Answer
Outer Core
Because of the weight of the melting moving metal creates energy
Our planet is shielded from cosmic radiation and charged particles from our Sun by the magnetic field, which is created by the motion of molten iron in the Earth's core. It also offers the framework for compass navigation. Thus, option D is correct.
What role of outer core of earth in magnetic field?Radiative heating and chemical differentiation have caused the Earth's outer core to be in a state of turbulent convection.
The convective kinetic energy is transformed into electrical and magnetic energy through a mechanism that is somewhat similar to a naturally occurring electrical generator.
The magnetic field is not produced by the earth's core, since metals lose their magnetic characteristics at high temperatures.
Therefore, Because of the weight of the melting, moving metal creates energy.

in 2008, engineers at nasa developed the Fermi gamma ray telescope. gamma rays come from the most extreme places in the universe. NASA is studying them because scientists want to learn more about environments in the universe that make gamma rays. this includes objects such as exploding stars. the photograph below is an image taken using the Fermi gamma ray telescope. using the information above, along with your knowledge of the electromagnetic spectrum column where should the Fermi going rate telescope be placed to enable the highest quality images to be recorded by this telescope? A. orbiting in space somewhere outside earth's atmosphere. B at the top of a tall mountain away from all sources of light pollution. C any area on Earth that will allow enough room for a large satellite dish. or D. two opposite locations on earths surface are required, including the north and south pole.

Answer:
Image result for True or false are sun is now the main sequence of its life cycle
The Main Sequence:
The Sun, like most stars in the Universe, is on the main sequence stage of its life, during which nuclear fusion reactions in its core fuse hydrogen into helium. ... For the Sun, this process began 4.57 billion years ago, and it has been generating energy this way every since.

Yes.
Explanation:
Yes, a tree is falling over in a forest make a sound because both the tree and ground are hard surfaces which can produces sound by contact physically with each other. For testing this hypothesis, we have to take a tree and cut that tree. when the tree falls on the ground it will definitely produces sounds by contact physically with the ground when falls with a large force.

9. Which food would you expect to have the lowest lipid levels?
a. Olives
b. Pistachios
c. Wheat crackers
d. Sesame seeds
The food expect to have the lowest lipid levels is sesame seeds. The correct option is d.
What is lipid?Lipids are hydrocarbon-containing molecules that serve as the foundation for the structure and function of living cells.
Lipids include fats, oils, waxes, vitamins (such as A, D, E, and K), hormones, and the majority of the cell membrane that is not made of protein.
Carbon, hydrogen, and oxygen are the same elements found in lipids as they are in carbohydrates.
Lipids, on the other hand, are primarily composed of hydrocarbon chains and contain fewer polar hydroxyl groups. As a result, most lipids are nonpolar hydrophobic molecules.
Sesame seeds are high in saturated fat (15%), polyunsaturated fat (41%), and monounsaturated fat (39%).
According to research, eating more polyunsaturated and monounsaturated fat than saturated fat may help lower your cholesterol and reduce your risk of heart disease.
Thus, the correct option is d.

Which space telescope is used to see distant objects?
The Hubble Space Telescope, often known as HST or Hubble, is an observatory that was put into low-Earth orbit in 1990 and is still in use today.Although it wasn't the first space telescope, it is one of the biggest and most useful ones. It is famous for being both an essential scientific tool and a public relations success for astronomy.The only telescope made with astronaut maintenance in mind is Hubble. Five Space Shuttle trips have been used to replace, improve, and repair the telescope's systems.Since Hubble is orbiting outside of Earth's distorted atmosphere, it can take extraordinarily high-resolution pictures with a lot less background light than ground-based telescopes can.The Hubble telescope and other space telescopes can be used to zoom at distant objects.

Two species benefit from interaction with each other
Example: A hummingbird gets food from the nectar of a flower and then spreads the nectar’s pollen, helping the flower reproduce.
: One species benefits from the interaction, and the other species is harmed but not necessarily killed
Example: Ticks feed on other animals’ blood, which can hurt the other animals.
: One species benefits from the interaction, and the other species is neither helped nor harmed
Example: Egrets rely on cows to stir up dirt and bring food to the surface, but cows do not benefit.

If you tossed a coin a total of ten times and got a total of three heads, what is the probability of tossing heads in your next toss?
In decimal form this is 0.5 and it converts to 50%
===================================================
Explanation:
Assuming the coin is a fair coin, meaning that each side is equally likely to be landed on, this means the probability of flipping heads is 1/2 = 0.5 = 50%
This is true of any flip. The coin doesn't have memory of previous events, so past events do not affect its probability. Each event is independent of any other.
