Hey There! The right option MAY be (i) i.e Pascal's Principle.







HOPE THIS HELPS YOU

Angiosperms, ALSO called flowering PLANTS, have seeds that are enclosed within an ovary (usually a fruit), while gymnosperms have no FLOWERS or fruits, and have unenclosed or “naked” seeds on the surface of SCALES or leaves. Gymnosperm seeds are OFTEN configured as cones. The characteristics that differentiate angiosperms from gymnosperms include flowers, fruits, and endosperm in the seeds

The ANSWER is D.....

Animal CELL and Plant cell is from each other. THEREFORE the cell are made up of many kinds of organelles like tissue, DNA, nucleus,ETC..... .all the parts of our body is made up of tissue to cell ,cell to organs, organs to organ system and ORGANISM .so, these are called the STRUCTURAL and functional unit of life .

VENUS

Venus also has no natural SATELLITE. Earth : it rotates on its AXIS from WEST to EAST. It istilted on its axis by 23%.

The ANSWER is B) DECREASES

Exocrine: Pertaining to the secretion of a SUBSTANCE out through a DUCT. The exocrine glands include the salivary glands, sweat glands and glands WITHIN the GASTROINTESTINAL tract. Exocrine is as opposed to endocrine which refers to the secretion of a substance (a hormone) into the bloodstream. The exocrine glands are the "glands of external secretion" while the endocrine glands are "glands of INTERNAL secretion."

I think that black hole ATTRACTS everything into it because the GRAVITY is more in the black hole so that EVEN light cannot ESCAPE

There is a rare CHANCES of fish to LIVE in hot WATER coz only GOLD finh can live in hot water

Earth is a unique plant because it's the only plant we're EXISTING takes PLACE .The is the only planet in the solar system which contains WATER and air to breathe.So it is suitable for human beings to EXIST.

Pumice floats on WATER because it has an INCREDIBLY low density due to the air bubbles inside of it. As it is blown out of a volcano (EXTRUSIVE igneous), and dissolved gasses exsolve and more air gets into it before it HARDENS into pumice. The less DENSE air offsets the more dense rock, causing it to float.

Movement, PROTECTION are two functions.


hope it is USEFUL PL mark as a brain list PLEASE

The OPPOSITE force offered by the air on the BODY is :. here
a=9. 8
And mass=0. 05
so the air RESISTENCE offered on its SURFACE is
A×M=9. 8×0. 05
" " =0. 49N

The ANSWER is TRUE.

➡️Herbs, shrubs and trees in the FORESTS hold the top most layer FIRMLY by their roots. This does not allow natural forces like WIND and water to carry away the top most fertile layer of the soil easily. Hence, forests prevent soil EROSION.

A. ACTIVATION Function ....
Activation Function is the component of a Neural NETWORK where the TRUE VALUE of the INPUT is not observed.

Industrial electrical heaters are prone to ground leakage due to the breakdown orInsulation Breakdown contamination of INSULATORS. The use of NK Technologies’ Ground Fault Sensors enables early detection of leakage Currents as small as 5mA. The on/off output of the sensor can be used to trigger a CIRCUIT interruption DEVICE (for example a shunt-trip breaker) or a monitoring device like a PLC to determine the required action. Latching and auto-reset models are available in both normally energized and normally de-energized configurations suitable for most applications.

pumice has an AVERAGE POROSITY of 90% .so it can FLOAT on water.

Taxonomy is the branch of biology that CLASSIFIES all LIVING things
EXAMPLE .. an example of taxonomy is the way living being are divided up into kingdom ,PHYLUM,class,order,family,genus,species ETC.

Biodiversity is essential for ecosystem services and hence for human well-being. Biodiversity goes beyond the provisioning for material welfare and livelihoods to INCLUDE security, resiliency, social relations, health, and freedoms and choices. Some people have benefited over the last century from the conversion of natural ecosystems to human-dominated ecosystems and from the exploitation of biodiversity. At the same TIME, however, these losses in biodiversity and associated changes in ecosystem services have caused other people to experience DECLINING well-being, with some social GROUPS being pushed into poverty

Hope it helps u

The answer is No.

The 1st part of statement that "it burns vigorously" is True.

But the 2nd part of the statement "with no bead FORMATION" is False.

So the overall statement becomes FALSE.

Acrilon is used in Textile industry.

It is a Brand name of Acrylic FIBRE.

This fibre has MANY characteristics including softness and strength. It is also Wrinkle Resistant.

Acrolin burns quickly. It continues its burning even after the flame is removed.

This fibre usually shrinks and LEAVES a HARD plastic as a residue.

This remaining hard plastic is in shape of beads.

The word FILAMENT is from the Latin word FILUM, which means "thread." Filament, in FACT, can be a synonym for thread. In an incandescent light bulb, a fine wire called a filament is heated to high temperatures in a bulb that lacks oxygen to prevent the filament from catching fire as it is heated. The filament begins to glow and GIVES off light. The first filaments were made from carbon, now they are usually made from tungsten because of its high melting POINT.

Andromeda is ONE of the Greek constellations. It was NAMED afterAndromeda, the daughter of Cassiopeia and Cepheus in Greek MYTHOLOGY, who was chained and left for the sea MONSTER Cetus to EAT, and then saved by Perseus

Synthetic fibers are more durable than most natural fibers and will readily pick-up different DYES. In addition, MANY synthetic fibers offer consumer-friendly functions such as stretching, waterproofing and STAIN resistance. Sunlight, MOISTURE, and oils from human skin cause all fibers to break down and wear AWAY.

N-Butanol or n-butyl alcohol or normal butanol is a primary alcohol with a 4-carbon structure and the chemical formula C4H9OH. Its isomers include isobutanol, 2-butanol, and tert-butanol.,

Acetone (propanone) is the organic COMPOUND with the formula (CH3)2CO. It is a colorless, volatile, flammable liquid, and is the SIMPLEST and smallest ketone. Acetone is miscible with water and serves as an important solvent in its own right, TYPICALLY for CLEANING purposes in laboratories.

Well, I know of three adaptations. I LOVE MOUNTAIN GOATS!

Hello there!

Anyway, one of their adaptations is obviously their fur. They have thick fur that SHEDS sometime in the year (summer) that protects them from the cold because, well, they live in the mountains and higher altitudes equals lower temperatures because molecules and motion and other things. In addition, their bodies are rounded to conserve heat.

Another one of their adaptations are their feet, specifically their hooves. Their hooves are specially designed to grip the ground and they can TURN on a space the size of an envelope (I read that in one of those Canadian national parks)!

I think that their hooves have this little back bone that lets them grip the rock better or something. I forgot because it came from that same national park. I also saw a mountain GOAT while I was on this sky platform made of glass! Anyway, the point is, they have specially adapted hooves that allow them to grip surfaces better.

The LAST adaptation that they have to help them survive in their environment is their behavior. This at least protects them from predators. “Nannies” (MOTHER mountain goats) raise these

in the mountains/cliffs to protect them from animals like mountain lions and burrs. These herd animals are also adapted to jump really far and move really fast (at least for an animal in mountainous terrain) to escape those that hunt them. They live in non-permanent groups of about 100 goats. They don’t need much water, getting most of it from the foods that they eat, and their coats also camouflage them in their snowy environments.

I may have made a mistake somewhere. :(

MOUNTAIN GOATS ARE COOL

Teflon => high melting point , very lowest FRICTION and non reactive.

polystyrene => very light, can be blow up to her LARGE foam containing air bubble , in this FORM it is known as STYROFOAM or thermocol.

polythene => easily moulded, can be rolled into sheet , strong and flexible.

PVC => tougher than polythene , can be coated on a cloth base.

so, A <=> 4 , B <=> 1 , C <=> 2 , D <=> 3
