Muscles move body PARTS by contracting and then relaxing. Muscles can pull bones, but they can't push them back to the original position. So they work in pairs of flexors and extensors. The FLEXOR contracts to BEND a limb at a joint.Together with the skin and associated fascia and muscles, the rib cage makes up the thoracic wall and provides attachments for the muscles of the neck, thorax, upper abdomen, and back. The rib cage has a major function in the respiratory system.hope it helpsplz mark as the BRAINLIEST answer

1. if freshly harvested grains are stored without trying they might get spoilt or attacked by MICROORGANISMS losing their germination capacity hands before storing them the grains are populated write in the sun to reduce moisture on them the these presents the attack by INSECTS pest bacteria and fungi2. it is very important to sow seeds at the correct DISTANCE from each other because PLANTS need some space to grow up and to stretch their branches and they will get sufficient amount of light and nutrition and there will be no competition for food and nutrients.3. the preparation of soil is very important because the soil should be even nutritional so when we prepare the soil the Newton's will be evenly mix and become more nutritional the quality of clans also depends on the composition of soil the fertile soil is suitable for the CROPS to grow in proper way.

If Earth doesn't have friction the following problems will occur: No LIVING being can walk;because the MOMENT they apply force they will slip. If a body is in motion it will continue to be in motion as there will be no OPPOSING force.Explanation:PLEASE follow me mark as BRAINLIEST........

ldwide disruption caused by the COVID-19 pandemic has resulted in numerous impacts on the environment and the climate. The considerable decline in planned travel[2] has caused many regions to experience a large drop in air pollution. In China, lockdowns and other measures resulted in a 25 per cent reduction in carbon emissions[3] and 50 per cent reduction in nitrogen oxides emissions,[4] which one Earth systems scientist estimated may have saved at least 77,000 lives over two months.[5][6] Other POSITIVE impacts on the environment include governance-system-controlled investments towards a sustainable energy transition and other goals related to ENVIRONMENTAL protection such as the European Union's seven-year €1 TRILLION budget proposal and €750 billion recovery plan "NEXT Generation EU" which seeks to reserve 25% of EU spending for climate-friendly EXPENDITURE

Food is obtained from animals for which animals are reared.This is CALLED ANIMAL husbandryMany PEOPLE living in the coastal AREAS consume fish as a major part of a diet.We have just seen that the process of crop production involves a number of steps like selection of seed ,SOWING,etc. Similarly animals reared at home in harm's have to provided with with proper food, shelter.Hope it will help you ..........

follow me mark as brainestExplanation:Earth is one special PLANET.It has liquid water, plate tectonics, and an atmosphere that shelters it from the WORST of the sun's rays. But many scientists agree our planet's most special feature might just be us."It?s the only planet we know of that has life," said Alan Boss, a planet formation theorist at the Carnegie Institution of Washington in Washington, D.C.Though other bodies in our SOLAR system, such as Saturn's moon Titan, seem like they could have once been hospitable to some form of life, and scientists still have hope of eventually digging up microbes beneath the surface of Mars, Earth is still the only world known to support life."So far, we haven't found it anywhere else," said Alex Wolszczan of Pennsylvania State University, who co-discovered the first planets beyond our solar system. He agreed that life was Earth's single most impressive characteristic.None of this is a revelation, but understanding what's special about Earth is crucial for finding other planets out there and predicting what they might be like.The fact that Earth hosts not just life, but intelligent life, MAKES it doubly unique. And the planet's intelligent life (humanity) has even developed rockets that enable travel beyond the planet, said Gregory Laughlin, astrophysicist and planet HUNTER at the University of California, Santa Cruz.

of silkworms: A female SILK moth lays hundreds of eggs at a time. The eggs are stored by the farmers at SUITABLE temperature and humidity under hygienic CONDITIONS. When the eggs hatch, silkworms COME out of the eggs. The silkworms are fed mulberry leaves. After 25-30 days, the silkworms stop eating and get ready to spin cocoons. The silkworms enclose themselves completely inside the silken cocoons in two or three days.See the image

tion:ERIS, the largest known dwarf planet, was first detected in data collected in October of 2003. It was not identified until January of 2005. MIKE Brown and his team of astronomers discovered what was considered to be the 10TH planet while doing observations at the Palomar Observatory in California. At approximately 10 billion kilometers from the Sun, it is roughly 3 times FARTHER out than PLUTO.

rogen cycle is a repeating cycle of processes during which nitrogen moves through both living and non-living things: the atmosphere, soil, water, PLANTS, animals and bacteria. In order to move through the different parts of the cycle, nitrogen must CHANGE forms. In the atmosphere, nitrogen exists as a gas (N2), but in the soils it exists as nitrogen oxide, NO, and nitrogen dioxide, NO2, and when used as a fertilizer, can be FOUND in other forms, such as ammonia, NH3, which can be processed even further into a different fertilizer, ammonium nitrate, or NH4NO3.There are five stages in the nitrogen cycle, and we will now discuss each of them in turn: fixation or volatilization, mineralization, NITRIFICATION, immobilization, and denitrification. In this image, microbes in the soil turn nitrogen gas (N2) into what is called volatile ammonia (NH3), so the fixation process is called volatilization. Leaching is where certain forms of nitrogen (such as nitrate, or NO3) becomes dissolved in water and leaks out of the soil, potentially POLLUTING waterways.Hope It Helps You Follow Me #itzcutiepie

Explanation:STARS EXIST in a range of colors: red, orange, yellow, green, WHITE and blue with red being the coolest and blue being the hottest. A star's color INDICATES it's temperature, composition and relative distance from earth. Its LUMINOSITY indicates its size, the brighter it is, the larger it is.

Synodic monthExplanation:The time interval between a FULL (or new) moon and the NEXT REPETITION of the same PHASE, a synodic month, averages about 29.53 days. Therefore, in those lunar calendars in which each month begins on the DAY of the new moon, the full moon falls on either the 14th or 15th day of the lunar month.
