## Economic Principles Overview:
### 1. Opportunity Cost:
- *Definition*: The value of the next best alternative foregone when making a decision.
- *Example*: If you spend ₹100 on a movie ticket, the opportunity cost is what else you could have bought with that ₹100.
### 2. Marginal Principle:
- *Definition*: Decisions are made based on the additional (marginal) benefits and costs of an action.
- *Example*: Produce more units of a product until marginal revenue equals marginal cost.
### 3. Incremental
Q1:
An example of a third class lever is knee extension (like kicking a ball), where the force is between the fulcrum and load. The knee joint is the fulcrum (pivot point where the lower leg rotates), the quadriceps tendon inserting on the tibial tuberosity provides the effort in the middle, and the leg and foot (plus any ball) form the load at the far end.
Q2:
Gymnasts bend their knees and flex their hips when they land so their legs act like shock absorbers, increasing the time over which
Aristotle is called the father of political science because he studied politics through observation and practical reasoning. He believed that humans are political beings who can achieve their highest moral and intellectual development only within the state, whose purpose is to promote the good life. His justification of slavery was based on the idea of natural slavery, where some people lacked rational capacity and therefore benefited from being ruled, reflecting Greek social conditions. Aristotle’s

Formas de interpretação
A interpretação jurídica consiste em determinar o verdadeiro sentido e alcance de uma norma. Essa interpretação pode assumir diversas formas, dependendo da relação entre o texto literal e o espírito da lei. Entre as formas principais destacam-se:
Interpretação declarativa – o significado literal coincide com a intenção da lei; o intérprete apenas esclarece o sentido natural das palavras.
Interpretação extensiva – alarga-se o sentido literal para corresponder
Direct Materials and Labor: Materials price variance = (AP - SP) x AQ \\ Materials Quantity Variance = (AQ - SQ) x SP \\ Materials Spending Variance MPV + MQV \\ Labor Rate Variance = (AR-SR) x AH \\ Labor Efficiency Variance = (AH - SH) x SR \\ Labor Spending Variance = LRV + LEV \\
Standard Hours and Cost: Standard Hours Allowed = standard hours per unit x actual output \\ standard cost allowed = SQ x SP or SH x SR
Variable and Fixed Overhead: VOH Spending Variance = AVOH - (AH x SR)
...Female (Ovary – Germarium):
In the Drosophila ovary, 2–3 germline stem cells (GSCs) are located at the anterior tip of the germarium. They physically attach to cap cells using E-cadherin–mediated adhesion. Cap cells act as the niche, producing key signals such as Dpp, Gbb, Hedgehog, and Piwi to maintain GSC self-renewal.
When a GSC divides, it undergoes asymmetric division: one daughter remains attached to cap cells and stays a stem cell, while the other daughter moves away from the niche
