What are vitamins?
Vitamins are organic substances that are frequently classed as either fat-soluble or water-soluble. Vitamins including vitamin A, vitamin D, vitamin E, and vitamin K that dissolve in fat have a propensity to accumulate in the body. Examples of water-soluble vitamins include vitamin C and the B-complex vitamins, such as vitamin B6, vitamin B12, and folate, which must dissolve in water in order to be absorbed by the body and cannot be stored. Water-soluble vitamins are primarily eliminated in urine if the body does not use them.
Micronutrients including vitamins and minerals are required by the body for a variety of regular bodily functions. But since our bodies are unable to produce certain micronutrients, we must get them from the food we eat.

The first method used to extract previous temperatures from ice cores is the oxygen isotope ratio. Atoms of the exact same element that contain differing numbers of neutrons are known as isotopes. For at least the past 1 million years, Earth has gone through warm (interglacials) and cold (ice ages) periods on around 100,000-year cycles.
Oxygen isotope ratio phases are periodic changes in the proportion of the abundance of oxygen having atomic mass 18 to that of oxygen with atomic mass 16 found in various materials, such as calcite in sea core samples or polar ice. The number of protons, electrons, and neutrons in the nuclei of an element's isotopes are all the same, but the number of neutrons varies.
The Huronian (2.4 to 2.1 billion years ago), Cryogenian (850 to 635 million years ago), Andean–Saharan (460 to 430 mya), Karoo (360 to 260 mya), and Quaternary ice ages have all been noted by geologists (2.6 mya-present). The Eocene, which lasted for 53 to 49 million years, was the planet's warmest time in 100 million years.
Although pedogenesis processes can change the ratios, foraminifera and other species may be able to retain their initial isotopic ratios for many thousands of years. The orbital theory of the ice ages was discovered thanks in large part to research on the oxygen isotope ratios of foraminifera, which are still extensively employed in the study of rapid climatic change. The extensive record of global climate changes so over previous 100 million years has been revealed by compilations of oxygen isotopes from deep sea benthic foraminifers. In order to determine the extent of historical "greenhouse" warming and global ocean surface temperatures, planktonic foraminifer oxygen isotopes are employed to study the records of previous sea surface temperatures.

How do the winds and the ocean distribute heat throughout the biosphere?

One way that the world’s ocean affects weather and climate is by playing an important role in keeping our planet warm. The majority of radiation from the Sun is absorbed by the ocean, particularly in tropical waters around the equator, where the ocean acts like a massive, heat-retaining solar panel. Land areas also absorb some sunlight, and the atmosphere helps to retain heat that would otherwise quickly radiate into space after sunset.
When water molecules are heated, they exchange freely with the air in a process called evaporation. Ocean water is constantly evaporating, increasing the temperature and humidity of the surrounding air to form rain and storms that are then carried by trade winds.

Muscle cells generate atp by burning fuel (glucose) and oxygen in a process called aerobic respiration.
Aerobic respiration is the process by which organisms convert fuel, such as fats and sugars, into chemical energy by using oxygen.
During aerobic cellular respiration, glucose reacts with oxygen to form ATP, which the cell can use. As a byproduct, carbon dioxide and water are produced.
The overall equation for aerobic cellular respiration is:
C₆H₁₂O₆ + 6O₂ --------------------> 6CO₂ + 6H₂O + ATP
Cellular respiration
All cells use respiration to convert fuel into energy that can be used to power cellular processes.
