Answer:

higher endurance & adaptability

Explanation:

Genetic Diversity is diversity within species, community.

Genetic Diversity is important as higher genetic variations in population imply that - some or all of their genes have will prove to have higher endurance & adaptability in case of environment aspect (like climate) change or any adversity (new disease).

Answer:

According to Newton's second law of motion, the acceleration of an object equals the net force acting on it divided by its mass, or a = F m . This equation for acceleration can be used to calculate the acceleration of an object when its mass and the net force acting on it are known.

Answer:

the answer is  potassium

Explanation:

Potassium has only one valence electron. ... Whereas, calcium has two valence electrons, so it requires more energy for the removal of a valence electron. Due to this potassium is more reactive than calcium.

Answer:

: A property that is shared by bases and acids is the ability to conduct electricity when dissolved in water. Some ways bases and acids are different is that acids taste sour whereas bases taste bitter. Also, acids but not bases react with metals.

Answer: Beryllium is the fourth element with a total of 4 electrons. In writing the electron configuration for beryllium the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the remaining 2 electrons for Be go in the 2s orbital. Therefore the Be electron configuration will be 1s22s2.

Explanation:

Orbital notation represents an atom of beryllium in the ground state is  [tex]1s^22s^2[/tex].

Beryllium is the fourth element with a total of 4 electrons. Beryllium atoms have 4 electrons and the shell structure is 2.2. The ground state electron configuration of ground state gaseous neutral beryllium is [tex][He] 2s^2[/tex]. The ground state of an electron, the energy level it normally occupies, is the state of lowest energy for that electron. Beyond that energy, the electron is no longer bound to the nucleus of the atom and it is considered to be ionized. Electron configuration for beryllium the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the remaining 2 electrons for Be go in the 2s orbital.

Therefore, the Be electron configuration will be [tex]1s^22s^2[/tex].

Answer:

Explanation:

The original volume can be found by using the formula for Boyle's law which is

[tex]P_1V_1 = P_2V_2[/tex]

Since we are finding the original volume

[tex]V_1 = \frac{P_2V_2}{P_1} \\[/tex]

From the question we have

[tex]V_1 = \frac{3700 \times 0.96}{710} = \frac{3552}{710} \\ = 5.002816...[/tex]

We have the final answer as

Answer/Explanation:

No compounds must be made up of two or more elements. otherwise it wouldn't be a compound. There must be some type of combination or it isn't a compound.

Answer:

a) The heat which we supply to water during boiling is used to overcome these forces of attraction between the particles so that they become totally free and change into a gas. This latent heat does not increase the kinetic energy of water particles and hence no rise in temperature takes place during the boiling of water.

b) Steam produces more severe burns than boiling water even though both are at 100oC because steam contains more heat, in the form of latent heat, than boiling water.

Answer:

(D). Both metallic and ionic compounds can conduct electricity when molten. However, only metallic compounds can conduct electricity in a solid state.

Explanation:

Metallic compound have the ability to conduct electricity. Since they are Metals they have loosely held electrons which can contribute to electricity conduction.

Ionic compound are brittle physically, ionic compound cannot conduct electricity while being in solid state as the ions are held strongly by electrostatic force of attraction, they can only conduct electricity while they are in molten or aqueous state. In molten state they are forming ions, and ions are free to move within the solution and therefore contribute to electricity conduction.

Answer:

The statements that correctly describe chemical reactions are

A. If the reactants include 5 atoms of Fe, then the products must include 5 atoms of Fe.

C. If the reactants include an aluminum atom, then the products must include an aluminum atom.

E. If there are a total of 15 atoms in the reactants, there must be a total of 15 atoms in the product.

Explanation:

In a chemical reaction, reactants are the elements or compounds that react to give a particular product(s). The reactants are the substances that start the chemical reaction and they are found at the left hand side of the chemical equation. While the products are found at the right hand side of the chemical equation and they are seen at the end of the reaction.

In chemical reaction, the number of atoms that starts the reaction remains the same. That is the same number of atoms is seen in the products. This follows the law of conservation of matter - which postulates that matter cannot be created or destroyed.

But in a chemical reaction, number of molecules are not conserved.

The statements that correctly describe chemical reactions are:

A. If the reactants include 5 atoms of Fe, then the products must include 5 atoms of Fe.

C. If the reactants include an aluminum atom, then the products must include an aluminum atom.

E. If there are a total of 15 atoms in the reactants, there must be a total of 15 atoms in the product.

A chemical reaction is a process in which one or more substances, also called reactants, are converted to one or more different substances, known as products. If a physical change occurs, the physical properties of a substance will change, but its chemical identity will remain the same.

Thus, the statements that are true for a chemical reactions are A, C and E.

Answer:

26 protons

A neutral iron atom has 26 protons and 26 electrons. In order to form a 3+ ion, it must lose three electrons. The Fe atom loses two 4s electrons and one 3d electron.

Answer: B - In the past few decades, Carbon dioxide levels has been rising because Rising levels of Carbon dioxide has become an immediate concern for the Environmentalists. This is because carbon dioxide is a greenhouse gas and risen levels of greenhouse gases can lead to unusual warming up of the Earth's Atmosphere.
