Which best describes a diagram of evolution? A.a straight line B.a crooked line C.a diagonal line D.a bush (explain how)

Answers

Answer 1

Answer:

Answer:

The best description would be a bush.

Explanation:

Evolution resembled a tree, with a trunk branching off into different branches, which branch off into smaller branches, etc. This is basically the same as a bush. Any kind of line that's just a line, without any branching out, doesn't properly represent evolution because it only follows one line of evolution instead of accounting for the full picture.

Classify the chemical equations as being balanced or not balanced

Answers

Answer: Two of them are balanced and two of them are unbalanced.

Explanation:

A balanced chemical equation is defined as the equation in which total number of individual atoms on the reactant side is equal to the total number of individual atoms on the product side. These equations follow law of conservation of mass.

An unbalanced chemical equation is defined as the equation in which total number of individual atoms on the reactant side is not equal to the total number of individual atoms on the product side. These equations does not follow law of conservation of mass.

For the given chemical equations:

Equation 1: $2CO+2NO\rightarrow 2CO_2+N_2$

As, number of carbon, nitrogen and oxygen atoms on the reactant side is equal to the number of carbon, nitrogen and oxygen atoms on the product side. Thus, this is a balanced chemical equation.

Equation 2: $6CO_2+6H_2O\rightarrow C_6H_(12)O_6+O_2$

As, number of oxygen atoms on the reactant side is not equal to the number of oxygen atoms on the product side. Thus, this is not a balanced chemical equation.

Equation 3: $H_2CO_3\rightarrow H_2O+CO_2$

As, number of carbon, nitrogen and oxygen atoms on the reactant side is equal to the number of carbon, nitrogen and oxygen atoms on the product side. Thus, this is a balanced chemical equation.

Equation 4: $2Cu+O_2\rightarrow CuO$

As, number of oxygen and copper atoms on the reactant side is not equal to the number of oxygen and copper atoms on the product side. Thus, this is not a balanced chemical equation

Hence, two of the equations are balanced and two are unbalanced.

1,2,4 are not balanced, 3 is balanced

Why is the structure of molecule important to its function?

Answers

Answer:

In materials of molecular structure, the nature of intermolecular and intramolecular bonds has a decisive influence on their characteristics and properties. Characteristics such as melting and boiling points, mechanical strength and hardness depend on the type of such bonds.

A Molecule's Biological Function is Related to its Shape. Each molecule has a characteristic size and shape that determines its function in the living cell. The shapes of molecules are determined by the positions of the atoms' orbitals. When an atom forms covalent bonds, the orbitals in its valence shell are rearranged that’s your answer

In a model of Earth's layers that is determined by physical properties, how might the atmosphere be classified? Would it be part of the lithosphere or a seperate layer?

Answers

Generally, the Earth is divided into spheres which include the "lithosphere" (land), "hydrosphere" (water), "biosphere" (living things), and "atmosphere" (air). The earth is divided into three layers based on chemical composition and these are the core, mantle and crust. In addition, the earth is also divided into physical properties which include lithosphere, athenosphere, mesosphere, outer core and inner core. Based on the given details, we can conclude that the atmosphere cannot be part of the lithosphere but instead, it is classified in a separate layer. The lithosphere only consists the outermost, rigid part of the Earth, which are the crust and the mantle. Hope this answer helps.

A 10kg bowling ball would require what force to accelerate down an alleyway at a rate of 3m/s2?

Answers

Ok so this all boils down to Newton's second law

Force = mass X acceleration

so the force = 10 X 3 = 30N
