1. What is Double Fertilization?
Answer: Double fertilization is a characteristic feature of angiosperms. In this process, two male gametes are involved in fertilization. One male gamete fuses with the egg cell to form a diploid zygote (syngamy). The other male gamete fuses with two polar nuclei to form a triploid primary endosperm nucleus (triple fusion). Thus, two fusions occur in the same embryo sac, so it is called double fertilization.
2. What is Triple Fusion?
Answer:
Q: What is the difference between if, elif, and else?if checks a condition. elif checks another condition if the previous one is false. else runs if none of the conditions are true.
Q: When do we use a for loop instead of while?
We use for when we know the number of iterations. while is used when the condition controls the loop.
Q: What is an infinite loop?
A loop that never stops because its condition is always true.
Q: What is a function?
A reusable block of code that performs a specific task.
Q:
Biodiversity.
1. Give an example of invasive weed species that threatens our native species?
Answer:- Parthenium hysterophorus (Congress grass) or Eichhornia crassipes (Water hyacinth).
2. Write the equation of Species–Area relationship in logarithmic scale?
Answer:- log S = log C + Z log A
Where S = number of species, A = area, C and Z = constants.
3. Write scientific name of water hyacinth.?
Answer: Eichhornia crassipes
4. What is ex-situ conservation?
...Reproductive health
1. Why Cu-T acts as an effective contraceptive?
Answer: Cu-T releases copper ions which reduce sperm motility and prevent fertilization. It also prevents implantation in the uterus.
2. What do you understand by reproductive health?
Answer: Reproductive health means a healthy reproductive system and the ability to reproduce safely without disease or complications.
3. What substances are present in semen?

...You must memorize these for exams:
• Laissez-faire policy (no government intervention)
• Supply creates its own demand (Say’s Law)
• Full employment
• Money is neutral
• Flexible wages, prices, interest rates
• Long-run focus
The Classical Model of income and employment determination was developed by Adam Smith and other classical economists. It assumes laissez-faire policy, full employment, flexible wages and prices, and neutrality of money.

Q1. Explain Time Series Forecasting Methods and Compare Naïve, Moving Average, Weighted Moving Average and Exponential Smoothing.
Time Series Components: Trend T, Seasonality S, Cyclical C, Random R
Naïve Method: Fₜ₊₁ = Aₜ
Assumes next demand equals last demand
Used as benchmark
Simple Moving Average (n): Fₜ₊₁ = (Aₜ + Aₜ₋₁ + … + Aₜ₋ₙ₊₁) / n
Smooths random variation
Higher n increases lag
Weighted Moving Average: Fₜ₊₁ = w₁Aₜ + w₂Aₜ₋₁ + … + wₙAₜ₋ₙ₊₁

Control Limits:
UCL = μ + 3σ
LCL = μ − 3σ

Cost of Quality = POC + PONC
POC = Prevention + Appraisal
PONC = Internal failure + External failure
