Answer:
B
Explanation:
A planet is at equal distance from two stars, Star 1 and Star 2. If both stars have the same mass,
they will not pull each other with a gravitational force
they will pull the planet with equal gravitational force
Star 1 will pull the planet with a greater gravitational force than Star 2
Star 2 will pull the planet with a greater gravitational force than Star 1
Answer:
In this situation both o the stars will pull the planet with equal gravitational force.
Explanation:
The reason behind this is that gravity works according to the mass an object has. Therefore if we have two corpses with the same amount of mass they are going to pull the objects with the same strength. Now, in our case, they have a planet between both of them. Thus, they are going to pull it to them with the same gravitational force because they have the same mass, and are at the same distance. If one of them had a bigger mass that would pull the planet with more gravitational force, as well as if that star was closer to the planet.

What part of the respiratory tract is considered the respiratory zone?
A. Bronchioles
B. Larynx
C. Trachea
D. Alveoli
Answer:
D. Alveoli
Explanation:
Functionally, the respiratory system is separated into a conducting zone and respiratory zone:
Conducting zone consists of the nose, pharynx, larynx, trachea, bronchi, and bronchioles. These structures form a continuous passageway for air to move in and out of the lungs.
Respiratory zone is found deep inside the lungs and is made up of the respiratory bronchioles, alveolar ducts, and alveoli. These thin-walled structures allow inhaled oxygen (O2) to diffuse into the lung capillaries in exchange for carbon dioxide (CO2).
The respiratory zone begins where the terminal bronchioles join a respiratory bronchiole, the smallest type of bronchiole, which then leads to an alveolar duct, opening into a cluster of alveoli.
Answer:
Yep, the correct answer is D.) Alveoli
Explanation:
Hope this helped you!Have a great day(:

What role do the oceans play in moderating climate change?
Group of answer choices
A. Oceans help to reduce the level of water vapor in the atmosphere through condensation.
B. Oceans absorb about 40% of the methane out of the atmosphere that has been produced by rice paddies and livestock.
C, Oceans remove about 25% of the atmospheric carbon dioxide produced by humans.
D. Oceans reflect sunlight back into space before the ultraviolet wavelengths are converted into infrared radiation.
The role that the oceans play in moderating climate change is as follows:
Oceans remove about 25% of the atmospheric carbon dioxide produced by humans.Thus, the correct option for this question is C.
What is Climatic change?Climatic change may be defined as a type of process that significantly involves long-term alterations in the temperature and weather pattern of a particular location. These alterations are completely natural and rely upon the solar cycle.
The role of the oceans is determined by the fact that they regulate the climate of particular locations by absorbing 25-30% of the carbon produced by humans in the environment. Due to this, they are considered the largest store of carbon accounting for approximately 83% of the global carbon cycle.
Therefore, oceans remove about 25% of the atmospheric carbon dioxide produced by humans is the statement that represents the role of oceans that play in moderating climate change. Thus, the correct option for this question is C.

Explain why the forest ecosystem is a system.
Answer:
Like all ecosystems, forests consist of many interacting parts. They include living organisms such as plants, animals, and fungi. Forests also include non-living components that these organisms depend on, such as the soil and climate. As stated in the article, one change, such as pollution, can cause a ripple effect through the ecosystem. Dying lichens are one of the earliest signs of pollution. In turn, the loss of the lichens can cause a decline in species that rely on the lichens for survival.
Explanation:
That is the sample answer.
