Fossil fuels such as gas, oil, and coal have what kind of energy?.
Answer:
chemical energy
Explanation:
The energy conversion goes from chemical energy stored in the fuels, to heat energy as it burns which is converted to kinetic energy as it drives large turbines and finally this is converted to electrical energy. The problem with burning fossil fuels is their effect on the environment.

Which statements is true about organ systems in the human body?
Choose 1 answer:
(A) if one organ system fails, a different organ system can take its place.
(B) all organ systems carry out the same functions in the human body.
(C) organ systems interact to allow the body to live and grow.
Answer:
(C) organ systems interact to allow the body to live and grow.
Explanation:
Organs depend on each other to carry out a certain function so the other organs can work.
Example- If the lungs of your body fails there will be no supply of oxygen. If there is no supply of oxygen there will not be enough blood for the heart to function.
If there is no oxygen there will be no oxygen or enough blood to flow to the brain.
Without the heart working the will be no blood to pump throughout the body.
Without the brain there will be no control to have the body and its organs to work properly.

What are the differences and similarities between cancer and an infectious disease? explain in detail.
Answer:
Cancer and infectious diseases are totally distinct categories of ailments. But at times they may present with similar symptoms and signs 1, 2. They are however treated with different modalities of therapy. Usually, infectious diseases do not carry the gloomy outlook of malignant tumors, although an infection may be fatal or develop at the end of treatment of a cancer.
Explanation:
We propose to disclose first degree analogous features between cancer and infectious diseases and to find out whether these similarities are superficial and negligible, due to the use of the same bodily pathways by the two categories of disease or if they represent significantly parallel characteristics. We have found several primary analogous features, predominantly regarding pathways of spread, but to some extent also concerning the interaction with the immune system. Some of the implications to our hypothesis are probably available in the recent literature, at the experimental or clinical levels. For example endostatin, an angiogenic inhibitor has been used to prevent promotion of metastasis in cancer and to reduce granulomas formation in schistosomiasis. An ECFR antagonist employed to restrain bronchial vessels proliferation in pseudomonas infection, has also been used for the treatment of lung cancer.
True or False: Contractions of smooth muscles are voluntary. It happens with your control.
Answer:
False
Explanation:
Smooth muscle is under autonomic nervous system control (which is something you cannot consciously control). Same thing is for cardiac muscle.
The only thing you can control is skeletal muscle like your hands and feet.

4. Define free energy, and explain how its change is calculated.
We can calculate the change in free energy for a reaction under nonstandard conditions by using the ΔG = ΔH - TΔS equation.
How do we calculate chnage in free energy?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.
Why is use of free energy?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.

3. Describe how nutrient cycles can interact in the cycling of matter:
Nutrients and matter in a biogeochemical cycle move through various spheres including the atmosphere, biosphere, hydrosphere and lithosphere.
What is nutrient cycles?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.

Predict what would happen to other organisms in an ecosystem in which all the decomposers went extinct?
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
Describe where genes are located and the function of genes.
According to the research, genes are structures located in the chromosomes whose function is the storage of genetic information.
What are genes?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.

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.
