Explanation

Passive immunity is provided to the fetus when maternal antibodies (especially IgG) cross the placenta.

This protection is temporary.

It helps the baby fight infections until its own immune system develops.

Explanation

Given:

g : h = 8 : 9

h : i = 9 : 12

To find the combined ratio g : h : i, we need to make the ratio of h the same in both.

g : h = 8 : 9

h : i = 9 : 12

Since h has the same ratio in both (9), we can directly combine:

g : h : i = 8 : 9 : 12

Explanation

Mir Qasim was the Nawab of Bengal before the Battle of Buxar in 1764.

He had replaced Mir Jafar with British support but later clashed with them.

He allied with Shuja-ud-Daula (Oudh) and Shah Alam II (Mughal Emperor) against the British East India Company.

The English Army in the Battle of Buxar was led by Hector Munro.

Explanation

Gestalt psychology emphasizes that the whole is greater than the sum of its parts, especially in perception and learning.

It argues that studying parts in isolation misses how the mind organizes information into unified wholes.

Explanation

The sequence of plants planted each year is an arithmetic sequence with:

First term (a) = 6000

Common difference (d) = 2200

To find the number of plants in the 7th year, we need to find the 7th term:

a₇ = a + (n - 1)d

= 6000 + (7 - 1) × 2200

= 6000 + 6 × 2200

= 6000 + 13200

= 19200

Explanation

Explanation

The sentence is a second conditional (imaginary/unreal situation in the present), using "if + past tense" and "would + base verb".

Since it says "if the weather were good", the correct structure is: "We would play football."

Explanation

Given:

log₈₁ 9 = x

We can rewrite this in exponential form:

81^x = 9

Since 81 = 9², we can rewrite:

(9²)^x = 9

9^(2x) = 9¹

Equating the exponents:

2x = 1

x = 1/2

x = 0.5

Explanation

The Law of Exercise, proposed by Edward Thorndike, includes two sub-laws: Law of Use (practice strengthens learning) and Law of Disuse (lack of use weakens learning).

It emphasizes that repetition strengthens associations, while neglect causes them to fade.

Explanation

Connective tissues include bone, blood, cartilage, and adipose (fat) — all of which support, bind, or transport substances in the body.

These tissues form the structural framework.

It play roles in protection, storage, and transportation of nutrients and oxygen.
