Demand in an economy determines the scope for any particular product in the market. Excess demand in an economy leads to higher scope for production increasing investment in that particular product whereas deficient demand leads to lowering investment in that product decreasing production.

Investment demand is sensitive to changes in interest rates; lower rates often encourage more borrowing for capital investments. Businesses assess expected returns on investments through various means, such as forecasts and market analysis, which can directly affect their willingness to invest.

The cell cycle consists of two main phases: Interphase and M phase. Interphase is the preparation phase where the cell grows and gets ready to divide. It includes three parts: G₁ phase (the cell grows and makes proteins), S phase (DNA is replicated so each chromosome has two copies), and G₂ phase (the cell prepares all necessary components for division). The M phase is the division phase and includes four stages: Prophase (chromosomes condense and spindle fibers form), Metaphase (chromosomes align at the cell's center), Anaphase (sister chromatids are pulled apart to opposite poles), and Telophase (nuclear membranes reform and the cell starts to split). This entire process ensures that the daughter cells get the correct amount of genetic material.

The cell cycle consists of 2 main phases; 

1 Interphase - interphase divided into G1,S,G2 phases

(a)-G1 Phase-the cell grows and carries out normal metabolic activities.

(b)-S phase-DNA replication occurs and creating 2 copies of each chromosome.

(c)-G2 phase-the cell continues to grow and prepares for cell division.

M phase (mitosis)-

1 - prophase-chromosomes condense, the nuclear envelope breaks down and the spindle apparatus begins to form.

2- Metaphase- chromosomes align at the cell's equator and attached to spindle fibers.

3-Anaphase-sister chromatids separate and move towards opposite poles of the cell.

4-Telophase-chromosomes arrive at the poles and the nuclear envelope reforms and the cell  begins to pinch in preparation for division.

Cytokinesis - the cytoplasm divides and resulting in 2 daughter cells.

Valency of Carbon: The valency of carbon is 4. This means carbon can form four covalent bonds with other atoms (including other carbon atoms) by sharing its four valence electrons.

Property Leading to Long-Chain Compounds: The property of carbon that enables it to form long-chain compounds is catenation. Catenation is the ability of carbon atoms to bond with one another through strong covalent bonds, forming stable chains, rings, or branched structures. This is due to:

• High bond strength of carbon-carbon (C-C) bonds.
• Tetravalency, allowing carbon to form multiple bonds (single, double, or triple) with other carbon atoms or elements like hydrogen, oxygen, or nitrogen.
• Small atomic size, which supports strong covalent bonding.

This unique ability results in the formation of diverse organic compounds, such as hydrocarbons, polymers, and complex molecules like proteins and DNA.

Valency of carbon is 4 and catenation property of carbon leads to forming long chain compounds
