O The most important source of water in the atmosphere is conduction from the oceans.
O Water reaches the land surface as rain or snow and is transported to the ocean by streams, rivers, and lakes.
O Liquid water from the Earth's surface is evaporated into a gaseous form and enters the atmosphere as water vapor.
Answer:
it's O n2. So, The most important source of water in the atmosphere is conduction...
Explanation:
Hope that helps! (Btw I did this test and got it correct)
The statement "The most important source of water in the atmosphere is conduction from the oceans" is not correct.
The most important source of water in the atmosphere is evaporation.
What is evaporation?Evaporation is a process through which a liquid transforms into a gas. It's a type of vaporization that occurs specifically at the surface of a liquid. Whenever a liquid gets heated the molecules, near its surface gain energy. Become more active. These energetic molecules tend to collide with each other resulting in some of them escaping from the liquids surface and entering the gas phase.
In terms of sourcing water for the atmosphere, evaporation of water from the Earths surface plays a role. Although water vapor does come from the oceans through conduction it's not the source that we rely on.

Why is it important the blood is constantly moving?
Answer:
Moving things in and out of the cell is an important role of the plasma membrane. It controls everything that enters and leaves the cell. There are two basic ways that substances can cross the plasma membrane: passive transport, which requires no energy; and active transport, which requires energy.

how are Metamorphic rocks with fine grains made and how did the composition of the Earth’s atmosphere cause changes to form the rock over time.
Answer:
A rock is a naturally formed, non-living Earth material. Rocks are made of minerals. ... A rock may be made of only one type of mineral. More often rocks are made of a mixture of different minerals.
Metamorphic rocks (changed rocks) are made when existing rocks are subjected to high temperatures and high pressures for long periods of time. Metamorphism (meta = change, morph = form) happens when molten rock intrudes other rocks and bakes the contact zone where the molten rock touches the preexisting rock. Metamorphism also happens when rocks are buried deeply during the process of mountain building. The kind of metamorphic rock made depends on the kind of original rock; for example, sandstone is turned to quartzite, shale is turned to slate, and limestone is turned to marble.
Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering.

Scientists are now studying human DNA in labs all over the world. Which are current goals for the scientists at these labs? Select three answers that apply. A. completing a full sequence of human DNA (the Human Genome Project) B. identifying the regions of human DNA that are transcribed into RNA C. identifying the regions of human DNA that bind to proteins D. analyzing the regions of human DNA that vary among individuals E. describing the molecular structure of human DNA
Answer:
B. identifying the regions of human DNA that are transcribed into RNA
C. identifying the regions of human DNA that bind to proteins
D. analyzing the regions of human DNA that vary among individuals
Explanation:
The double helix structure of the deoxyribonucleic acid (DNA) molecule was characterized and published in April 1953 by Francis Crick and James Watson. Moreover, the Human Genome Project was a project aimed at completing mapping and sequencing of the human genome. This project was completed and published in April 2003. Nowadays, scientists are focused on identifying which genes are expressed (i.e., transcribed into RNA) in specific cell types/tissues. For this purpose, it is imperative 1-to identify the promoter and enhancer regions that bind to specific proteins (transcription factors) in order to activate gene expression, and 2-to understand how genetic variation is related to gene expression patterns in specific cell types and/or in response to specific environmental stimuli.

Explain the difference between the effects of balanced and unbalanced forces on an object. To receive full credit you must mention net force and whether the motion will change or not.
Answer:
Balanced Forces acting on an object will not change the object's motion. Unbalanced Forces acting on an object will change the change the object's motion.The net force on an object is the combined effect (the sum) of all the pushing and pulling forces actually acting on the object. If the forces pushing or pulling on an object are not balanced (a net force acts) then the object will accelerate in the direction of the net force

When a cell has energy available, how can it store small amounts of that energy?
Answer:
When a cell has energy available, it can store small amounts of it by adding phosphate groups to ADP, producing ATP. ADP is like a rechargeable battery that powers the machinery of the cell. One way cells use the energy provided by ATP is to carry out active transport.

Answer:
D Flow of protons across an electrochemical gradient
Explanation:
The chloroplast adenosine triphosphate (ATP) synthase uses the electrochemical proton gradient generated by photosynthesis to produce ATP, the energy currency of all cells. Protons conducted through the membrane-embedded Fo motor drive ATP synthesis in the F1 head by rotary catalysis.
In chloroplasts, photosynthetic electron transport generates a proton gradient across the thylakoid membrane which then drives ATP synthesis via ATP synthase.
The light-induced electron transfer in photosynthesis drives protons into the thylakoid lumen. The excess protons flow out of the lumen through ATP synthase to generate ATP in the stroma.
Majority of ATP is produced by OXIDATION PHOSPHORYLATION. The generation of ATP by oxidation phosphorylation differs from the way ATP is produced during glycolysis.
Electrons are passed from one member of the transport chain to another in a series of redox reactions. Energy released in these reactions is captured as a proton gradient, which is then used to make ATP in a process called chemiosmosis.
D.Flow of protons across an electrochemical gradient
