A biogeochemical cycle is one of several natural cycles, in which conserved matter moves through the biotic and abiotic parts of an ecosystem. ... Each of these elements is circulated through the biotic components, which are the living parts of an ecosystem, and the abiotic components, which are the non-living parts.
___________ helps scientists understand processes in the natural world by providing simpler representations of those processes.
Answer:
models
Explanation:
Scientific models help scientists understand the processes in the natural world by providing simpler representations of those processes.
What are scientific models?A physical, mathematical, or conceptual representation of facts, data, processes, etc to be used as an aid for understanding the said facts, methods, or data are called scientific models.
These scientific models are used by scientists to comprehend or recognize various processes in our world by referencing their scientific knowledge which helps them to better understand and then explain any observable pattern.
Scientific models need to be consistent with the existing explanations or observations. Scientific models are based on facts but they cannot be considered ultimate facts themselves.
Scientific models can be consensus models, mental models, or expressed models based on their representation.
Therefore, the aid used by scientists to properly understand the natural world by providing simpler representations of those processes is called scientific models.

Why is it Important that cell membrane contain openings into cell ?
Answer:
Embedded in the lipid bilayer are large proteins, many of which transport ions and water-soluble molecules across the membrane. Some proteins in the plasma membrane form open pores, called membrane channels, which allow the free diffusion of ions into and out of the cell.
What is the most noticeable differences between the Hadeon period of
Earth with any other period of Earth?
Answer:
Hadean ("Hades-like") Era. This era began with the formation of the earth from dust and gas orbiting the Sun about 4.6 billion years ago. During this era the surface of the Earth was like popular visions about Hades: oceans of liquid rock, boiling sulfur, and impact craters everywhere, meanwhile, during, for example, the Cretaceous period, Earth's land assembled essentially into two continents, Laurasia in the north and Gondwana in the south. These were almost completely separated by the equatorial Tethys seaway, and the various segments of Laurasia and Gondwana had already started to rift apart, and there were oceans of seawater, teeming with life such as Mosasaurs and Ammonites. During the Cretaceous period, the land was hospitable and warm enough to support large numbers of lifeforms, including the dinosaurs.

Students in a science class were asked to investigate how missing or damaged organelles affect cellular homeostasis for cells found in muscle tissues. Which of the following questions should they ask to determine if these muscle cells are functioning properly? A. At what rate do the ribosomes of the cell need to work to produce enough glucose to meet the high energy needs of the cell? B. At what rate do the mitochondria of the cell need to convert glucose to usable energy molecules to meet the high energy needs of the cell? C. At what rate do the chloroplasts of the cell need to capture enough sunlight to meet the high energy needs of the cell? D. At what rate does the cell wall need to break down its carbohydrate structure to meet the high energy needs of the cell?
Answer:
B. At what rate do the mitochondria of the cell need to convert glucose to usable energy molecules to meet the high energy needs of the cell?
Explanation:
Organelles are specific in their functioning and hence, each organelle contributes its own quota to the cell's proper functioning. According to the question, a muscle tissue is being worked on to determine the effect of a missing or damaged organelle on its cell.
Mitochondria are organelles found in all eukaryotic living cells. They are the organelles responsible for the synthesis of ATP (energy) used by the cell as a result of the glucose that gets converted in them during cellular respiration.
Therefore, to determine if the muscle cells are functioning properly, the question that: At what rate do the mitochondria of the cell need to convert glucose to usable energy molecules to meet the high energy needs of the cell? should be asked.
Note that, Chloroplast and cell wall are not found in muscle cells, which is an animal cell. Likewise, ribosomes are not organelles for synthesis of glucose.

Answer:
You start to feel bad!
Explanation: When the balance is disrupted, the body system may not function properly.
When balance is disturbed the body function will not work properly.
What is organ system?
The body is organized at many stages that progress together. Organ systems are made up of tissues, which in turn are made up of tissues and organs.
The coordinated activity of an organ system's organs determines how well it functions. To process food, for instance, the digestive system's organs work together.
The coordinated operation of all organ systems, frequently coordinated by the endocrine and nervous systems, is necessary for the organism to survive.
The body is organized at many stages that progress together. Organ systems are made up of groups of organs with linked tasks. Organs are structures made up of two or more tissues arranged to perform a certain function.

Which will increase the rate of a chemical reaction?
adding a catalyst
decreasing the pressure
decreasing the temperature
removing a catalyst
Answer:
Addition of a catalyst
Explanation:
A catalyst tends to alter the rate of a chemical reaction thereby increasing the rate of the reaction
Adding a catalyst will increase the rate of a chemical reaction. Therefore, option (A) is correct.
What are the functions of catalyst?A substance known as a catalyst is one that, without being consumed during the reaction, accelerates or reduces the temperature or pressure required to initiate a chemical reaction.
A substance which when utilized in limited quantity in responses changes the pace of a reaction without being consumed in the actual response is known as an impetus and this peculiarity is known as Catalysis.
Without actually participating in the reaction, catalyst is used to speed it up. The reaction rate is sped up by catalyst, but the equilibrium constant remains unchanged.

Ribosomes produce proteins in cells; however, the type of protein that ribosomes produce depends greatly on where they can be found in the cell. Ribosomes found in the cytoplasm produce proteins that aid in chemical reactions. The other type of ribosomes are found in the _____________________ and produce proteins that ______________________.
A. Golgi Apparatus; repair broken organelles
B. Endoplasmic Reticulum; repair broken organelles
C. Endoplasmic Reticulum; store and transport nutrients
D. Golgi Apparatus; store and transport nutrients
The other type of ribosomes are found in the endoplasmic reticulum and produce proteins that store and transport nutrients.
What is an endoplasmic reticulum?
An endoplasmic reticulum is an membrane bound cell organelle found in the cell cytoplasm.
Its one end is connected to the nucleus and other end is connected to the golgi body.
Endoplasmic reticulum is a membranous structure. The membranes are flat and form a network (cisternae).
Endoplasmic reticulum is present in all the cells in the body except RBCs and spermatozoa.
Endoplasmic reticulum consists of two subunits:
Rough endoplasmic reticulum (RER) - ribosomes are present on the surface.Smooth endoplasmic reticulum (SER) - ribosomes are absent.Endoplasmic reticulum is important for protein synthesis and protein folding.
Endoplasmic reticulum is important in the storage of calcium.
It also helps in the detoxification of drugs and lipid metabolism.
Therefore, endoplasmic reticulum is crucial for the manufacturing, storage and transport of proteins.
