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.
Therefore, When balance is disturbed the body function will not work properly.

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.
___________ 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.

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.

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.

What usually happens when new evidence is discovered that is not already explained in an existing theory? Group of answer choices The existing theory is discarded, and a new theory is developed. Scientists choose sides and either support the existing theory or the new evidence. The theory is adapted to account for the new evidence.
Answer:
The best answer to the question would be - The theory is adapted to account for the new evidence.
Explanation:
If a piece of new scientific evidence is discovered for an already existing scientific theory that is already not explained in the theory it would be lead to the modification of the theory in order to make the theory so it can explain the newly find evidence.
If the theory can not be modified to fit the new scientific evidence the given theory is rejected ultimately. But more often theories are modified to explain the newer findings.
Thus, the best answer to the question would be - The theory is adapted to account for the new evidence.
What usually happens when new evidence is discovered that is not already explained in an existing theory is that more scientific evidence would be gathered about it.
Needless to say, a scientific theory may be modified and rejected if it cannot be made to fit the new findings; in such circumstances, a more accurate theory is then requiredAccepted theories may however, be modified or overturned as new evidence Scientists are likely to accept a new or modified theory if it explains everything the old theory did and more.
Scientific evidenceScientific evidence is evidence which serves to either support or counter a scientific theory or hypothesis.

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.
