The correct answer is False
Explanation:
A limiting factor refers to a condition that stops or limits the growth of a population of any species. Some of these factors include the availability of sources such as food, shelter or water; predation; natural weather conditions; natural disasters; and competence.
The previous idea implies food is not the only factor or condition that would stop or limit the growth of a population but there are many other factors that could prevent a population from growing too large, this includes abiotic factors (nonliving condition) such as weather and biotic factors (living condition) such as competition with other species or individuals or predation.
Food is not the only limiting factor that keeps populations from growing too large. This statement is false.
Populations are regulated by a variety of factors, including but not limited to food availability. These factors can be categorized into two main types: density-dependent and density-independent factors.
Density-dependent factors are influenced by population size and include factors such as competition for resources (including food), predation, disease, and territoriality.
As a population grows, competition for limited resources, including food, increases. This can lead to reduced growth, increased mortality, and ultimately limit the population's size.
Thus, while food availability is an important factor in population dynamics, it is not the sole limiting factor. Other ecological factors and interactions within the ecosystem play significant roles in regulating population size and preventing populations from growing too large.

Hydroxide Ions
Acid and Bases are defined according to three different theories and concepts.
A) Arrhenius Concept
B) Lowry Bronsted Theory
C) Lewis Theory
According to Arrhenius Concept of Acid and Base, "Acid is any specie which when dissolved in water ionizes to produce H⁺ ions".
Examples:
HNO₃ → H⁺ + NO₃⁻
H₃PO₄ → 3 H⁺ + PO₄³⁻
While, "Bases are those species which when dissolved in water produces Hydroxyl Ions (OH⁻)".
Examples:
KOH → K⁺ + OH⁻
Ca(OH)₂ → Ca²⁺ + 2 OH⁻
When an Arrhenius base dissolves in water, it yields hydroxide ions (OH-).
When an Arrhenius base is dissolved in water, it yields hydroxide ions, which have a chemical formula of OH-. The formula for an Arrhenius base is usually represented as BOH, where B represents a cation (positive ion) and OH- represents the hydroxide ion. Some examples of Arrhenius bases include sodium hydroxide (NaOH) and potassium hydroxide (KOH).

(2) They differ in their properties, only.
(3) They differ in their molecular structure and properties.
(4) They do not differ in their molecular structure or properties.
Answer: Option (3) is the correct answer.
Explanation:
When an element exists in two or more different physical forms then they are known as allotropes.
For example, diamond and graphite are both allotropes of carbon.
In graphite, carbon atoms are joined together in sheets of six sided lattice. Whereas in diamond, carbon atoms are joined together in four cornered lattice.
Therefore, as these allotropes are made up of same element so they have similar chemical properties but different physical properties like melting point, boiling point etc.
Also, both of them have different molecular structure.
Thus, we can conclude that the statement the differ in their molecular structure and properties correctly describes diamond and graphite.
Answer:
The inert pair effect is the tendency of the two electrons in the outermost atomic s-orbital to remain unshared in compounds of post-transition metals. The term inert pair effect is often used in relation to the increasing stability of oxidation states that are two less than the group valency for the heavier elements of groups 13, 14, 15 and 16. .[1] The name suggests that the outermost s electrons are more tightly bound to the nucleus in these atoms, and therefore more difficult to ionize or share
