When energy from food is in short supply, the body?
When the energy from the food is in short supply, the body breakdown its stored triglycerides and releases fatty acids for energy.
What is Energy?Energy is the ability to do work which exists in different forms. It follows the law of conservation which states that Energy is neither created nor destroyed, it can be transferred from one form to another.
Humans obtain energy from these molecules -carbohydrates, lipids, and proteins where the potential chemical energy of these molecules is transformed into other forms, such as thermal, kinetic, and other chemical forms of the energy.
These 3 molecules are called as fuel molecules. The energy of the food is expressed in Calorie(C). Major source of energy is Carbohydrates but when there is shortage in food supply lipids provides the energy.

the tricuspid is located between the left atrium and ventricle. a. true b. false
False, the tricuspid is not situated between the left atrium and ventricle; rather, it is situated between the right atrium and the right ventricle, which is located between the left atrium and the left ventricle.
The tricuspid valves support ensuring that blood flows appropriately and in the appropriate direction. The right atrium and right ventricle are connected by the tricuspid valve, which controls blood flow. Blood cannot flow backward between those two chambers as a result. Tricuspid valve opening results from right atrium filling, which allows blood to enter right ventricle.
One of the two sizable chambers at the base of the heart, called ventricles, is responsible for collecting and releasing blood into the lungs and other peripheral regions of the body.

3. This organism will help remove the excess nitrate from the water
By lowering the amount of water that leaves the site, recycling drainage water can reduce or possibly potentially eliminate nitrate loss.Although the potential for recycling drainage water is considerable, in most cases the size of the water storage reservoir will be the limiting factor.
This organism will help remove the excess nitrate from the water?
Nitrate from drinking water can be eliminated via distillation, ion exchange units, or reverse osmosis.Keep in mind that boiling water does not get rid of nitrates and is not a substitute for treatment.In actuality, when water evaporates, nitrate concentrations rise.An ion exchange system works similarly to a water softener seen in homes. Although adding plants is a fantastic long-term nitrate reduction method, it is best to take immediate action if your water currently has high nitrate levels. Strong anionic resin in the form of Cl- can be used to remove nitrates through ion exchange.Nitrates can also be effectively removed by reverse osmosis, albeit the molecule's hydrophilic characteristics prevent an ideal removal.In municipal waste water treatment facilities, biological denitrification is employed. Inorganic nitrates, which are composed of nitrogen and oxygen, can be found in the environment both naturally and artificially.The atmosphere, the soil, and the water on earth all contain nitrates.They are extremely soluble in water and readily biodegradable.Animal waste, plant decay, and agricultural byproducts all produce nitrates.Nitrates may enter groundwater supplies due to rainfall, flooding, and soil erosionOne of the most crucial nutrients for healthy plant and crop growth is nitrogen.One of the components of the chlorophyll molecule, which enables plants to produce their own food through the process of photosynthesis, is nitrogen.Nitrates are used as fertilizers for lawns, gardens, flowers, and crops to provide plants this inorganic energy. By using ion exchange resin, distillation, or reverse osmosis, nitrates can be taken out of water.Nitrates are a pollutant that is challenging to remove from water.Sediment filters, carbon filters, and the hollow fiber membrane of an ultrafiltration system will not be able to extract nitrates.In a similar vein, nitrates cannot be reduced or eliminated by a conventional ion exchange water softener.Installing an anion resin tank at the point of entry is the most popular and efficient method of completely eliminating nitrates from your home.Installing an under-sink reverse osmosis system is advised if you only wish to remove nitrates from your drinking and cooking water.Additionally, you can use a water distiller to remove nitrates from a little amount of water at a time.To learn more about nitrate refer

what two lines of evidence support how meiosis may have evolved from prokaryotic conjugation?
Meiosis has evolved from prokaryotic conjugation because it is involved in sexual cycle in eukaryotes as transformation is in prokaryotes.
Meiosis and transformation are essential phases of eukaryotic and bacterial sexual cycles, respectively. Both procedures are intricate modifications that are encoded by numerous genes. In the process of meiosis, non-sister homologous chromosomes (resulting from the fusing of gametes from different parents) align and go through genetic recombination in the nucleus of diploid eukaryotic cells of the germ line. A haploid gamete receives the recombined genome after that, and when it fuses with another gamete, it produces a diploid offspring cell.
Similar to meiosis, bacterial transformation happens inside a bacterial cell when non-sister homologous chromosomes (or portions of chromosomes) from separate parent cells align and undergo genetic recombination. A new bacteria is created from the recombined DNA.
