It consist of Ovaries,oviduct,fallopian tubes,uterus,******.
1)Ovaries:They are oval shaped organ, inside abdominal cavity.There are 2 ovaries, makes egg or ova and *** hormones, composed of thousand of follicles.At puberty these follicles mature to form ripe egg.
2)Oviducts:Above the ovaries,not connected directly to ovaries but have funnel shaped opening which almost cover ovaries.
The egg released by an ovary goes into oviduct through funnel shaped opening.Fertilisation take place in oviduct.
3)Uterus:The two oviducts connect to a bag like organ called uterus.the growth and development of fertilised egg take place in uterus.
4)Cervix:Uterus is connected through a narrow opening called cervix to another tube called ******.

A stakeholder is a person with an interest in a particular business. Everyone uses forest resources in one form or the other. The stakeholders of forest resources include:
- People who live around the forest areas and depend upon the forest resources for sustenance.
- The Government Forest Department, which owns the forest land
- The industrialists who use forest products for various industrial purposes.
- The enthusiasts for the conservation of wildlife and nature.
The people staying in nearby areas use firewood, thatch, and small timber from the forests. Bamboo is used in making huts, and baskets for collecting fruits and food materials. Forests are also the sites for hunting and fishing. The industries consider the forest as a source of raw materials for the factories. The industrialists are not concerned about sustainability.
Before independence, the stakeholders were free to use forest resources. But after the British took over, the access of forest resources was restricted to the forest dwellers. After independence, the government overtook forest departments, but the interest of the people staying in forests was still ignored. A few cultivation practices disturbed the whole biodiversity of the area.

- Hydrochloric acid is an essential acid in the stomach.
- It helps destroy bacteria, as well as other harmful species.
- It also works as a preservative of food.
- HCl converts pepsinogen which is not active into pepsin to metabolize proteins in our stomach.

The tiny projections on the inner surface of the small intestine which help in absorbing the digested food are called villi. These helps to increase the surface area of intestinal walls.
Location
These are located in the inner walls of the small intestine.
Functions
- Their function is to increase the surface area of the small intestinal wall for absorption of the digested food.
- These projections absorb the protein molecules and help in the transfer of the proteins to all cells and tissues.
- Many blood vessels are present within these villi, that help in the absorption of digested food and carry it to the bloodstream. Later, from the bloodstream, the absorbed food is delivered to each and every cell of the body.

An amylase or ptyalin
An amylase or ptyalin present in saliva, that catalyzes the hydrolysis of starch into maltose and dextrin. An enzyme found in the saliva of humans and herbivorous animals that helps in the pre digestion of starches. Ptyalin is a type of amylase. Pepsin, rennin and lipase are absent in saliva.

b.
Carbon forms a large number of compounds because of the following reasons:
(a) Tetravalency: Carbon atoms readily form covalent bonds with the other atoms.
(b) Catenation: Two carbon atoms readily form covalent bonds and this bond is more stable than the bonds formed by the other elements.
(c) Carbon atoms have varying bond order and hybridisation that is it can form double or triple bonds.
(d) The electronegativity of the carbon atom is average.

a. Saturated hydrocarbons produce clean flame while unsaturated carbon compounds produce yellow flame with black smoke. The burning of carbon compounds results in a sooty deposit on the surface or a sooty flame if there is an incomplete combustion of saturated hydrocarbons due to limited supply of air.

Chloroplasts are found in all green plants and algae. They are the food producers of plants. These are found in the guard cells located in the leaves of the plants. They contain a high concentration of chlorophyll that traps sunlight. This cell organelle is not present in animal cells.
Chloroplast has its own DNA and can reproduce independently, from the rest of the cell. They also produce amino acids and lipids required for the production of chloroplast membrane.
Structure of Chloroplast
Chloroplasts are found in all higher plants. It is oval or biconvex, found within the mesophyll of the plant cell. The size of the chloroplast usually varies between 4-6 µm in diameter and 1-3 µm in thickness. They are double-membrane organelle with the presence of outer, inner and intermembrane space. There are two distinct regions present inside a chloroplast known as the grana and stroma.
- Grana are made up of stacks of disc-shaped structures known as thylakoids. The grana of the chloroplast consists of chlorophyll pigments and are the functional units of chloroplasts.
- Stroma is the homogenous matrix which contains grana and is similar to the cytoplasm in cells in which all the organelles are embedded. Stroma also contains various enzymes, DNA, ribosomes, and other substances. Stroma lamellae function by connecting the stacks of thylakoid sacs.

The sunlight that reaches the earth’s atmosphere is scattered in all directions by the gases and dust particles present in the atmosphere. The blue colour is scattered more and hence the sky appears blue. The reason for more scattering of blue colour is that the wavelength of the blue light is shorter than the other light. So blue light is scattered in all directions by the tiny molecules of air in Earth’s atmosphere. This the reason for the blue appearance of the sky.

c) A is true, but R is false.
A solution of slaked lime (Ca(OH)2) is used to white wash the walls. Calcium hydroxide reacts with the carbon dioxide in air to form thin layer of calcium carbonate on the walls. It gives a shiny finish to the walls.

The potential difference (voltage) across an ideal conductor is proportional to the current through it. The constant of proportionality is called the "resistance", R. 2. Material that obeys Ohm's Law is called "ohmic" or "linear" because the potential difference across it varies linearly with the current. In a series circuit, the current is the same at each resistor. ... The voltage drop (I•R) will be the same for each resistor since the current at and the resistance of each resistor is the same. Thus the electric potential difference across any one of the bulbs will be the same as that across any one of the other bulbs.

At noon we know that the sun is overhead and when the sun is overhead , it has less air to travel through. We also know that scattering occurs due to dust and other suspended particles in air . So, scattering is reduced if the distance to be travelled in air is reduced.

The appendix or vermiform appendix is a muscular structure attached to the large intestine in the human body. It is a narrow tube resembling a worm and is named after the Latin word "vermiform" which means ‘worm-shaped’. The appendix extends from the lower end of the cecum, a pouch-like structure in the large intestine.

| Acid radicals |
| Negatively charged radicals are called acidic radicals. |
| Acid radicals are formed by removal of hydrogen ion (H+). |
| Example: H2S04 loses one H+ ion to form HSO4– ion. |
| Basic radicals |
| Positively charged radicals are called a basic radical. |
| Basic radicals are formed by the removal of hydroxide ion (OH–). |
| Example: KOH loses OH– ion and becomes K+ ion. |

The electrical resistance of a wire would be expected to be greater for a longer wire, less for a wire of larger cross sectional area, and would be expected to depend upon the material out of which the wire is made.The resistance of a wire can be expressed as R=ρ L/A,
where,
ρ - Resistivity - the factor in the resistance which takes into account the nature of the material is the resistivity
L - Length of the conductor
A - Area of cross section of the conductor.
From this relation, we observe that the length is directly proportional to the resistance and the area of cross section is inversely proportional to the resistance.
That is, if L becomes 2 L, R becomes 2 R. R′=ρ 2L/A. So, R = 2R'.
Hence, If the length of a wire is doubled, then its resistance becomes 2 times.
