Answer:
Please mark as brainliest!!!
Explanation:
Answer;
Open system; can exchange both matter and energy; An example is a living organism such as human being, we actively interact with environment, which results in changes to both the environment and human being, for instance we eat to acquire energy.
Closed system; can exchange energy but not matter; An example is a saucepan, the saucepan allows energy transfer as the saucepan heats up and heats the contents inside it, putting a lid on it, prevents matter from entering and becomes a closed system.
Isolated system; Can exchange neither energy nor matter. For example is a thermos. if tea is poured into a thermos or an insulated container there is no exchange of heat or matter.

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.

Limiting factor definition:
Answer:
the definition of 'limiting factor' is...........In ecology, common limiting factor resources are environmental features that limit the growth, abundance, or distribution of an organism or a population of organisms in an ecosystem. ... The limiting factor also causes competition between individuals of a species population. For example, space is a limiting factor.

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.

What is described as the flow of positive charges that move from a positive terminal of the battery, through a circuit, and to the negative
terminal
O A conventional current
OB. electron flow
C. conventional circuit
D. electric circuit
Answer:
d. electric circuit
Explanation:
Electric current is the flow of electrons from the high potential energy position to the lower potential energy position. Current flow is the direction a positive current would be traveling, or the opposite direction that electrons actually flow. A closed loop containing current flow is called an electric circuit.

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 .

18. If the inside & outside of a cell are both isotonic, does water still
move across the cell membrane? Explain.
Answer: Yes
Explanation:
Isotonic means equally inside and outside the cell water can move out and in within not net movement.
