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.

Animals such as foxes and cats often prey on rabbits. Based on the growth curve of the rabbit population, what
might have happened if a group of predators moved into the rabbits habitat during the tenth generation and
began eating the rabbits?
Answer:
If this happened that would affect to amount of food the other predators got, eventually causing decreases in their species.
Explanation:
If a group of predators moved into the rabbit's habitat during the tenth generation and began eating the rabbits, it would definitely affect the amount of food and other resources that are available for other predators that directly or indirectly depend on the rabbit's population.
What is a Habitat?A habitat may be defined as a type of natural environment for which a particular species is best adapted due to natural selection. In this natural environment, the basic demands of an organism are fulfilled like food, space, mating partner, etc.
When a group of predators starts eating the rabbits, the population of rabbits gradually decreases. Due to this, the other predators of the same species feel the scarcity of food and resources. As a result of this, their number or population also declines slowly or adapted to other species.
Therefore, it would definitely affect the amount of food and other resources that are available for other predators that directly or indirectly depend on the rabbit population.

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!

Answer: Raymond Wang: How germs travel on planes – and how we can stop them
1. After completing the unit and watching the video, explain how the unit about oceans and the video about germs on a plane relate?
In his video Raymond explains how the diseases are transmitted through planes from one country to another and the difficulties faced to prevent the spread of diseases due to the air circulation in the planes. It is always difficult to screen the person with disease and prevent them from getting into the plane since the air circulates in the conventional cabins. When a person sneezes, the air will get swirled multiple times and spread the disease.
2. Using examples from the video, explain why it is difficult to keep people who are sick off of planes.
It’s difficult to pre-screen for diseases. When someone goes on a plane, they could be sick and actually be in this latency period in which they could have the disease but not exhibit any symptoms and could possibly spread the disease to many other people.
3. How does Wang illustrate what happens in a conventional airplane cabin when someone sneezes?
He illustrates how the air is just being circulated throughout the plane. When someone sneezes, the air is just being circulated into the air. This means that everyone on that plane has breathed in that person’s sneeze because it’s such a compact place.
Answer:
4.
Explanation:
Describe Wang’s solution for easily preventing the spread of disease on airplanes? What does “flow,” a word seen in the unit, have to do with his solution? The thing he made to prevent people from getting sneezes in their face is by making the bacteria flow straight towards the filters, so no one gets the bacteria in their faces.

A hormone signals through a G protein-coupled receptor as shown in the diagram. After the production of IP3, which of these events will MOST quickly stop the transduction of the signal?
A. the hydrolysis of IP3
B. the hydrolysis of GTP
C. the hydrolysis of PIP2
D. the hydrolysis of the hormone
Answer: The answer is A
Explanation: Took the test lol
The quickest halt to the signal transduction process after IP3 production occurs through the hydrolysis of IP3 itself, as option A.
The hydrolysis of IP3 results in the quickest termination of the signal transduction pathway among the available alternatives. A series of actions are triggered by IP3, which causes the release of calcium ions from intracellular reserves. IP3 is hydrolyzed by phosphatases, which halts the calcium release and prevents protracted signaling.
Even while the hydrolysis of GTP and PIP2 is a necessary step in the cessation of G protein-coupled receptor signaling, it happens later and does not have the same rapid effects as IP3 hydrolysis. The hormone's own breakdown is not a known mechanism for halting signal transmission.
