Describe how light intensity, CO₂ concentration and temperature affect the rate of photosynthesis.
Point: Photosynthesis rate increases as light, CO₂, and temperature increase—up to an optimum. Explain: Light provides energy for the reaction. CO₂ is a substrate for glucose synthesis. Temperature affects enzyme activity in chloroplasts. Example: In experiments, rate of oxygen release (or CO₂ uptake) rises with light until plateau; same with CO₂ & temp. Evaluate: If one factor is limiting,...

1. Relational Model Basics
Key Concepts:
A relation is a set of tuples (no duplicates, no ordering)
Each tuple conforms to the relation's schema
Primary keys uniquely identify tuples
Foreign keys maintain referential integrity
Practice Question: Consider a library database with Books(ISBN, title, author, year). Which statement is true?
a) Two books can have the same ISBN if they're different editions
b) The order of book records affects query results
c) Each book record must conform to the (ISBN, title,...
Vision describes a desirable long-term future (includes BHAG + vivid description).
Mission defines the organization's purpose; Values outline guiding principles.
These components form a "core ideology", providing stability in turbulent environments and direction for change.
Despite potential, many statements are met with cynicism due to misalignment between rhetoric and reality.
Statements should not be PR-driven;
Since, the fluid is incompressible, A₁Δx₁ = A₂Δx₂ = ΔV
The work done on the fluid is due to the pressure of fluid,
Therefore, The work done, ΔW = F₁Δx₁ - F₂Δx₂
= P₁A₁Δx₁ - P₂A₂Δx₂
= P₁ΔV - P₂ΔV
ΔW = (P₁ - P₂) ΔV
Change in kinetic energy, KE = KE2 - KE1
= ½ mv₂² - ½ mv₁²
ΔKE = ½ m (v₂² - v₁²)
= ½ ρΔV (v₂² - v₁²)
Change in potential energy, ΔPE = PE2 - PE1
= mgh₂ - mgh₁ = mg (h₂ - h₁)
ΔPE = ρg (h₂ - h₁)

PARAMAGNETISM
The atoms of paramagnetic substances possess permanent magnetic dipoles. In the absence of external magnetic field, the atomic dipoles are distributed randomly throughout the paramagnetic material as shown in fig. (5.6a). The external field of individual atoms cancel each other's effect and hence do not exhibit any magnetic properties in the absence of external magnetic field.
Now, when the substance is subjected to an external field B, each of the atomic dipole experiences a torque.
What to write on cheat sheet:
To find what n must be:
n >= (Z1-a/2 ) / MOE) ^2 * p(1-p)
Wald CI Interval:
Sp^ = sqrt((p^ * (1 – p )) / n )
Odds Ratio:
Calculated by criss cross of 2x2 table
The odds forsomeone to smoke >= 5 cigarettes and have lung cancer is 3.40 times that of
someone whosmokes < 5 cigarettes dailyto have lung cancer.
Fishers Test:
For when cell frequencies are < 5. 2x2 table. Tests for independence
H0: odds ratio = 1
HA: odds ratio != 1
