The following is a list of distinguishing traits that distinguish mammals from other classes:
Warm-blooded mammals are the only animals that give birth to young.In practically all sorts of ecosystems, they are the most prevalent animal form.Because they have mammary glands, they can make milk to feed their young.existence of the Neocortex area of the brainSebaceous glands and sweat glands are present on their skin (sudoriferous glands).Animals' bodies are covered in hair and fur, which helps them adapt to their surroundings.They are heterodont, meaning they have a variety of teeth.Additionally, mammals have cervical vertebrae.It has a dicondylic skull.Learn more about mammals here:

Answer:
1. nuclear waste
radioactive waste material, for example from the use or reprocessing of nuclear fuel.
2. crust
In geology, the crust is the outermost solid shell of a rocky planet
3. mantle
A mantle is a layer inside a planetary body bounded below by a core and above by a crust.
4. core
Earth's inner core is the innermost geologic layer of the planet Earth. It is primarily a solid ball with a radius of about 1,220 km, which is about 20% of Earth's radius
Explanation:
Answer:
Nuclear Waste :- Nuclear waste is the material left over in the reactor. This waste is radioactive and needs to be stored safely away from humans because it is dangerous and toxic to living things.
The Crust:- the crust is the outermost solid shell of a rocky planet, dwarf planet, or natural satellite. It is usually distinguished from the underlying mantle by its chemical makeup; however, in the case of icy satellites, it may be distinguished based on its phase.
Mantle:- A mantle is a layer inside a planetary body bounded below by a core and above by a crust. Mantles are made of rock or ices, and are generally the largest and most massive layer of the planetary body. Mantles are characteristic of planetary bodies that have undergone differentiation by density
Inner and outer core:- outer core is the third layer of the Earth. Earth's inner core is the innermost geologic layer of the planet Earth.
Lithosphere:- lithosphere is the rigid, outermost shell of a terrestrial-type planet or natural satellite
Geological Time:- geological time, the extensive interval of time occupied by the geologic history of Earth.

Answer:
The nephew
Explanation:
The dog's foot prints are overlapping the shoes that are overlapping the tire marks from 3 different tires, if the dog is his seeing dog then it would make sense that the dog's foot prints are next to his and they're going in the same direction, and since the dog's footprints overlap the others it means that they were there last.
People were confused so I'll resay it. The dog is the nephew's seeing dog, so he walks beside him. And if the dog's foot prints are overlapping all of the other's, that means the dog was there after all of the rest of them, and if the nephew is with the dog then the nephew was there last.

A mover loads a 100 kg box into the back of a moving truck by
pushing it up a ramp. The ramp is 4.0 m long and the back of
the truck is 1.5 m high. The mechanical advantage of the ramp
is
(Round to the nearest tenth)
7
Explanation:The following data were obtained from the question:Mass (m) of box = 100 KgLength (L) of ramp = 4 mHeight (H) of ramp = 1.5 mMechanical advantage (MA) of ramp =? Mechanical advantage of a ramp is simply defined as the ratio of the length of the ramp to the height of the ramp. Mathematically, it is given by:Mechanical Advantage = Lenght / height MA= L/H With the above formula, we can obtain the mechanical advantage of the ramp as follow:Length (L) of ramp = 4 mHeight (H) of ramp = 1.5 mMechanical advantage (MA) of ramp =?MA = 4/1.5MA = 2.7Therefore, the mechanical advantage of the ramp is 2.7

4. Tectonic plates are located on the earth's crust and upper most mantle(lithosphere).
6.Innercore is made of iron and nickel.
The summary should be at least a paragraph long and include information about plate tectonics, three kinds of boundaries, subduction, and how convection currents move tectonic plates
Plates can move away or closer together. In result of the moving there are earthquakes, mountains, volcanoes, etc. There are divergent, convergent, and transform boundaries. The convection currents move them across the crust in the path formed by the boundaries.
Answer:
Correct answer: B). Global climate is changing due to burning of fossil fuels and deforestation.
Forest holds a large amount of carbon, plants are known to absorb carbon dioxide from the atmosphere as they grow, that carbon dioxide is stored in plants in the form of carbon in plant's roots, leaves and in the soil. When trees are cut down, that stored carbon is released in the environment in the form of carbon dioxide, which accounts for approximately 18% of global greenhouse gas emission.
The burning of fossil fuel like coal, petroleum, oil, gas for the energy purpose is one of the major contributors for the rising level of carbon dioxide in the atmosphere, which leads to global warming and affect the climate.
Hence, the correct answer would be option B.

what does acceleration mean???
Answer:
Acceleration is the rate of change of velocity. Usually, acceleration means the speed is changing, but not always. When an object moves in a circular path at a constant speed, it is still accelerating, because the direction of its velocity is changing.

Explanation:
As the Sun heats the ocean, the water evaporates, turning into a gas. Sometimes this gas meets cooler air, and the gas changes into drops of water. This process is called condensation. Drops of water fall back down to Earth again as precipitation, which can be in the form of rain, snow, sleet, or hail
three phases of water cycle are

1. How is the Moon cycle an example of the sun, moon and earth interacting?
2. Why does the moon appear completely dark once a month?
Answer:
The moon orbits the earth because of the pull of the earth and so does the earth orbits the sun because of its pull. Because of the way they move relative to each other, we see phases of the moon and eclipses.
The moon appear completely dark once a month because at that time of the month, the moon passes through the same part of the sky, with it's dark or unilluminated side faces Earth.

The lithosphere is the solid, outer part of the Earth. The lithosphere includes the brittle upper portion of the mantle and the crust, the outermost layers of Earth's structure. It is bounded by the atmosphere above and the asthenosphere (another part of the upper mantle) below.
Geologic time, the extensive interval of time occupied by the geologic history of Earth. ... Modern geologic time scales additionally often include the Hadean Eon, which is an informal interval that extends from about 4.6 billion years ago (corresponding to Earth's initial formation) to 4.0 billion years ago.

Cherise sets identical magnetic carts on two tracks. At the end of each track is a blue magnet that cannot move. Cherise can move the carts one space to the left or one space to the right. Which movement will result in the largest increase in potential energy?
a
Moving the cart on Track 1 one space to the right (→).
b
Moving the cart on Track 2 one space to the left (←).
c
Moving the cart on Track 2 one space to the right (→).
d
All these movements will result in the same change in potential energy because they each move a cart the same distance.
Answer:
it's d
Explanation:
The movement that will result in the largest increase in potential energy is D. these movements will result in the same change in potential energy because they each move a cart the same distance.
Potential energy refers to the energy that's possessed by a body when it's at rest. Kinetic energy is the energy that's based on the motion of an object.
In this case, we can see that the carts are moved one space either to the right or left. Therefore, the movements will result in the same change in potential energy.
