The solid piece of ice would break more easily than that of the solid piece of copper metal because ice can be broken more easily than copper metal. The affinity is stronger in metals than water.
What are pure substances?Pure substances can be defined as the substances which are made up of only one type of atom or only one type of molecule such as water. All the constituent particles of a substance are the same in their chemical nature and physical properties. For example, the elements and compounds.
Matter is a substance which can be broken down into two categories: pure substances and mixtures. Pure substances are further broken down into elements and compounds which are similar. A chemical substance is composed of only one type of atom or molecule. However, a mixture is composed of different types of atoms or molecules which are not chemically bonded to each other. The chemical bonds are stronger in copper metal than that of ice. That's why, it is easier to break apart ice than copper metal.

Answer:
Explanation:
Catalyst is a substance that influences the reaction but does not participate in the reaction
Answer:
Catalyst is a substance that influences the rate of reaction without being consumed in the reaction.
-They increase the rate of reaction by decreasing the activation energy of the reaction.
-As they are not used up in the reaction they are required in a small quantity.
-In biological system, enzymes are referred to as biological catalyst or biocatalyst. They are generally protein in nature and are very specific for their substrate. They also increases the rate of biological reaction by forming enzyme-substrate complex.
-Few examples of catalyst are: potassium permagnet, platinum, enzyme (like hexokinase, hydrolase etc) etc.

D.cell wall
A cell is the fundamental, structural, and functional unit of all living things. Plant cells do not have lysosomes or centrosomes, whereas animal cells do (or a pair of centrioles).
What is Plant cells?A plant cell is a eukaryotic cell with a true nucleus and organelles that perform specific functions. However, some organelles found in plant cells differ from those found in other eukaryotic cells. Organelles, cytoplasmic structures, cytosol, cell membrane (also known as plasma membrane), and cell wall are all components of a typical plant cell structure.Plastids, nucleus, mitochondria, endoplasmic reticulum, and Golgi apparatus are plant cell organelles. The plant cell is the fundamental unit of all plants. Plant and animal cells are both eukaryotic, which means they have a membrane-bound nucleus and organelles.

Predict what would happen to the H+ ion concentration if you added sulfuric acid to water. Would the pH increase or decrease
When a sulfuric acid is dissolved in water, hydrogen ions are produced, increasing the concentration of hydrogen ions in the solution. Result in decrease in pH of solution.
What is PH solution?Indicating the acidity or basicity of a solution, the pH of a solution measures the molar concentration of hydrogen ions in the solution.
The acronym pH stands for “power of hydrogen,” and the pH value in numbers is simply the negative of the molar concentration of H+ ions divided by 10.
A solution's acidity can be determined by looking at its pH, which is a measurement of hydrogen ion concentration.
Pure water slightly separates into ions with roughly equal amounts of hydrogen and hydroxyl (OH) ions.
Nutrient availability, biological processes, microbial activity, and chemical behavior can all be influenced by pH.
Therefore, if you added sulfuric acid to water, pH decrease.

According to the scientific theory of atoms, which of the following statements best describes the location of electrons? A. in the nucleus of the atom B. both in the nucleus and around it C. outside the nucleus and often far from it, in the electron cloud D. outside the nucleus, yet very near it because they are attracted to the proton
Answer:
D. Outside the nucleus, yet very near it because they are attracted to the proton
Explanation:
Electrons are located outside of the nucleus of the atom, which is made up of neutrons and protons. In physics, the space they take up is informally referred to as the electron cloud. Protons and electrons are attracted to each other, because the positive electric charge of the protons is attracted to the negative charge of the electrons. This is why the electrons are very close to the nucleus.
The best statement that describes the location of electrons is D whichis Outside the nucleus, yet very near it because they are attracted to the proton.
What is electron?An electron is a negatively charged subatomic particle. It can be either free , or bound to the nucleus of an atom.
Electrons in atoms exist in spherical shells of various radii, representing energy levels. The larger the spherical shell, the higher the energy contained in the electron.
Thus, option "D" is correct.

Answer: well see if a trait is dominant you are more likely to have said trait if a trait is recessive you are less likely to have said trait
Explanation:
Answer:
dominance is the one that will be seen in a creature, recessive traits will not be seen, but can still be passed on
Explanation:
if both parents pass on the same recessive gene then their child will show that trait, such as two sets of parents, one dark skinned and one light skinned, their children will be dark skinned, but if their children have a child is has a chance of having light skin because they both carry that recessive trait.

A) Primary Pollutant
B) Smog
C) Air Pollution
D)Secondary Pollutant
A pollutant that forms in the atmosphere by chemical reaction with primary air pollutants, natural components in the air, or both is a primary pollutant. The correct option is A).
What are primary pollutants?Airborne primary contaminants are introduced directly. They consist of heavy metals, volatile organic compounds (VOCs), particulates, nitrogen oxides, sulfur oxides, and carbon oxides.
Primary pollutants result in secondary pollutants. They consist of chemical evaporation, ground-level ozone, and photochemical smog.
A pollutant with a natural origin is one that was produced by elements found in nature, such as ozone produced by photochemistry, sea salt particles, volcanic dust, and fibers from trees, among others.
Therefore, the correct option is A) Primary Pollutant.

5. Describe logistic growth and exponential growth.
Answer:
Population Growth Form: The graphic pattern obtained when a population growth is plotted against time is called population growth form or model. There are two types namely: Exponential J-shaped and Logistic or S-shaped.
J-shaped or Exponential Growth Form: At any point of time, population size does not reach the equilibrium.
Explanation:
When resources are limited, populations exhibit logistic growth. In logistic growth, population expansion decreases as resources become scarce.
