An entrepreneur is a person who undertakes a venture with some profit potential and involving a considerable amount of risk and therefore, entrepreneurship is the venture undertaken by the entrepreneur. The most obvious example of entrepreneurship is the starting of a new business.

Characteristics of Entrepreneurship

While there can be as many characteristics of entrepreneurship as there are people in this world with opinions, there are some characteristics that are considered indispensable or necessary in an entrepreneur. These are listed here as follows.

Ability to take Risks

This is the first and foremost trait of entrepreneurship. Starting any business involves a considerable amount of risk of failure. Therefore, the courage and capacity to take the said risk are essential for an entrepreneur.

Innovation

In a world, where almost everything has been done, innovation is a priceless gift to have. Innovation basically means generating a new idea with which you can start a business and achieve a substantial amount of profits. Innovation can be in the form of a product, i.e., launching a product that no one is selling in the market. It can also be in the form of process, i.e., doing the same work in a more efficient and economical way.

Mitochondria are virtually the only colored parts of the cell.

If it were not for the melanin in our skin, the myoglobin in our muscles, and the hemoglobin in our blood, we would be the color of mitochondria--that is, a brownish red.

Optimism is a determination to overcome difficulties. It raises one’s spirits and helps one overcome stress and difficulty with ease. The story displays courage and optimism shown by everyone at the time of a difficult situation. Survival happens only because of the optimistic struggle that the family carries on with the inclination to look at the bright side in the situation.
The level of perseverance in the author rises when Jonathan says, “We’re not afraid of dying if we can all be together. Besides, the caricatures of him and Mary, drawn by Sue, helps his determination and optimism to grow many folds. The positive outlook of the children infuses positivity in the narrator. He rigorously calculates their position and finally asks Larry to steer a course of 185 degrees. Though he lost all hopes by then, he does not show it and optimistically told Larry that they would spot the island by about 5 p.m. Fortunately, their struggle and optimism pays off and they manage to find Ile Amsterdam by the evening.

The formula of urea is NH2CONH2
Molar mass = 60.01 g/mol
Atomic mass of N = 14 and 
Number of atoms = 2
That means, 14 {tex}\times{/tex} 2= 28g/mol of urea
MW urea = 60.1
%N = 100% x 28.0 g N / 60.1 g urea = 46.66 %N
Or 
%N= 28/60{tex}\times{/tex}100= 46.66 % N

The chemical formula and molar mass of calcium chloride are respectively CaCl2 and 111 g respectively. Thus, there are 6.022{tex}\times{/tex}1023 formula units in 111g of CaCl2. So,
number of formula units of CaCl2 in 111 g of CaCl2 = 6.022 {tex}\times{/tex}1023
number of formula units of CaCl2 in 1g of CaCl2 = {tex}\frac{(6.022\times1023)}{111}{/tex}

number of formula units in 222g of CaCl2 ={tex}\frac{(6.022\times1023\times222)}{111}{/tex} 
= 12.044 {tex}\times{/tex} 1023
Now, each formula unit of CaCl2 contains one Ca2+ ion and two Cl- ions. Therefore
number of Ca2+ ions in one unit of CaCl2 = 1
number of Ca2+ ions in 12.044 {tex}\times{/tex} 1023 units of CaCl2 = 1 {tex}\times{/tex} 12.044 {tex}\times{/tex} 1022 = 1.2044 {tex}\times{/tex} 1024
Similarly
number of Cl- ions in one unit of CaCl2 = 2
number of Cl- ions in 12.044 {tex}\times{/tex} 1023 units of CaCl2 = 2 {tex}\times{/tex} 12.044 {tex}\times{/tex} 1023
= 2.4088 {tex}\times{/tex} 1024
Hence, there are 1.2044 {tex}\times{/tex} 1024 Ca2+ ions and 2.4088 {tex}\times{/tex} 1024 Cl- ions in 222 g of CaCl2.

A balanced diet refers to balance of food groups or protein fat and carbohydrate, fluid, and calories. In order to maintain optimal health and weight, an overall balanced diet is key. A balanced diet consists of whole grains, fruits, vegetables, dairy, lean proteins, and healthy fats.

The force applied in that direction and directly proportional to the mass and acceleration.

Poster:

Essentially, a very brief communication with a compelling visual and a powerful message, a poster is always prepared with a particular target audience in mind. It very clearly mentions the theme or the topic, the schedule of an event and the respective occasion. It can be of the following types :-

• An appeal for awareness or support, help or action, a warning or a caution.
• In the form of an invitation like posters for carnivals, fests, concerts, exhibitions, etc.
• Workshops, seminars.

Format can be:

ISSUING AUTHORITY- By whom or by which organisation the poster is being published.

TAGLINE OF THE EVENT- it has to be in accordance with the question. A catchy tagline for the occasion. It should be clearly visible. Thus, it can be bold, underlined or in capitals.

TITLE OF THE EVENT- it should be short and as per the question.

SPECIAL ATTRACTIONS- This is optional. For example:- Guest speaker, etc.

ILLUSTRATION- It involves pictorial representation. For eg., a drop of blood for a blood donation camp.

DATE, TIME AND VENUE- It is very important to mention date, time and venue of the event. It  is a point you cannot risk forgetting.

CONTACT INFORMATION- In case of any queries, the targeted audience should have someone to contact to.

OTHER RELEVANT INFORMATION- If there is any other information mentioned in the question and is supposed to be there in the poster, it is important you mention it.

The main difference between freshwater and marine life is the habitat they come from in the wild. Freshwater fish live in streams, rivers and lakes that have salinity of less than 0.05 percent. Depending on the species, fish can survive in temperatures ranging from 5 and 24 degrees Celsius. They can adapt to a change in habitat, like the rise and fall in water levels, temperature and oxygenation levels. Marine life refers to fish living in oceans and seas. These are also known as saltwater fish because they can only stay alive in waters with high salinity levels. A marine animal's habitats include coral reef and seagrass bed.

The endocrine system is composed of several endocrine glands. A ductless gland is called endocrine gland. Endocrine gland secretes its product directly into the bloodstream. Hormones are produced in the endocrine glands.
