In many ways. For example, forensic scientists may use them to examine blood, dust, fibers, and other trace materials at a crime scene. They can also be used to identify minerals or particles.

A marine biologist measured the amount of heat radiated from an aquarium over the course of an experiment. His measurements are
Andrews [41]

Answer:

The correct answer is - A closed system exchanges all of its energy with its surroundings, and the scientist only measured the exchange of heat.

Explanation:

The amount of heat radiated is measured and analyzed by the marine biologist in this given experiment from an aquarium and on the basis of data the diagram is represented that states that the radiated energy is not constant over time and there are fluctuations.

It can not be considered as a closed system as energy is still exchange with the surrounding system, however, mass is not exchange but still, it cannot be called a closed system.

Make an inference about what happens to the matter and energy during the formation and breakdown of a complex carbohydrate molec
Semenov [28]

Answer:

The breakdown of carbohydrates in the cell during cellular respiration does not change the matter or energy in the molecule. Actually, the matter in the energy molecule, which is the number of atoms and molecule, remains the same and are only transferred to make other molecules (remember that in a chemical reaction, the number of atoms on the reactants side must balance with those of the products). The energy in the bonds of the molecule, as they are broken down by metabolic enzymes, are what is transferred to ATPs. This process is not efficient as most energy is lost as heat. The energy in the ATPs is used in catabolic process like the formation of carbohydrates in the Calvin cycle of plants. Catabolic processes reduce entropy - & increase Gibbs free energy - hence require energy.

Ultimately, no energy or matter is destroyed or made, it is only transferred, hence observing the first law of thermodynamics.

Energy in the body is stored through glycogenesis where glycogen is formed from excess glucose and stored in tissues. When energy is required, this glycogen is broken down back to glucose through glycogenolysis and it can be used in cellular respiration.

Why do eukaryotic cells undergo mitosis?
vodomira [7]
Hello

Most eukaryotic cells that are not involved in the production of gametes undergo mitosis. These cells, known as somatic cells, are important to the survival of eukaryotic organisms, and it is essential that somatic parent and daughter cells do not vary from one another.

Hope this helps

What would happen to the body if the body temperature continued to decrease during the tenth hour instead of leveling off
Sergeu [11.5K]
There are several reasons why the body temperature falls continuously just like when you are exposed to an extreme cold weather or wearing wet clothing for a long time. This abnormality state of the body temperature can lead into some potential diseases and disorders like infection, insomnia, stress and sepsis.
