1) SALIVARY AMYLASE = mixes in the mouth, 30% starch present in the food broken down into maltose. 2) PEPSIN = mixes in the stomach, proteins broken down into peptones. 3) TRYPSIN = mixes in the duodenum, peptones broken down into peptides. 4) PANCREATIC AMYLASE = mixes in the duodenum, remaining 70% starch broken down into maltose. 5) PANCREATIC LIPASE = mixes in the duodenum, breaks down emulsified fats partially into fatty acids and glycerol. 6) PEPTIDASE = mixes in the small intestine, peptides broken down into amino acids. 7) INTESTINAL LIPASE = mixes in the small intestine, remaining emulsified fats broken down into fatty acids and glycerol. 8) MALTASE = mixes in the small intestine, maltose broken down into glucose.

It maintains the pH of our mouth and controls the production of acids. When the pH of our mouth goes below 5.5, the bacteria in the mouth gets activated and acids are produced. These acids neutralise calcium phosphate (more accurately, calcium hydroxyapetite), a basic salt which makes up our enamel. This leads to tooth decay. Therefore, to prevent this situation, Brushing twice in a day is advised.

Adithya Dev A 4 years, 7 months ago

Iron is more reactive than copper. Therefore, when an iron nail is dipped in a copper sulphate solution, the iron displaces copper from its copper sulphate solution. This leads to formation of iron (I) sulphate which causes the colour of the solution to change from blue to green.

How is food transport in plant ?

Posted by Damini Dugga 4 years, 7 months ago

CBSE > Class 10 > Science

3 answers

Pankaj Kumar Patel 4 years, 7 months ago

Food is transport in plant through the process of translocation. The two sources of transferring food in plants are phloem and xylem .phloem transport food product which make plants itself in every part of the plants and xylem transports water and mineral to the every part of the plants.

Ananya Jaiswal 4 years, 7 months ago

Food transport is through the process of translocation Phelom carries food from leaves to other part of the plant.

Adithya Dev A 4 years, 7 months ago

Through an active process known as translocation. TRANSLOCATION is the process by which the soluble products of photosynthesis are bidirectionally transported to all parts of the plant. It requires energy. When energy is supplied to the phloem tissue, it becomes an area of higher concentration. This ensures that the soluble food reach areas of low concentration (where there is acute need for food) through simple diffusion from phloem tissue.

Why respiration considered an exothermic reaction

Posted by Pratik Kumar 4 years, 7 months ago

Sanskar Shukla 4 years, 7 months ago

During respiration our body's glucose gets react to oxygen to form CO2 ans h2o with heat energy as in photosynthesis co2 ,h20 and heat reacts to form c6h12o6 and co2 that's why respiration is known as exothermic reaction as well as the opposite of photosynthesis

Jasleen Gill 4 years, 7 months ago

Respiration is considered as an exothermic reaction because energy is released in this process. Glucose combines with oxygen present in our cells to form CO2 and H2O along with energy.

Rajiv Maan 4 years, 7 months ago

Carbohydrates present in food are broken down to form glucose. This glucose combine with oxygen in the cells of our body and provides energy. This reaction is known as respiration, hence, it is considered as an exothermic reaction.

Why does the sun appear white at noon , why not any other instance

Posted by Navya Sravani 4 years, 7 months ago

CBSE > Class 10 > Science

2 answers

Navya Sravani 4 years, 7 months ago

Thanks

Adithya Dev A 4 years, 7 months ago

At noon, the rays of sunlight have to travel comparitively lesser distance while passing through the earth's atmosphere and fall normal to the earth's surface. This causes the blue and violet lights to get scattered in a less intense manner along with the red lights. Thus, sun appears white at noon. But, at other instances, the distance increases increasing amount of scattering of blue and violet lights causing lights of longer wavelengths to reach our eyes. So, sun appears white ONLY at noon.

ANSWER

An object 5 cm in length is held 25 cm away from a converging lens of focal length is 10 cm . draw the ray diagram and find the position ,size and nature of the image formed

Posted by Sheena Garg 4 years, 5 months ago

CBSE > Class 10 > Science

1 answers

Preeti Dabral 4 years, 5 months ago

Given, height of object = 5cm

Position of object, u = - 25cm

Focal length of the lens, f = 10 cm

Hence, position of image, v =?

We know that,

1/v - 1/u = 1/f

1/v + 1/25 = 1/10

So, 1/v = 1/10 - 1/25

S0, 1/v = (5 - 2)/50

That is, 1/v = 3/50

So, v= 50/3 = 16.66 cm

Thus, distance of image is 16.66 cm on the opposite side of lens.

Now, magnification = v/u

That is, m = 16.66/-25 = -0.66

Also, m= height of image/height of object

Or, -0.66 = height of image / 5 cm

Therefore, height of image = -3.3 cm

The negative sign of height of image shows that an inverted image is formed.

Thus, position of image = At 16.66 cm on opposite side of lens

Size of image = - 3.3 cm at the opposite side of lens

Nature of image – Real and inverted....
