Answer:

The correct answer would be "Warm and clean the air before it moves to the lungs."

The external opening of the respiratory system is formed by the nose and nasal passage.

The nasal cavity is lined with mucus and hairs.

The main functions of the nasal cavity moisturize, warm, and filter the air as it passes from nose to the lungs.

The noncyclic pathway is a FLOW of electrons from water, to photosystem II, to PHOTOSYSTEM I to NADPH. Energy is released as ELECTRONS move through the first electron transfer chain. This energy pumps HYDROGEN IONS into the thylakoid compartment, and then they power the formation of ATP as they flow back out. Sunlight provides the energy needed to keep this cycle going.

----------------------------------------------------------------------------------------------------

Luminous energy is trapped by chlorophyll in Photosystem II.
When the pigment molecules absorb light, electrons provided by water molecules get in a higher energy level.
The excited electrons go through the electron transport chain from Photosystem II to a less energetic level in photosystem I.
<em>When the excited electrons leave photosystem II, they are replaced by new electrons extracted from the water molecules. </em>
Luminous energy absorbed move the electrons from the photosystem I to another electron acceptor, from where they get transported again and used to produce NADPH molecules.
<em>When electrons leave Photosystem I, they are replaced by new electrons coming from photosystem II. </em>
When the water molecule breaks down, hydrogen ions remain in the thylakoid lumen, from where they are pumped to the stroma by the ATP synthase.
The released energy is used to produce ATP molecules.
Hydrogen ions go back from the stroma to the thylakoid compartment.

The final products are oxygen, ATP, and NADPH.

50% of the planets are made mainly of gas true or false

ella [17]

Answer: I think the answer is true

Explanation: If you think about it, the terrestial planets ( being venus, earth, mars, and mercury) are made up very little gas which are carbon dioxide, nitrogen and oxygen, and the gas giants ( being jupiter, saturn, neptune, and uranus) have gases such as hydrogen and helium. Thus meaning, the terrestial planets could be a part of it and the gas giants are the most. So yes, the answer is true.

Why does the United States purchase oil from other countries and the problem this sometimes causes

defon

Answer:

The oil produced in United States is light and low sulfur content and they do not have proper processing facilities, hence purchase it from other countries.

Explanation:

About 9.93 million barrels per day U.S purchase oil from 86 countries. Because the crude oil present is not homogeneous in nature. It is very light in nature with low sulfur content or may be high,this particular factor depends upon the method of the refining. Most of the oil are being exported by the Saudi Arabia and then comes Russia followed by Iraq. Despite the collapse in price, U.S. dependence on foreign oil should continue to decrease.
