❖ Substances that absorb or emit light discontinuously in the form of small packets or bundles.

❖ The smallest packet of energy is called quantum (plural quanta).

❖ The radiation is propagated in the form of waves.

❖ The energy of a quantum is directly proportional to the frequency of the radiation

E ∝ v
E = hv
E = (hc)/ λ =hc v

Where E = Energy of radiation
h = Planck's constant
= 6.626 * 10^-27 * erg .sec
= 6.626 * 10^-34 Joule.sec

❖ A body that can absorb or emit energy in whole number multiple of quantum.

E = nhv

Where n = 1, 2, 3, 4

❖ The frequency of emitted radiation goes from lower to higher as the temperature increases.

The four valves in order of circulation are:

1. Tricuspid Valve

Has three leaflets or cusps.

Separates the top right chamber (right atrium) from the bottom right chamber (right ventricle).

Prevents the back flow of blood from the right ventricle to the right atrium.

2. Pulmonary Valve (or Pulmonic Valve.

Has two leaflets.

Separates the right ventricle from the pulmonary artery.

Prevents the back flow of blood from the pulmonary artery to the right ventricle.

3 . Mitral Valve

Has two leaflets.

Separates the top left chamber (left atrium) from the bottom left chamber (left ventricle).

Prevents the back flow of blood from the left ventricle to the left atrium.

4. Aortic Valve

Has three leaflets, unless it's abnormal from birth

Separates the left ventricle from the aorta.

Prevents the backflow of blood from the aorta to the left ventricle.

MORPHOLOGY

►► The skin is smooth and slippery due to the presence of mucus. The skin is always maintained in a moist condition.
►► The color of dorsal side of body is generally olive green with dark irregular spots. On the ventral side, the skin is uniformly pale yellow

►► The frog never drinks water but absorbs it through the skin.

►► Body of a frog is divisible into its head and trunk. A neck and tail are absent

►▸ Above the mouth, a pair of nostrils is present. Eyes are bulged and covered by a nictitating membrane that protects them while in water.

►►On either side of the eyes, a membranous tympanum (ear) receives sound signals.

►►The forelimbs and hind limbs help in swimming, walking, leaping and burrowing.

►►The hind limbs end in five digits and they are larger and muscular than forelimbs that end in four digits. Feet have webbed digits that help in swimming.

Cytokinesis

✱ Cytokinesis completes the process of cell division.

✱ Cytokinesis is the process in which the cell actually divides into two. With the two nuclei already at opposite poles of the cell, the cell cytoplasm separates, and the cell pinches in the middle, ultimately leading to cleavage.

✱ The two cells formed are roughly equal in size.

✱ The process of cytokinesis is different in animal and plant cells.

✱ In an animal cell, cytokinesis is achieved by the appearance of a furrow in the plasma membrane.

✱ The furrow gradually deepens and ultimately joins in the centre dividing the cell cytoplasm into two.

✱ Plant cells are enclosed by a relatively inextensible cell wall, therefore, they undergo cytokinesis by a different mechanism.

✱ The formation of the new cell wall begins with the formation of a simple precursor, called the cell-plate that represents the middle lamella between the walls of two adjacent cells.

✱ In some organisms, karyokinesis is not followed by cytokinesis as a result of which multinucleate condition arises leading to the formation of syncytium (e.g., liquid endosperm in coconut)

Biotechnology Application

NEET PYQS

Pest Resistant Plants

✓Nematode Meloidegyne incognita
infects the Roots of Tobacco plants.

✓Novel strategy was adopted to prevent
this infestation which was based on
the process of RNA Interference (RNAi)

✓RNAi takes place in all Eukaryotic
Organisms as a method of Cellular
Defence

✓RNAi involves silencing of a specific
mRNA
(Due to a complementary ds-RNA
molecule that binds to and prevents
translation of the mRNA/Silencing)

✓Mobile Genetic Elements (Transposons)

Interpretation of balanced chemical equations:

Once we get a balanced chemical equation then we can interpret a chemical equation by following ways: ✅

✿ Mass - mass analysis
✿ Mass - volume analysis
✿ Mole - mole analysis

Electric Charges and Fields

1. Electric Charge Charge is the property associated with matter due to which it produces and experiences electric and magnetic effect.

2. Conductors and Insulators Those substances which readily allow the passage of electricity through them are called conductors, e.g. metals, the earth and those substances which offer high resistance to the passage of electricity are called insulators, e.g. plastic rod and nylon.

3. Transference of electrons is the cause of frictional electricity.

4. Additivity of Charges- Charge are scalars and they add up like real numbers. It means if a system consists of n charges q1, q2, q3 , … ,qn, then total charge of the system will be q1 +q2 + … +qn.

5. Conservation of Charge The total charge of an isolated system is always conserved, i.e. initial and final charge of the system will be same.

6. Quantisation of Charge -Charge exists in discrete amount rather than continuous value and hence, quantised.

Mathematically, charge on an object, q=±ne
where, n is an integer and e is electronic charge. When any physical quantity exists in discrete packets rather than in continuous amount, the quantity is said to be quantised. Hence, charge is quantised.

7. Units of Charge

(i) SI unit coulomb (C)
(ii) CGS system

(a) electrostatic unit, esu of charge or stat-coulomb (stat-C)

(b) electromagnetic unit, emu of charge or ab-C (ab-coulomb)
1 ab-C = 10 C, 1 C = 3 x 109 stat-C
