1. Three Layers of the Eye
Outermost layer (Fibrous tunic)
-
Sclera: tough white outer coat; protects and maintains shape
-
Cornea: transparent front; main structure that bends (refracts) light
Middle layer (Vascular tunic / Uvea)
-
Choroid: rich in blood vessels; nourishes retina and absorbs stray light
-
Iris: colored part; controls pupil size
-
Ciliary body: contains muscle that changes lens shape for focusing
Innermost layer (Neural tunic)
-
Retina: contains rods & cones; converts light

Q1. Short Notes (5 Marks each)
🔹 Alloys of Copper
Copper alloys are formed by mixing copper with other metals to improve strength, corrosion resistance, and workability.
-
Brass (Cu + Zn)
-
Good corrosion resistance, ductile
-
Used in fittings, sheets, decorative items
-
-
Bronze (Cu + Sn)
-
Harder and stronger than brass
-
Used in bearings, statues
-
-
Gunmetal (Cu + Sn + Zn)
-
Resistant to corrosion and wear
-
Used in valves, pipes
-
-
Cupronickel (Cu + Ni)
-
High resistance to seawater corrosion
-

Ένα τέτοιο μόριο είναι το εντομοκτόνο DDT. Αν, για παράδειγμα, μια κάμπια φάει φύλλα φυτού που έχει ραντιστεί με DDT, αυτό θα απορροφηθεί από τον οργανισμό της, αλλά, επειδή δε μεταβολίζεται και δε διασπάται, θα συσσωρευτεί στους ιστούς της και φυσικά δε θα αποβληθεί με τις απεκκρίσεις...

fasi del dubbio
- dubbio sulla testimonianza dei sensi:
Riprende uno degli argomenti tradizionali dello scetticismo. In alcuni casi i sensi ci ingannano, e sembra ragionevole dubitare in generale delle sensazioni in quanto in
qualche situazioni si siano rivelate fallace. La scarsa attendibilità della conoscenza sensibile inoltre é dimostrata dal fatto che non distinguiamo sogni e realtà.

Population vs Sample
-
Population: The entire group you want to study.
Example: All students at UTM. -
Sample: A subset of the population used to make conclusions.
Example: 100 UTM students surveyed in the library. -
Population parameter: The true value in the population.
Example: The actual percentage of all UTM students who

1. Short note on String.
A String is a one-dimensional array of characters terminated by a null('\0'). Each character in the array occupies one byte of memory, and the last character
must always be null('\0'). The termination character ('\0') is important in a string to identify where the string
ends. Syntax: charstring_name[size];
char name[10]; [0] [1] [2] [3] [4] [5] [6] [7] [8] [9]
