The correct answer is; Metals have low electronegativity, so they are conductive because they pass charges easily.
Metals are found towards the left hand side in the periodic table. They are known for their low electronegativity. Metals are electropositive. This means that they loose charges(electrons) easily.
A metallic bond is comprised of positively charged metallic ions and a sea of electrons.These electrons can move freely.
This sea of electrons are the charges that are responsible for the properties of metals such as high conductivity.

3. In the two-kingdom classification following are drawbacks:-
The plants comprised of photosynthetic and non-photosynthetic species. Fungi, that feed on dead organic matter, were placed under photosynthetic plants. There was another class of classification needed were the organisms with the same characteristics were clubbed into one kingdom. This system did not distinguish between the eukaryotes and prokaryotes, unicellular and multicellular organisms and photosynthetic (green algae) and non-photosynthetic (fungi) organisms. There are some organisms which neither fall into plant nor animal kingdom like Lichens.Explanation:-

Rachel is learning about ocean currents. She asked her teacher the cause of Coriolis effect. What should the teacher answer?
A The Coriolis effect occurs due to the Earth's rotation
B. The Coriolis effect occurs due to friction between wind and water.
C. The Coriolis effect occurs due to the Earth's gravity.
D. The Coriolis effect occurs due to moon's gravitation force.
Answer:
A
Explanation:
Earth's rotation is the main reason for the Coriolis effect. The effect deflects anything that flies or flows over a long distance above the ground, proportionate to Earth's spin direction. Even storms can be a result of the rotation; hence, they do not form similarly everywhere on Earth.

PLEASE HELP. Explain how the earth is a system? The more detail you can provide, the better!
Answer:
The earth system is itself an integrated system, but it can be subdivided into four main components, sub-systems or spheres: the geosphere, atmosphere, hydrosphere and biosphere. ... The atmosphere receives energy from solar radiation which warms the earth's surface and is re-emitted and conducted to the atmosphere.
Answer:
When the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun. Like its fellow terrestrial planets, Earth has a central core, a rocky mantle, and a solid crust. Our home planet Earth is a rocky, terrestrial planet. It has a solid and active surface with mountains, valleys, canyons, plains and so much more. Earth is special because it is an ocean planet. Water covers 70% of Earth's surface.
Earth's atmosphere is made mostly of nitrogen and has plenty of oxygen for us to breathe. The atmosphere also protects us from incoming meteoroids, most of which break up before they can hit the surface. Near the surface, Earth has an atmosphere that consists of 78 percent nitrogen, 21 percent oxygen, and 1 percent other gases such as argon, carbon dioxide, and neon.
The atmosphere affects Earth's long-term climate and short-term local weather and shields us from much of the harmful radiation coming from the Sun. It also protects us from meteoroids, most of which burn up in the atmosphere, seen as meteors in the night sky, before they can strike the surface as meteorites. Our planet's rapid rotation and molten nickel-iron core give rise to a magnetic field, which the solar wind distorts into a teardrop shape in space. (The solar wind is a stream of charged particles continuously ejected from the Sun.)
When charged particles from the solar wind become trapped in Earth's magnetic field, they collide with air molecules above our planet's magnetic poles. These air molecules then begin to glow and cause aurorae, or the northern and southern lights. The magnetic field is what causes compass needles to point to the North Pole regardless of which way you turn. But the magnetic polarity of Earth can change, flipping the direction of the magnetic field. The geologic record tells scientists that a magnetic reversal takes place about every 400,000 years on average, but the timing is very irregular. As far as we know, such a magnetic reversal doesn't cause any harm to life on Earth, and a reversal is very unlikely to happen for at least another thousand years. But when it does happen, compass needles are likely to point in many different directions for a few centuries while the switch is being made. And after the switch is completed, they will all point south instead of north.
Explanation:
Our home planet is the third planet from the Sun, and the only place we know of so far that’s inhabited by living things. While Earth is only the fifth largest planet in the solar system, it is the only world in our solar system with liquid water on the surface. Just slightly larger than nearby Venus, Earth is the biggest of the four planets closest to the Sun, all of which are made of rock and metal. The name Earth is at least 1,000 years old. All of the planets, except for Earth, were named after Greek and Roman gods and goddesses. However, the name Earth is a Germanic word, which simply means “the ground.” Earth is the only planet that has a single moon. Our Moon is the brightest and most familiar object in the night sky. In many ways, the Moon is responsible for making Earth such a great home. It stabilizes our planet's wobble, which has made the climate less variable over thousands of years.
Earth sometimes temporarily hosts orbiting asteroids or large rocks. They are typically trapped by Earth's gravity for a few months or years before returning to an orbit around the Sun. Some asteroids will be in a long “dance” with Earth as both orbit the Sun.
Some moons are bits of rock that were captured by a planet's gravity, but our Moon is likely the result of a collision billions of years ago. When Earth was a young planet, a large chunk of rock smashed into it, displacing a portion of Earth's interior. The resulting chunks clumped together and formed our Moon. With a radius of 1,080 miles (1,738 kilometers), the Moon is the fifth largest moon in our solar system (after Ganymede, Titan, Callisto, and Io).
The Moon is an average of 238,855 miles (384,400 kilometers) away from Earth. That means 30 Earth-sized planets could fit in between Earth and its Moon.

Along the inferior surface of the liver are several structures that collectively resemble the letter H. The gallbladder and the round ligament of the liver form the vertical superior parts of the H; the inferior vena cava and the ligamentum venosum form the vertical inferior parts.
The gallbladder is a pear-shaped organ localized on the right side of the body, directly under the liver. This organ functions to store a digestive fluid called bile until it's needed for digestion.The round ligament of the liver (also called ligamentum teres hepatis) is a remnant of the fetal umbilical vein. This ligament is part of the coronary ligament of the liver.The ligamentum venosum (also called the hepatogastric ligament) is a deep cleft on the posterior surface of the liver. It is a fetal remnant ligament attached to the left branch of the portal vein within the porta hepatis.Learn more in:

Substance A and substance B are mixed together. To separate the mixture, water is added, and substance A is filtered out. Then, the remaining liquid is heated to remove the water, leaving a residue of substance B. Which statement about substance A and substance B could be correct?
Substance A is rice, and substance B is sugar.
Substance A is rice, and substance B is sugar.
Substance A is sugar, and substance B is instant coffee.
Substance A is sugar, and substance B is instant coffee.
Substance A is sand, and substance B is alcohol.
Substance A is sand, and substance B is alcohol.
Substance A is alcohol, and substance B is salt.
The correct answer would be that substance A is rice, and substance B is sugar.
For substance A to be filtered out, it means that A is a water-insoluble substance and for substance B to be recoverable by evaporating off the water, it means that B is water-soluble.
Thus, A can neither be sugar nor alcohol because neither can be recovered by filtration. Also, B can neither be coffee nor alcohol because they can not be recovered as residue through evaporation of water.
Therefore, the only correct answer is that substance A is rice, and substance B is sugar because rice can be filtered out from water while the water-soluble sugar can be recovered by evaporating the water.

Like and opposite charges repel.
Answer:
Like charges repel each other; unlike charges attract.
Explanation:
Like charges repel, and opposite charges attract.
According to Coulomb's law, the force of attraction between two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between the charges.
If the Coulomb's force between two charges is positive, then the force is a repulsive force. This happens between two like charges.
If the Coulomb's force between two charges is negative, then the force is an attractive force. This happens between unlike charges.
