Expain the process of nutrition takes place bud of hydra

Answer»

While feeding, Hydra extend their body to maximum length and then slowly extend their tentacles. DESPITE their SIMPLE construction, the tentacles of Hydra are extraordinarily extensible and can be four to five times the length of the body. Once FULLY extended, the tentacles are slowly manoeuvred around waiting for contact with a suitable prey animal. Upon contact, NEMATOCYSTS on the tentacle fire into the prey, and the tentacle itself coils around the prey. Within 30 seconds, most of the remaining tentacles will have already joined in the attack to subdue the struggling prey. Within two minutes, the tentacles will have surrounded the prey and moved it into the opened mouth aperture. Within ten minutes, the prey will have been engulfed within the body cavity, and digestion will have started. Hydra are able to stretch their body wall considerably in order to digest prey more than twice their size. After two or three days, the indigestible remains of the prey will be discharged through the mouth aperture VIA contractions.

Describe the different ways of making fabric from fibre?

Answer»

Here are some steps for cotton-

Cultivation of cotton

Cotton is CULTIVATED in black clayey soil. It needs warm climate. The sowing of cotton crop is done in early spring. Cotton plants are bushy and about 1-2 meters tall. The plants start flowering in about 60 days and give whitish - yellow flowers. The flowers TURN reddish in a few days. Flowers slowly grow into spherical walnut-like structures. These are called cotton ball. Fibres of cotton grow on these seeds. After some TIME green cotton balls turn brown. At maturity, the cotton bolls burst open and the white cotton fibre can be seen.
Ginning: The cotton picked up from the plants has seeds in it. The process of removing cotton seeds from pods is called ginning. Ginning was traditionally done by hand. Now-a-days, machines are used in ginning.
Spinning: The process of making yarn from fibre is called spinning. The raw cotton is supplied to industry in the form of bales.

Steps in making cotton yarn

Weaving: The process of arranging two sets of yarn together to make a fabric is called weaving. The big reels of yarn are called bobbins. These bobbins are used for weaving the cloth. Cloth is WOVEN on LOOMS. After that they bleached and dyed to give a finish.
Knitting: Knitting can be done by hand and machine. Just two yarns are used in knitting, while more than two yarns are used in weaving. Sweater, socks, scarf and caps are knitted from the wool.
Uses of cotton: Cotton is mostly used for making clothes of various kinds. Examples: towels, bed-sheet, curtains, saris.

What is difference between oscillatory motion and linear motion

Answer»

What happens when you displace a swing from it's position of REST ? It starts moving from one side of the rest position to the other and back. It keeps OSCILLATING between the TWO extreme positions, moving back and forth. This REPEATED back and forth movement about the rest position is called oscillatory motion.

When a body moves along a straight line, it is said to be linear or rectilinear motion.
A car moving along a straight road, a train moving on straight track, a child going down to a slide, an arrow shot from a bow, a group of marching soldiers and a ball dropped from a height are all examples of linear motion.

Why crop field is known as an artificial ecosystem but pond is not

Answer»

An agricultural FIELD is considered to be an artificial ecosystem DUE to following reasons. It is man made ecosystem hence considered as artificial ecosystem. It has all the components of the ecosystem. Abiotic fctors include air, WATER, soil etc. Biotic factors include all the living organisms like plants, animals and microbes. It comprises various phenomena such as flow of energy,  food CHAINS, food webs etc. For example, an agriculturist cultivating rice can culture the fish as well in the same farm. Water is made to stand in the rice field which allows the growth of planktons. Fish feed on these planktons. Fish are fed by cranes. Cranes are fed by snakes.Planktons-----> Fish ------> Cranes------> Snakes

write the molecular formula of the second and third member of the homologous series whose first member is ethene

Answer»

As the first member is ethane,

It has the suffix “ane” so this MEANS that the compound is an alkane

The 2ND member of the SERIES will be propane

The general formula for alkane is CnH2n+2CnH2n+2

So the n is the number of CARBON atoms. The number of Carbon atoms in propane is 3

The formula is C3H8C3H8

The 3rd member of the homologous series will have 4 carbon atoms

The name of the compound is butane

The formula is C4H10

a body has a weight of 10 kg on the surface of earth what will be its mass and weight when taken to the centre of earth

Answer»

Hello Mate!

To get the answer we must know that what MASS and weight actually are. The two terms whuch are used in OLACE if each other are scientifically different.

Mass is the content inside body or in other WORDS its measure if inertia. It remains constant.

Weight is NONE other than gravitational firce with which we are attracted towards GROUND. Weight of body is constant and product of its mass and acceleration. Hence Weight and force have same formulas.

= Since we know that gravitational force is 0 in the core of earth so weight if body will also be zero but mass will remain same.

Have great future ahead!

Advantages and disadvantages of synthetic dye

Answer»

Advantages....
1- They do not shrink.
2- They are quick drying and need very little or no ironing.
3- They last longer as compared the fabrics made from natural FIBRES.

Disadvantages...
1- Synthetic fibres do not absorb water or sweat. In hot and humid weather THEREFORE the clothes made of synthetic fibre stick to the body and make the wearer uncomfortable.
2- Synthetic fibres melt and burn easily.
3- Synthetic fibres on CATCHING fire shrink forming beads which stick to the skin. Therefore it is not advisable to use clothes made from synthetic fibres while working near flam/fire, such as,in kitchen.
4- Synthetic fibres are nonbiodegradable . Therefore they cause SOIL pollution.

cheap non polluting fuel with a very high calorific value was developed by a scientist it had an ignition temperature of 20 degree celsius is it a good fuel give reason

Answer»

Yes, of course a fuel which has such a low IGNITION TEMPERATURE then it surely is a very good fuel. Being SOLD in a reasonable price, is ALSO one good feature of it. If a fuel has low ignition temperature then it would produce very less amount of POLLUTANTS or residues which would not cause air pollution. One example of such a fuel is CNG...

Explain the phenomena of biological magnification. how does it affect the organisms of different tropic levels, particularly the tertiary consumers??

Answer»

Biomagnification, also known as BIOAMPLIFICATION or biological magnification, is the increasing concentration of a substance, such as a toxic CHEMICAL, in the tissues of tolerant organisms at successively higher levels in a food chain. This INCREASE can occur as a result of:

Persistence – where the substance cannot be broken down by environmental processes

Food chain energetics – where the substance's concentration increases progressively as it moves up a food chain

Low or non-existent rate of INTERNAL degradation or excretion of the substance – often DUE to water-insolubility

45.

Explain the three ways in which glucose is broken down to get energy

Answer»

Answer:-

break down of pyruvate takes place in different manners in different organisms.

(i) Anaerobic respiration: This process takes place in absence of oxygen e.g., in YEAST during fermentation. In this case pyruvate is converted into ethanol and carbon dioxide.

(ii) Aerobic respiration: In aerobic respiration break down of pyruvate takes place in PRESENCE of oxygen to give RISE 3 molecules of carbon dioxide and water. The release of energy in aerobic respiration is much more than anaerobic respiration.

(iii) Lack of oxygen: Sometimes, when there is lack of oxygen, especially during vigorous activity, in our muscles, pyruvate is converted into LACTIC acid (3 carbon molecule compound). Formation of lactic acid in muscles causes cramp.

Why are places near the equator always hot

Answer»

Because equator have high temperature .
The MAJOR factor is that while the sun is overhead at the equator, it is at a rather SLANT ANGLE at the poles. This effect can be demonstrated using a torch, which can be taken as the sun.. so places NEAR equator ALWAYS hot ...
