Fixed joint is the one where there is no relative movement of the bones. The joint between the head and the upper jaw is an example of fixed joint.

(i) The stem carries water and minerals from the roots to·the different parts of the plant.
(ii) The stem provides support to the branches, leaves, flowers and fruits.

The two devices that are used to measure length are:
(i) Metre-scale (ii) Screw gauge.

Few animals have adaptations to live both in water as well as land. These are called amphibians, e.g. frog and toad.

The object which partially allows the light to pass through it is a translucent Object, e.g. wax paper.

No, the people of all ages and different professions require different types of nutrients according to their physical work.

Yes, sprouting of pulses can be done. In this form, pulses are highly nutritious.

Ingredients are the components needed to prepare a particular dish.

The presence of proteins in food items is tested by using following steps :
Step I: Take a small quantity of food item in a test-tube.
Step II: Add 10 drops of water into it and shake the test-tube
Step III: With the help of dropper, add two drops of copper sulphate solution.
Step IV: Add 10 drops of caustic soda solution to the test-tube and shake the test tube and leave it for a few minutes.
The appearance of violet colour indicates the presence of proteins in the food item.

(i) Prey: An animal hunted or caught for food.
(ii) Predator: An organism that lives by preying on other organisms is called a predator.
(iii) Acclimatization: It is the process in which an individual organism adjusts to a gradual change in its environment (such as a change in temperature, humidity, photoperiod, or pH) allowing it to maintain performance across a range of environmental conditions. Acclimation occurs in a short period of time (days to weeks), and within the organism's lifetime
(iv) Adaptation: In biology, an adaptation, also called an adaptive trait, is a trait with a current functional role in the life history of an organism that is maintained or developed by means of natural selection. Adaptation refers to both the current state of being adapted and to be in the dynamic evolutionary process that leads to the adaptation.
(v) Stimuli: An agent, action, or condition that elicits or accelerates a physiological or psychological activity response.

By following these simple steps, we can make hard gifting boxes or other articles from the recycled paper pulp:
Step I Create a stencil by unfolding a small, one piece cardboard box and trace it on a piece of cardboard that is the same size as your mold. Then, cut out that shape with scissors.
Step II Place the box stencil between your mold and deckle.
Step III Raise the mold, deckle and stencil to the surface in one continuous motion and then remove them from the pulp.
Step IV Remove the box from the stencil and let the paper dry.
Step V Assemble the box by folding and gluing or taping the edges. Decorate it as your need.

The family X is more environment friendly/conscious because they dispose off their kitchen waste and polythene bags separately.
Disposing them separately has an advantage as kitcher waste is biodegradable and can be converted into compost. Polythene bags on the contrary are non-biodegradable.

Yes, the shadow will be formed in all the cases but in all the cases, the darkness of the shadow will be different.
(i) Most of the light in case of transparent sheet will pass through the glass. So, the darkness of shadow will be very low.
(ii) Also most the light in case of muslin cloth will be reflected. So, the shadow will be darker than the transparent sheet.
(iii) While in case of plywood, all the light would be stopped completely by the plywood. So, the darkness strength will be highest in this case.

(a) The doctor has diagnosed the fracture by taking photographs of bones, i.e. X-ray images.
(b) X-rays show us the images and shapes of different bones in our body.
(c) Friendly behaviour, sense of responsibility and kind nature are the values shown by Rishi's friends.

Elastic tapes are stretchable due to which their length can be increased during the measurement if it is not handle with care. Therefore, the measurement done by elastic tapes may be greater than the actual length of the object. So, we can say that elastic tapes are not accurate to measure a length.

(a) In the given figure:
(i) Petiole (ii) Midrib (iii) Lamina (iv) Vein
(b) The leaf has reticulate venation, the veins in leaf occur in an irregular way forming a net-like structure.
(c) Grass leaves have parallel type of venation. The vein run parallel to each other on both sides of midrib.

(a) Carbohydrates are the compounds made up of carbon, hydrogen and oxygen. These are formed in plants during photosynthesis, e.g., glucose.
(b) Carbohydrates found in our food are in the form of starch and sugar.

Three types of plants are :
1.Herbs 2. Shrubs 3. 'frees

No, in my opinion, Paheli's action was not responsible.
If I would have been in her place, I would have used the paper for doing rough work or convert it into paper pulp to make a handicraft item.

We see the following movements in plants
(i) Opening and closing of flower.
(ii) Growth of stem and leaves.
(iii) Growth of stem and twigs towards light and roots towards soil and water.

The light from the torch C will not form a shadow on the screen because light travels in a straight path and will form the shadow on the same path from which it is coming.

The bodies of insects, crabs, spiders have  hard covering made up of chitin. These animals do not have endoskeleton.
Instead, this hard covering gives them a shape, so it is called exoskeleton. Scales of fishes and cockroaches, outer shells of snail and oyster are also examples of exoskeleton

Accurate scale r-eading begins from zero as shown below

But here the reading on scale begins with 3 cm
Thus, the error in the scale = 3 cm- 0 cm= 3 cm
Now, the other end on the scale reads = 33.1cm
Thus, the actual length of the needle = (Reading on the other end - Error reading of first end)
= 33.1 cm - 3 cm = 30.1 cm
