It can be speculation of any assumption which need to be proved.
Further more an ideal theory must be an authoritative principle, which is a result of continuous observation, proper examination, analysis logically accurate explanation of a specific phenomenon.
The characteristics for ideal theory are, it must possess the quality and authenticity.
A wide acceptance by people and the quality should be evaluated correctly.
It must solve the problems potentially and expert verified, confirmed hypothesis.

If an element contains six electrons, how many will be placed in the second valence shell?
A. 8
B. 4
C. 2
D. 6
Answer:
A. 8
Explanation:
The 2s subshell holds a maximum of 2 electrons, and the 2p subshell holds a maximum of 6 electrons. Which means that the second shell can hold a maximum of only 8 electrons (2+6 = 8)
A magnetic field protects Earth from the Sun's high-energy particles. What two processes are involved in the formation of Earth's magnetic field? The movement of materials in Earth's mantle and Earth's rotation the movement of metals in Earth's core and Earth's rotation the movement of solar wind toward Earth and Earth's revolution the movement of eruptions from the Sun's surface and Earth's revolution
Answer:
B.) The movement of metals in Earth's core and Earth's rotation
Explanation:
got a 100 on the Test
The two processes that are involved in the formation of Earth's magnetic field are the movement of metals in Earth's core and Earth's rotation. The correct option is B.
What is a magnetic field?A magnetic field is a place near a magnet in which a physical field is created with the electric charge. The field applies a great force on the other objects which come into this physical field.
Earth's core is the center point of earth, which is in a molten state and contains a high amount of iron. The core of the earth maintains the revolving of the earth as it is attracted by a magnetic field.
Due to gravitational force, the earth rotates on its axis and around the sun. Earth takes around 24 hours to revolve on its axis and 365 days in revolving around the sun.
Thus, the correct option is B. the movement of metals in Earth's core and Earth's rotation.

Why is the shape of a protein so important?
Answer:
The shape of a protein is important because it determines whether the protein can interact with the other molecules.Which statement best represents how structure relates to function? a. Some insects live longer than others. b. Many tropical birds can be taught to speak. c. Great white sharks have sharp serrated teeth for tearing into their prey. d. horse's mane is often black.
Answer:
C. Great white sharks have sharp serrated teeth for tearing into their prey.
Explanation:
I took the quiz.
Adaptation is the evolutionary process that allows the natural selection of the species. Great sharks having sharp teeth for tearing into prey are structures related to functions. Thus, option c is correct.
What is adaptation?Adaptation has been defined as the mechanism by which biological species adjust themselves to the changes in the environment around them in an ecosystem. This leads to the evolution of the structures and functions.
The sharp teeth structures of the white shark allow them the function of catching their prey in the ocean ecosystem. These structures were adapted for the survival of the species and to catch food.
Therefore, option c. the sharp teeth of great white sharks are the adapted structures that allow them to catch prey.

Describe the importance of water being a polar molecule.
Answer:
Because of water's polarity it can dissolve other polar substances very easily. Basically, when a polar substance is put in water, the positive ends of its molecules are attracted to the negative ends of the water molecules, and vice versa. This attraction causes the the molecules of the other substance to mix with the water.

What activation energy was used to start the chemical reaction in the burning marshmallow?
Answer:
This question is incomplete
Explanation:
This question is incomplete. However, let's understand some terms
Activation energy is the minimum amount of energy required for a reaction to proceed. Under normal condition, when the activation energy is high, it takes longer for the reaction to proceed than when it is low.
The burning of marshmallow is an exothermic reaction as it involves the transfer of heat energy into the environment.

hydrogen and oxygen come pouring out it drips and it dribbles and it comes from a spout
Answer:Water
Explanation:
This looks like a proverbial question, so I'll try and answer it as best as I can
Th mixture of 'hydrogen and oxygen came pouring out' to give water. Water is a liquid that 'drips and dribbles and it comes poring from a spout'
The question is talking about the reaction between hydrogen and oxygen to give water; a form of liquid as the by-product.
The reaction involves one atom of oxygen reacting with two atoms of hydrogen with an hydrogen bonding in-between to give a molecule of water.
Also note that a spout is a stream of liquid issuing from somewhere with great force. So the answer is water.

Below are the seven properties of water that make life possible on Earth. Describe five of these properties and provide an example of each: Hydrogen bonding, cohesion and adhesion, surface tension, heat of vaporization, specific heat, density, and universal solvent
Answer:
Properties of water are given below.
Explanation:
Hydrogen bonding is an important bond which occurs between two water molecules which make them sticky due to partial positive charge on hydrogen and partial negative charge on oxygen. Cohesion and adhesion occurs due to the attraction of partial positive and partial negative charges of hydrogen and oxygen atom. Density of water increases with the decrease in temperature and maximum at 4 degree Celsius and after further decrease in temperature, decrease in density occurs which is a unique property of water. water is a universal solvent because a large amount of solutes can be dissolved in it. Heat of vaporization refers to the amount of heat required to transform liquid into vapors.Water has a heat of vaporization about 40.65 kJ/mol.
