ADPShort for adenosine diphosphate. An organic compound that is composed of adenosine and two phosphate groups

Adenosine triphosphate is a complex organic chemical that provides energy to drive many processes in living cells, e.g. muscle contraction, nerve impulse propagation, chemical synthesis.

Adenosine triphosphate, also known as ATP, is a molecule that carries energy within cells. It is the main energy currency of the cell, and it is an end product of the processes of photophosphorylation (adding a phosphate group to a molecule using energy from light), cellular respiration, and fermentation. All living things use ATP. In addition to being used as an energy source, it is also used in signal transduction pathways for cell communication and is incorporated into deoxyribonucleic acid (DNA) during DNA synthesis.

ATP stands for Adenosine triphosphate

Adenosine Tri- Phosphate

Adinosine tri-phosphate

Adenosine Tri Phosphate ,--it's a high energy bonds containing molecule and is most common among the energy providing molecules in biological reactions.

When one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released, andATPisconvertedto adenosine diphosphate (ADP).

5)ATP is Adenosine triphosphate, it is the energy currency of the cell.

Farmers interested in long-term sustainability often prioritize caring for the soil, because they recognize that a healthy soil promotes healthy crops and livestock. Maintaining soil functioning often means a focus on maintaining or even increasing soil organic matter.

Rotating crops and embracing diversity. Planting a variety of crops can have many benefits, including healthier soil and improved pest control. Crop diversity practices include intercropping (growing a mix of crops in the same area) and complex multi-year crop rotations.

Planting cover crops.Cover crops, like clover or hairy vetch, are planted during off-season times when soils might otherwise be left bare. These crops protect and build soil health by preventing erosion, replenishing soil nutrients, and keeping weeds in check, reducing the need for herbicides.

Over the last century, the global population has quadrupled. In 1915, there were 1.8 billion people in the world. Today, according to the most recent estimate by the UN, there are 7.3 billion people — and we may reach 9.7 billion by 2050. This growth, along with rising incomes in developing countries (which cause dietary changes such as eating more protein and meat) are driving up global food demand.

Food demand is expected to increase anywhere between 59% to 98% by 2050. This will shape agricultural markets in ways we have not seen before. Farmers worldwide will need to increase crop production, either by increasing the amount of agricultural land to grow crops or by enhancing productivity on existing agricultural lands through fertilizer and irrigation and adopting new methods like precision farming.

However, the ecological and social trade-offs of clearing more land for agriculture are often high, particularly in the tropics. And right now, crop yields — the amount of crops harvested per unit of land cultivated — are growing too slowly to meet the forecasted demand for food.

Many other factors, from climate change to urbanization to a lack of investment, will also make it challenging to produce enough food. There is strong academic consensus that climate change–driven water scarcity, rising global temperatures, and extreme weather will have severe long-term effects on crop yields. These are expected to impact many major agricultural regions, especially those close to the Equator. For example, the Brazilian state of Mato Grosso, one of the most important agricultural regions worldwide, may face an 18% to 23% reduction in soy and corn output by 2050, due to climate change. The Midwestern U.S. and Eastern Australia — two other globally important regions — may also see a substantial decline in agricultural output due to extreme heat.

Objectives and advantages of biodiversity conservation

Conservation of biological diversity leads to conservation of essential ecological diversity to preserve the continuity of food chains.

The genetic diversity of plants and animals is preserved.

It ensures the sustainable utilisation of life support systems on earth.

It provides a vast knowledge of potential use to the scientific community.

A reservoir of wild animals and plants is preserved, thus enabling them to be introduced, if need be, in the surrounding areas.

Biological diversity provides immediate benefits to the society such as recreation and tourism.

Biodiversity conservation serves as an insurance policy for the future.

Biodiversityis the variety andvariabilityoflife on Earth. Biodiversity is typically a measure of variation at thegenetic,species, andecosystemlevel.[1]Terrestrial biodiversity is usually greater near theequator,[2]which is the result of the warmclimateand highprimary productivity.[3]Biodiversity is not distributed evenly onEarth, and is richest in the tropics. These tropical forest ecosystems cover less than 10 percent of earth's surface, and contain about 90 percent of the world's species.[4]Marine biodiversityis usually highest along coasts in the WesternPacific, wheresea surface temperatureis highest, and in the mid-latitudinal band in all oceans. There arelatitudinal gradients in species diversity.[5]Biodiversity generally tends to cluster inhotspots,[6]and has been increasing through time,[7][8]but will be likely to slow in the future.[9]

Greywater(also spelledgraywater,grey waterandgray water) orsullage, "foul water"is allwastewatergenerated in households or office buildings from streams without fecal contamination, i.e. all streams except for the wastewater from toilets. Sources of greywater include,sinks,showers,baths, clotheswashing machinesor dish washers. As greywater contains fewerpathogensthan domestic wastewater, it is generally safer to handle and easier to treat and reuse onsite fortoilet flushing, landscape or cropirrigation, and other non-potable uses.

The grey matter is mainly composed of neuronal cell bodies and unmyelinated axons. Axons are the processes that extend from neuronal cell bodies, carrying signals between those bodies. In the grey matter, these axons are mainly unmyelinated, meaning they are not covered by a whitish-colored, fatty protein called myelin.

Fleming's left-hand rule is used for electric motors, while Fleming's right-hand rule is used for electric generators. In an electric generator, the motion and magnetic field exist (causes), and they lead to the creation of the electric current (effect), and so the right hand rule is used.

Plant hormonesare known asphytohormonesin botanical terms. They are chemicals just like animal hormones that help in the growth, development, andfunctioningof plants.

These hormones help in regulation of the plant body by responding to the various signals from the plant and environment. The hormones are regulated in different tissues during the different development stages.

There are five major hormones which are auxin, cytokinin, gibberellin, abscisic acid, and ethylene. Each hormone differs in its effects. The auxins, gibberellins, and cytokinins act as growth stimulators, whereas, abscisic acid and ethylene act as growth inhibitors. Plant hormones are simple in their structure as compared to those of animals or humans. There are no specific or specialized glands that produce these hormones. In fact, they are synthesized anywhere in the plant and act on any part as their target. Besides the hormones, there are manyplant growth factorsthat affect the function and growth of plants

plant hormones or phytohormones are organi substances produced in higher plants . They control growth and other physiological functions of the plants. these are required in very small amount.

The 2 mainthyroid hormonesare T3 (triiodothyronine) and T4 (thyroxine). T3 and T4 regulate your body's temperature, metabolism and heart rate. The amount ofthyroid hormones secretedis controlled by anotherhormone, calledthyroidstimulatinghormone(TSH), which is released from the pituitary gland in your brain.

Thepituitary glandis a tiny organ, the size of a pea, found at the base of the brain. As the “mastergland” of the body, it produces many hormones that travel throughout the body, directing certain processes or stimulating otherglandsto produce other hormones

Hormones produced by the pituitary gland. Adrenocorticotrophic hormone (ACTH) Thyroid-stimulating hormone (TSH) Luteinising hormone (LH) Follicle-stimulating hormone (FSH) Prolactin (PRL) Growth hormone (GH) Melanocyte-stimulating hormone (MSH)

Photosynthesis helps to balance oxygen and carbon dioxide in the air. Oxygen gas is produced during photosynthesis which animals breathe in. Animals breathe out CO2 and the plants need this CO2 for photosynthesis. So, the levels of CO. and 02 are balanced in the air. Nitrogen gas is also circulated continuously between living and nonliving components of the biosphere. It also enters through the producer level through various processes and get transferred to other trophic levels. Finally, decomposers act on dead bodies of living organisms and the inorganic nitrogen enters the nature again.
