Thermal energy “flows” from warmer areas to colder areas. Heat is a measure of this flow.
True or False
Answers
Answer:
True
Explanation:
Throughout the universe, it's natural for energy to flow from one place to another. And unless people interfere, thermal energy — or heat — naturally flows in one direction only: from hot toward cold. Heat moves naturally by any of three means. The processes are known as conduction, convection and radiation.
The statement, "Thermal energy “flows” from warmer areas to colder areas. Heat is a measure of this flow" is true.
What is thermal energy?The energy created by heat is referred to as thermal energy. It is created when a body's temperature rises. As a result, the molecules, and atoms start to sprint, move quickly, or crash into one another.
When a substance's temperature rises, heat, a type of energy, is created. Temperature, thermal energy, and heat all relate to one another. Heat always moves from a hot body to a cold body.
The heat or thermal energy in the body increases as the temperature rises, causing the movement of the atoms to accelerate and the atoms to collide. Heat is a variable of thermal energy.
Thus, the statement is true.

Which type of selection is shown in the graph above?
A. Disruptive selection
B. Stabilizing selection
C. Disaster Selection
D. Directional selection
Answers
In the given graph, the Evolved Population is showing disruptive selection. Hence, the correct option is A. Disruptive selection.
Stabilizing selection is a form of natural selection where individuals with average phenotypes are more likely to survive and reproduce their number. In this selection, the population tends to maintain a stable phenotype. As shown in the graph, the population is maximum for the population having a moderate length of neck.
Disruptive selection is a type of natural selection where extreme phenotypes are preferred over average phenotypes, leading to an increase in genetic variation and the population becoming more diverse. In this type of selection, the population diverges into two or more distinct phenotypic groups. As shown in the graph, two ranges of the population are favored for having traits for extreme lengths of the neck.

When a chemical reaction does not occur, what happens to the atoms of the two substances? Provide an example from Sim as evidence to support your answer.
Answers
An example of this can be seen in the Sim on Amplify, where students can experiment with different chemical reactions. For instance, in the "Chemical Reactions" Sim, students can explore the reaction between iron and sulfur to form iron sulfide. In this reaction, the iron atoms and sulfur atoms combine to form a new compound, iron sulfide, with different properties than the original iron and sulfur. The atoms of the iron and sulfur are rearranged to form new bonds, resulting in the formation of a new substance. This is an example of a chemical reaction, where the atoms of the two substances are rearranged to form a new compound with different properties.
Answer:
Explanation:A chemical response is a chemical transformation in which two chemicals combine to create a third component.
(i) Adding diluted acid to an active metal causes the test tube to heat up and hydrogen gas to escape, which results in the production of heat.
(ii) When diluted hydrochloric acid is added to silver nitrate, AgCl, a white precipitate, results.
(iii) When water is added to quicklime, the mixture boils and produces heat along with a hissing sound.
(iv) Thermal breakdown of mercury oxide - Mercury turns from red to a metallic silver tint as a result of this process.

Answer: The equilibrium constant expression for the given system is \(K_{eq}=\frac{[CO_2]}{[O_2]}\)
Explanation:
Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric coefficients. It is represented by \(K_{eq}\)
For a general chemical reaction:
\(aA+bB\rightarrow cC+dD\)
The \(K_{eq}\) is written as:
\(K_{eq}=\frac{[C]^c[D]^d}{[A]^a[B]^b}\)
The concentration of pure solid and pure liquid are taken as 1 in equilibrium expression.
The \(K_{eq}\) for the given reaction is written as:
\(C(s)+O_2(g)\rightarrow CO_2(g)\)
\(K_{eq}=\frac{[CO_2]}{[O_2]}\)

In an electrical wire, if instead of copper, plastic wire is used. Would it conduct electricity?Justify your answer.
Answers
Answer:
No, a plastic wire would not conduct electricity. This is because plastic is an insulator that does not allow electric current to flow through it. In a wire, electrical conductivity is provided by the movement of charged particles - typically, electrons. Copper is an excellent conductor of electricity because it has a high number of free electrons that are not bound to atoms and can move through the wire very easily. However, in a plastic wire, the tightly bound electrons of its atoms do not allow for the free flow of charges, thus preventing the passage of electric current.

Ionic and covalent bonds help arrange atoms into unique structures for proteins like hemoglobin. Why is this necessary?(1 point)
Answers
Answer:
Ionic bonds can be important to protein structure because they are potent electrostatic attractions. In the hydrophobic interior of proteins, ionic bonds can even approach the strength of covalent bonds
Covalent bonds in amino acids are useful to stabilize the structure of the proteins and their interactions. The ionic bond formed as the atoms in amino acids with opposite charges accompanied strong electrostatic attractions.
What types of bonds are involved in protein structure?Proteins are 3D structures of amino acids that are further made of an amine and a carboxyl group, and are arranged in specific structures in four levels to give rise to the complete protein molecule.
Proteins can be described as the polymers of polypeptides which are structured by arrangements of these chains in a three-dimensional structure. They are folded and are driven by special non-covalent interactions such as peptide bonds, ionic bonds, hydrogen bonds, Van der Waals interaction, and disulfide bridges.
The primary structure is the sequence of amino acids through peptide bonds to form a polypeptide chain. The secondary structure is a sub-structures made by hydrogen bonding between the main chain peptide groups on the polypeptide backbone chain.
Tertiary structure is the 3D arrangement of protein in which α and β helices are folded into a globular structure with the interactions such as hydrogen bonds, salt bridges, disulfide bonds, and tight packing of side chains.
