In normal conditions, RBCs are Biconcave disc- like. Sickle cell anemia is a group of disorders which comes under the sickle cell disease. It is an autosomal recessive disease therefore it can be transmitted from parents of the offspring when both female and male individuals are carriers for the gene. The disease is controlled by a single pair of alleles, Hb^A and Hb^S. Thus, three genotypes are possible in this situation:
- Hb^A Hb^A (normal homozygous) - Hb^A Hb^S (normal carrier) - Hb^A Hb^S Hb^S (diseased, die before attaining maturity)
Heterozygous (Hb^A Hb^S) individuals appear unaffected but they are carriers of the disease as there is a 50% probability of transmission of the mutant gene to the progeny, thus exhibiting sickle cell trait.
The disease or defect is caused by a mutation (transversion) of the gene controlling the β-chain of hemoglobin. It replaces glutamic acid (Glu) present at the 6^th position of the β-chain by amino acid Valine (Val) . The mutant hemoglobin molecules undergo polymerization under low oxygen tension causing the change in the shape of RBCs from biconcave to elongated sickle- like (curve) structure.

Biodiversity mainly depends on upon the climatic and geographical conditions available in a particular region. The Western Ghat runs along the western edge of peninsular India. It supports a diverse range of flora and fauna. There are over 6000 vascular plants belonging to over 2500 genera in this hotspot, of which over 3000 are endemic. It is a rich source of spices such as black pepper and cardamom. The highest concentration of species in the Western Ghats is believed to be the Agasthyamalai Hills in the extreme south. The region also harbors over 450 bird species, about 140 mammalian species, 260 reptiles, and 175 amphibians. Over 60% of the reptiles and amphibians are completely endemic to the hotspot. 

Methanal ( HCHO ) can be converted into propan-1-ol ( CHCHCHOH ) by following step of reactions -

(i). React methanal ( HCHO ) with ethyl magnesium bromide ( CHCHMgBr ) , CHCHCHOMgBr is formed .

(ii). React CHCHCHOMgBr with water ( HO ) , propan-1-ol  ( CHCHCHOH ) is formed .

• Methanal is also known as formaldehyde .
• Propan-1-ol is a colorless liquid . It's molar mass is 60.09 g / mol .

The constitution is a fundamental law of a country that reflects the fundamental principles on which the government of the country is based. In this article, learn some of the interesting features of the Indian Constitution.

• The bulkiest constitution of the world: The Indian constitution is one of the bulkiest constitutions of the world, comprising of 395 articles, 22 parts, and 12 schedules. So far the constitution underwent 100 amendments (28 May, 2015).
• Rigidity and flexibility: The Indian constitution is a combination of rigidity and flexibility, which means some parts of it can be amended by the Parliament by a simple majority, whereas some parts require a two-third majority as well as not less than one-half of the state legislatures.

1) Federalism

This refers to the existence of more than one level of government in the country. In India, we have governments at the state level, at the centre and Panchayati Raj at the village level. The Constitution contains lists that detail the issues that each tier of government can make laws on. In addition, the Constitution also specifies where each tier of government can get the money from, for the work that it does. All persons in India are governed by laws and policies made by each of these levels of government.

2) Parliamentary Form of Government

The people of India have a direct role in electing their representatives. Also, every citizen of the country, irrespective of his/her social background, can contest in elections.

3) Separation of Powers

There are 3 organs of government:

1. The legislature: refers to elected representatives by the people.
2. The executive: is a smaller group of people who are responsible for implementing laws and running the government.
3. The judiciary: refers to the system of courts in India.

Each organ mentioned above acts as a check on the other organs of government. This ensures the balance of power between all three.

The media and entertainment industry consists of film, print, radio, and television. These segments include movies, TV shows, radio shows, news, music, newspapers, magazines, and books. These types of advertisements are: Print Advertising: Newspaper, magazines, & brochure advertisements, etc. Broadcast Advertising: Television and radio advertisements. Outdoor Advertising: Hoardings, banners, flags, wraps, etc. Digital Advertising: Advertisements displayed over the internet and digital devices.

Current assets =4,10,000 
Current assets after payment of 50,000 : 4,10,000 - 30,000(Cash Given) =  Rs3,80,000 . 
As current ratio 2.4 and current assets are Rs 3,80,000
Current Ratio = Current Assets/Current liabilities
Therefore, Current liabilities =3,80,000/2.4 = 158333
Working capital = current assets - current liabilities = 3,80,000 - 1,58,333 =      Rs 221667
