Given,

Average of seven consecutive numbers = 33

Let the seven consecutive numbers be

Sum of the seven numbers

= 7x

As we know,

Average

⇒ x = 33

So, largest number  = x + 3
= 33 + 3
= 36
∴ The largest number in the consecutive series is 36.

In 200 mixture, milk  = liter

Water in the mixture=200-160 = 40 liter

Let the quantity of mixture is taken out = 5x

Then,  

480 - 12x = 350 - 7x 

5x = 130

x = 26 

Quantity of mixture taken out = 130 liter

So, there is a total of 6 squares in the figure.

The logic followed here is as follows:

7 - 3 = 4th day will be Saturday - 3 = Wednesday

Anil ranks 7th from the top.

Rohit is 3 ranks behind Anil, which means Rohit's rank is 10th (7 + 3) from the top.

Rohit is 7 ranks ahead of Sumit, which means Sumit's rank is 17th (10 + 7) from the top.

Vijay is 32 ranks behind Sumit, which means Vijay's rank is 49th (17 + 32) from the top.

Vijay's rank is 49th from the top and 4th from the bottom, which means the total number of students = 49 + 4 -1 = 52.

Given:

Students from the physics department from college A = 50
Students from the math department from college A  = 65
Students from chemistry department from college C = 70
Students from the math department from college C = 85
Total number of students from physics and math department from college A  = (50 + 65) = 115
Total number of students from chemistry and math department from college C = (70 + 85) = 155
Now, the ratio between them  = 115 : 155
= 23 : 31
∴ The ratio between them is 23 : 31.

Given:

Number of students from chemistry department from college B = 95

Number of students from chemistry department from college C = 70

Number of students from physics department from college A = 50

Number of students from physics department from college D = 60
Total students from chemistry department from both college B and college C
Total students from the physics department from both colleges A and college D
So, the difference between the students from two departments
∴ The difference between the total number of students from the chemistry department from college B and college C and the total number of students from the physics department from college A and college D is 55.

Given:
The number of coins tossed is 5 coins.

Formula used:

The number of ways for obtaining three heads from five trials
Total number of outcomes from the trial of five coins  = 2⁵ = 32
The required probability = 10/32 = 5/16

∴ The probability of exactly 3 heads is 5/16.

Given:
Cost = Rs. 3200
Down payment = Rs. 1000
Installments = Rs. 1200 each
Calculation:
Let the rate percent be R % per annum,
Total payment due to installment = 2400 + 1000
= 3400
Interest amount = 3400 − 3200 = 200
So, Principal for the 1 st month = Rs. (3200 − 1000)
= 2200
So, Simple interest for 1 st month 
Now, Principal for the 2nd month = Rs. (2200 − 1200)
= Rs. 1000
So, Simple interest for 2 nd month 
So, According to the question,

In water-logged soil, plants do not grow properly because the soil is physiologically dry.

Physiologically dry soil means that water is present in the soil but is not available to the plants either because of high salt concentration, or lack of water in liquid form or poor aeration. These conditions respectively occur in saline marshes, cold deserts and waterlogged soil.

Salamander is included in the ammonotelic animals.

An ammonotelic organism excretes nitrogenous waste as soluble ammonia.

Most of the aquatic animals including protozoan, crustaceans, Platyhelminthes, cnidarian, poriferans, echinoderms, fishes, larva/tadpoles of amphibians are ammonotelic.

A niche is a place. But in ecological terms, it means the manner in which an organism responds to its environment. It includes the way in which an organism survives, the manner in which it can t feeds itself, obtains shelter and it's overall behavior. For example, a rabbit alters soil fertility by digging burrows, adding feces to it and it is eaten away by beetles, dogs, cats, etc. It is a herbivorous animal as it lives in grasslands and feeds on grasslands. 

A young infant may be feeding entirely on mother's milk which is white in colour but the stools which the infant passes out is quite yellowish. The yellow colour of stool is due to bile pigments passed through bile juice.

The yellow colour of the stools is due to the presence of bile pigments. Bile pigments are the excretory products. Bile is a bitter-tasting greenish-yellow alkaline fluid produced by the liver and stored in the gall bladder and secreted into the duodenum. It assists the digestion and absorption of fats by the action of bile salts, which chemically reduce fatty substances and decrease the surface tension of fat droplets so that they are broken down and emulsified.

Mutation in single nucleotide base of a DNA segment is called as a point mutation. It occurs by substitution or frameshift mutation. Exchange of one nitrogenous base for another base is called as substitution; option C is correct. The transition is the substitution of one type of base by other of its own type (purine –purine and pyrimidine –pyrimidine). Substitution of purine base for a pyrimidine base or substitution of pyrimidine base for a purine base is called as transversion. The gene mutations that alter the base sequence of the whole genetic frame from the point of the mutation are called frame shift mutations. Here, the reading frame of the base sequence is shifted forward (due to insertion of one or more nucleotide base) or in the backward direction (due to deletion of one or more nucleotide base); options A and B are correct. Duplication is the presence of extrachromosomal segment which is attached to the normal homologous chromosome causing duplication of a set of genes in the same chromosome; thus it is not a point mutation. 

Pseudostratified epithelium makes up the Lining of the trachea.

Pseudostratified epithelium is a single cell layer specially the goblet cells. The Goblet cells are one to produce moisty fluid called mucus that attracts germs entering into the organ and thus purifies the tract. Also, it has ciliary muscles that perform a lashing movement making passage of air even easier through the Trachea. Since it is concerned with providing protection to the organ.

DNA polymerase can polymerize nucleotides only in direction on strand because it adds them at the end. Since, the two strands of DNA run in antiparallel directions, the two templates provide different ends for replication. Replication over the two templates thus proceeds in opposite directions. One strand with polarity forms its complementary strands continuously because end of the latter is open for elongation. It is called leading strand. Replication is discontinuous on the other template with polarity because only a short segment of DNA strand can be built in direction due to exposure of a small stretch of template at one time. Short segments of replicated DNA are called Okazaki fragments.
