Chemiosmosos couples electron transport chain in the production of ATP in such a manner electrons are transfered from one molecule to another, and energy released in these electron transfers is used to form an electrochemical gradient.
In chemiosmosis, the energy stored in the gradient is used to synthesize ATP.

Hydrogen bonds in water molecules are formed between:
A. ions in solution between the molecules.
B. nuclei of adjacent molecules.
C. hydrogen and oxygen atoms of adjacent molecules.
D two hydrogen atoms of the same molecule.
E. two oxygen atoms of the same molecule.
Hydrogen bonds in water molecules are formed between hydrogen and oxygen atoms of adjacent molecules. Hence, option c is the correct answer for the statement.
What are different types of bonds?
There are various types of bonds, such as covalent bonds, hydrogen bonds, ionic bonds, etc. In covalent bonds, valence electrons are shared; hence, this bond is called a covalent bond. It is one of the strongest bonds. In ionic bonds, two ions, such as an anion and a cation, form a bond. An example is sodium chloride.
The hydrogen bond is not a covalent bond; it is made between oxygen and hydrogen, hydrogen and fluoride, etc. Inside water, each molecule is connected to another by hydrogen bonds. Hydrogen (H) and oxygen (O) of one water molecule make hydrogen bonds with hydrogen and oxygen of another water molecule. Inside a single water molecule, covalent bonds are present between hydrogen and oxygen.
Hence, a hydrogen bond is present between the hydrogen and oxygen atoms of adjacent water molecules. Option C is the correct answer .

Of the forms of friction listed above, which would a cyclist experience during this type of race?
1 & ll only
I, II, V
All of the above
Answer:
B. I, II, IV
(the option should be "IV" not "V")
Explanation:
Of the forms of friction listed, a cyclist experience "rolling friction, sliding friction and air resistance" during this type of race.
The rolling friction is known to be the type of friction that when a body rolls on a surface. In this type of friction, there is a force that tends to resist the motion. As the cyclist ride their bicycles, rolling friction occurs between the tyre of the bicycles and the surface of the road.
Sliding friction also occurs during this type of race. It's a contact that actually resists the sliding motion that occurs between two objects - an object and a surface.
Air resistance is the type of friction that occurs when objects move through air. It's a friction between air and an object. In this type of race, air resistance is experienced as the cyclists experience resistance from the air when the ride.

Describe the connection between Homeostasis and Growth and Development and then describe the connection between Homeostasis and Obtaining Energy.
Answer:
Homeostasis is critical to survival.
Growing through creative change is also critical. ... There is a constant dynamic tension between homeostasis and creative change.In biology, energy homeostasis, or the homeostatic control of energy balance, is a biological process that involves the coordinated homeostatic regulation of food intake (energy inflow) and energy expenditure (energy outflow). ... Fifty percent of the energy from glucose metabolism is immediately converted to heat.

Discuss how what you have learned about the respiratory system has caused you to see the environment around you differently. Are there specific activities or environments that you are more likely to avoid now? Explain why (or why not) your thinking about these activities or environments has changed.
Answer:
The respiratory system is directly connected to the external environment. More specifically, the gaseous environment around me can automatically find its way into the internal environment inside me.
The human respiratory system takes in air from the external environment. The purer the air is, the purer the content of its intake.
The system which keeps the lungs clean is found in the trachea which is lined with cells containing hair-like protrusions called cilia and also produces mucus and water droplets. The mucus and the cilia's activities combine to keep air passages hydrated and work together to trap dust, bacteria, and other foreign substances. An example of a foreign substance is heavy smoke from a building on fire. Other examples are cigarette smoke, heavy atmospheric dust such as is found in deserts. When these substances are inhaled, they can temporarily impede the efficiency of the cilia.
So it is important for one to avoid environments whose air is contaminated.
Because a contaminated environment translates to an impeded functioning of the respiratory system and a reduction in the quality of oxygen that reaches the bloodstream.

What force can stop gravity in a black hole?
Answer:
No force.
Explanation:
If the core is very massive (approximately 2.5 times more massive than the Sun), no known repulsive force inside a star can push back hard enough to prevent gravity from completely collapsing the core into a black hole.
Why are photosynthesis and cellular respiration often considered opposites? Photosynthesis produces twice as many ATP molecules as cellular respiration does. Photosynthesis produces twice as many ATP molecules as cellular respiration does. Photosynthesis occurs during the day, and cellular respiration occurs at night Photosynthesis occurs during the day, and cellular respiration occurs at night Oxygen is produced during photosynthesis and used during cellular respiration Oxygen is produced during photosynthesis and used during cellular respiration Water is released during photosynthesis and consumed during cellular respiration.
Answer:
Oxygen is produced during photosynthesis and used during cellular respiration
Explanation:
Photosynthesis and cellular respiration are two metabolic activities that are considered opposite of one another. This is because the reactants of one serves as the products of the other and vice versa.
- Photosynthesis is the process that occurs in green plants which utilizes CO2 and water in the presence of sunlight to produce glucose and oxygen as products.
- Cellular respiration, on the other hand, occurs in every living cell and uses glucose and oxygen to produce CO2 and water.
Hence, based on the options provided in this question, both processes are opposite of one another because Oxygen is produced during photosynthesis and used during cellular respiration.
