Which principle allows us to assign dates to events on the geologic time scale?
faunal succession
extinction
radioactive decay
relative dating
The principle that allows us to assign dates to events on the geologic time scale is radioactive decay. Therefore, option (C) is correct.
What is radioactive decay?This theory is based on the observation that certain isotopes of elements are inherently unstable and, as a result, decay over time, giving rise to the formation of new isotopes or elements. Scientists are able to determine the age of a sample by measuring the ratio of parent to daughter isotopes in the sample. This, in turn, enables them to assign dates to events on the geologic time scale.
The method of determining the age of rocks, minerals, and other geological materials is known as radiometric dating, and it is utilized extensively in the field of geology as well as in other earth sciences.

How are food webs used to help explain ecosystem interactions?
Food webs used to help explain ecosystem interaction as the food web shows the flow of energy from one organism to another.
What is Food web?Food webs have been defined as important conceptual tools for delineating feeding relationships among species within a community, revealing species interactions and community structure, and understanding the dynamics of energy transfer in an ecosystem.
It is defined as a graphical representation of the natural interconnection of food chains and what-eats-what in an ecological community. Food web is also called consumer-resource system.
Example of Food web is Falcon eats snake, which has eaten frog, which has eaten grasshopper, which has eaten grass. A food web shows the many different pathways where plants and animals are connected
Thus, Food webs used to help explain ecosystem interaction as the food web shows the flow of energy from one organism to another.

Your answer:

Answer:
A poor insulator!
Explanation:
Since Iron has molocules so close together it CAN conduct heat very well. Because of this A and C are not relavent options.
Thermodynamics is "the branch of physical science that deals with the relations between heat and other forms of energy (such as mechanical, electrical, or chemical energy), and, by extension, of the relationships between all forms of energy."
Due to the fact iron is a strong conductor, it IS bound to the law od thermodynamics. It's a very easy conceept to understand, you just have to pay attention a little bit and searching up definitions can help too!

How can the history of Mount Rainier's eruptions help you decide whether hiking around Mount Rainier is safe?
The history of Mount Rainier's eruptions can help you decide whether hiking around Mount Rainier is safe by providing information about the volcano's past activity, eruption patterns, and potential hazards.
The history of Mount Rainier's eruptions provides valuable insights into the volcano's behavior and can help assess the safety of hiking around the area. By studying the volcano's eruption history, scientists and authorities can gather data on the frequency, magnitude, and types of eruptions that have occurred in the past.
This information is crucial for understanding the potential hazards associated with the volcano. For example, if Mount Rainier has a history of frequent and large explosive eruptions, it may indicate a higher level of risk for hikers due to the potential for ashfall, pyroclastic flows, or lahars (volcanic mudflows) that can pose dangers to human life.
Additionally, analyzing the timing and recurrence intervals of past eruptions can help estimate the likelihood of future eruptions. If the volcano has been relatively inactive for an extended period, it may suggest a lower immediate risk for hikers. However, it is essential to consider the potential for future eruptions and monitor any signs of volcanic unrest or changes in activity.
Furthermore, studying the extent and distribution of past volcanic deposits, such as lava flows or ash layers, can help identify areas that are more prone to hazards. This information can be used to establish exclusion zones or restrict access to certain hiking trails that may be closer to potential hazards.
Ultimately, by considering the history of Mount Rainier's eruptions and the associated hazards, authorities can make informed decisions regarding the safety of hiking around the volcano. It is crucial for hikers to stay updated with the latest information from local authorities, volcanic monitoring agencies, and park management to make responsible choices and ensure their safety when exploring the area.

Significado del acoplamiento entre CTE y FosOx, es de bioquimica si alguien me puede ayudar por favor
Answer:
La teoría quimiosmótica indica que la cadena de transporte de electrones (CTE) y el proceso de fosforilación oxidativa (FosOx) están acoplados por un gradiente de protones.
Explanation:
La teoría del acoplamiento quimiosmótico propuesta por Peter Dennis Mitchell permite entender cómo el ADP se fosforila a ATP en mitocondrias y cloroplastos. La energía que se libera durante la cadena del transporte de electrones es utilizada por la célula para crear un gradiente de protones a través de las membranas internas de mitocondrias y cloroplastos. Subsecuentemente, la energía potencial creada a partir de este proceso es liberada por el movimiento de protones a favor de un gradiente electroquímico. Finalmente, la energía potencial creada a partir del flujo de electrones es acoplada a la fosforilación oxidativa para sintetizar enlaces fosfato de alta energía en el ATP a partir de ADP y fosfato (Pi).

Explanation:
got it right on edg quiz (see pic)
hope this helps :)
All nutrients that enter the circulation are processed by the digestive and excretory systems simultaneously, with the exception of oxygen, which is taken in by the respiratory system. The correct answer is a) The digestive system fuels the cells and the excretory system rids the body of the cells’ waste.
What is the digestive and excretory system?Nutritive substances are absorbed by the digestive system, and any that are not are expelled. By continuously purging the blood, the excretory system works in tandem to remove metabolic waste products from cells throughout the body.
The digestive system takes in the nutrients and water from the diet. All across the body, the circulatory system delivers nutrition, water, and oxygen to cells. The respiratory system, the excretory system, and the skin all remove waste from the cells.
The excretory system filters the bloodstream for nutrients and gathers unneeded components in your urine for disposal, whereas the digestive system absorbs nutrients, collects them, and then eliminates the undigested solids (feces).
Therefore, the correct answer is a).
