tory centres around relationship of a young widow and her handicapped child. Anne wanted a different kind of child. Mothers should never insist on the inadequacy of a child - such children in particular need the support of unreserved love. - handicap should not be treated as a deterrent - not encourage "foolish longings", no impositions Examples from the text - Anne not willing to allow Freda to play with Marian. 

Employees were kind and helpful.

To serve her parents in old age and to teach the students in the same school where she had learnt too much. 

The four most important factors that influence crop yield are soil fertility, availability of water, climate, and diseases or pests. These factors can pose a significant risk to farms when they are not monitored and managed correctly.

Deforestation is the removal of a forest or stand of trees where the land is thereafter converted to a non-forest use.

Significance of Respiration are : 

(a) Respiration provides energy for the biosynthesis of cellular materials such as carbohydrates, proteins, fats, lipids, vitamins, pigments, etc.

(b) It is also a source of energy for cell division, growth, repairs and replacement of worn out parts, movements, locomotion, etc.  

(c) Various intermediates of Krebs cycle are used as building blocks for synthesis of other complex compounds. 

(d) Coupled with photosynthesis, it helps to maintain the balance between CO₂ and O₂ in the atmosphere.

(e) Anaerobic respiration is used in the various industries such as dairies, bakeries, distilleries, leather industries, paper industries etc. It is used in the commercial production of alcohol, organic acids, vitamins, antibiotics.

(f) Energy of respiration is also used to convert insoluble substances into soluble form.

The particulate pollutants and gaseous pollutants of the exhaust will get into atmosphere as otherwise 99% of the particulate matter is absorbed by Electrostatic precipitator. These pollutants cause respiratory disorders.

Process involved in removal of nitrogenous / harmful metabolic waste from the body.

(i) (a) Ovary : (i) Production of female hormone
(ii) Production of female gamete 
(b) Oviduct : (i) Transfer of female gamete from the ovary
(ii) Site of fertilization 
(c) Uterus : (i) Implantation of the zygote
(ii) Nourishment of the developing embryo 
(ii) Structure of Placenta : It is a disc like structure embedded in the uterine wall connected to the embryo. It has villi on the embryo's side of the tissue and on the mother side, it has blood spaces, which surrounds the villi.

Function of Placenta : It provides a large surface area for nutrients/glucose and oxygen to pass from the mother's side to the embryo and waste substances from the embryo's side to mother's blood.

The biological process which involves the removal of harmful metabolic wastes from the body of an organism is called excretion.

Laws of Refraction

(i) The incident ray, the refracted ray and the normal to the transparent surface at the point of incidence all lie in the same plane.

(ii) The ratio of the sine of the angle of incidence in the first medium to the sine of the angle of refraction in the second medium is a constant for a given pair of medium and for a given wavelength of light.

n=sin i / sin r

Absolute refractive index of a medium is defined as the ratio of the speed of light in vacuum or air to the speed of light in the medium. It is denoted by n.

n=speed of light in air (c) / speed of light in medium (v)

Basic filtration unit present in the kidney is Nephron.

The reciprocal of the focal length of a lens is termed as power of a lens.

Power= 1/ Focal length

SI unit of power is Dioptre.

Focal length +40 cm of a lens tells that it is convex lens as its focal length is in positive =p=1/f=100/40=+2.5D

Focal length - 20 cm tells that it is concave lens=p=1/f= 100/-20=5D.

Management of forest and wildlife resources are considered as a challenging task because : 

(i) There are many stakeholders of forest. Management of forest and wildlife has to take into account the interests of all these stakeholders which become a challenging task. 

(ii) Industries would consider the forest as merely a source of raw material for its factories and huge interest groups lobby the government for access to these ran' materials at artificially low rates which further pose a challenge to manage the forest and wildlife resources.

Electric circuit : The closed path along which an electric current flows is called an ‘electric circuit’. The device that helps to maintain a potential difference across a conductor in a circuit are : electric cell, electric battery, electric generator.
1 Volt : The potential difference between two points in an electric field is said to one volt if one joule of work has to be done in bringing a positive charge of one coulomb from one point to another.
1 Volt =1Joule/1Coulomb  or 1 V =1J/1C
Work done = V (Potential difference) × Q (Coulombs)
W = V × Q= 85 × 2 = 170 Joule

• The ScrumMaster is the servant leader to the Product Owner, Development Team and Organization with no hierarchical authority over the team but rather more of a facilitator, the ScrumMaster ensures that the team adheres to Scrum theory, practices, and rules.
• The ScrumMaster protects the team by doing anything possible to help the team perform at the highest level.

e-Publishing is also referred as electronic publishing or digital publishing or online publishing. It includes the digital publication of ebooks, digital magazines, and the development of digital libraries and catalogues.

It differs from traditional publishing in two ways:

(i) It does not include using an offset printing press to print the final product.

(ii) It avoids the distribution of a physical product (e.g., paper books, paper magazines, or paper newspapers).

Main advantages of e-Publishing are as follows:

• Digital publication products are easy to produce and edit.
• Digital publication products can be made available immediately on the Internet.

F11 key is used to insert/create chart for the selected cell in MS-excel.

Static Content 

The content of a website that remains the same across pages is referred to as static content. This could be served from a database as well, but it would be the same across all pages. For instance, the navigation menu, logo of the website, or any other information on the header or footer would not depend on inputs from the visitor.  In the following screenshot, the static content is highlighted in yellow and dynamic content is highlighted in red for easy reference.

Dynamic Content 

The content of a website that does not remain constant and changes according to user input(s) is referred to as dynamic content. For instance, in case of a product page, all product details such as Product Name, Price, Quantity, and Description are stored in a database and are fetched when a user is viewing a the webpage of a particular product. Therefore, this content is dynamically generated by the CMS and it changes across products.

Idempotent Law – An input that is AND´ed or OR´ed with itself is equal to that input   

A + A = A    A variable OR’ed with itself is always equal to the variable 

A . A = A    A variable AND’ed with itself is always equal to the variable

Proof: 

x + x = (x + x) • 1  (1 is the identity for AND)

= (x + x) • (x + x')   (Complement, x + x' = 1) 

= x + (x • x')    (OR distributes over AND) 

= x + 0    (Complement, x • x' = 0)

= x        (0 is the identity for OR)

(a) p₁: stable equilibrium

p₂: unstable equilibrium

The electric field, on either side, is directed towards the negatively charged sheet and its magnitude is independent of the distance of the field point from the sheet. For position p₁, dipole moment and electric field are parallel. For position p₂, they are antiparallel.

(b) The dipole will not be in equilibrium in any of the two positions.

The electric field due to an infinite straight charged wire is non- uniform (E α 1/r).

Hence there will be a net non-zero force on the dipole in each case.

From energy conservation, U_i + K_i = U_f + K_f
