Solar energy: Energy from the sun
Evaporation: The process by which water changes from a liquid to a gas or vapor.
Condensation: Water which collects as droplets on a cold surface when humid air is in contact with it. (MAKES CLOUDS)

Question 1 of 20
Which statement describes the difference between covalent bonds and Van
der Waals forces?
O A. Covalent bonds form from the attraction of positive ions and
freely moving electrons, while Van der Waals forces cause an
attraction between nonpolar molecules.
B. Covalent bonds form when there is an attraction between
nonpolar molecules, while Van der Waals forces cause two atoms
to share valence electrons.
C. Covalent bonds occur when two atoms share valence electrons,
while Van der Waals forces cause an attraction between positive
Answer:
Covalent bonds form when two atoms share valence electrons,
while Van der Waals forces cause an attraction between nonpolar
molecules
Explanation:
A covalent bond is said to be formed when two atoms of the same or different elements share electrons. In an ordinary covalent bond, each bonding atom contributes one valence electron while in a dative covalent bond only one of the bonding atoms provides the shared pair of electrons.
Van Der Waals forces is the major intermolecular interaction between non polar compounds. Van Der Waals forces " are caused by correlations in the fluctuating polarizations of nearby particles"(Wikipedia).
Answer:
Covalent bonds form when two atoms share valence electrons, while Van der Waals forces cause an attraction between nonpolar molecules.

Propose a series of equations to represent the equilibria described in the prelab discussion involving the transport of oxygen from the lungs to the cells and the carbon dioxide back to the lungs. Use Hb for deoxyhemoglobin, HbOx for the oxyhemoglobin, and HbCO2 for the carbon dioxide- hemoglobin structure.
Answer:
hello your question is poorly written attached below is the complete question
answer :
Hemoglobin + oxygen ⇄ oxyhemoglobin
[tex]Hb_{4}(aq) + 4O_{2}[/tex] ⇄ [tex]Hb_{4}O_{8}[/tex]
Explanation:
The series of equation to represent the equilibria described in the prelab discussion can be written as :
Hemoglobin + oxygen ⇄ oxyhemoglobin

What are some whole, fossilized animals preserved in?
which of the following is an indicator of good water quality?
high levels of nitrates
high levels of phosphates
zero turbidity
all of the above
Answer:
all of above
Explanation:
all of the above
Answer:
Zero Turbidity
Explanation:
High phostphate levels cause excessive algea growth and a decreased level of dissolved oxygen. High levels of nitrates are caused by animal or human waste and the overuse of chemical fertilizers. Low turbidity causes the water to be more clear so zero turbidity is the only right answer. I got it right on my test too

Messenger RNA created through the process of transcription moves from the:
A: nucleus out to the ribosomes where translation takes place
B: ribosomes into the nucleus where
translation takes place
C: nucleus out to the lysosomes where translation takes place
D: ribosomes out to the nucleus where translation takes place
Answer: a
Explanation: transcription takes place in the nucleus. RNA leaves the nucleus to go to the ribosome where translation occurs.
Part D A scientist comes up with an idea to reintroduce a shark that eats lionfish into the Atlantic Ocean. What are the possible benefits and risks of this idea? In your answer, state two questions you’d ask the scientist before agreeing to the plan.
Answer:
The shark may balance out the lionfish population. However, its presence in the ocean may also negatively affect other organisms. The shark may start preying on natural species, leaving little food for native predators. Two questions to ask the scientist are, Does this shark have any natural predators in the Atlantic Ocean to help control its population numbers? and What other organisms does the shark eat?
Explanation:
i got this from edmentum-
Although some species of grouper and shark may be able to eat them, lionfish have relatively few predators in the area they have invaded because of their deadly spines. Although lionfish are widely distributed, most sharks won't readily eat them.
What eats lionfish into the Atlantic Ocean?The shark might maintain lionfish populations in balance. Its presence in the ocean, however, might also have a harmful impact on other organisms. It's possible that the shark will start eating native animals, leaving little food for them.
Do this shark's natural predators in the Atlantic Ocean aid to regulate its population numbers? Are two queries to put to the expert. What other kinds of creatures does the shark consume?
Therefore, Because the Moray was discovered in a location where divers would not have been searching, this is the first confirmed instance of natural predation of the invasive lionfish in the Atlantic Ocean.

Explanation:
Historically many ideas concerning cells have been examined leaving three to be incorporated into the cell theory which of the following is not part of the cell theory
Answer:all life form contains more than one cell
Explanation: thats the only question that's not true
Historically, many ideas concerning cells have been examined, leaving three to be incorporated into the cell theory except that all life forms are made up of more than one cell as the life forms can either be single or multicellular.
What is the significance of the theory behind the cell?Cell theory, a foundational concept in biology, states that all living organisms are made of cells, and these cells come from pre-existing cells and not from anywhere else. All these postulates support the idea that cells are the basic building blocks of life and that life can only be generated through the replication process.
Hence, historically, many ideas concerning cells have been examined, leaving three to be incorporated into the cell theory except that all life forms are made up of more than one cell as the life forms can either be single or multicellular.

The cholesterol associated with membranes
- helps stabilize the membrane at body temperature
- is attached to proteins and extends into the environment surrounding the cell
- both a and c
- is an abnormality resulting from a diet high in cholesterol
Answer:
b) It interferes with the movements of the fatty acid tails of the phospholipids.
Explanation:
Cholesterol has many important functions, including its role in membrane permeability, especially the cell membrane, and its role in metabolism. Cholesterol reduces the permeability of lipid membranes. ... Cholesterol helps to restrict the passage of molecules by increasing the packing of phospholipids. Steroid molecule that makes membranes more fluid at low temps and more ordered at high temps.
- Flat, rigid, carbon rings interfere with the movement of phospholipids.
- Smaller and less amphipathic lipid that is only found in animals.
- Sandwiched between fatty acid tails of phospholipids.
