B: All three plants have a common ancestor that had leaves.

Explanation:

got it right on ed! :)

The supporting statement by the information in the chart is all three plants have a common ancestor that had leaves. The correct option is B.

A characteristic or quality that commonly identifies someone, somewhere, or anything. A person or thing's characteristics are the traits or aspects that belong to them and help people identify them. The distinctive qualities or traits of anything are its characteristics. Consider traits as the attributes that set one object or a person apart from another. The chameleon, for instance, is known for its capacity for camouflage.

The chart is showing different plants and different characteristics. The common ancestor in the three plants is their leaves.  

Therefore, the correct option is B. All three plants have a common ancestor that had leaves.

Answer: C: Density increases

Explanation: As you go closer towards the center of the Earth, pressure increases. The layers of rock get pack tightly together, causing them to be more dense.

As we move from the surface to the interior and center of the Earth, density increases.

Four layers, three solid and one liquid (molten metal nearly as hot as the sun's surface), make up the interior of the Earth. A massive iron ball with a diameter of roughly 1,500 miles (2,400 kilometers) makes up the deepest stratum.

The iron isn't pure; researchers think it also contains trace amounts of nickel, sulfur, and other components. Although different measurements have been made, it is most likely between 9,000 and 13,000 degrees Fahrenheit (5,000 and 7,000 degrees Celsius).

The outer core, a shell of liquid iron, is located above the inner core. This layer may be between 4,000 and 5,000 degrees (7,000 to 9,000 degrees Fahrenheit) colder but still highly hot.

Therefore,  As we move from the surface to the interior and center of the Earth, density increases.

Answer:

S - Savannas are typically found in tropical or subtropical regions.

S - Savannas tend to have more trees and shrubs.

S - Savanna's climate is drier than that of a grassland.

G - Grasslands are found in temperature regions.

G - Temperature Grasslands are mainly devoid of trees, receive less rainfall than Savannas & endure broader temperature extremes.

G - Grasslands make up 25 percent of the Earth's land surface and dominate in regions with limited rainfall, which prevents forest growth. This results from nearby mountain ranges that cause rain shadows over adjacent open-range lands.

B - Both represent the world's richest and most diverse ecosystems. They both provide a home for a quarter of the world's population and a habitat for thousands of plants and animals.

B - Many species gather in vast numbers, graze on the varied grasses, and can be found nowhere else on Earth. The coexistence between wildlife and grasses is key to healthy ecosystems. Animal migrations regenerate the landscapes, by controlling pests, dispersing seeds, and trampling invasive species. Through this partnership, grasslands and savannahs generate vital benefits for both people and nature.

B - Ecosystems such as these two in specific are essential for climate mitigation – they store carbon, locking it deep in the soil and extensive root systems. They are the source of or support many of the world’s biggest rivers and wetlands, ensure food security, support livelihoods, and are embedded in the cultural identity of millions of people.

Answer:

When the tide goes out, the water retracts back into the sea. The water moves between the sun and the moon which pulls the water back into the sea.

Explanation:

Tides are caused by the gravity of both the moon and the sun “pulling” at the water in the sea. Because the Earth is constantly turning, the “pull” of gravity affects different places as each day goes on - so when the tide is “out” in your area, it is “in” somewhere else.

From the diagram of the rock cycle the missing part is ( B ) ; Melting

Magma is a hot liquid/semi-liquid rock that is usually formed under the earth due to high pressure and temperature present in the inner core of the earth. magma is obtained by the melting down of existing rocks ( Igneous, sedimentary and metamorphic rocks ) under high pressure and temperature in the earths core.

Magma is released to the earth surfaces during volcanoes therefore the missing term  in the rock cycle is melting

Hence we can conclude that from the diagram of the rock cycle the missing part is Melting.

Answer:A) Auxins make plant cells grow larger towards the light causing it to bend.

Answer:

A.

Auxins make plant cells grow larger towards the light causing it to bend.

Explanation:

The auxins go more in the shady side, and that is why there are more auxins in the shady side, but in the illuminated side, there are less auxins. That will cause a bend in the growth of the plant towards the light source because the shady side has more auxins to make it grow. This is the reason why when there are auxins in a plant, they start to grow towards light.

Humans directly change the dynamics of the water cycle through dams constructed for water storage, and through water withdrawals for industrial, agricultural, or domestic purposes. Climate change is expected to additionally affect water supply and demand.

Fossil fuel production is another human activity that places considerable strain on drinking water — and not just because fracking and coal mining use a great deal of water, but because their waste products can pollute groundwater, and therefore drinking water, as well.Water resources face a host of serious threats, all caused primarily by human activity. They include pollution, climate change, urban growth, and landscape changes such as deforestation. Each of them has its own specific impact, usually directly on ecosystems and in turn on water resources.

S.B.

Answer:

the egg yolk is the Earth's inner core

the egg white is Earth's outer core

the egg shell is the mantle

the cracked pieces of egg shell is the lithosphere

the entire egg is earth

Explanation:

I'm not sure about all of these, but it should hopefully be correct. I'm not sure about what the whole egg would be. I hope this helps you anyways :)

Here is a possible interpretation of what each part of the egg represents in the Tectonic Egg Model:

Egg shell: represents the Earth's crust, which is the outermost layer of the planet that consists of solid rocks and varies in thickness from about 5 km to 70 km.

Cracked pieces of egg shell: represent the boundaries between tectonic plates, where earthquakes and volcanic eruptions often occur due to the movement and interaction of the plates.

Egg white: represents the asthenosphere, which is a partly molten layer beneath the crust that behaves like a plastic material and allows the plates to move and slide.

Egg yolk: represents the Earth's core, which is the central part of the planet that consists of a solid inner core and a liquid outer core, and generates the Earth's magnetic field.

the differences between the types of tectonic plates and their resulting observations in the asthenosphere by using different colors or types of egg shells to represent different plate types (e.g., oceanic vs. continental) and by observing how they interact and move relative to each other in the egg white layer.

For example, oceanic plates are denser and tend to sink beneath continental plates at subduction zones, whereas continental plates are thicker and tend to form mountain ranges when they collide.

The hypotheses of the Tectonic Egg Model could be tested by observing how the egg shells move and interact with each other when the egg is shaken or rotated, and comparing the results to the expected behaviors based on the types of plates and the properties of the asthenosphere.

If the model is too simplistic or inaccurate, the experimental results may not match the expectations or observations of real-world tectonic activity.

Some shortcomings of using the Tectonic Egg Model as a replicable of the Earth include:

The egg is much smaller and simpler than the Earth, so it cannot capture the full complexity and scale of tectonic processes.

The egg shell is brittle and does not behave like real rocks, which can deform and change over time due to pressure, temperature, and chemical reactions.

The egg yolk may not represent the Earth's core accurately, as it does not have the same density, composition, or behavior as the real core.

To create a more accurate model of Earth's tectonic plates, a scientist could use computer simulations or physical experiments that involve more realistic materials and conditions, such as:

Using a sphere or globe that approximates the size and shape of the Earth, and using different layers of materials (e.g., clay, sand, water, oil) to represent the crust, mantle, and core.

Using a rheometer or other mechanical device that can apply controlled forces and stresses to the materials, and measure their deformation and response over time.

Using sophisticated computer software that can simulate the behavior of tectonic plates and their interactions based on known physical laws and data from real-world observations (e.g., GPS, seismology, satellite imaging).
