Answer:

Good examples are the reshaping of a coastline by a tsunami, deposition of mud by a flooding river, the devastation wrought by a volcanic explosion, or a mass extinction caused by an asteroid impact. The modern view of uniformitarianism incorporates both rates of geologic processes.

Explanation:

the theory that changes in the earth's crust during geological history have resulted from the action of continuous and uniform processes.

Uniformitarianism, also known as the Doctrine of Uniformity or the Uniformitarian Principle, is the assumption that the same natural laws and processes that operate in our present-day scientific observations have always operated in the universe in the past and apply everywhere in the universe

Answer:

Aerobic respiration generates a high amount of energy compared to anaerobic respiration.

Explanation:

Yeast is a unicellular organism that belongs to the kingdom FUNGI. Yeast is a phenomenal organism being that it is capable of both aerobic respiration and anaerobic respiration depending on whether there is availability or not of oxygen.

Yeast undergoes a type of anaerobic respiration called FERMENTATION in the absence of oxygen but when oxygen is present, it undergoes aerobic respiration. Note that aerobic respiration, which includes glycolysis, Krebs cycle, and oxidative phosphorylation, produces the highest amount of energy in form of ATP. This amount ranges from 32-34 ATP molecules. This is the major reason why aerobic respiration is advantageous over the anaerobic respiration.

Rubidium is a soft, white metal that reacts with water similarly to sodium and potassium, but the reaction is much more violently exothermic.

When one or more chemicals are converted into one or more other chemicals, a chemical reaction occurs.

A chemical reaction is a practice that reverts one or even more substances, renowned as reactants, to one or even more various compounds, widely recognized as products.

Chemical elements or compounds are examples of substances.

Living things (cells, animals, humans, and insects) use chemical reactions to grow, develop, reproduce, and adapt.

Combination, decomposition, single-replacement, double-replacement, and combustion are the five basic types of chemical reactions.

Analyzing the reactants and products of a specific reaction will allow you to categorize it.

Rubidium is basically a soft, white metal that reacts with water in the same way that sodium as well as potassium do, but the reaction is much more exothermic.

Thus, rubidium and sodium are the two other elements that react the same way in a chemical reaction as potassium.

Answer:

Echinoderms play numerous ecological roles. Sand dollars and sea cucumbers burrow into the sand, providing more oxygen at greater depths of the sea floor. This allows more organisms to live there.

Explanation:

They are also economically important to humans due to their use in scientific research and education and also for food.

Answer:

Echinoderms play numerous ecological roles.

Answer:

Due to the law of independent assortment

Explanation:

In diploid species like humans, all somatic (body) cells have two complete sets of chromosomes, one chromosome inherited from the maternal gamete and one chromosome inherited from the paternal gamete. Each one of the homologous chromosomes contains one copy of each gene, or allele, such that one allele is inherited from each parent. According to the law of independent assortment, maternal and paternal chromosomes are independently assorted during meiosis, which means that different genes localized on different chromosomes are randomly distributed into gametes. In consequence, alleles of different genes are transmitted from parents to offspring independently of one another.

Answer:

by an epigenetic mechanism

Explanation:  

Epigenetics can be defined as the study of mitotically heritable gene expression changes that do not involve alterations in the DNA sequence. There are three different epigenetic modifications that work together either to activate or repress gene expression: DNA methylation, histone modifications (e.g., methylation, acetylation, phosphorylation, etc) and regulatory non-coding RNAs (e.g., long non-coding RNAs, microRNAs, piwi-RNAs, etc). Deacetylases are enzymes that play roles in epigenetic gene regulation by removing acetyl groups from lysine (K) residues located at the N-terminal end of histones H3 and H4. Histone deacetylation modifies the structure of the chromatin, thereby activating or suppressing gene expression in a context-dependent manner.

Explanation:

Seismic waves are elastic waves that are able to propagate within the subsurface.

The travel - time to depth expressed in form of velocity is used to determine the composition, thickness and density of the interior of the earth.

Question: "What is the difference between a detritivore and a decomposer?"

Answer: "Well, detritivores are known for feeding on dead 'organic matter'. Meanwhile, decomposers (like earthworms for example) actually break down all dead or decaying organisms. This being said, I would say out of the given options above, Option B would be the best answer."

Based on the explanation given, the difference between a detritivore and a decomposer is that while detritivores feed on dead organic matter, decomposers actually break down dead or decaying organisms externally.

A detritrivore is an organism which feeds on dead or decaying organic matter, especially plant detritus.

An example of a detritrivore is dung flies, millipedes, etc.

A decomposer is an organisms which breaks down dead or decaying organic matter.

Examplesof decomposers are bacteria and fungi.

The key difference between a detritivore and a decomposer is that while detritivores feed on dead organic matter, decomposers actually break down dead or decaying organisms externally.

Therefore, based on the explanation given, the difference between a detritivore and a decomposer is that while detritivores feed on dead organic matter, decomposers actually break down dead or decaying organisms externally.

Explanation:

Answer:

Energy is stored as potential energy

Explanation:

Candy bars are primarily made of glucose (and other types of sugars), which contain many covalent bonds that store potential energy. The reason why a candy bar can sit still on the shelf is because covalent bonds are very stable. However, when you eat the candy bar, your body has enzymes that can metabolize the candy, breaking down the covalent bonds and releasing all that "trapped" energy inside.

Answer:

Sunlight energy

During Photosynthesis, Sunlight energy is used to break water down into oxygen and hydrogen.

Answer:

Some of the electrical energy is destroyed.

Explanation:

some of the electrical energy is destroyed because If the excess energy goes beyond the tolerance of the devices, they will overheat and/or burn (cause damage). ... If there is no interest in saving the extra energy, it can be "dumped" into an appropriate load and converted to heat.

When a lightbulb burns out, then that is when all of the electrical energy got desroyed, and that is why it happens over time

The statement that best explains this is some electrical energy is destroyed. The correct option is A.

Electrical energy is kinetic energy generated by moving electric charges. The amount of energy relies on the charge's speed; the faster it moves, the more electrical energy it carries.

Some electrical energy is destroyed because if the extra energy exceeds the devices' tolerance, they will overheat and/or burn (causing damage). If there is no desire to save the excess energy, it can be “dumped” onto a suitable load and transformed into heat.

When a lightbulb burns out, all of the electrical energy is destroyed, which is why it happens over time.

Therefore, the correct option is A. Some electrical energy is destroyed.
