• It  cant be Angiosperm because it is reduced to few cells. 

• Where as Bryophytes & Pteridophytes female gametophyte is retained in megasporangia.

• Therefore, It is clear that Gymnosperms suits the above option.

• Ans  :   [C] - GYMNOSPERMS 

• Adipose tissue is another type of loose connective tissue and not dense.
• Bones have a hard and non-pliable ground substance.
• Blood is a fluid connective tissue because it contain the above liquid and few gases.
• Yes, most of the cartilages in vertebrate embryo are replaced by bone in adult.
• At the age of 25 cartilages are replaced by bones with the help of Ca+ .    
• In which, the growth is retared.
• Ans - [C] 

The correct answer is Most of the cartilages in a vertebrate embryo are replaced in adult by bones

• Cartilage is a specialized type of dense connective tissue designed to give support, bear weight and withstand tension, torsion, and bending.
• In the vertebrate embryo, the greater part of the skeleton consists of cartilage, which is gradually replaced by bone during development.
• Early in development, cartilage makes up most of the vertebrate skeleton. As an individual grows older, calcium deposits form around the skeleton, and bone eventually replaces most of the cartilage. This process is called ossification. Ossification begins in humans when the fetus is still in the womb and is not complete until early adulthood
• Hence Most of the cartilages in the vertebrate embryo are replaced in the adult by bones

• Gram +ve bacteria have well inner layered membrane (i.e plasma membrane & peptidoglycan),but no lipid layer outer membrane.
• Gram +ve cell have thick,homogeneous cell wall made up of murine & mucopeptide.
• And, even they a large amount of teichoic acid found in cell wall,and extend to peptidoglycan layer
• Therefore,the ans is [D] all the above are correct 

The cost-of-carry ensures that the futures price stay in tune with the spot price. Whenever the futures price deviates substantially from its fair value, arbitrage opportunities arise.

Say for instance, ABC Ltd. trades at Rs.1000. One-month ABC futures trade at Rs.1025 and seem overpriced. As an arbitrageur, you can make riskless profit by entering into the following set of transactions.

1. On day one, borrow funds, buy the security on the cash/spot market at 1000. 

2. Simultaneously, sell the futures on the security at 1025. 

3. Take delivery of the security purchased and hold the security for a month. 

4. On the futures expiration date, the spot and the futures price converge. Now unwind the position. 

5. Say the security closes at Rs.1015. Sell the security. 

6. Futures position expires with profit of Rs. 10. 

7. The result is a riskless profit of Rs.15 on the spot position and Rs.10 on the futures position. 

8. Return the borrowed funds.

Various products have been designed based on the indices such as the index derivatives, index funds2 and the exchange traded funds. We here restrict our discussion to only index derivatives. 

Index derivatives are derivative contracts which have the index as the underlying. The most popular index derivative contracts the world over are index futures and index options. NSE‘s market index, the Nifty 50 was scientifically designed to enable the launch of index-based products like index derivatives and index funds. Index derivatives offer ease of use for hedging any portfolio irrespective of its composition.

VAR is a single number, which encapsulates whole information about the risk in a portfolio. It measures potential loss from an unlikely adverse event in a normal market environment. 

The VAR margin will be charged on the net outstanding position (buy value-sell) of the respective clients on the respective securities across all open settlements. There would be no netting off of positions across different settlements. The net position at a client level for a member is arrived at and thereafter, it is grossed across all the clients including proprietary position to arrive at the gross open position.

Market Watch 

The Market Watch window is the third window from the top of the screen that is always visible to the user. The Market Watch is the focal area for users. The purpose of Market Watch is to setup and view trading details of securities that are of interest to users. For each security in the Market Watch, market information is dynamically updated. 

Following are the key features of Market Watch Screen:

For each security the following information is displayed:

(a) the corporate action indicator ―Ex/Cum‖ 

(b) the total buy order quantity available at best buy price 

(c) best buy price 

(d) best sell price 

(e) total sell order quantity available at best sell price 

(f) the last traded price 

(g) the last trade price change indicator and 

(i) the Percentage change from previous day‘s closing price‘

a. Unlisted corporate trading member: In case of an unlisted corporate trading member, there are three conditions under which the corporate trading member will be eligible to constitute dominant promoter group. These conditions are given below: If a person holds 51% of shares in the trading member corporate on his own or together with 

1) His relatives 

2) The support of strategic investors in such corporate trading member. 

b) Foreign entities : Foreign entities are allowed to take trading membership of the Exchange through their Indian subsidiary under the automatic approval route permitted by the government, subject to compliance with the following guidelines of the RBI in this regard.

c) first absorb then release

(i) The magnetic field lines produced is into the plane of the paper at R and out of it at S. 

(ii) Field at S > Field at P Magnetic field strength for a straight current carrying conductor is inversely proportional to the distance from the wire. 

(iii) The current will be going from top to bottom in the wire shown and the magnetic field lines are now in the clockwise direction on the plane which is perpendicular to the wire carrying current. 

(iv) Right hand thumb rule. The thumb is aligned to the direction of the current and the direction in which the fingers are wrapped around the wire will give the direction of the magnetic field.

The lamps are in parallel. 

Advantages: 

If one lamp is faulty, it will not affect the working of the other lamps. They will also be using the full potential of the battery as they are connected in parallel. 

The lamp with the highest power will glow the brightest. 

P=VI 

In this case, all the bulbs have the same voltage. But lamp C has the highest current. 

Hence, for Lamp C 

P=5 x 60 Watt = 300 W. (the maximum). 

The total current in the circuit = 3+4+5+3 A = 15A 

The Voltage = 60V 

V=IR and hence R =\(\frac{V}{I}\)

= \(\frac{60}{15}\) A = 4A

Refractive index = \(\frac{speed\,of\,light\,in\,vacuum}{speed\,of\,light\,in\,medium}\)

Since the refractive index of diamond is more, hence the speed of light is lesser in diamond. 

Let speed of light in water vev_w and in diamond bev_d. 

Refractive index of diamond w.r.t water is say n = \(\frac{speed\,of\,light\,in\,water}{speed\,of\,light\,in\,diamond}\)

\(n=\frac{V_w}{V_d}\)

Dividing both numerator and denominator by speed of light [c] we get 

n = (\(\frac{V_w}{c}\)) ÷ (\(\frac{V_d}{c}\)) = Inverse Ratio of refractive index of water and diamond. 

n=\(\frac{2.42}{1.33}\) = 1.82 (approx.)

Baking soda undergoes thermal decomposition to form Na₂CO₃, CO₂ and H₂O; CO₂ makes the cake fluffy & soft

(i) a) B 

b) C,A,D,B 

(ii) Due to moisture in the atmosphere it converted into Gypsum

(iii) Making toys/dolls or statues /fixing broken limbs/making decorative materials.

Correct option is (3) Slime mould, Protozoans, Dionflagellates, Diatoms, Euglenoids

Given: A = x, B = 3x, C = y

∴ Sum of △le = x + 3x + y

180 = 4x + y

⟹180−4x = y

Also,3y − 5x = 30^∘

Subtituting y value,  

∴ 3(180−4x)−5x = 30

∴ x = 30, by solving

∴ y = 180−4×30 = 60

∴ A = 30^∘; B = 90^∘; C = 60^∘

Correct option is (2) Silica particles

Abcdef are alphabets

no they are not

(b) Clostridium

(c) Idioblasts

(b) Prevost & Dumans

Answer : D. All

Option D is correct

Answer : C. Amino acid 

Explain : On average, postprandial blood glucose may rise to 120 to 140 mg/dl, but the body's feedback mechanism returns the glucose to normal within 2 hours. During starvation, the liver provides glucose to the body through gluconeogenesis: synthesizing glucose from lactate and amino acids
