3.6 seconds

(I broke the year down into seconds by breaking it down into days, then hours, minutes and seconds because the value is very small)

So, if we compress geologic time into a single year, only 3.6 seconds have elapsed since Columbus arrived in the New World

Final answer:

Compressing Earth's 4.54 billion-year lifespan into one year, every second represents 144 years. Hence, the 528 years since Columbus arrived in the New World amounts to roughly 3.6 seconds in a geologic year.

Explanation:

If we consider geologic time compressed into a single year, then the arrival of Columbus to the New World happened just seconds ago. Earth's age is around 4.54 billion years. If we compress this time span into one calendar year, each second would represent 144 years (roughly). Columbus arrived in the New World in 1492, which is about 528 years ago. Therefore, the elapsed time since Columbus arrived in the New World, in terms of a geologic year, would be approximately 3.6 seconds.

Shifting cultivation is most commonly found in which climate region?

Answers

Final answer:

Shifting cultivation is mostly found in the tropical climate regions. It is a method of cultivation where farmers cut down and burn vegetation on a piece of land, cultivate it for a few years until its fertility diminishes, after which they move to a new area.

Explanation:

The practice of shifting cultivation is most commonly found in the tropical climate regions. This form of cultivation, also known as slash-and-burn or Sweden agriculture, involves clearing a piece of land by cutting down and burning the vegetation. After a few years, when the fertility of this land declines, farmers move on to a new area and repeat the process. Many tropical regions such as parts of Asia, Africa, and South America are suitable for shifting cultivation due to their warm climate and high rainfall which leads to rapid regrowth of vegetation.

Imagine a scientist is studying a sedimentary rock formation that spans the three most recent geologic eras. Rock layers from each era are present in the rock formation. In what order, from top (closest to the surface) to bottom (deepest), should the scientist expect to find layers from each geologic era.

Answers

Answer:

Top- Cenozoic (youngest)

Medium- Mesozoic

Bottom- Palaeozoic (oldest)

Explanation:

The geological time scale is usually referred to as the ordered arrangement of major geological events that has taken place in the past. It is comprised of 3 distinct geological eras, namely the Palaeozoic, the Mesozoic and the Cenozoic.

Of these 3 eras, the oldest is the Palaeozoic (about 540 to 250 million years ago), followed by the Mesozoic (about 260 to 66 million years ago), and lastly is the Cenozoic (about 66 ,million years to present). All these 3 eras are characterized by the presence of fossil assemblages, that helped the geologists in constructing the geological time scale.

Answer:

Cenozoic

Mesozoic

Paleozoic

Explanation:

When layers of sedimentary rock are not disturbed by other geologic processes, the youngest layers are nearest to the surface, and the oldest layers are closest to the bottom.

According to the geologic time scale diagram, the current and most recent geologic era is the Cenozoic. The Mesozoic came before the Cenozoic, and the Paleozoic came before the Mesozoic.  

So the scientist should find that the layers closest to the surface are from the Cenozoic. Layers farther down will be from the Mesozoic; layers ever farther down will be from the Paleozoic. This is shown below.

Summed over the entire surface of the Earth, the rate of spreading at divergent boundaries is ________ lithospheric consumption at subduction zones.

Answers

Answer:

Equal

Explanation:

In a divergent plate boundary, two plates move away from one another and new materials are deposited along the center of this boundary, which is commonly known as the mid-oceanic ridge.

On the other hand, in a convergent plate boundary, two plates move towards each other, resulting in the formation of a subduction zone. The denser plate subducts below the less dense plate and melts at the asthenosphere layer. Here, the crust is consumed or destructed.

The total land areas on earth always remain conserved. This means that the portion of the crust that is destroyed in the convergent plate boundary is balanced by the portion of the newly formed crust that occurs along the mid-oceanic ridge in the divergent plate boundary. This is how the plate movement is responsible for the conservation of total landmass on earth.

Thus, the rate at which plates diverges is equal to the rate at which the plate converges.

The rate of spreading at divergent boundaries is equal to lithospheric consumption at subduction zones when considering the entire surface of the Earth.

The rate of spreading at divergent boundaries is equal to lithospheric consumption at subduction zones when considering the entire surface of the Earth.

Divergent boundaries are areas where tectonic plates move apart, resulting in the creation of new lithosphere through volcanic activity. In contrast, subduction zones occur when one tectonic plate is forced beneath another, leading to the consumption of lithospheric material.

As the Earth's surface is a closed system, the amount of lithosphere being created at divergent boundaries must be equal to the amount being consumed at subduction zones.

Which type of geologist studies the geology of airborne electromagnetics, gravity, magnetics, magnetotellurics, radiometrics, rock properties, and seismicity?

Answers

Answer: A Geophysicst studies all that.

Explanation:

Final answer:

A geophysicist is a type of geologist who studies various geophysical methods such as airborne electromagnetics, gravity, and seismic surveys to understand Earth's subsurface characteristics for scientific and resource exploration purposes. They also analyze data such as seismic amplitudes to deduce the impedance or 'hardness' of geological layers, aiding in identifying resources and geologic features.

Explanation:

The type of geologist who studies the geology of airborne electromagnetics, gravity, magnetics, magnetotellurics, radiometrics, rock properties, and seismicity is known as a geophysicist. These geologists utilize exploration methods to interpret the Earth's subsurface characteristics, including the layers of the core, mantle, and crust. Through techniques like seismic surveys, geophysicists can create images of what lies beneath the surface by sending sound waves into the ground or ocean and recording how these waves reflect off various strata.

Different types of rocks and sediments will alter the waves' velocity, which are then recorded by geophones. These recordings, known as seismic amplitudes, allow geologists to analyze the impedance or 'hardness' of subsurface strata, aiding in identifying rock types, potential resources like water or petroleum, and geologic features.

The study of stratigraphy is crucial in providing data about Earth's history and can involve collecting sediment cores and conducting seismic surveys that are stored and analyzed to deduce geological properties. Repeated seismic surveys offer temporal insights into changes over time. The integration of knowledge from various geophysical methods enriches our comprehension of the Earth's geology for scientific and resource exploration purposes.

Explanation:

a) A physical measure is the one that can measure the water, temperature, structure of the soil, etc. is a characteristic that can show characteristics of the soil without changing it nature.

A Chemical measure will indicate some other requirements like pH, concentration of a nutrient, etc. This kind of measure can be modify is the crop need more nutrient or a different pH to grow.

b) Advantages and disadvantages will be different depending the studies to make. One advantage in all of them is that is easy to get and will give crops with high percentages to obtain harvest, avoid sickness, etc.

The great disadvantage is that in most of the measurements, is needed an instrument that has a cost and need some reactants some of them or calibration.

Hope this info is useful.

Final answer:

One chemical soil test that could be performed is a pH test, which measures the acidity or alkalinity of the soil. One physical soil test that could be performed is a compaction test, which measures the density and compactness of the soil. The pH test allows specific crop recommendations, while the compaction test helps determine soil suitability and management practices.

Explanation:

A) One chemical soil test that could be performed is a pH test. This test measures the acidity or alkalinity of the soil. The result of the pH test can provide information on whether the soil is suitable for specific crops or plants. For example, certain plants prefer acidic soil, while others thrive in alkaline soil. By knowing the pH level of the soil, the Soil and Water Conservation Service (SWCS) can make recommendations on which crops or plants would be best suited for the area.

One physical soil test that could be performed is a compaction test. This test measures the density and compactness of the soil. The result of the compaction test can indicate how well the soil drains, how easily roots can penetrate the soil, and the overall health of the soil structure. The SWCS can use this information to recommend soil management practices that improve drainage, prevent erosion, and promote healthy root growth.

B) One advantage of the pH test is that it provides specific information about the soil's acidity or alkalinity, which is important for selecting the appropriate crops or plants. One disadvantage is that the pH test alone does not provide a complete picture of the soil's fertility or nutrient content. Additional tests may be necessary to determine the availability of nutrients.

One advantage of the compaction test is that it assesses the physical properties of the soil, including drainage and root penetration. This information is crucial for determining the soil's suitability for agriculture or land use. One disadvantage is that the compaction test requires specialized equipment and expertise to perform accurately.

Final answer:

Using the age and distance from the Hawaiian hot spot of the island of Kauai, it's calculated that the average speed of movement for the Pacific Plate over the last 5.1 million years is approximately 9.27 cm/year.

Explanation:

The islands formed by the Hawaiian hot spot allow us to calculate the speed of plate movement. The island of Kauai, which is 5.1 million years old, is now approximately 473 km away from the hot spot. If we consider that distance and time are related to speed, dividing the distance Kauai traveled (473,000m) by the time it took (5.1 million years) gives us an average speed of movement for the Pacific Plate. To convert this to centimeters per year, we find that the Pacific Plate has an average speed of approximately 9.27 cm/year.
