Oxygen is taken into the body from the environment, and carbon dioxide is removed from the body and released into the environment. Which
body system is responsible for exchanging gases with the environment? ( point)
A.endocrine
B.circulatory system
C. respiratory system
D. nervous system
Answer:
The correct answer would be in this case C) respiratory system. It is the main source where the process of gas exchange occurs, taking in oxygen and breathing out carbon dioxide into the rest of our surrounding environment.
The respiratory system is responsible for the exchange of gases with the atmosphere. So the correct option is C.
What is the respiratory system?
The network of organs and tissues that aids in breathing is known as the respiratory system. It consists of your blood vessels, lungs, and airways. The respiratory system also includes the muscles that propel your lungs. Together, these components help the body circulate oxygen and eliminate waste gases like carbon dioxide.
The respiratory system serves a variety of purposes. In addition to assisting with inhalation and exhalation, it:
Enables you to speak and smell.Raises the temperature of the air to that of your body and adds moisture to it to the proper degree of humidity.Provides your body's cells with oxygen.When you exhale, waste gases from your body, including carbon dioxide, are removed.Shields your airways from irritants and dangerous chemicals.
Therefore the correct option is C.

How does increasing the temperature affect the random motion of molecules?
Answer:
Raising temperature increases energy, resulting in faster speed of molecules.
Explanation:
Increasing the temperature introduces more energy to the system, which will cause the random motion of molecules to increase in speed.

HELPP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
In the cells of humans and other animals, a great deal of energy is dedicated to operating a pump that transports sodium (Na+) ions out of cells and potassium (K+) ions into cells. This transport creates a chemical and electrical gradient. Maintaining the proper balance of sodium and potassium is critical to ensuring that nerve cells work properly. Nerve cells drive muscle contractions—including heart muscles—and are responsible for animals’ abilities to sense their environment and for humans’ ability to think.
Scientists gain a better understanding of the sodium-potassium pump by creating models of what the pump accomplishes. Such models are used to examine many other complex processes as well.
This model of the sodium-potassium pump illustrates the process by which sodium is pumped out of cells and potassium is pumped in. The sodium-potassium pump moves the two different ions in opposite directions.
Where in a cell does this transport process take place?
A.
nucleus
B.
cell wall
C.
cell membrane
D.
vesicle
The Transport process takes place in cell membrane.
What is Transport?Cell transport describes the transportation of a material across a cell membrane. The chemical has the ability to enter or exit cells.
The plasma membrane and cell membrane are both permeable to different substances. The nature of the plasma membrane is quite selective.
Cell transport is very important for transport of molecules. There are two transport of cell transport of endocytosis and exocytosis.
Therefore, The Transport process takes place in cell membrane.

There are four types of consumers: omnivores, carnivores, herbivores and decomposers. Herbivores are living things that only eat plants to get the food and energy they need. Animals like whales, elephants, cows, pigs, rabbits, and horses are herbivores. Carnivores are living things that only eat meat.
What are proteins and how do you detect them ?
Answer:
Immunological-based methods such as quantitative enzyme-linked immunosorbent assays (ELISA), Western blotting and dot blotting are very common and sensitive assays for protein detection, and they use antibodies that react specifically with entire proteins or specific epitopes (e.g., fusion tags) after cell lysis.

Which of the following scenarios is most likely using the same type of cell transport as the sodium-potassium pump?
A.
A child's badly skinned knee heals rapidly.
B.
Animal cells control calcium levels to maintain proper signaling between cells.
C.
Cell activities remove fluid in a patient with swollen abdominal tissues.
D.
Minerals from food diffuse into an animal's intestine.
Answer:
option (A) is the correct.
Explanation:
I hope this helps you ♡♡
The statement which represents a scenario that most likely uses the same type of cell transport as the sodium-potassium pump is that a child's badly skinned knee heals rapidly. Thus, the correct option for this question is A.
What is the sodium-potassium pump?A sodium-potassium pump may be defined as a type of pump or channel or enzyme that is significantly found in the membrane of all animal cells. It performs several functions in cell physiology. The Na⁺/K⁺-ATPase enzyme is active. It effectively moves sodium and potassium ions against large concentration gradients.
According to the context of this question, the working mechanism of the sodium-potassium pump depends on the movement of two potassium ions into the cell where potassium levels are high and the pump of three sodium ions out of the cell and into the extracellular fluid. It plays an important role in contracting the cardiac muscle, kidney function, and nerve signaling.
Therefore, a child's badly skinned knee heals rapidly is the statement which represents a scenario that most likely uses the same type of cell transport as the sodium-potassium pump. Thus, the correct option for this question is A.

Describe why some water uses are called consumptive
Answer:
Consumptive rates are so high because water that is applied to a field is considered lost to the immediate water system. It either gets evaporated, used by the plants, or leaves the field as run-off. In addition, leaks or evaporation cause loss while water is being transported from the source to the field, often over great distances.

Is a process that tells cells to stop dividing if they touch each other
Answer:
contact inhibition.
Explanation:
This is how healthy cells know when to stop dividing. and a process called contact inhibition is when normal, healthy cells are touching other cells on all sides, they have a red light in the cell cycle and do not divide
I Hope This Helps!!!!
Answer:
cell cycle
Explanation:
The process then repeats in what is called the cell cycle. Cells regulate their division by communicating with each other using chemical signals from special proteins called cyclins. These signals act like switches to tell cells when to start dividing and later when to stop dividing. I don't understand what you are saying, but hope this helps!

3.
7
4.
12
Answer:
7
A pH value greater than 7 indicates a basic solution. The more the pH value exceeds 7, the more basic is the solution.
7 is the answer.
If the pH is 1, that means the substance is sour or acidic.
If it has a pH of 5, then it is not that acidic.
If something has a pH of 12, then it is almost completely basic.
If something has a pH of 7, then it is basic.
