Answer:

a Binomial Naming System. Scientists name animals and plants using the system that describes the genus and species of the organism. The first word is the genus and the second is the species. The first word is capitalized and the second is not,The science of classifying living things is called taxonomy. Linnaeus introduced the classification system that forms the basis of modern classification. Taxa in the Linnaean system include the kingdom, phylum, class, order, family, genus, and species,scientific name is used to name an organism to avoid misunderstandings caused when using the common name of organisms. An example of a scientific name is Homo sapiens to refer to modern human beings. It is written in italics and in which the initial letter of the genus name is capitalized,Scientists use scientific names for organisms so that it is universally understood what organism they are referring to.

Answer:

the other organism when they died with would not able to be decompose  the they dead bodies would be left to rot . And then they food cycle would not be able to grow .In short food chain would disssolve

Explanation:

When organisms die, decomposers break down the dead bodies and the nitrogen is released and another type of bacteria breaks it down into gaseous nitrogen. Without decomposers and other types of bacteria, the nitrogen cycle would not be maintained. Plants would die off and the food chain would dissolve. As plant are primary producers

Answer:

abiotic factors are water, air, soil, sunlight, and minerals. Biotic factors are living or once-living organisms in the ecosystem. These are obtained from the biosphere and are capable of reproduction. Examples of biotic factors are animals, birds, plants, fungi, and other similar organismsBiotic and abiotic factors are what make up ecosystems. Biotic factors are living things within an ecosystem; such as plants, animals, and bacteria, while abiotic are non-living components; such as water, soil and atmosphere. The way these components interact is critical in an ecosystem

Nutrients and matter in a biogeochemical cycle move through various spheres including the atmosphere, biosphere, hydrosphere and lithosphere.

Nutrients move through the ecosystem in the nutrient cycle or biogeochemical cycles. This cycle is a pathway by which a chemical element moves or recycles through the biotic and abiotic factors of an ecosystem.

It is inclusive of the biotic factors, or living organisms such as plants animals, and others, as well as abiotic or nonliving such as air, soil, and water.

it moves through abiotic and biotic elements such as water moves through water body to the atmosphere by evaporation and moves back to earth and hydrosphere by rain and also used by living organisms.

Thus, Nutrients and matter in a biogeochemical cycle move through various spheres including the atmosphere, biosphere, hydrosphere and lithosphere.

According to the research, genes are structures located in the chromosomes whose function is the storage of genetic information.

It is the minimum unit of genetic information that contains the DNA of a living being.

They are found within the chromosomes and each gene occupies a specific position, called a locus, which encodes a specific functional product, such as a protein.

Therefore, we can conclude that according to the research, genes are structures located in the chromosomes whose function is the storage of genetic information.

We can calculate the change in free energy for a reaction under nonstandard conditions by using the ΔG = ΔH - TΔS equation.

Change in gibbs free energy of any reaction will be calculated by uisng the below equation as:

ΔG = ΔH - TΔS, where

ΔH = change in enthalpy

T = temperature of reaction

ΔS = chnage in entropy

By putting all given values we can calculate the gibbs free energy of the reaction, and negative sign of energy shows the spontaneity of the reaction.

Hence by using the enthalpy, entropy and temperature we can calculate the free energy change.

Free energy refers to the energy in a system that is free to do work i.e. the internal energy minus any energy that is unavailable to perform work.

Free energy is used to determine how systems change and how much work they can produce. It is expressed in two forms: the Helmholtz free energy F, sometimes called the work function, and the Gibbs free energy G.

The free energy change of a reaction can be calculated using the following expression: ΔG∘=ΔH∘−TΔS∘. where ΔG=free energy change.
